Commercial Coffee Grinder Varieties 2021

A commercial coffee grinder is a professional-grade kitchen device used to grind coffee beans. It is different from a household grinder in that it is larger in size and often more powerful. But do not be mistaken: a commercial grinder can also be used at home. Whether we are looking for a used commercial coffee grinder, a vintage yet functional model, or a coffee maker with grinder, it pays to know the different types we are going to encounter. Let us go through each one of these.


Blade Grinders

This type of coffee grinder makes use of metal blades that move at high speeds to “grind” coffee beans. Notice the quotation marks on the word “grind”: this is due to the fact that a blade grinder actually cuts up the beans and does not grind them in the real sense of the word. Basically, what we have here is a form of food processor that chops up the beans to our desired consistency, and the longer it runs, the finer the grounds we are going to get. Blade grinders are cheap – you can buy one between 30 and 50 dollars – and some models are great for travel because they are small and portable. However, the grounds they churn out are never consistent in texture so they are not advisable for espresso.

Burr Grinders

Burr coffee grinders feature two metal plates – one moving and one stationary – that grind beans by rubbing together. The fineness of the grounds is determined by the space between the two plates – which is also where the coffee beans are positioned. Any burr coffee grinder commercial – provided that it is of high quality such as the Bunn commercial coffee grinder – will produce grounds of uniform size and texture. There are two types of burr grinders: flat and conical.

Flat Burr Coffee Grinders

Flat burr grinders are typically used to grind coffee beans for espresso. These are called such because their grinding mechanism consists of two flat, identical plates made of steel or ceramic that are placed one on top of the other. A flat burr coffee grinder is more expensive than a conical burr grinder because the plates are often mounted on aluminum or brass to secure them.

Conical Burr Coffee Grinders

Flat and conical burr grinders employ the same method in grinding coffee beans. The difference is that the burrs in this type are not identical – one takes the form of an outer ring, and the other, an inner cone. Since these need not be mounted, they are cheaper to build and consequently, to sell, compared to flat burr grinders. The grinding process also takes longer, but this means the aroma of the beans being ground is kept intact. They are used to grind beans for French Press, percolator, and drip coffee.

Manual Grinders

Commercial coffee grinder reviews rarely recommend manual models simply because these need to be hand cranked. Grinders of this type rely on our arm muscle power and do not need any electrical power source to work. While manual grinders do take a lot of time and effort to operate, the grounds they produce are better and more consistent than that produced by blade grinders.
