Automatic temperature control energy-saving ohmic heating device for food material processing

The invention belongs to the technical field of food heating devices, and relates to an automatic temperature control energy-saving ohmic heating device for food material processing. The automatic temperature control energy-saving ohmic heating device for the food material processing comprises a variable voltage and variable frequency power supply portion, a wiring support box portion, a temperature control portion and a heating unit portion. Output alternating currents with different frequency and voltage can be set as needed by using a voltage and frequency regulation knob, requirements of heating of multiple conditions can be satisfied, a display screen displays an output current and output power in real time, and facilitates monitoring of energy consumption of a heating process. A heating target temperature can be set through a temperature controller as needed, when the target temperature is reached, the automatic temperature control energy-saving ohmic heating device for the food material processing ente
