Manual bean grinder calibration-requirements for the thickness of hand-brewed coffee powder

The bean chopper not only can not evenly treat coffee beans into coffee powder, but also the heat generated in this process aggravates the rapid loss of oxidation flavor of coffee beans.

The first principle of fine coffee extraction: uniform extraction. The coffee powder of the chopping machine is coarse and fine, which leads to excessive or insufficient extraction of coffee, which is very bitter and bitter. What are the types of bean grinder that is sour and astringent?

According to the coffee extraction method, it is divided into: single coffee grinder and Italian coffee grinder.

According to the structure of the grinding plate can be divided into ghost teeth, flat knife, cone knife.

According to the mode of work, it can be divided into manual manpower and electric power.

My personal advice is to buy the best bean grinder that you can afford!

1. Adjust the thickness. Unscrew the screw from the top, open the handle, put the mark scale bar in place, and reinstall the handle and screw. This needs to be debugged many times, because there is no scale on it, so it can be marked by affixing it at will.

2. Put the coffee beans on the grinding plate

3. Shake the handle with uniform speed and force

4. Take the coffee powder out of the drawer.

Special attention is paid to: 1. Different grinding speeds affect the quality of coffee powder produced.

If the coffee powder is ground too slowly, the coffee powder will lose more flavor if it comes into contact with the air for too long; if it is ground too fast, the high temperature will volatilize more coffee aroma substances. The Doctrine of the mean, there must be moderation

Blade is another common coffee grinder, though not the best, but the most common. This type of grinder is designed to grind well, but blade friction may lead to the burning of some coffee beans. In addition, this approach does not provide the best consistency.

Another type is the disc grinder. It is also divided into two different types, namely, flat wheels and cones. Cones are considered to be the best choice to buy. The speed of the disc grinder is slower than that of the blade. The ground coffee beans are fed into a hopper and brewed into coffee. This method can avoid the burning of coffee beans and ensure consistency. But the only drawback of this bean grinder is that it needs more cleaning, which may take some time. But if you want delicious coffee, this is the best coffee grinder you can buy.
