Drum-type microwave sterilizer

Abstract

The invention particularly relates to a drum-type microwave sterilizer, which comprises a case. A microwave emission system for sterilizing a product and a sterilization cavity for accommodating the product are arranged in the case; the microwave emission system is arranged outside the sterilization cavity; the microwave emission system comprises a microwave emitter and a microwave waveguide; themicrowave waveguide is connected with the microwave emitter and the sterilization cavity; microwaves emitted by the microwave emitter are introduced into the sterilization cavity through the microwavewaveguide; a vertical roller for uniformly sterilizing products is arranged in the sterilization cavity; and the vertical roller is rotatably fixed on the side wall of the sterilization cavity. The vertical roller is arranged in the sterilization cavity, a product to be sterilized is placed in the vertical roller, and the product in the roller fully receives microwave radiation through rotary stirring of the vertical roller, so that the full sterilization effect is achieved, the microwave radiation receiving degree of the product is more uniform through stirring, and the sterilization efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of sterilization equipment in the food and drug industry, and in particular relates to a drum type microwave sterilizer. Background technique [0002] At present, most of the existing sterilization technologies in the industry use steam, high temperature, ultraviolet rays, etc. Their disadvantages are that the temperature is too high during sterilization, which affects the taste and nutritional content of food and medicine, or the sterilization is not thorough, such as ultraviolet sterilization. In this way, it can only sterilize the surface of the food, and the ultraviolet rays cannot penetrate deeper into the food to sterilize, so the complete sterilization effect cannot be achieved. With the improvement of people's food quality requirements, the state has repeatedly proposed to ban or use with caution food additives such as food preservatives that are harmful to the human body. Then, food sterilization ha...

AI Technical Summary

Problems solved by technology

How to quickly and thoroughly realize sterilization and realize industrial automation has become a difficult point in this industry. The biggest disadvantage of the current high-temperature sterilization method is that the sterilization time is long, and each sterilization time can be completed in several hours or even longer. After sterilization, the nutritional content of food will be lost greatly, and the original taste and texture of food will be changed, and high temperature treatment will waste a lot of energy, which is not conducive to sustainable development
