A brief History of Coffee Machine semi-automatic Coffee Machine traditional Italian coffee machine

Coffee machine people apply electronic technology to the coffee machine to realize the automatic control of the whole process of brewing coffee, such as grinding, pressing, loading, brewing, removing residue and so on, creating the coffee machine.

Before the second World War, although it avoided the disadvantage of using steam as a source of pressure to burn the coffee powder easily, because the pressure is to transmit the strength of the arm through the piston to push the hot water, not only a strong arm is needed, and the pressure is not easy to stabilize.

World War II stopped Cremonesi and Gaggia from improving the coffee machine. When Cremonesi died during the war, he left the patent for the coffee maker to his widow, Rosetta Scorza. We don't know whether Rosetta Scorza told Gaggia about the design patent, or whether Gaggia's design came entirely from its own invention. In 1947, Gaggia improved the original piston principle, and the force of the piston was controlled by a spring. As long as the operator presses the rod, the spring will be compressed and hot water will be injected into the space between the piston and the coffee powder. When the spring on the piston expands, press the piston down, the hot water will flow to the coffee place, and the rod will return to its original position.

In 1948, Gaggia applied this principle to complete his coffee machine, because he pushed hot water into a denser coffee powder and the pressure was greater and more stable than ever before, resulting in a layer of Krima on the coffee, which appeared for the first time in history. Since then, Klima has become the symbol of Italian coffee, and like Turkish coffee in the past, Klima is also the standard to judge whether coffee is good or bad. Gaggia's coffee machine also makes the brewing process more dramatic, with the arm operating the crossbar and the crossbar slowly returning to its original position, which has become a routine at many Espresso bars.

The household La Pavoni still maintains the tradition of Signore Cremonesi and does not add a spring to the piston, but some coffee machines on the market that are very similar to La Pavoni, such as the Elektra (Family series), add springs to make the pressure stronger and more stable. The method of discrimination is very simple, as long as you gently press the crossbar to see if there is any reaction force of the spring.

Next, the editor will focus on introducing the semi-automatic coffee machine.

Semi-automatic coffee machine, commonly known as handle machine, is a traditional Italian coffee machine. This kind of machine grinds, presses, loads, brews and removes the residue manually according to manual operation. These machines include small household machines with single faucets, large commercial machines with double faucets and three faucets, etc., and 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. Its main features are: simple machine structure, reliable work, easy maintenance, according to the correct method of use can produce high-quality Italian coffee. The drawback of this machine is also that operators have to be strictly trained to make high-quality coffee with this machine, and good baristas can provide customers with customized coffee.

But if you can make a delicious cup of coffee by hand, it is indeed a kind of spiritual enjoyment.
