PDF Transcription For This Episode


That was my lovely daughter, Maha Blandi.  Welcome to the Blandi coffee podcast, all coffee no sugar.  I’m your host Patrizio Blandi; I’m the owner and coffee roaster for Blandi coffee.  This is episode number three on how to make a consistent coffee even if you are novice.  This is part two of a four part series.  In part two, we are going to be talking about the coffee grinder.  Before I get in to the show, I just want to you talk to you about, a few exciting things that happened between episode two and this episode.

I’ve had a five star review which is very exciting, this five star review is by electric brewer, he basically said “Finally, a go to coffee podcast for roasting, brewing and business.”  He wrote in there as well, “I’ve got the roasting bug and have sourced iTunes to find resources to improve my roasting and my brewing coffee.   I’m also looking to start a small roasting business and the more resources the better.  Keep up the good work and looking forward to more episodes, subscribed”. 

Thank you electric brewer for that five star review and a very positive review.  What electric brewer has done if he’s found that this podcast is going to be a place where he can find information that’s going to help him with his business, with the way he makes coffee and if it does help you, like it’s going to help electric brewer, by writing a review on iTunes, it’s going to make this more visible to more people.  Therefore, it’s going to help more people and if it’s helping you when you think this is going to help others review in iTunes, because yes, it does improve my ranking, the main thing here is we want to expose it to more people. 

And the more people can find it, the more get people can help.  If you do find this podcast useful, it’s helping you in some way and you want to help other people review it and it will be found to more people.  The other exciting thing that’s happened is, I’ve been contacted by a listener. This listener, his name is Vito Blandi, I don’t know if I’m related to him, we both have agreed unofficially that we are cousins someway, somehow sort of said, “yeah we are cousins”. 

It was very excited to hear from Vito Blandi, came into contact with the podcast from his sister, alerting him that there’s a Blandi coffee podcast.  So he’s listened to it and he’s emailed me about the podcast.  He lives in New York, so look; I want to give his business a plug.  He’s got a business in New York, it’s Smithtown Appliances, and it’s been there for over forty years.  If you need an appliance go see him first and say, “I’ve heard you on the Blandi Coffee podcast”.  I’ve given Vito a sort of a plug.  He has spent his time contacting me and giving me some information about my podcast.  This is the very least I can do for him.  All that aside now and getting stuck into this episode.

On the last episode, which was episode two, I talked about coffee beans and the importance of having the right coffee bean, if you haven’t listened to episode two, please go back and listen to that because that is the foundation to making consistent coffee every time. 

Now, building the base of having a very good coffee, we’ve got the concrete laid down, now we can build on top of that.  It doesn’t matter what we build on it, we’ve laid a very good foundation, so that’s the importance of having a great fresh premium coffee.  Once we’ve got, that’s something we can forget about.  We don’t have to go back and worry about what the coffee is doing, we know it’s not the coffee because we found it.  We spent the time locating it and looking at the features that we need to have a great consistent coffee.  So once we’ve got that down packed, we don’t need to worry about the coffee anymore.  We need to go to this part to the coffee grinder.  Having a consistent coffee then anything that happens in this stage, we can tell there is a problem on the way we grind the coffee.  As we move forward to each topic we know that the coffee is good.  We know our grinder is good.  We move to the coffee machine.  So as we progress through those top different stages, we’re going to eliminate all these variables and then by the time we get to the end there’s your perfect coffee.

Choosing the correct coffee grinder is very important.  It’s the most important tool that you can have.  Whether you’re using it at home making coffee or you’re using it in your business, this is the most important tool to have. 

The coffee grinder’s job is to produce an undisturbed consistent size grounded coffee grounds which is repeatable every time with minimal variations between each grind. 

