The pump pressure of a typical coffee machine is usually 9 Pa.
Italian coffee machines typically use boilers to generate hot water, which is then pressurized to produce steam, fumigate coffee beans, and extract coffee. Compared to American coffee machines, this type of coffee machine produces coffee with a strong flavor, but with oil on the surface, and is more expensive because the coffee machine has an electronic control switch inside and an air pump.
The fully automatic coffee machine has a comprehensive protection system and is very convenient to use, which is superior to traditional coffee machines in terms of convenience. But its structure is relatively complex and requires good maintenance, which incurs high maintenance costs. Before using an electric coffee pot for the first time, two pots of boiling water should be boiled to remove any unpleasant odors. After use, dry it with a dry cloth and place it in a place that is not easily accessible to children. Do not invert it or press it with heavy objects.
