The working principle of American coffee machine mainly includes water heating, extracting coffee and dropping coffee. First, the user needs to pour an appropriate amount of water into the water tank of the coffee machine, and then the machine will automatically heat the water to a certain temperature. The heated hot water is pumped into the filter basket, soaked with the filter paper filled with coffee powder, and the flavor of the coffee is extracted into the water by high pressure extraction. The liquid, which has become American coffee, is then dripped into the coffee pot through a pipe below the filter basket. Throughout the process, water temperature, pressure and extraction time are key factors that affect the taste of coffee.
American coffee machine uses high temperature water and certain pressure to extract the essence of coffee beans into the water to produce American coffee with rich aroma and mellow taste. In the whole production process, it is very important to ensure that the temperature of the water is stable, the extraction time is reasonable, and the extraction pressure is suitable. Through the reasonable control of these parameters, making the production of American coffee more rich taste, rich flavor. This working principle of the American coffee machine makes it easy to enjoy coffee shop-level delicious coffee at home.
