Soybean milk heating control method

Abstract

The invention discloses a soybean milk heating control method. The soybean milk heating control method comprises the following steps: judging whether soybean milk is boiled or not; if the soybean milk is boiled, detecting the temperature T1 of the soybean milk by a first temperature sensor and the temperature T2 of a heater by a second temperature sensor, and judging whether a temperature difference delta T between the temperature T1 and the temperature T2 is more than a setting value or not; and if the temperature difference delta T is more than the setting value, reducing heating power of the heater to avoid overflowing of the soybean milk due to boiling. The soybean milk heating control method can be not influenced by the problems such as voltage fluctuation and NTC sensitivity so as to better avoid overflowing of the soybean milk.

Description

Technical field [0001] The invention relates to a method for controlling the heating of soybean milk. Background technique [0002] Soymilk is easy to overflow when making soymilk. In order to prevent it from overflowing, the traditional soymilk machine is equipped with a temperature sensor that detects the temperature of the soymilk, and controls the heating according to the detected soymilk temperature. For example, the heating control method disclosed in Chinese invention patent application 201110408633.2. However, because it is easily affected by factors such as the fluctuation of the power supply voltage of the heater and the sensitivity of the temperature sensor that detects the temperature of the soybean milk, the traditional solution still has shortcomings in solving the problem of easy overflow of the soybean milk during heating. For example, in the heating control method disclosed in 201110408633.2, after judging that the temperature of the soy milk reaches the boiling ...

AI Technical Summary

Problems solved by technology

However, because it is easily affected by factors such as the supply voltage fluctuation of the heater and the sensitivity of the temperature sensor for detecting the temperature of soybean milk, the traditional solution still has deficiencies in solving the problem of easy overflow of soybean milk when heating

For example, in the heating control method disclosed in 201110408633.2, after judging that the temperature of soybean milk has reached the boiling point, the milk is boiled with a slow fire. However, if the voltage is unstable and the power fluctuates, the soybean milk may still overflow when the milk is boiled. Sufficient heating and boiling effect to avoid overflow, and it is not easy to determine

Chinese utility model patent 200920151051.9 proposes setting a temperature sensor to detect the temperature of the heater, but this temperature detection is only to prevent the heater from being burned out due to excessive temperature or affect the taste or quality of the product, and to save energy
