High-voltage pulse electric field sterilizing treatment chamber for monitoring strength and temperature of electric fields on line

Abstract

The invention discloses a high-voltage pulse electric field sterilizing treatment chamber for monitoring the strength and temperature of electric fields on line. Two coaxial treatment chamber bodies are formed from two tubular high-voltage electrodes and tubular grounding electrodes, the two tubular high-voltage electrodes are partitioned by an insulating tube, and both ends of the tubular grounding electrodes are sheathed with insulated protecting sleeves, thereby a coaxial continuous high-voltage pulse electric field treatment chamber is formed. A Hall element and a linear digital temperature sensor are installed in the treatment chamber, signals are sent into a single-chip machine after conditioning, amplification and A / D conversion, and then each parameter is displayed by a liquid crystal display module. The high-voltage pulse electric field sterilizing treatment chamber can ensure the distributing uniformity of the electric fields and also improve the flow characteristics of liquid materials to improve the treatment flow, and avoids the occurrence of dead zones, and the treatment effect is obviously improved; and moreover, the high-voltage pulse electric field sterilizing treatment chamber quantitatively monitors the strength and temperature values of the electric fields in the treatment chamber on line in real time and can provide data support for the simulated modeling of a treatment system.

Description

technical field

[0001] The invention relates to a sterilization treatment device, in particular to a high-voltage pulse electric field sterilization treatment room for online monitoring of electric field intensity and temperature. Background technique

[0002] As one of the most researched non-thermal processing technologies in recent years, the high-voltage pulsed electric field sterilization technology not only has a good effect of sterilizing and inactivating enzymes, but also can maintain the freshness of food to the greatest extent, and the processing temperature is low and the processing time is short. The shelf life of food can also save energy, save costs, and have no pollution to the environment. The high-voltage pulse electric field sterilization system is mainly composed of two parts: a high-voltage pulse generator and a sterilization treatment chamber. The processing chamber is used to load the processed samples and place the electrodes, and the samples can be u...
