Technical Field

The invention relates to the technical field of industrial sterilization of edible fungi, in particular to an anti-pollution process in a sterilization link.

Background

The sterilization is an indispensable process in the industrial production process of edible fungi, the sterilization in the production process of the edible fungi is to pump out cold air in a sterilization pot by a vacuum pump through the flow of water to enable the sterilization pot to be in a negative pressure state, then saturated hot air is input, high-temperature and high-pressure steam is used as a medium, the latent heat of the steam is large, the penetrating power is strong, the sterilization pot can be quickly penetrated into a cultivation bottle, microbial protein is denatured and solidified under the action of high temperature and high pressure to inactivate to meet the sterilization requirement, and the sterilization function is as follows: removing harmful impurities, removing harmful substances in the culture medium, softening the culture medium, solidifying the shape of the culture medium, sterilizing by a sterilization program, and bottling the culture medium to meet the growth requirement of the flammulina velutipes strains.

The current sterilization technique is when the sterilization finishes, and generally directly open the interior door and go out of the stove, leads to the whole pressure release of stove steam volume to the outside through new trend system and room pressure release mouth between the clean area buffering, and the space steam volume of pressure release to the clean area buffering is very big, and visibility is low when having staff's operation, and ground steam is big, and fork truck operation potential safety hazard is big, and roof comdenstion water waits to cause the great problem of pollution risk more.

In order to solve the problem of high pollution risk caused by the operation process in the sterilization link in the prior sterilization technology and reduce the steam amount in a buffer room of a clean area so as to reduce the production pollution risk, the pollution prevention process in the sterilization link is provided.
