The work of grinding coffee beans has a great influence on the flavor of coffee, which is actually a very important process. This time we introduce the difference of coffee grinding teeth when grinding coffee beans.

Type of coffee mill

The equipment for grinding coffee is called "grinder" and there are manual and electric types. Although the names of the parts of crushed coffee beans are not uniform, they are roughly divided into three types: "cutting type", "grinding type" and "propeller type".

Surprisingly important! Mill's teeth.

The most important thing to choose the mill is the tooth profile of the mill. For those who insist on the taste of coffee, performance and clarity are very important. Manual, power regardless of functions, good features are a reasonable price, but sometimes you can buy features similar to those of manufacturers at a low price.

What is the tooth cutting of a coffee mill?

Tooth cutters are many types of electric mills used for commercial and household use. A pair of irregularly shaped teeth squeeze it in order to cut off the squeezed beans. The fineness can be adjusted by the distance between the fixed teeth and the rotating teeth.

Advantages and disadvantages of cutting type

The grain uniformity is good. Because the cut is clean, the extracted coffee is easy to show a clear taste and its taste is easy to express. As a disadvantage, the fine powder is easy to come out and the particle size is irregular, so it is not suitable for rough grinding the ground in the polar regions.

It also has the advantage of producing less friction heat, but it is more suitable for medium and fine grinding than rough grinding because it emits more fine powder than molars. This is a bit expensive coffee mill than Moore's formula.

What are coffee mill molars?

The molar formula is called a "grinder". A tooth is conical, fixed teeth and rotating teeth grind beans. The manual coffee grinder is an electric mill.

By adjusting the gap between the teeth, it can be adjusted from rough ground (wide gap) to fine gap (narrow gap). The material of metal mortar is common, but ceramics are recommended for those who use it for a long time.

Advantages and disadvantages of Moore expression

Although it does not produce too much fine powder compared with tooth cutting, friction heat is easy to occur. In order to prevent the flavor of coffee from being damaged by friction heat, the handle needs to be turned gently and slowly when using manual grinding.

Because the grinding eye is orderly, it is suitable for rough grinding, but compared with the cutting type, it is difficult to show the taste outline and taste.

The difference between grinding coffee molars and incisors

Even if a mouthful of ground coffee beans, due to the different tooth shape of the mill, the flavor of coffee will change greatly. Since the taste varies according to the particle size of the coffee powder, from the stage of grinding, try to stick to the shape of the teeth? Different tooth mills may make new discoveries in coffee fields.
