Grinding tools to make coffee beans more meticulous

In order to blend with the water, coffee made the greatest sacrifice-to pieces. Before brewing coffee, the beans must be ground into fine grains to increase the contact area between water and coffee in order to extract the delicacy.

In fact, the bean grinder is more important than the coffee machine, and players suggest choosing a "sawtooth grinder" because it can grind a uniform coffee powder quickly and steadily.

The operation method of the sawtooth bean grinder is very simple, generally speaking, it will have two setting functions, one is to set the grinding degree, the other is to set the grinding time. The degree of grinding is mostly expressed in Arabic numerals, and the smaller the number is, the finer the grinding is.

On the top of the bean grinder is a funnel shaped box containing unground beans, and below is a drawer to hold the ground coffee powder.

When you choose to buy a bean grinder, you should pay attention to its power, usually between 70 watts and 150 watts, the higher the better, the higher the power, the faster the grinding speed, and the shorter time the coffee powder stays in the sawtooth, so it can grind the coffee powder at low temperature.
