Energy-collecting-type solar drying system

Abstract

The invention relates to an energy-collecting-type solar drying system, relates to a solar heat utilization technology, and also relates to the technical field of material and grain drying. The drying system mainly consists of a drying house the top of which is diaphanous, and a solar energy collecting chamber, wherein the air outlet of the solar energy collecting chamber is connected with an air supply pipe, and the other end of the air supply pipe is connected to the air inlet of the drying house. The drying system provided by the invention has the advantages of simple and reasonable structure and low manufacturing cost; and moreover, as dry high-temperature gas is transferred from the solar energy collecting chamber to the drying house through the air supply pipe, materials in the drying house can be dried. Furthermore, by using the drying system disclosed by the invention, a renewable energy source (solar energy) can be fully utilized to dry the materials according to different humidities of the materials and grains, thus the current phenomenon of drying materials completely dependent upon natural climate conditions can be effectively improved, and the system is suitable for drying materials and grain in overcast and rainy climate and can be used for ensuring the time for drying materials and grains and improving the quality.

Description

technical field [0001] The invention relates to solar heat utilization technology, and also relates to the technical field of material and grain drying. Background technique [0002] At present, most of the materials and food crops use the sun to directly dry food crops in sunny weather. Although there are some solar drying rooms, the promotion and utilization rate is not very high, because the existing solar drying rooms are more troublesome to build and the cost is high. It is bound to affect the drying of materials and grains. Moreover, if encountering cloudy and rainy weather, it will inevitably cause the situation that the grain cannot be dried in time, thereby affecting the drying time of the grain, and even more affecting the drying quality of the grain. Therefore, building a solar drying room with a simple structure and low cost has become an inevitable requirement of the above status quo. Contents of the invention [0003] The invention provides an energy-collec...
