Description

Technical Field

[0001] The invention discloses a high-efficiency power air-drying bin, which mainly relates to the field of grain air-drying. Background Art

[0002] Grain air drying plays an extremely important role in the circulation of grain, especially when there is a rainy season during the grain harvest season. If the grain cannot be dried and dehumidified quickly, the entire storage will face great problems. The existing grain drying is to reduce the moisture content of the grain by drying in a drying tower. The problem is that the drying cost is extremely expensive, and the equipment investment cost of the drying tower remains high. Especially at the moment when environmental protection requirements are extremely stringent, coal with the highest calorific value is strictly restricted in some areas, and the operating costs of using biomass, diesel, gas, etc. have risen. Grain is a low-value crop, which puts grain drying in an extremely embarrassing position. Traditional large-scale drying equipment has relatively low automation, and the operation of the equipment cannot be separated from a large amount of human resources, and the comprehensive operating costs continue to rise.
