Problems solved by technology

[0002] In the field of crop drying, the common drying heat sources are mostly coal or oil heating, and the temperature of the hot air is around 200°C, which will easily lead to a decline in product quality
[0003] At present, there are many patents on solar dryers, but due to the low utilization rate of solar energy and high cost, it has yet to be promoted.

Embodiment Construction

[0012] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0013] The device uses the porous flat plate solar air heat collector 2 as the main heat source, and the heating furnace 9 as the auxiliary heat source. When the light is sufficient, after the fan 3 is started, the hot air is extracted from the porous flat plate solar air collector 2 and sent into the drying bin to dry the goods. The outside air enters the front cavity 15 of the collector from the air inlets 2 evenly distributed on both sides of the perforated flat solar air collector 2, passes through the small holes on the perforated thermal collector 13 to absorb heat, and then enters the rear cavity 16 of the collector, Finally, it enters the fan 4 from the outlet of the collector through the outlet valve of the collector. When the light is insufficient or at night, the heating furnace 9 can burn fuels such as wood or coal to heat the air. The ou...

Abstract

The invention discloses an auxiliary heating flat plate integral type solar drier, which comprises a flat plate solar air heat collector, a heating furnace, a blower, a pipeline and a drying chamber. Heat collection plates of the heat collector are multi-hole heat collection plates, a perforated sieve of the drying chamber is placed at an inclination angle of 20 degrees, and the heating furnace uses crop straws as fuel. The entire system constitutes a compact whole, and the air heat collector and the drying chamber enclose to form a drying space. The drying temperature of the system is around 50 DEG C, so that the quality of dried products is ensured. Also, the system is compact in designed structure and high in heat efficiency, and is suitable for crop drying quantity demanded by a single rural family.

Description

1. Technical field [0001] The invention relates to solar thermal utilization technology and crop drying technology, in particular to a solar dryer which integrates a porous flat plate solar air collector and a drying bin into a whole, uses a fan to actively supply air, and uses a heating furnace as an auxiliary heat source. 2. Background technology [0002] In the field of crop drying, the common drying heat source is mostly coal or oil heating, and the temperature of the hot air is about 200 ℃, which easily leads to the decline of product quality. [0003] At present, there are many patents on solar dryers, but due to the low utilization rate of solar energy and high cost, they still need to be promoted. Listed below are several existing related patents: [0004] The patent "Fast High Temperature Solar Dryer" (application number: 200620057287.2) proposes a solar dryer, the heat collecting part is a heat collecting flat plate, the air flows through the channel between the f...