Now this is a statement.  This is a very important statement and I will repeat it.  The coffee grinder’s job is to produce an undisturbed consistent size grounded coffee grounds which is repeatable every time with minimal variations between each grind.  What does that mean?  We have a coffee grinder.  Its job is to convert the whole bean into grounded coffee.  That’s the job.  Now it must do that undisturbed so whatever flavor the white taste chemical compounds in the coffee or the elements should not be changed.  Whatever we have in the beginning we should have at the end.  That’s in ideal world. It doesn’t happen.  That’s the job of the coffee grinder.  Consistent size grounded coffee grounds. 

Blade grinders, they’re useless.  They’re rubbish.  I don’t need to spend any more time on blade grinders.  All I need to tell you is its rubbish.  I’ll give you an understanding why it’s rubbish and should not be used.  If you’re using it, stop using it. 

In a blade grinder you will never be able to repeat the same grind. It’s a random process.  Once that blade spins, it’s just going to keep chopping.  Whatever the particles is going to be from a very coarse to medium and to fine.  It’s not a consistent grind as you are getting a consistent particle size as well.  And in that statement I said, repeatable every time, and that’s something you won’t get from a blade grinder.  From a burr grinder and from a conical grinder or flat lay grinder, you’re going to get that repeatability, it’s because there is a gap  that is maintained, there is a knob that you turn to adjust  the spacing between the blades and that space in the blades will not change.  And that’s another feature of a coffee grinder.  It’s able to keep the space between the blades consistent.  That’s going to give you a consistent grind as well. 

In an ideal world, it should not be disturbed.  Without leaving the ideal world the grounded coffee will be disturbed.  When it’s converted from a whole bean down to grounded coffee ground. 

What we need to do is eliminate the disturbance of the coffee.  And that’s because of the variables.  Again there are variables in the coffee grinder.  That’s going to introduce variables into our coffee so we need to eliminate it and reduce and not introduce new ones.   

Buying the incorrect grinder can impact your results of your perfect cup of coffee.  You’ll probably spending too much money on your coffee grinder depending on your use or, for example, if you’re using a coffee grinder at home you don’t need to spend thousands of dollars on a coffee grinder.  You’re only going to make one cup of coffee or make maybe two cups of coffee in the morning and you won’t use it for the rest of the day.  So you don’t need a commercial size grinder.  You just need a grinder that is going to give you a consistent size grounds that is for example, a flat lay or burr grinder and it doesn’t have much to it.  You don’t need to spend thousands of dollars.  You can pull it underneath a thousand dollars. 

Depending on what you’re going to use, the grinder four is for an espresso, for a plunger or is it for Turkish coffee, now depending on your usage, there’s a rule of thumb.  The coarser the coffee grounds are, the cheaper it is.  You can get away with cheap grinders because it doesn’t need to ground it for a long time.  It just needs to convert from a whole bean to a coarse coffee grounds.  The finer you get, for example, coarse coffee grounds can be used for a plunger, for dropped coffee, for filtered coffee, as you move out, for example, going to a mocha top, like a stove top coffee maker to an espresso coffee machine, it’s going to get more expensive because we need finer grounds.  When we get to Turkish coffee, its grounds are so fine it’s like flour.  We need to have a very good grinder and that’s very expensive. 

Depending on the volume you use on grounding that coffee, the more expensive it is because we’re going to a very fine grind, therefore it’s going to stay in the blade longer.  And that means it’s going to heat up the coffee.  So you need to have a well-designed blade, a well-designed grinder to be able to grind coffee for Turkish coffee.  So that’s a rule of thumb.  From coarse being the cheapest to Turkish style coffee being the most expensive.  It depends on your usage.  Domestic, it’s something cheaper.  Commercial, it depends on your volume.  Low volume, you can get away with something like from a thousand dollars.  As you go to high volume you need to spend at least fifteen hundred to over two thousand dollars depending on your volume.  That’s the scenario. 

You don’t need that.  You don’t have to spend a lot of money.  The situation is, if you buy a wrong coffee grinder, one, you’ll be spending too much money on something that you don’t need. Or two, you’ll be buying something that’s not suitable for your situation.  The variables that we’re going to encounter, there are three variables.  A direct variable, an indirect variable, and new variables. 

