Soy milk preparation method and fuzzy control electrical heating full automatic soyabean milk machine

Abstract

The invention discloses a method for preparing soya milk, which comprises the steps of: firstly, preheating the water in which beans are soaked to any temperature between 65 and 75 DEG C, controlling the speed of temperature rise and continuing heating the beans for five to three hundred and sixty seconds and then stopping heating, mashing the beans immediately, heating to boil the beans after mashing, and then adjusting the heating power automatically according to temperature to prevent overflow, continuing heating intermittently and cooking, and keeping boiling for four to ten minutes to prepare the soya milk; meanwhile based on the preparing method, the invention provides a fuzzy control electric heating fully automatic soya milk machine, which mainly makes the soya milk preparing method programmed and solidified in a control circuit board in a systemized way, and realizes intelligent control of soya milk processing via a singlechip. The machine can introduce the functions of adjusting the heating power automatically according to the temperature and controlling the speed of temperature rise in the heating periods during processing the soya milk.

Description

technical field [0001] The invention relates to a preparation method of soybean milk and a fuzzy control electric heating automatic soybean milk machine. Background technique [0002] Due to the lack of research on soymilk preparation methods, especially the systematic research on the beating temperature, beating time, beating method and heating and boiling temperature, time and method in the soymilk preparation method; the quality of soymilk produced by the automatic soymilk machine is Unsatisfactory indicators such as taste are unsatisfactory. [0003] Practice has proved that: the traditional method of soaking beans thoroughly, beating with cold water, and then boiling the soy milk, the taste of the soy milk is obviously astringent, and the smell is not mellow. As the temperature of the beating and blending water rises, the taste of the prepared soy milk is significantly improved and the mellowness increases. However, when the temperature of the blending water exceeds 87...

AI Technical Summary

Problems solved by technology

[0004] The deficiencies of the existing full-automatic soybean milk machines are mainly manifested in the following aspects: the control circuit part of these automatic soybean milk machines generally adopts integrated logic gate circuits to drive relay switches To control the heating element and motor work, multiple sets of logic chips such as comparators, timers and triggers are often used. In addition, the power supply generally uses a power supply circuit composed of a power transformer and a full-wave bridge rectifier to integrate logic gates. The circuit is used for power supply, there are many components, and the circuit structure is complex; not only the manufacturing cost is high, but also the failure rate of the entire control circuit part is high, and the anti-interference ability is poor

[0005] On the other hand, due to the fact that the existing automatic soybean milk machine mainly uses pure hardware to realize the technological process of making soybean milk, especially the relay switch is used to control the heating element. , the heating power can only be full power or half power. In the boiling stage of the pulp, the power will generally be too high and overflow will
