Grinding adjustment device, coffee machine and flow adjustment method based on flow

Abstract

The invention discloses a flow-based grinding adjustment device, a coffee machine and a flow adjustment method. The flow-based grinding adjustment device includes: a grinding unit, the grinding unit has a particle size adjustment mechanism, and the particle size adjustment mechanism is used to adjust the grinding. The thickness of the coffee powder; a flow sensor, the flow sensor is connected to the coffee liquid, and is used to detect the flow data of the coffee liquid flowing out; a control unit, the control unit is electrically connected with the flow sensor, the solenoid valve and the particle size adjustment mechanism, wherein the control The unit is used to open and close the electromagnetic valve within a preset time period, collect the flow data of the coffee liquid detected by the flow sensor, and control the particle size adjustment mechanism to adjust the thickness of the coffee powder. The invention can accurately obtain the objective difference between the current coffee liquid and the predetermined flow rate, so that the thickness of the coffee powder can be precisely controlled and adjusted. Compared with subjective experience, it has more accurate and uniform flow regulation.

Description

technical field [0001] The invention relates to a flow-based grinding regulating device, a coffee machine and a flow regulating method. Background technique [0002] At present, the coffee made by mainstream coffee machines can only meet the tastes of some consumers, but cannot meet the individual requirements of users for the taste of light bitter and light sour. The success of coffee liquid extraction is significantly related to the type, tissue structure, particle size and shape distribution of coffee beans. [0003] The coffee machines currently on the market need to manually adjust the distance between the grinder cutters according to the actual extraction situation before use, to determine the size and shape distribution of the coffee powder particles, so as to extract the coffee liquid that meets the requirements. The method of adjusting the distance between the grinder burrs is mainly to adjust the grinder burrs by manually turning the adjustment knob, thereby adjus...
