[0046] Working principle:

[0047] The moisture-proof and de-insect storage device for rice processing is a sealed storage tank for storing and repeatedly cooling rice. The insects that grow on rice are commonly known as rice insects, also known as rice weevils. Rice weevils are insects of the family Curculionidae and the genus Sitophilus. They feed on rice grains during the earing stage and lay eggs in the oviposition sites. In other words, rice insects are self-contained. Rice insect eggs are long oval in shape, with one end slightly swollen. The egg length is about 0.6-0.7 mm. Rice weevils have weak cold tolerance and start to die after 21 days at 5℃. Therefore, the sealed storage tank is designed to be repeatedly cooled and decontaminated, keeping the rice in a low-temperature and dry environment. During the circulation cooling and decontamination, impurities or insect eggs separated from the rice grains are blown out, achieving moisture-proof and de-insect storage of rice.