Direct variables are variables that are directly affected be the choice of the grinder that you buy that are the features that you choose.  So for example, the blade that it uses, the source of the motor.  How easy is it to clean?  These are all the features and the design of the coffee grinder that’s going to affect what you’re going to get out.  Is it on demand grinding or a storage grind?  So there are things that you need to look out for.  That is direct.  So that means it’s the design of it.  You can’t change it.  So when you look for something, you can look for the, what it’s designed.  Is it going to give me an on demand grind or is it going to store it when the coffee gets grounded and gets stored and you flick it into your grip handle.  Is it easy for you to remove things and access the blades, remove the coffee beans?

Indirect variables are variable that comes from the grinder itself.  Like for example, the built quality, efficiency of the grinder that gives you negative effects.  They are variables but we can eliminate these variables by choosing the purpose we got to use it for.  That’s mainly the built quality of the coffee grinder.

New variables, introduced by you.  Now this is how you look after the coffee grinder.  The way you grind the coffee.  How you maintain and look after the coffee grinder.  The way you use the coffee grinder.  And everything that is required to produce grounded coffee that you touch that’s going to give you variables.  Now, example of variables, direct variables are coffee bean hopper easy to remove.  Is the coffee grinder on demand dozer or does it have a storage bin that coffee grounds get dumped into it and then you can manually dose your group handle.  What blades is it using?  Is it easy access to the blades so you can clean it or you can replace them as well? 

Indirect variables are the heating up of the blades can affect the output of your coffee.  Heating up of the middle parts in the coffee grinder.  The heat transfer to the grinder chamber.  They are the indirect variables.

New variables.  Cleaning the coffee grinder.  The sharpness of the blade teeth.  Coffee residue that’s left in the coffee grinder if you don’t clean it.  The hopper size.  The bigger the coffee grinder you get, it’s going to have a bigger capacity for you to put more coffee beans.  That is, for larger volume places.  So if you go for one kilo of coffee for a day and you have a capacity of two kilos in your hopper, while you’re filling that up and your coffee bean at the whole day and there’s going to be some left over that’s going to introduce variables.  So you only need to put the amount of coffee you’re going to use for the next couple of hours. 

There are six important features that you must have on a coffee grinder.   There are more but these six is your twenty percent that’s going to give you eighty percent results.  So this is point twenty percent on the features that you can get on coffee grinders but it’s going to give you the greatest results. 

There are other features that you can get on a coffee grinder but the amount of money you need to spend to get those features are going to be greater but it can give you little results.  It’s not necessary to get all the bills on we saw on a coffee grinder unless you have heaps of money you want to spend.  If you have a limited budget, I think these are the six key features to have. 

You can use these six key features even for domestic use because you don’t have to use all six.  If you use all these six features when selecting a coffee grinder it’s going to give you great results.  And on domestic use, it depends on your capacity, on your volume and usage.  If you’re using it quite often and you’re doing very fine grinding then you need to have all six features.  These are not in order.  So I’m going to start with number one.

Removable coffee bean hopper.  This is important because you want to be able to remove the coffee bean hopper to store your coffee beans after use.  So you can putting them on an airtight container, store them away for the next time you need to use the coffee grinder.  The easy way to do this on a coffee bean hopper is like a little shutter that you slide and it shuts off the supply of the coffee beans.  So whatever is in the coffee bean hopper when you push that lever in, it shuts it off so you can easily remove the hopper of the grinder.  The coffee beans won’t pour.  It’s very easy.  It saves you pouring the coffee beans out.  It makes it easier for you to remove the hopper.  It takes very little time, you can slide it over, you can put the beans into your airtight container, store them away. 

There’s going to be coffee beans left-over inside the grinder with later.  There’s very little coffee beans left over.  Instead of throwing that away you can store that in a separate container and you can use that the next day when you’re setting up your coffee grinder.  By doing that, you’re not exposing your coffee beans to air.  So at the end of the day or after using the coffee grinder by removing the hopper there’s no more coffee beans.  If you listen to episode two the idea is not to expose your coffee beans to air for more than three hours.  So if you’re at home grinding coffee, the best thing to do is put as much as you need to use for you to make one coffee. 

