Abstract

The invention discloses a three-phase continuous flow induction heating green sterilization system and method, belonging to the field of light industry. By adopting a fluid system with a three-column magnetic circuit structure, a three-phase excitation technology based on liquid food windings has been developed, and electric power technology has been integrated to design its continuous flow pipeline system. The fluid food is used as a three-phase circuit, and its fluid internal resistance is reduced. Relatively The single-phase transformer structure has stability and versatility. The system adopts double storage pipes, which can further reduce the internal impedance of fluid food, increase the induced electric field strength and induced current density inside liquid food by 3 times, and have higher sterilization efficiency; The three-phase continuous flow induction heating green sterilization system provided has a sterilization temperature of 60-65°C and a processing time of <15s. It can provide green sterilization technology to many enterprises including liquid food enterprises and traditional Chinese medicine extract production plants.

Description

technical field

[0001] The invention relates to a three-phase continuous flow induction heat green sterilization system and method, belonging to the field of light industry. Background technique

[0002] The traditional heat conduction sterilization technology dominated by high temperature short-time heating or ultra-high temperature instantaneous heating has been widely used in various fields of industry, but in the food field, due to the relatively low heat transfer efficiency of liquid food, the required heat treatment time is too long, Therefore, local overheating of the food material will be caused, which will adversely affect the quality and nutritional value of the food. Using the thermal effect and non-thermal effect of the electric field, although electrode type treatment such as ohmic heating or high-voltage pulsed electric field can achieve rapid sterilization of liquid food, it is easy to cause electrochemical reaction, plate corrosion, reduction of processing ef...
