The invention utilizes solar energy drying cereal from three aspects: first utilizes the building structure in greenhouse, directly accepts sunlight, improves the temperature of hothouse, is equivalent to the dried grain of natural drying formula; Second utilizes the high-temperature hot-air of solar energy air heat collector, blows in the greenhouse drying shed, further improves the temperature of drying shed, quickens the cereal dry run; The 3rd utilizes underground heat accumulation tank heat energy, makes hothouse terrestrial surface radiation heat energy, is equivalent to dry by the fire the dried grain of a heatable brick bed formula, further quickens the cereal drying.More than three kinds of ways concentrate and use, the high wind of auxilliary again hair-dryer, the air that quickens drying shed flows, just can take the damp steam in the cereal out of rapidly, by the exhaust outlet of wall behind the greenhouse, row in atmosphere, the drying of realization cereal.
The characteristics of the invention are: (1) is simple in structure, and is cheap, easy and simple to handle, and drying cost is low, can suit measures to local conditions to build, and is fit to vast rural area and adopts on the spot; (2) fuel saving, according to the estimation of relevant technologies data, normal pressure is evaporation 1kg water down, needs 2.5*10 approximately
3The heat of kl/kg.For this reason, dry 1 ton of agricultural byproducts approximately will consume the raw coal more than 1 ton; (3) minimizing is to the pollution of environment.Atmosphere pollution comes from the flue dust and the waste gas of fossil energy burning back dischargings such as coal, oil, adopts solar energy drying cereal, not only saves fossil fuel, also can alleviate environmental pressure; (4) operating cost is low.With regard to initial cost, solar energy and conventional energy resource drying are more or less the same.But during system's operation, solar energy drying is much lower than the dry expense of conventional energy resource, generally has only about 30% of conventional energy resource operating cost.
