Introduction to the video of graphic operation of semi-automatic 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. It should be possible to increase the pressure through the steam, but increasing the heat may cause the coffee powder to burn during cooking, losing the aromatic oil hidden in the coffee powder. Another way to produce more pressure than 1.5 atmospheric pressure 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-La Pavoni.

The first step: first choose coffee beans if you have coffee powder, you can use it better. If you choose coffee beans, put them in the box of the grinder. If you want to grind the coffee powder finer, just rotate it counterclockwise. If you want to grind the coffee powder, you can rotate it by 2 to 3 clockwise.

The second step: grind the coffee beans into powder, and then put the coffee powder in the handle slot. Don't fill it too full. When the handle slot depth is about 2 prime 3, you start to flatten the coffee powder with the powder pressing tool. You are a little particular when pressing the powder. According to your personal preference, if you want to drink something strong, use a little more strength when pressing the powder. If you want to drink something light, use a little less power. At the same time, a cup of high-quality coffee also has a lot to do with the coffee machine, the author will not say any more about this point.

Step 3: after the coffee powder is pressed, you need to use the semi-automatic coffee machine now. before using the semi-automatic coffee machine, you have to plug in the power to turn on the coffee machine, and then take the pressed coffee powder and rotate it at a 45-degree angle to the right of the semi-automatic coffee machine to feel ok.

Step 4: coffee can be filled with cups. There are signs on the semi-automatic coffee machine that are divided into single cup, single cup and double cup, and double cup and half cup. If two people like to drink strong coffee, then choose the double cup and half cup button. Put the cup under the mouth of the coffee and press the button. There is no need for people to watch beside the semi-automatic coffee machine. The coffee will be closed automatically after the coffee flows. This is the operation process that the author is using semi-automatic coffee mechanism to make coffee.