The second feature you have on the coffee grinder is the demand dozer. What is an on demand dozer? An on demand dozer has no storage. So when you grind the coffee, the only way for you to grind the coffee is to push your handle onto a button, it turns on the motor, it grinds the coffee and it falls directly into your group handle, there is no storage.

There are coffee grinders out there that have storage facility. When you turn on the grinder it automatically grinds. Some grinders as you reach a particular volume, it starts to grind the coffee automatically and then would shut off at a particular volume again. So there is no way to shut it off unless you shut the machine off manually. So you’re going to grind a whole heap of coffee, if you have listened to my second episode, you should have used coffee within 3 minutes after grinding. So if you are grinding a whole container of coffee and you don’t use it within three minutes then you are introducing variables. So that is an important feature you have is an on demand dozer. And also another thing with those storage bins, where the coffee gets dumped into a storage area.

When you manually dump the coffee even when you grind as much coffee as you want, the thing is it is leaving the residue. There is much you can manually dump into your group handle. There are gaps that stop you from completely emptying the storage bin so there will be coffee leftovers. If you do grind coffee for another ten minutes, you’re going to have some old coffee there. And then when you grind the coffee on top of it, it’s going to come out. That’s another variable.

The third feature you should look out for is the easy access to blades. The reason why we want to have an easy access to blades is so we can clean the blades daily and then it really depends to your volume but if you have a routine cleaning every day, it’s better because you can easily remove the hopper and you can use a hard bristle brush to clean the blades. And then you have the grinder completely finish and that’s like a two-minute process maybe a five minute process.

I use a Masa grinder. It’s a major electronic grinder. It’s very easy for you to get access to the blades. There’s a knob when you get the coffee bean hopper that you use to select a finer grind or coarser grind. If you screw that to the coarser grind and you keep screwing it up to come up to the adjustment knob you will have one set of blades and then the coffee grinder it’s going to have another set. You will have a rotating blade and then the fixed blade on the adjustment knob. It’s that easy. Something to be aware of, there are 4 springs that keep the tension on that blade when the grinder is grinding so the adjustment stays within that specific grind selection that you made. So when you do move, just be careful those four springs, you don’t lose them.

If you use a hard bristle brush to remove any remaining coffee on the blades to remove any residue on the blades and then clean inside the grinding chamber.

The fourth important feature to have in the coffee grinder is the blade.

The three types of blades you have, blades, just like blender type blade, a helicopter blade which is spinning around or you can have a burr blade or you can have a flat conical blade. They’re the three different types.

Now the first type you won’t see in commercial use or you mainly see it in domestic. What I want to say about the blade grinder is chuck it away. There is not really much more to say but I explain the reasons why I’m saying its rubbish. The best way to say this, if you look at a helicopter you have the gap between the ground and the bottom of the blade. If you walk within that range, or if the coffee bean forcing that range, nothing happens. The same thing with coffee beans. Once that blade hits the coffee and cuts the coffee, all the particles are going to fall below that blade.

Depending on the actual size of those coffee beans when it gets cut, chopped it will be underneath the blades and it won’t get chopped anymore. If it’s getting exposed to the blade, it’s going to be chopped again. And it’s going to full blow the blade. As you are grinding the coffee it’s going to get higher and higher, and it’s going to get above blade range and it’s going to keep chopping it. It can only chop so much. Once you reach the capacity of that blade grinder it’s just going to keep spinning and chopping the same thing so that’s going to introduce heat.

So you’re going to have this very high-velocity spinning blade spinning on top of coffee. It’s not going anywhere. There’s no chamber where it gets dumped anywhere. It just stays within the grinder itself. There is no way for it to be removed. As I explained, and you are going to get this different coffee grind size.

