Ventilating device for refrigeration house fresh-keeping storage

Abstract

The invention discloses a ventilating device for refrigeration house fresh-keeping storage, and belongs to the field of refrigeration house fresh keeping. The ventilating device comprises a shell, theexterior of the shell is fixedly sleeved with a mounting plate in a connected manner, the top and the bottom of one side of the shell are fixedly sleeved with an air outlet pipe and an air inlet pipecorrespondingly in a connected manner, an air conveying pipe is fixedly connected to the other side of the shell in a sleeving manner, a muffler sleeve is fixedly connected to the exterior of the airconveying pipe in a sleeving manner, an air exhaust solenoid valve is fixedly installed on the outside of the air outlet pipe, one end of the air outlet pipe is in threaded and sleeved connection with a deodorizing sleeve, and one side of the deodorizing sleeve is in threaded and sleeved connection with a polluted air pipe. According to the ventilating device for refrigeration house fresh-keepingstorage, the deodorizing sleeve, an activated carbon board, a sponge block, a thin pipe and a liquid addition funnel are arranged, in the process of air exhausting of a refrigeration house, chemicaland physical manners are conveniently used for dual filtering of irritating odors in polluted air, the purification effect of the polluted air is improved, the problem of pollution caused by direct discharge of the polluted air into air is avoided, and the living environment of people is protected.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping in cold storage, and in particular relates to a ventilation device for fresh-keeping in cold storage. Background technique [0002] Fresh-keeping refers to keeping perishable foods such as vegetables, fruits and meat fresh. Fresh-keeping cold storage is a storage method that inhibits the activity of microorganisms and enzymes and prolongs the long-term storage period of perishable foods. Cold storage technology is a low-temperature storage method for modern perishable foods. The main way of preservation can not only reduce the incidence of pathogenic bacteria and fruit rot, but also slow down the respiratory metabolism process of vegetables, so as to prevent decay and prolong the storage period. [0003] However, most of the existing perishable foods are kept fresh in the cold storage. Since the storage in the cold storage is almost completely closed, even if the internal temperature is very...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing perishable foods are kept fresh in the cold storage. Since the storage in the cold storage is almost completely closed, even if the internal temperature is very low, there are many foods inside. The long-term storage makes the air inside the cold storage If it is dirty and produces a pungent smell, it is necessary to regularly ventilate the air inside the cold storage. For this reason, we propose a ventilation device for fresh-keeping storage in the cold storage
