Description

Technical field

[0001] The invention belongs to the technical field of grain storage and fresh-keeping. Specifically, it belongs to the technical field of prevention and control of main storage pests and molds in the storage process of rice, rice, wheat and other grains. It relates to the use of microwave treatment and heat recycling to save energy and completely kill the main storage pests (including Various insect states such as adults, eggs, etc.) and methods and special equipment for reducing rice mold Background technique

[0002] The research on insect and mildew prevention during grain storage in my country mainly focuses on the raw materials after harvest. At present, the commonly used insect prevention methods are chemical fumigation represented by phosphine (or aluminum phosphide) and methyl bromide. Taking rice as an example, chemical fumigants have a good control effect on adults, but they have poor control effects on eggs and mold, and ...
