Introduction of troubleshooting steps in c5 cleaning process manual of Yuri coffee machine
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-La Pavoni.

Two. if you choose an inappropriate pill, it will cause damage to the coffee machine and leave residual impurities in the internal pipe of the coffee machine, so please buy a professional descaling tablet for cleaning the Yuri coffee machine.
Three. If the descaling process is stopped, it will cause damage to the coffee machine, so once you start the descaling process, please do not stop halfway.
Four. if the descaling tablet or liquid touches the surface of the skin and causes minor damage, rinse immediately with clean water

Why coffee beans at high altitude are good-description of the flavor of coffee beans at low altitude
Why coffee beans at high altitude are good-the flavor of coffee beans at low altitude describes the lower the temperature, causing coffee to grow more slowly at higher elevations, and because the growing period is longer, coffee trees absorb more salt from the soil. the fuller and bigger the coffee fruit, the harder the beans, and the taste is naturally richer and sweeter. In addition, in areas with low temperatures, the leaves of coffee trees
