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 pipe-type solar air heat collector as a heat source. After the fan 9 is started, the hot air is extracted from the pipe type solar air heat collector and sent into the dry storehouse to dry the goods. The outside air enters the collector pipe 2 from the air inlet 1 on the upper part of the ducted solar air collector, enters the collector pipe 3 after absorbing heat, and finally enters from the collector air outlet 4 through the collector outlet valve fan9. The hot air first enters the pressure equalization chamber 10 of the drying bin through the action of the fan 9, and then passes through the perforated sieve 11 and the dry matter 12, and the moisture is discharged from the air outlet 13 of the drying bin. The entire dryer reduces the length of the gas pipeline and reduces heat loss.

Abstract

The invention discloses a tube type integrated solar dryer, which comprises a solar heat collector, a fan, a ventilating tube and a drying bin. The solar heat collector is a tube type solar air collector, and a porous screen in the drying chamber is arranged in an inclination angle of 20 degrees. The drying temperature of the tube type integrated solar dryer ranges from 30 DEGC to 50 DEG C, and accordingly quality of dried products is guaranteed. Besides, since the solar air collector is integrated with the drying bin, heat loss is reduced, and the tube type integrated solar dryer is applicable to drying crops of 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 combines a pipeline solar air heat collector and a drying chamber into a whole. 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 absorb heat, and enters the drying device fo...