You’re going to get coarse, very coarse, medium coarse and fine, very fine.  You’re going to get that inconsistency.  And to repeat the same grind size is impossible.  It’s a very random thing that happens.  The best thing to look out for is a burr grinder or you can get a flat slash conical blade grinder as well.  The flat grinder is one of the best to get and depending on your use.  A burr grinder is sufficient for domestic and to low volume.  The commercial use going into your high volume and more consistency you need to get a conical flat blade grinder. 

The difference between a conical blade and your just normal blade grinder. In a conical blade grinder, there’s two blades.  If you put them together, you’ll see this, with a coffee beans for, there’s a big gap.  The big gap is to actually bring the coffee bean into the blade.  If you look at blades, it’s got a bigger gap.  A bigger gap is so the coffee bean fall into the blades and then the way the teeth is designed is to gradually drag it through from that big gap down to the smaller gap. It’s slowly pushing it towards the outer side of the blade where it gets dumped in to a chamber.  And when it’s spinning around it doesn’t stay there as it grinds, it gets pushed to the other side of the blade eventually falling out and then falling into the group handle where your storage bin. 

The gap between the two blades is what you adjust.  The bigger the gap you have the coarser you’re going to get.  It’s going to go to the process where it’s like a slant.  It goes from a big gap to a smaller gap.  That smaller gap where it forces out is your end result that’s always going to give you a similar coffee grind size.  Very similar.  That’s what you’re adjusting in the grinder.  You’re adjusting the two blades.  It’s going to get close together or further away.  If you get it close together, it’s finer, the further away you get, the coarser it’s going to get. 

Now the fifth important feature on a coffee grinder is the motor capacity.  Now it depends on your usage.  For domestic use, you don’t need to have the commercial model on your coffee grinder because you only make one or two coffees in the morning and not going to use it for the rest of the day.  Maybe at night when you come home.  In a commercial environment for example in a café, that coffee grinder is continually being used.  It depends on the volume.  It could be always be running from day to night. Now you need to have the motor that’s going to handle that use. 

If you have a very small motor, for example, you’re using a domestic grinder in a commercial use, you’re going to have a small motor which is going to heat up, it’s not built to continually run.  It’s just short burst and it is designed to make the one or two coffees and then it’ll be turned off.  It’s not designed to do any more than that in that continuous burst.  It is designed to be able to handle the load, a continual load, a continual use.  Depending on the quality of the grinder, there will be features into the coffee grinder where it’s going to have ventilation, it’s going to cool down the motor when it gets to a certain temperature or continually cool the motor at all times.  In a high volume situation, you want to be able to grind the coffee more quickly.   The blades are going to be bigger; it’s going to chew for more coffee.  It’s going to grind more coffee at one particular time. 

It’s going to give you high volumes of grounded coffee; you need the biggest size of motor to handle that load on to the motor so you can grind the coffee more quickly and more volume.  The sixth important features to have on a coffee grinder is the consistent grind size of your coffee.  There are two methods of selecting grind size.  There is a step and a step less selection in a step ground selection method.  It has a needle, you need to push the needle down and be able to rotate the knob which is going to vary the distance between the blades.  You need to put that needle back into a step and these steps have linear incremental steps. 

For example, in a round knob, its three hundred sixty degrees and it might have say ten incremental steps around that diameter.  You should be moving the knob where you get that step and that be able to put that needle so it won’t move from that step selection.  This is probably the most accurate way in selecting the same grind size. 

In a step less grind selection, it’s like a bolt and a nut where you keep turning the knot and you can twist it clockwise or anti clockwise.  So for example, if you twist it clockwise, it’s going to get finer.  If you twist it anti clockwise, it’s going to get coarser.  There’s a system in place where it’s going to keep it in that place.  It won’t move but the thing is, it gives you finer adjustments so you can fine tune that to very, very small increments.  But the problem is, for example to get this exactly the same size, if you change the selection, to get it back to the exact same size, it’s very hard.  Once you’ve adjusted it, it stays there. 

