Be sure to use special appliances, which are called "bean grinder", both hand-operated and electric; The special bean grinder grinds coffee beans through two internal grinding discs, which is different from other equipment. The advantages are that the ground powder particles are uniform, the grinding process can be completed without too much extrusion pressure, and the fragrance will not be scattered too much.

The processing steps of coffee beans are simply divided into the following steps:

1\ Pick coffee fruit

2\ Remove pulp by dry cleaning or water washing, leaving stones.

3\ Naturally air-dried or sun-dried stones are coffee beans.

The grinding tool for coffee beans is a bean grinder. Soymilk machine can be divided into three types:

● Household manual rotating bean grinder. Suitable for leisure people with small demand, big particles and killing time. )

● Household electric bean grinder. Can grind coffee powder of various particle sizes, and can grind 6 people at a time. )

● Professional electric bean grinder. For commercial purposes, more or less than one pound of coffee powder can be ground at a time. )

Pay attention to the following two points when grinding coffee beans:

● Reduce grinding heat. (The heat of grinding will cause the coffee aroma to overflow prematurely. )

● Uniform particle size. (Uneven particle size will lead to out-of-control brewing time)

Therefore, if you use a family-style manual soymilk machine, you should turn it gently and try not to generate friction heat. In a word, if the quality, quantity, time and convenience of grinding beans are considered comprehensively, using household electric bean grinder will be the best choice.
