The main structure of the espresso machine consists of a motor linked with two blades located opposite each other.

Professional Coffee Grinders – Usage And Care Instructions

Most coffee grinder blades are conical or flat.

The cone will require less rpm than a flat plate because the beans go down by gravity. The flat disc form must use a more significant machine rpm to generate centrifugal force to push the coffee out and grind the coffee beans into a powder.

The capacity of the coffee grinder also depends on the blade. Coffee grinders with conical blades are generally more efficient because less effort is required, and the temperature of the edges also increases less.

Regardless of the type of blade used, the fineness of the coffee powder depends on the distance between the two edges. The farther the two blades are apart, the bigger (coarse) the coffee powder is and vice versa.

There are also coffee grinders on the market that operate on cutting beans. This type of blender has a blade similar to a blender. However, you cannot adjust the fineness of the coffee beans, so this grinder is for home use only.

As a professional coffee business consultant for many years, Helena Coffee gets a lot of questions. The following are typical questions regarding coffee grinders.

  1. What if the blender is overworked? Assuming the manufacturer recommends 600 cups of coffee/day, what if you go for 700 or 800 cups/day? If this is a spike over a couple of holidays, no problem. But if you are too crowded and the blender is always overloaded, you should invest in another blender. When overloaded, the blade will overheat and directly affect the quality of the espresso. Sometimes, the coffee grinder also stops working on its own because of overheating. And if at that time you have a lot of customers ordering coffee, it will be a disaster.
  2. Is it possible to put the large coffee powder in the grinder for a finer grind? Usually not possible. Because the coffee powder will seal the space between the two blades, the blade cannot move. If you accidentally put the coffee powder into the grinder, you should open the blade gap larger so that the coffee powder can fall. Otherwise, the motor tries to spin, but the propeller won’t turn, which could break the driveshaft or even burn the motor.
  3. Is it okay to have coffee with a bit of butter? When grinding butter coffee, the butter sticks to the blade, reducing friction between the beans and the coffee, so you may not be grinding as fast and as much as you would when grinding ground coffee. In addition, the butter will flood the blade, hindering the heat dissipation of the edge and partially reducing the life of the coffee grinder.
  4. Why is there a strange noise when grinding coffee? When you hear strange noises in your blender, your blender has encountered a foreign object, not coffee beans. You should stop and pull out the blade to check and remove the foreign body. Very dangerous when you continue to grind, foreign objects can chip the edge.
  5. Can a coffee grinder be used to grind rice, chili, pepper, grains, or other nuts? In theory, it’s entirely possible. But professional coffee grinders are designed by professionals to grind coffee beans, not other beans. And it’s also bad if your coffee has some horny chili left on it. It would help if you used a guillotine to grind spices like pepper, cloves, and other complex and small spices.
  6. What happens if I don’t clean the coffee grinder? Usually, the old coffee powder will still stick and directly affect the quality of the coffee cups. The older the coffee powder, the worse the cup of coffee. Sometimes, superfine coffee powder clings to the grinder causing the blade to jam. Therefore, you should have a periodic cleaning schedule to ensure the blender works stably.

Thus, Helena Coffee has introduced a few ideas and a few questions for you. It will help you choose the right coffee grinder for your needs and get a basic idea of ​​using the grinder.