There are positives and negatives about both systems.  A step selection is more accurate in getting the same grind size but it has a very, it has steps, limited steps that you can take to get to a grind size.  If you take the knob to number five, it might be too fine.  So you need to go between five and six but because it’s a step, you can’t fine tune it.  So you’re going to have it on five or you’re going to have it on six.

In a step less stall, you can fine tune it, it have markings on it.  So if you take it to number five, if you need to get a little bit finer, you can actually move very minute steps.  You can move it as much as you want.  It doesn’t have any steps so you can move it as little as possible or as much as possible.  They are the features you need to have on a coffee grinder. 

I want to give you some tips and tricks about buying a coffee grinder or selecting a coffee grinder.  This is very important because there’s so many different models and different power consumption and power supplies that you can get for a coffee grinder.  In a domestic situation, in Australia, your general purpose power points only have the capacity of then amps.  But you got to take in consideration the houses you might have ten power points running off the one fuse at your switch board.   

If you put a coffee grinder that is ten amps and you have a twenty amps supply and then you have a  kettle that draws ten amps, and then you have a toaster on the same line, you’re going to trip your power supply.  You might need to get an electrician to run you a separate power line from your switch board to plug in your coffee grinder.  That can cost you a lot of money. 

In a domestic situation, you buy commercial stall coffee grinders, you have to take that in consideration.  You might need a separate supply.  In a commercial use, when you’re designing your café, you need to have a separate line for your coffee machine, a separate line for your coffee grinder.  The power ready on coffee grinders is quite high and having a separate line for your coffee grinder is going to eliminate problems in the future.  If you do decide to upgrade your coffee grinder, it’s there.  If you have your coffee grinder and it’s been used constantly and you have other appliances on the same line, it’s going to trip the power board and you’re going to keep having problems.  You can’t keep running back to the switch board, switching it on.  It’s going to be very annoying.

You got to take that into consideration when buying a new grinder, you need to buy a coffee grinder that has a very similar power consumption or when you’re designing a new place, to take that into consideration and have separate line.  In commercial use, the power consumption of coffee grinders can vary between say, seven amps, ten amps, fifteen amps.  So that’s why you need to have a separate supply.  The other thing is, the power supply needed for a coffee grinded.

There are two types of power supply, you can get a single phased or a free phased.  Eighty percent of your grinders will be single phased, your free phased supply coffee grinders will be for a very high capacity commercial used situations.  You won’t be using that at home and you’d particularly have been looking at single phased for domestic use.

In commercial use, it is single phased but again, if you’re using hard volume, you’d need to go to free phased.  The reason for that is the motor capacity is more efficient in grinding a greater volume, to get you the speed to be able to grind more coffee at a very short time so you need a big motor with big blades to grind high volume and having a big motor is not going to introduce heat into your coffee grinder.  That’s why you would need a free phased supply for that particular coffee grinder.

If you’re replacing a coffee grinder, you need to match power, rating of your current coffee grinder and look for something very similar to that.  If you are not sure, just get an electrician to come out and ask them to give your quote and then you can find out if it’s suitable or not suitable. 

Another important thing is, how many coffee grinders would you need?  I would say you would need one coffee grinder for each brew method?  And each coffee bean that you’re going to use.  So for example, you have your main espresso blended coffee, you’ll need a grinder for that, if you’re going to serve decaffeinated coffee, you need a separate grinder for that.  If you’re going to supply drip or your French presto coffee, you need a separate grinder for that.  You can’t be changing all the time, different brew methods and you have different coffee beans, you need to have a separate grinder. 

Each coffee bean has its own grind selection, each brew method has it’s particular grind coarseness so, you can’t swap and change.  If you have one grinder and a customer needs decaf, you got to dump all the coffee beans out to be able to grind your decaf coffee.  It’s going to take you a very long time and it’s going to be very annoying. 

I’ve seen some people pre grind the coffee and have it containers.  It’s not very good, if you’re serving a single origin coffee, besides your main blend, then, you need to have a different grinder for that coffee bean because it will require a different grind selection again. It depends on your usage, your main blend will probably be used the most and have high volumes required. 

