Grinding tool-- make coffee beans powder in detail

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.

More and more coffee players are fond of roasting their own coffee beans, because usually after the coffee beans are roasted, they can only keep their freshness for 1 to 7 days, and then they will begin to stale, leaving only bitterness and no mellow taste. Therefore, self-baking can ensure the freshness of coffee beans. They describe this feeling as frying a plate of fresh vegetables or steaming a fresh fish, which tastes better than the dishes at a banquet and can add a lot of interest.

The traditional roaster is drum-type, which has the characteristics of stewing, which will make the coffee beans more mature and full-bodied. The household drum roaster can bake half a pound of coffee beans at a time, and the baking time (including cooling and producing beans) takes about 210.25 minutes. If you want to roast deeply, you only need to increase the time. When in use, just put in the raw beans, set the baking degree, press the start button, from baking to cooling, the roaster can do it automatically, and all you have to do is slowly enjoy the coffee beans jumping up and down happily in the roaster.
