I. Classification of coffee machines
Coffee machines play a decisive role in brewing fragrant and delicious coffee. There are many brands of coffee machines in the market. Generally speaking, coffee machines can be divided into automatic coffee machines and semi-automatic coffee machines.
1, fully automatic coffee machine
Automatic coffee machine is a kind of automatic coffee making machine which avoids the operation of hands. This kind of coffee machine can not only grind, fill and make coffee, but also add hot milk to make milk coffee. Because with the development of the coffee machine market, the so-called "automatic coffee machine" is no longer limited to the coffee machine that can finish grinding, filling powder, pressing powder, filtering and cooking and cleaning with one button. It has developed many new functions according to the needs of users, such as adjusting the thickness of grinding beans, making ESPRESSO and CAPPUCINNO coffee, etc. The structure of automatic coffee machine is complicated, but it is convenient, fast, consistent in quality, high in efficiency, and there are many kinds, but it needs good maintenance and high in maintenance cost.
2, semi-automatic coffee machine
Semi-automatic coffee machine is mainly produced in Italy, which has simple structure and easy maintenance. According to the correct use method, high-quality Italian coffee can be made. Compared with the automatic coffee machine, the semi-automatic coffee machine is a professional coffee machine. Because the semi-automatic coffee machine can't grind beans, it can only use coffee powder, and the operator needs to fill and press the powder himself, which involves the coffee making process, so it is called a real professional coffee machine. Its characteristics are: constant water temperature; Pump pressure is stable; Steam is constant pressure and dry, easy to operate, etc.
3, drip coffee machine
Drip coffee machine is a classic drip filter. Simple, efficient and reliable, suitable for public use. The working principle of the drip coffee machine is also relatively simple. It contains a funnel for placing filter paper and coffee powder, and it is essential to have a device for filtering coffee. If you choose to use the drip coffee machine, you must buy filter paper. A V-shaped funnel on the top and a removable coffee pot on the bottom are the classic styles of drip coffee machines.
4, high pressure steam coffee machine
High-pressure steam coffee machine is a combination of pump pressure and steam type. The drip coffee maker mentioned above uses one atmospheric pressure when brewing coffee, that is, it is brewed under normal pressure, while the pump coffee maker uses the principle of pressure. When brewing coffee, the pressure of water is greater than one atmospheric pressure, generally 5- 19 atmospheric pressure, and the coffee essence is quickly extracted. The brewed coffee is fragrant and has a layer of grease foam.
