FIELD: heating.
SUBSTANCE: method of controlling the heating unit of a cooking device, a cooking device, and a device for producing soy milk are provided. Method of controlling heating unit (104) of the cooking appliance includes: identification (S110) of conductive property (102) of the water and food mixture (101), at that conductivity property (102) of the mixture indicating the degree of risk of overflow of mixture (101); and sending (S120) control signal (103) with respect to heating unit (104) for heating mixture (101) based on detected conductivity property (102) of mixture (101) for controlling the operation of heating unit (104).
EFFECT: with the help of embodiments for the presented disclosure, the overflow problem can be solved effectively with a low cost, the design of the cooking appliance can be greatly simplified, and at the same time, the temperature will remain close to the boiling point, that means the heating process is effective.
