1. Construction Goals: Advance the construction of grain drying capabilities at the sites of production, promote the replacement and upgrade of old drying facilities and equipment, upgrade intelligence, and transform energy sources to cleaner alternatives. The goal is to achieve a 65% drying capacity at grain production sites nationwide, basically meeting the drying needs at these sites.
2. Key Construction Tasks: Establish a grain drying system at the sites of production, combining drying points and drying centers. Drying points mainly complete singular drying operations, while drying centers should possess a certain grain storage capacity in addition to drying operations.
- Construct standardized grain drying centers (points). The construction content for drying points includes grain dryers, supporting selection machines, belt conveyors, elevators, dust removal systems, and drying plant buildings. Mainly focused on rice drying in the southern regions, the facilities are equipped with circulating dryers capable of handling less than 50 tons per batch. The construction content for drying centers includes grain dryers, supporting selection machines, pre-drying storage, post-drying storage, belt conveyors, elevators, dust removal systems, storage facilities, and drying plant buildings. For those equipped with combined circulating dryers, the batch processing capacity should be 50 tons or more; for those equipped with continuous dryers, the daily processing capacity should be 100 tons or more.
- Select appropriate grain drying facilities based on the type of grain, region, and scale.
- With regards to the short storage time characteristic of grain at production sites, in the northern regions, storage is mainly in steel silos supplemented with simple house-type warehouses, while in the southern regions, house-type warehouses are primarily used, supplemented with steel silos.
- Strengthen the promotion and application of energy-saving, efficient, and low-carbon drying facilities and equipment. Accelerate the environmental protection and energy-saving renovation of existing grain dryers, adopt heat pumps, electric heating, biomass fuels, natural gas, and solar energy as heat sources according to local conditions. Develop and innovate new grain drying and storage integrated technology using natural air and solar energy to reduce drying operation costs and improve equipment utilization and the value-added capability of grain storage. Accelerate the research and application of environmentally friendly cleaning, conveying, dust removal equipment, and multifunctional grain condition monitoring devices that match with the drying and storage facilities and equipment, promoting the green development of grain drying and storage adaptation technology.
