Rice and fruit preservation method
For a long time, farmhouse granaries have lost 10-15% of food for one year due to insect pests, rat damage, and mold damage, and food can only be preserved for about one year. How to make it not only save food but also extend the shelf life? Not long ago, people in Wangcheng County, Hunan Province used biogas to find the answer. This type of “biogas storage granary†was created by the County Energy Office Li Qiming and others on the basis of a new type of storage granary promoted by the UN Food and Agriculture Organization. Long-horned plunders, maggots and other pests can effectively inhibit the reproduction of microorganisms, maintain grain quality, and avoid pesticide contamination in food storage, so that rice can be preserved for three years. At the same time, they also developed and created the "biogas storage and storage fruit storehouse," which uses biogas to contain more methane and carbon dioxide and methane non-toxic characteristics to regulate the gas composition in the storage environment, causing a certain degree of hypoxia, and controlling fruit respiration. Strength, reduce matrix consumption, achieve preservation effect, in which apple and citrus can be stored for up to 6 months.
