Food processor air pump control method for extraction

Abstract

The invention provides a food processing machine air pump control method for extraction, the food processing machine air pump control method is applied to food extraction processing, the food processing machine is mainly achieved by controlling intermittent work of an air pump, and the air pump control method comprises the following steps: an air inflation stage, the air pump is controlled by the control module to pump and pressurize the outer space between the extraction cavity and the cup body, and the downwards-pressed liquid forms circulating water and enters the inner space from the filter holes; in the intermittent stage, the air pump is controlled to stop pumping air, the air is guided out through the pressure relief module, the air pressure is recovered to be in a balanced state, and circulating water is guided to flow back from the inner space to the outer space under the action of self gravity; in the circulation process, the air pump is controlled to circulate in the inflation stage and the intermittent stage, and the extraction materials in the extraction cavity are extracted in a reciprocating mode through circulating water. According to the cold extraction device, cold extraction is achieved only through the one-way inflation air pump, the air pump is controlled to alternately and circularly pump air, and the cup body structure and the control program are greatly simplified.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to an extraction method for a food processor. Background technique [0002] With the improvement of people's living standards, tea drinks have gradually become an indispensable part of daily life. In order to improve the brewing efficiency, tea cups and other types of products have gradually appeared on the market. [0003] In the prior art, in order to improve the extraction efficiency, an air pump is often used to guide the water flow to reciprocate in multiple cavities to achieve the purpose of extraction. For example, the patent application number 201910036675.4 discloses a brewing method for extracting beverages. The overall scheme is equipped with multiple pots, and a water level sensor is installed at the corresponding position of each pot. The water level is identified by the water level sensor, and the air pump is controlled to alternately pump and inflate to drive ...

AI Technical Summary

Problems solved by technology

[0004] Although the above solution can realize the extraction of brewing substances, the overall structure is relatively complicated. The air pump needs to have two working modes of pumping and inflation at the same time, which makes the control procedure of the air pump in the pumping and inflation state cumbersome, and requires multiple pots. The bile chamber is used for liquid exchange, which makes the whole machine relatively large in size and inconvenient for users to use

In the working process, in order to prevent the air pump from sucking water into the pump during the pumping process, it is necessary to install a water level detection device, which greatly increases the application cost of the product.
