The system comprises a water pump, a one-way valve, an electromagnetic proportional valve, a three-way electromagnetic valve, a control device, a pressure setting device and a brewing branch circuit, wherein the delivery-in end of the water pump communicates with a water source, the delivery-out end of the water pump communicates with the one-way valve, the delivery-out end of the one-way valve communicates with the electromagnetic proportional valve, the communicating delivery-out end of the electromagnetic proportional valve communicates with a water drain outlet, the brewing branch circuit comprises a pressure detecting device, a heating device and a brewing device, the delivery-out end of the three-wayelectromagnetic valve communicates with a brewing device and the water drain outlet, the delivery-out end of the pressure setting device is connected with a control device, and the delivery-out end ofthe control device is connected with the water pump, the electromagnetic proportional valve and the three-way electromagnetic valve. The invention relates to the technical field of coffee makers. Forthe brewing system with variable pressure for the coffee maker, the purpose of adjusting the coffee-brewing pressure value in real time and stabilizing the pressure at the set value is achieved.
Description
technical field [0001] The invention relates to the technical field of coffee machines, in particular to a pressure-variable coffee brewing system. Background technique [0002] At present, when the coffee machines on the market are making coffee beverages, there will be a high pressure in the brewer cavity, and the quantity and thickness of coffee powder in the cavity are one of the variables that affect the pressure, and the size of the pressure determines the coffee. key variables of quality. However, the existing coffee machine can only manually correct the pressure required for brewing before making coffee beverages, and when the type of coffee beans used changes or the thickness of the coffee powder changes, the pressure of the coffee machine during brewing cannot be adjusted in real time. This affects the actual brewing pressure, resulting in a lower quality of extracted coffee. [0003] When coffee beans from different origins are brewed, different multi-stage pres...
