Embodiment Construction

[0034](1) Sterilization of solid-state fermentation materials: In the production process of solid-state fermentation to produce red yeast rice, protease, citric acid, ethanol, lactic acid, gibberellin, soy sauce, vinegar, white wine, protein feed, edible fungi, etc., solid-state The medium used for fermentation needs to be sterilized. Put the solid material to be sterilized into the material drum (5), send it into the microwave heating chamber (4) of the microwave heating equipment with a trolley, match the rolling ring on the material drum with the support wheel, and the drive shaft on the reducer Match the drum, then close the airtight door on the microwave sterilizer, open the intake valve (3), and press the sterile air into the microwave sterilizer through the air compressor and its sterile air system (13-19). The working pressure of sterile air is generally selected between 0.1Mpa-0.4Mpa, and the microwave heating time is 2-60 minutes, depending on the nature of the mater...

Abstract

The invention provides a method and a device for microwave sterilization. Problems of heating and sterilizing materials often happen in the prior food, pharmacy, agricultural byproduct processing, brewing, solid-state fermentation, chemical engineering and other fields. When various foods, fermentation materials and water-containing solid materials are treated with microwave, the temperature of the materials reaches more than 120 DEG C through pressurization to kill bacterial spores and thoroughly sterilize the materials. By adopting a method of pressing heated under-pressure aseptic air into a microwave device, the water-containing materials can be sterilized through microwave heating. Compared with the prior steam heating sterilization, the method can obviously shorten sterilization time and cause no environmental pollution, and has the advantages of simple device, low energy consumption, easy operation and automation-realizing easiness.

Description

[0001] 1. Involved technical fields [0002] The patented invention of "a microwave sterilization method and equipment" involves the fields of bioengineering, medicine, chemical industry, food and environmental engineering. 2. Background technology [0003] Microwave refers to electromagnetic waves with a frequency in the range of 300MHz to 300GHz. It was first used in military radar and communication fields. Later, people discovered that using microwaves to irradiate objects will produce thermal effects, causing the temperature of the irradiated objects to rise rapidly. This characteristic of microwave has been widely used in food and medicine industries, and a large number of households have entered the family. Its microwave generator and corresponding control technology have been relatively mature and perfect. There are two kinds of fixed dedicated microwave frequencies for industrial and daily use equipment. , That is, 915MHz and 2450MHz; recent scientific research shows t...
