Is the degree of grinding uniform?

Known conditions: the finer the coffee powder grinding particles, the larger the surface area of contact with water; the thicker, the smaller the surface area of contact with water.

Problem-solving process: when the extraction time, temperature, water, method and other factors remain unchanged, due to the larger contact area, the fine powder extraction rate will be higher and the coarse powder extraction rate will be lower.

It is concluded that in the same extraction process, if there is a great difference in grinding thickness of coffee powder, the coffee produced may have two frustrating conditions of under-extraction and over-extraction at the same time. If the extraction state of each coffee powder is different, the taste will be too complex.

The core of determining the uniform grinding lies in whether the concentricity of the grinding center of the bean mill is good enough. Coffee powder is obtained by staggered grinding of the internal and external grinding center. If the fixed structure is not precise enough, the distance between the internal and external grinding center is always changing during rotation, and the grinding powder will be coarse and fine.

Fine powder is not easy to have too much.

No matter what kind of bean grinder is used, very fine powder will be produced, which is determined by the physical structure of the coffee bean itself. It's just that different bean grinders produce different amounts of fine powder, but there are usually more than 10% of the fine powder.

So fine powder, what happens when it's too much? it's over-extracted! What will happen to excessive extraction? it will be very bitter!

Therefore, the quality of a hand mill is directly reflected in whether the degree of grinding is uniform and the rate of fine powder.

Comfortable and labor-saving to use

Compared with electric power, the hand mill is not restricted by the site, so it is indeed a good choice, but it is relatively laborious to use, especially for soft girls. So when choosing a hand mill, you need to consider whether it is comfortable to use and whether it allows you to grind coffee beans easily.

The thickness regulating valve is stupid and naive.

According to different baking degree and extraction tools, the grinding degree is also different. Oh, some hand-ground thickness control valves are easy to run the scale during grinding, which will cause uneven grinding degree. When choosing a hand-grinded coffee machine, you must choose it according to your actual needs.
