Control method of soybean milk machine

Abstract

The embodiment of the invention discloses a control method of a soybean milk machine. The control method comprises the following step that during the heating process of the soybean milk machine, a motor is controlled for stirring soybean milk liquid, wherein the rotation speed of the motor changes along with the change of the temperature of the soybean milk liquid. Due to the technical scheme of the embodiment, soybean milk liquid is stirred at low rotation speed during the heating process of the soybean milk machine, the pre-grinding effect is achieved, the whole pulping period is saved, meanwhile, the temperature of the soybean milk liquid is enabled to be relatively uniform, and the overflow phenomenon caused by thermal inertia is reduced.

Description

technical field [0001] The embodiment of the present invention relates to the control technology of cooking equipment, especially to a control method of a soybean milk machine. Background technique [0002] At present, soybean milk machines use high-temperature pulping technology to reduce noise. Due to the limitation of the distribution of heating tubes, the temperature of the slurry during the heating process is uneven, and the temperature measurement is inaccurate, especially during the high-power heating process. The temperature of the slurry near the heating pipe is higher, while the temperature near the temperature sensor is lower. It takes a certain time for heat convection to make the temperature of the slurry uniform. Therefore, the temperature point is used to control the pulping process, and the temperature is usually deviated. [0003] In addition, the current pulping process is to heat the beans until they are close to boiling or boiling before starting the subs...

Problems solved by technology

[0002] At present, soybean milk machines use high-temperature pulping technology to reduce noise. Due to the limitation of the distribution of heating tubes, the temperature of the slurry during the heating process is uneven, and the temperature measurement is inaccurate, especially during the high-power heating process. The temperature of the slurry near the heating pipe is high, while the temperature near the temperature sensor is low. It takes a certain time for heat convection to make the temperature of the slurry uniform. Therefore, the temperature point is used to control the pulping process. Usually, the temperature is biased.

[0003] In addition, the current pulping process is to heat the beans until they are close to boiling or boiling before starting the subsequent pre-crushing. The heating and the motor work separately, which wastes the time of the pre-crushing stage, thus making the entire pulping cycle longer. At the same time, because the bean curd will fall off after soaking at high temperature for a period of time, it is easy to hit the wall of the cup body during the working process of the motor and cannot fall off, and it cannot fall off during the whole pulping process, causing a very bad experience for users.

[0004] In order to ensure the cooking degree of soybean milk, the stage of heating and touching the anti-overflow electrode is usually used in the pulping process. If a large fire is used in this stage, the slurry will overflow due to the effect of thermal inertia; Uniformity will lead to more heat accumulation at the bottom, and then in the beating process later, it will cause a sudden release of heat, resulting in overflow
