Grinding of coffee beans
There are three kinds of grinding methods for coffee beans: "grinding", "grinding" and "mortar grinding".
1. Grinding:
Two rotating parts are used to squeeze and crush coffee beans. The grinding parts can be disc-shaped or conical. Conical machines are less noisy and less likely to block. The coffee powder produced by the grinding method is more uniform and the taste is more consistent when cooking. The design of the conical grinding disc reduces the required speed, which is generally less than 500 revolutions per minute. The slower the grinding speed, the less heat generated by friction, so the aroma of coffee is not easy to lose. By adjusting the grinding parameters, the cone grinder can be used for the preparation of different kinds of coffee. A better machine can grind the ultra-fine powder needed for Turkish coffee. Disc grinders generally have higher rotational speed and generate more heat, but they have a wide range of functions, economical and practical, and are suitable for the preparation of most household coffee.
two。 Polish:
Most modern machines actually cut coffee beans into pieces at a speed of 20, 000 to 30, 000 revolutions per minute (some people simply use beaters). The consumption of this kind of blade grinder is longer, but the accumulated heat in the grinding and the uneven size of the coffee chips make it difficult to produce high-quality drinks. In theory, this kind of grinder can only be used for drip coffee pots. The dust they produce can clog the filters in espresso and French press machines.
3. Molar mill:
If you can't find good grinding equipment, all you can do is to use a pestle and a mortar to slowly enjoy the fun of labor.