So you need to have the best grinder for that.  If you’re serving single origin coffee, it’s probably not as common as your main blend.  So you can get away with something a little bit cheaper than need to spend thousands of dollars for your single origin.

You probably can get one or two steps down from your main grinder, for your coarse for grinding coarse coffee grounds, you can get away with something more cheaper, again, so you can get something that’s cheap, that’s going to grind you coarse coffee that’s consistent so you can serve your filtered coffee or your French press .  That’s something to take into consideration.

Another thing I would take into consideration is, depending where you live or where your café is situated.  Contact your service people that service your machines.  Ask them what is the most common coffee grinder that they have parts for, contact three or four service people because if something does go wrong with your coffee grinder, you want to have the parts available to you quickly.

You can’t afford to have a coffee grinder down. You’re losing money. It’s quite important to have a coffee grinder that is very common with the service people that service your area. So ask them, what is the most common coffee grinder that they service. Find out the brand and then source out the model and then ask them again if they have parts available for that particular model.

By now, it’s expensive to buy coffee grinders. It can get expensive. If you take the information I’ve given you, you can make a decision. How much you need to spend for your particular use. Ideally you want to spend as much as you can or you mind coffee that you serve. So if that’s your blended coffee, buy the best that you can afford and take those features I discussed earlier for your main blend.

For your single origin, your decaf, just get something that has those features but in a cheaper version of it depends on your volumes. You might serve high volume of decafs for, so you need to have a good quality coffee grinder, so you’ll avoid those variations and introducing those new variations to your final cup. An action step to take is, to clean your grinder, remove the coffee beans, store your coffee in an air tight container at the end of the day. 

Clean the blades on your coffee grinder. One more tip before I forget, when you are adjusting your coffee grinder, take this into account because sometimes, you can be chasing a tail. When you’re selecting the grinder for your brew method, you got to take into consideration when you grind the coffee, there’s a chamber between where the blades are, to where the actual coffee gets stomped.

Whether it gets stomped into a container or into your group handle. That little chamber is going to hold some coffee.

Now when you’re making adjustment either you go more coarse or more finer. When you grind the coffee again, you’re going to have the existing selection that you had previously in the chamber and then you can have the new grind selection coming through and it’s going to push out the old grind.

When it gets pushed, it’s going to pushed up half of your old and half of your new grind, so you might have some of the finer or some of the coarser. It’s going to be mixed. What you should be doing is going to grind it for about 3-4 seconds and just throw that coffee grinder away, when you adjust your coffee grinder.

So if you need to make an adjustment on your coffee grinder, adjust it, grind for about 5 seconds and throw it away. Dump it.  Then grind your coffee, temper it and make your coffee.

If the coffee is still not coming out good, I would suggest it one more time just to be sure that it’s still don’t have that mixture of coffee. You repeat the process again with the same grind selection for the second time and see if it’s still not producing the correct brew, then, make your adjustment, grind it for five seconds, and dump that. Grind it again and after you dump it, grind it and put it on the machine. That’s going to eliminate headache so that’s one thing.

Another action steps, see how easy it is to remove a hopper, clean your blades, have to look at the ware on the blades and replace them. Go and buy new coffee blades and replacing is not hard. The screws that hold the blades you can unscrew them and put the new blades on. If there’s residue in that chamber, clean all the residue because that’s going to taint the coffee taste. Have a look at what particular blade you have is it a flat, is it a burst off or is it a blades off. There are some extra steps to take and clean your machine.

If you don’t have time, you’re busy, have one of your employees stay back for another ten minutes. Allocate someone to clean your machine.

It’s not hard to do. Just show them once or twice and they’ll be able to repeat that process every time. I hope that’s a help with you selecting a coffee grinder. It’s a help you with your existing coffee grinder and its help you with some tips grinding and what to look out for. It’s a lot effort for the process.
