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

[0014] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] The device uses a pipe-type solar air heat collector 1 as a main heat source, and a heating furnace 2 as an auxiliary heat source. When the light is sufficient, the blower fan 3 starts to extract hot air from the pipe-type solar air heat collector 1 and send it into the drying bin to dry the goods. The outside air enters the heat collector exhaust pipe 11 from the evenly distributed air inlets 9 on the upper end of the pipe-type solar air heat collector 1, and merges into the heat collector header 12, and finally enters the fan 3 from the air outlet 15 of the heat collector. When the light is insufficient or at night, the heating furnace 2 can burn fuels such as wood or coal to heat the air. External air enters the heating chamber 17 from the heating furnace air inlet 16 to absorb heat, and enters the fan 3 from the heating chamber air outlet...

Abstract

The invention discloses an auxiliary heating pipeline integral type solar drier, which comprises a pipeline solar air heat collector, a heating furnace, a blower, a pipeline and a drying chamber. A heat collection part of the heat collector comprises collection pipes and exhausting pipes, the 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 heat utilization technology and crop drying technology, in particular to a solar dryer which integrates a pipeline solar air heat collector and a drying chamber, 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, 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...
