Abstract

The invention provides plasma radio frequency coupling low-temperature cold sterilization equipment applied to fresh keeping of crayfishes. The plasma radio frequency coupling low-temperature cold sterilization equipment comprises a plasma radio frequency coupling low-temperature cold sterilization polar plate device, a high-temperature hot air device, a movable transmission device, a transmission belt adjusting device and a control device. Materials are conveyed from one end to the tail end through the movable conveying device, in the conveying process, the conveying belt enables the materials to move forwards stably under the action of the adjusting device and to be located in the middle of the whole equipment all the time, the materials are subjected to plasma and radio frequency cooperative sterilization in the plasma radio frequency coupling low-temperature cold sterilization polar plate device, and the sterilization effects of the plasma and the radio frequency are mutually complementary. Microorganisms in the materials are effectively killed and prevented from breeding, and the cold sterilization efficiency is remarkably improved. The plasma radio frequency coupling low-temperature cold sterilization equipment can effectively control the number and breeding of microorganisms in materials and prolong the shelf life of products under the condition of keeping the nutrition, flavor and quality of the crayfishes.

Description

technical field

[0001] The invention relates to the technical field of low temperature cold sterilization system equipment, in particular to a plasma radio frequency coupled low temperature cold sterilization equipment. Background technique

[0002] Crayfish in prefabricated conditioned aquatic products is rich in nutrients and high in water content, which is very suitable for the growth and reproduction of microorganisms. It is very easy to breed microorganisms in storage, transportation, sales and other links, causing product spoilage and deterioration, resulting in waste of resources. Effective control of the number and growth of microorganisms in crayfish is of great significance for extending product shelf life, food quality and safety. At present, domestic plasma cold sterilization mainly ionizes the gas in the prefabricated conditioned product, thereby producing ionized substances that can be sterilized. Although the plasma cold sterilization effect is better, it main...
