Constant-temperature and constant-humidity anti-mildew device for rice storage

Abstract

The invention relates to the technical field of grain storage, and provides a constant-temperature and constant-humidity anti-mildew device for rice storage. The constant-temperature and constant-humidity anti-mildew device comprises an oxygen control mechanism and a constant-temperature mechanism, the oxygen control mechanism comprises an incomplete gear, the back surface of the incomplete gear is movably connected with a spiral rotating plug, the surface of the spiral rotating plug is movably connected with an air control pipe, and a humidifying bin is formed in the surface of the air control pipe. According to the constant-temperature and constant-humidity anti-mildew device for rice storage, a water bag is expanded through water evaporation, the effect of absorbing and sensing the temperature of a granary is achieved, when the temperature of the granary is too high, the water bag pulls down a connecting block through a linkage rod set, a linkage rod, a reset spring and the incomplete gear are used in cooperation, and the effect of adjusting the force direction is achieved; and the incomplete gear rotates to drive a toothed plate to move, the toothed plate changes the resistance value of a rheostat through a sliding piece, the effect of reducing the temperature is achieved, the granary is wrapped with cooling liquid, rapid cooling is conducted, when the temperature is recovered, suction and recovery are conducted, and the hysteresis quality of temperature adjustment is avoided.

Description

technical field [0001] The invention relates to the technical field of grain storage, in particular to a constant temperature and humidity anti-mildew device for rice storage. Background technique [0002] During the storage of rice, it will undergo aerobic respiration and anaerobic respiration, which will cause mildew in the rice. Mold and mycotoxins will pollute the rice. The mildewed rice will cause great harm to human health, and chronic Poisoning and carcinogenic problems, with the development of the times, the storage of rice has become very important. [0003] In the prior art, rice will undergo aerobic and anaerobic respiration during storage. At the beginning, the aerobic respiration of rice will consume oxygen continuously, which will increase the subsequent anaerobic respiration, which will cause the rice to continuously accumulate alcohol and cause the rice to lose weight. Black, rotten, and when the storage environment is controlled at a constant temperature, t...

Problems solved by technology

[0003] In the prior art, rice will undergo aerobic and anaerobic respiration during storage. At the beginning, the aerobic respiration of rice will consume oxygen continuously, which will increase the subsequent anaerobic respiration, which will cause the rice to continuously accumulate alcohol and cause the rice to lose weight. Black, rotten, and when the storage environment is controlled by a constant temperature, the temperature will evaporate the water inside the rice, causing the humidity of the storage environment to change. Therefore, a constant temperature and humidity anti-mildew device for rice storage came into being.
