Commercial coffee machines Coffee powder containers for extracting coffee-pump coffee machines Coffee powder fineness
The grinding disc of any bean grinder generates heat during the grinding process, and the coffee powder is heated to accelerate the oxidation process, accelerate the aroma volatilization, and cause the brewed coffee flavor to be weakened. The calorific value of the cutter head depends on many factors such as the size of the grinding disc, the material, the structure of the cutter, the fineness of the grinding, the speed of the motor, the hardness of the coffee beans and so on.

American coffee machine: atmospheric extraction
Usually divided into two layers, the upper layer is a funnel-shaped container with filter paper or metal filter, and the lower layer is a glass or ceramic coffee pot. American coffee machines also make hot water flow into the coffee pot below through coffee powder to extract coffee, but the difference is that hot water is atmospheric pressure. In addition to cooking coffee, you can also make tea.
American coffee machine, no pressure, only black coffee, can not make other fancy coffee. Espresso coffee machine, with a certain pressure, can use pressure to make ESPRESSO coffee with a fairly thick coffee oil. Some regular espresso, can be made with milk, latte, foam, cappuccino, and other fancy coffee; price: American coffee is generally less than 1,000 yuan. Italian coffee machines, prices range from a few hundred to more than 100,000 yuan
In general, the finer the grinding, the faster the grinding machine, the stronger the static electricity generated; the internal material is plastic, the lower powder mouth does not use the static electricity reduction design of the grinding machine, the static electricity generated is stronger; the fat rich, roasting degree of coffee beans grinding, the static electricity generated is stronger. Italian bean mill in the grinding often appear fine powder into a group, affecting the density of the powder after the cloth, resulting in uneven extraction; and single bean mill powder outlet magnet is through electrostatic adsorption silver skin and fine powder, to help reduce excessive extraction taste and miscellaneous taste
