Processor of pulse electric field sterilizing equipment

Abstract

The present invention relates to a treatment device of equipment for sterilizing liquid products in the fields of food, biological, pharmaceutical and chemical industries by adopting high-intensity pulse electric field. Said treatment device is formed from material-treating cavity, two electrodes mounted in the material-treating cavity, inlet and outlet, in which said material-treating cavity is vacuum cavity, and can obtain good sterilizing effect.

Description

technical field [0001] The invention relates to a processor of equipment for sterilizing liquid articles in industries such as food, biology, pharmacy, and chemical industry by using a high-intensity pulsed electric field. Background technique [0002] There are three general heat sterilization methods: pasteurization; high temperature short-term sterilization; ultra-high temperature instantaneous method. These heat treatment methods will cause damage to the quality of food in several aspects such as heat-sensitive nutrition loss, flavor destruction, and sensory quality decline. For apple juice, pasteurization will cause 20% Vc loss, while ultra-high temperature instantaneous sterilization will reduce more than 90% of Vc content; for milk whey protein, the former will cause 0.4-10% denaturation , while the latter will cause more than 60% of denaturation. [0003] In addition to heat sterilization, other sterilization methods, such as microwave method, ultraviolet method, c...

AI Technical Summary

Problems solved by technology

[0003] In addition to heat sterilization, other sterilization methods, such as microwave method, ultraviolet method, cobalt 60 The γ-ray irradiation method, high static pressure method, membrane filtration method and chemical disinfectant method also have various shortcomings: chemical disinfectants are limited to disinfection of the environment and utensils, and cannot directly act on food; the penetration of ultraviolet rays is very weak, It is only effective for surface disinfection; microwave sterilization is efficient and practical, but it also heats up very high, and its sterilization mechanism is still heat; cobalt 60 The γ-ray residue is large, and the damage to food is also great; the cost of membrane filtration is high, and the membrane pores are easily blocked, and it is not suitable for fruit juice containing pulp particles; the high static pressure method has huge equipment and can only be operated intermittently, which is expensive and inconvenient to use

[0015] 1) It is easier to discharge between electrodes, and at the same time, the effective electric field strength in the material to be treated is very small, and the actual sterilization effect is relatively poor;

[0016] 2) There is no pretreatment device, the material is not degassed before entering the treatment chamber, and there is no prepolarization device;

[0017] 3) Composite synergistic treatment with ultraviolet and microwave methods is not considered, and the effect of single treatment is relatively poor
