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

[0013] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] The device uses a porous flat solar air heat collector 2 as a heat source. Vent pipe 3 is equipped with valve. After the blower fan 4 starts, hot air is extracted from the porous flat solar air heat collector 2 and sent to the tumbling drying bin 5 to dry goods. The outside air enters the collector front chamber 16 from the air inlets 1 evenly distributed on both sides of the porous flat solar air heat collector 2, and enters the collector rear chamber 18 after passing through the small holes on the porous heat collector plate 17 to absorb heat. Finally, it enters the fan 4 from the air outlet 20 of the heat collector through the ventilation duct 3 . The tumbling drying bin 5 rolls under the drive of the motor 7, so that the dried objects inside are also tumbling thereupon. The hot air enters the drying bin from the air inlet 8 of the dryin...

Abstract

The invention discloses a rolling drier, which comprises a solar heat collector, a blower pipeline, a rolling drying chamber and a motor. Heat collection plates of the heat collector are multi-hole heat collection plates, roller wheels are arranged on a bracket of the drying chamber, and the drying chamber is connected with the motor through a gear structure and can roll under the drive of the motor. Teeth that are uniformly distributed on the periphery are arranged inside the drying chamber and can drive to-be-dried matter to roll over. The drying temperature of the system is around 30-50 DEG C, so that the quality of dried products is ensured.

Description

1. Technical field [0001] The invention relates to solar heat utilization technology and crop drying technology, in particular to a solar dryer which combines a porous flat solar air heat collector with a tumbling drying bin and drives the drying bin to rotate with a motor. 2. Background technology [0002] In the field of crop drying, most common drying heat sources are coal or oil heating, and the temperature of the hot air is around 200°C, which may easily lead to a decline in product quality. [0003] There are many patents about solar dryers at present, but due to reasons such as low utilization rate of solar energy and high cost, they still need to be popularized. A few existing related patents are listed below: [0004] The patent "rapid high-temperature solar dryer" (application number: 200620057287.2) proposes a solar dryer, the heat collecting part of which is a heat collecting plate, the air flows through the channel between the plate and the transparent cover to...
