What is the thickness of the bean grinder?-how to adjust the thickness of the bean grinder

The bean chopper not only can not evenly treat coffee beans into coffee powder, but also the heat generated in this process aggravates the rapid loss of oxidation flavor of coffee beans.

The first principle of fine coffee extraction: uniform extraction. The coffee powder of the chopping machine is coarse and fine, which leads to excessive or insufficient extraction of coffee, excessive scorching and bitter taste, and insufficient sour and astringent hemp.

What are the types of bean grinders?

According to the coffee extraction method, it is divided into: single coffee grinder and Italian coffee grinder.

According to the structure of the grinding plate can be divided into ghost teeth, flat knife, cone knife.

According to the mode of work, it can be divided into manual manpower and electric power.

My personal advice is to buy the best bean grinder that you can afford.

Choose fresh coffee beans. When buying, pay attention to whether the color of the beans and the size of the particles are the same. Good coffee beans are shiny and have a strong aroma without being mixed with peculiar smell. No matter what kind of coffee beans, freshness is an important factor affecting the quality. When shopping, grab one or two coffee beans in your mouth and chew them with a crisp sound (indicating that the coffee is not damp) and the fragrance of the teeth and cheeks is the top grade, but it is best to squeeze it with your hands to feel whether it is solid, rather than buying crispy coffee. If the coffee bean has lost its flavor or smells stale, it means that the coffee bean is no longer fresh

The reason why the bean grinder is important is that it is the most important processing link before coffee is extracted. Here we briefly share with you the most important elements in the whole coffee chain: 1, coffee tree, it is the most important element in the plantation; 2, the processing process of coffee, it is the most important link before coffee comes out of the plantation. 3. Roaster, which is the key equipment to turn raw coffee beans without coffee flavor into roasted coffee with rich flavor; 4. Bean grinder, which is the starting point of roasting coffee beans on the bar; 5, is the extraction equipment. From this, the importance of bean grinder can be seen.

So what is a good bean grinder? Some knowledgeable friends will say: grind even bean grinder. In fact, a completely uniform coffee grinding does not exist. At present, the coffee powder produced by any coffee grinder is composed of coarse powder, medium-fine powder, fine powder and very fine powder. These coffee powders of different particle sizes play different roles in the process of coffee extraction, some are used to form alcohol thickness, and some are used to show flavor. So even if there is a completely uniform bean grinder, the flavor of the coffee is very mediocre. If you have the opportunity to use different mesh sieves, the ground coffee powder will be sifted and then made, and the effect will be clear at a glance.
