Introduction to the method and price of the brand ranking of automatic Italian coffee machine

Desiderio Pavoni obtained a design patent for Bezzera in 1903, and he has been making the coffee machine since 1905. After that, Teresio Arduino began to produce similar coffee machines, and other producers followed suit. In the 1920s, coffee shops in Italy could see signs of this kind of coffee machine. But the Italians are obviously not satisfied with the results of the steam pressure coffee machine. The pressure should be increased by steam, but increasing the heat may burn the coffee powder during cooking, losing the aromatic oil hidden in the coffee powder and making it more refined.

Take out the doubly bitter coffee. Therefore, some people think: can it be directly pressurized on the hot water instead of boiling the water with steam as the pressure?

During the two world wars, people used the natural pressure of water from the faucet to increase the pressure of brewing coffee. The coffee machine uses electricity to quickly heat a small pot of water to the boiling temperature, each pot of water to make a cup of coffee, each pot connected to the faucet. As long as the operator gently press the pole on the small pot, the pressure of the faucet will push the hot water in the small pot to the coffee powder. According to the difference of water pressure in different regions, generally speaking, the pressure generated by this coffee machine is greater than the 1.5 atmospheric pressure produced by the steam pressure coffee machine. The height of this coffee machine is not too different from that of the steam pressure coffee machine, but the overall size is smaller. The appearance is more in line with the popular trend of the late 1920s and 1930s, replacing the arc of the steam pressure coffee machine with straight lines and geometric lines.

Another way to generate more pressure than 1.5 atmospheres is to use compressed air. For example, a home coffee machine in Milanes collector Ambrogio Fumagalli uses an air pump to pressurize hot water for brewing coffee (during World War II). In 1938, Francesco IIIy made the llletta' Coffee Machine, a large commercial coffee machine based on the principle of compressed air. When the crossbar on the coffee machine was lifted before World War II, water was injected into the space occupied by the piston and pressed down, and the pressure on the piston injected water evenly into the coffee powder in the filter. this means that hot water can brew coffee before it boils without scalding the coffee powder. At the same time, Achille Gaggia, the owner of a cafe in Milan, used a similar method to brew coffee. This method is gradually adopted by other coffee machine manufacturers, so this new coffee machine is also gradually replacing the steam pressure coffee machine. Today, the application of this principle can still be seen on household machines, the La Pavoni.

At the same time, this kind of machines include small single-tap household machines, double faucets, three-leading large commercial machines, and so on. The newer machines are also equipped with electronic water control, which can accurately and automatically control the amount of coffee brewing. This kind of machine is mainly produced in Italy and is very popular in Italy.

The main difference between the fully automatic coffee machine and the semi-automatic coffee machine is what the author has mentioned above. At the same time, the selection of the coffee machine can be considered according to its own actual use. If there is any incomplete discussion, please correct and add.

In the process of making coffee, the semi-automatic coffee machine needs to be manually involved in grinding, pressing, brewing and cleaning of the residue. at the same time, the semi-automatic coffee machine has another common name: the machine is simple in structure and easy to maintain at the same time. High-quality Italian coffee can be made according to the correct method of use. The disadvantage of this kind of machine is that operators have to be strictly trained to make high-quality coffee with this machine, and it is not easy to maintain the consistency of coffee quality. In addition, the efficiency of this kind of machine is relatively low.
