Description

technical field [0001] The invention relates to a pulse electric field treatment chamber using semiconductor cooling technology, in particular to a novel pulse electric field treatment chamber and method. Background technique [0002] Pulsed electric field treatment is a means of treating cell membranes by generating alternating pulsed electric fields and pulsed magnetic fields through power supply and pulse generating device. A large number of studies on the mechanism of action and impact of carbohydrate components and other food components have been carried out. Generally, the pulse electric field processing system mainly includes: power supply device, pulse generating device, pulse electric field processing chamber, cooling system, temperature measurement system and other parts. [0003] Although pulsed electric field treatment is considered as a non-thermal technology, since the current flowing through the food will generate ohmic heat, the temperature increase is inevi...

AI Technical Summary

Problems solved by technology

Due to the heating effect of the pulsed electric field on the food, it is complicated to directly use the cooling water circulation circuit, the degree of modularization is low, and the cooling efficiency is low, and the temperature of the pulsed electric field treatment chamber cannot be adjusted in real time.
