Microwave sterilization apparatus

Abstract

The invention discloses a microwave sterilization apparatus, and belongs to the field of food sterilization equipment. The technical scheme of the microwave sterilization apparatus has the following key points: the microwave sterilization apparatus comprises a box on which an inlet and an outlet are arranged at the two ends; a conveyor structure is arranged inside the box so as to convey materialsfrom the inlet to the outlet; a microwave generation device, which transmits microwave in alignment to the direction of the conveyor structure, is fixedly connected with the interior of the box; a stirring structure is arranged inside the box so as to be used for performing stirring on the materials; the stirring structure comprises a stirring roller which is rotatably connected with the interiorof the box and a driving structure which drives the stirring roller to rotate; the bottom end of the stirring roller contacts with the conveyor structure; and the linear velocity direction of a sidewall of the stirring roller near the conveyor structure is opposite to the conveying direction of the conveyor structure. The microwave sterilization apparatus has more thorough sterilization effectson materials.

Description

technical field [0001] The invention relates to the technical field of food sterilizing devices, more specifically, it relates to a microwave sterilizing device. Background technique [0002] In order to improve the shelf life and safety of food, the food will be sterilized before packaging. Conventional technologies such as high temperature, drying, blanching, pasteurization, freezing, and preservatives can usually be used to achieve insecticidal and fresh-keeping of food, but this often affects the original flavor and nutritional content of food. The microwave insecticide sterilization is to make the microorganisms in the food be affected by the microwave thermal effect and the non-thermal effect at the same time, so that the proteins and physiologically active substances in the body are mutated, which leads to the growth delay and death of the microorganisms, and achieves food sterilization. The purpose of keeping fresh. [0003] At present, the Chinese utility patent w...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: affected by reflection, penetration, refraction, absorption, etc. during the actual sterilization process, there may be large differences in the microwaves received by each part of the same food material; when materials are piled up, microwaves may It will be absorbed by the upper material, so the sterilization effect on the bottom material is poor, which leads to the problem of incomplete sterilization
