Novel sterile room with physically and chemically combined multistage sterilization and operating method thereof

Abstract

The invention discloses a novel sterile room with physically and chemically combined multistage sterilization and an operating method thereof. The novel sterile room comprises a first buffer room, a second buffer room and an inoculation room. The first buffer room is provided with a first sealing door for in-and-out of people and cargoes, and an air inlet for inflow of outer fresh air. A separating wall between the first buffer room and the inoculation room is provided with an air filter. A gauze window and an inoculation room door are arranged between the inoculation room and the second buffer room. A second sealing door is arranged between the second buffer room and the first buffer room. The second buffer room is provided with an exhaust fan for exhausting air outwards. The novel sterile room overcomes a defect of low sterilization capability for hybrid bacteria in piles, wall body or pipeline aperture gaps or bacteria rod surface. Furthermore irritant gas after smog fumigation is repelled by means of clean air, thereby realizing no reflowing of aerosol, protecting human body health, and realizing no oxidation corrosion of main instruments by the aerosol.

Description

technical field [0001] The invention relates to the technical field of aseptic inoculation of edible fungi, in particular to a new type of aseptic room combined with physical and chemical multi-stage sterilization and a working method thereof. Background technique [0002] Currently, there are several methods for the inoculation of edible fungi. The first is inoculation in a conventional aseptic room. The principle is to filter out foreign bacteria through a filter, sterilize the inoculation room with an ultraviolet lamp, and wipe the surface with alcohol during inoculation. Its advantage is that it does not need chemical fumigation. Its disadvantage is that it has high requirements on walls, floors, pipes and the environment. The ultraviolet ray has a weak ability to sterilize objects and spaces beyond 2 meters, and the production of edible fungi is large. Often only wall stacks can be used for stacking. Conventional aseptic rooms are not capable of sterilizing bacteria in ...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to solve the problems existing in the above-mentioned prior art, and provides a new type of aseptic room combined with physical and chemical multi-stage sterilization and its working method, which overcomes the impact of conventional aseptic rooms on the miscellaneous bacteria in the stack, the impurities in the wall or the pores of the pipeline. The sterilizing ability of bacteria and bacteria on the surface of the bacteria rod is not strong, and the irritating gas after aerosol fumigation is expelled with clean air, the aerosol does not flow back, and the health of the human body is protected. The main equipment is not oxidized and corroded by the aerosol
