Description

Technical Field

[0001] The utility model relates to the technical field related to the pressurization of a coffee machine boiler, in particular to a multi-layer pressurization device for a multi-boiler coffee machine. Background Technique

[0002] A coffee machine is a general term for coffee brewing appliances, which is a machine that integrates the whole process of coffee brewing, such as grinding, tamping, loading, brewing, and removing residues. Brewing coffee has precise requirements for water temperature. If the water temperature is too high, the brewed coffee will be a bitter water with a burnt taste. If the water temperature is too low, the taste of coffee cannot be reflected. Therefore, the control of water temperature is very important. Ordinary coffee machines have a single boiler and a set of heaters to heat the water temperature for brewing coffee. Metal seamless pipes that penetrate the boiler horizontally or vertically are used for heat exchange, so as to achieve the purpose of heating the water temperature for brewing coffee. Because coffee has high requirements for the brewing water temperature, the water temperature changes greatly after the hot water comes out of the boiler in ordinary coffee machines. When brewing coffee continuously for a long time, the water temperature will drop rapidly, which is likely to affect the coffee flavor. In addition, single-boiler coffee machines can only perform a single task at a time and have a long heating time, and the control ability of temperature and water pressure is insufficient to meet the needs of different beverages. Content of the Utility Model
