10. A constant temperature control method for preventing solidification of corn oil comprises the following steps according to a constant temperature system for preventing solidification of corn oil:
s1 initial tempering: firstly, respectively controlling rated difference values of heating units in a low-temperature water tank, a transition water tank and a high-temperature water tank and the outside room temperature through a control unit;
s2 selection loop: the working personnel control the required constant temperature loop according to the outside temperature through the control unit and switch according to the rise and fall of the outside room temperature in real time;
s3 adding an antifreezing agent: when the outside room temperature is low, workers add antifreeze into the loop by using an antifreeze adding module according to needs;
s4 cleaning: the whole loop is cleaned, maintained and maintained regularly;
s5 recovery: the impurities and the washing filtrate are recovered.
