Embodiment Construction

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

[0013] This device uses coiled tube type solar air heat collector 7 as heat source. Hot air is extracted from coiled tube solar air heat collector 7 after blower fan 9 starts and sent into the drying storehouse to dry goods. The outside air enters the serpentine duct 5 from the upper air inlet 1 of the serpentine solar air heat collector 7 , fully exchanges heat with the serpentine elbow 5 , and finally enters the fan 9 from the heat collector outlet 2 through the ventilation duct 8 . The hot air first enters the pressure equalization chamber 11 of the drying bin through the action of the fan 9, and then passes through the perforated sieve 12 and the dry matter 14, and the moisture is discharged from the air outlet 15 of the drying bin. The entire dryer reduces the length of the gas pipeline and reduces heat loss.

Abstract

The invention discloses a coil pipe integral type solar drier, which comprises a solar heat collector, a blower, a ventilating pipeline and a drying chamber. Heat collection plates of the heat collector are metal plates, the sunny sides of the metal plates are coated with selective absorption coatings, and snake bends are welded on the back sides of the metal plates, and a perforated sieve of the drying chamber is placed at an inclination angle of 20 degrees. The drying temperature of the system is around 30-50 DEG C, so that the quality of dried products is ensured. In addition, the air heat collector and the drying chamber constitute a whole with a compact structure, and the coil pipe integral type solar drier reduces heat loss 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 coiled 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...
