Abstract

The invention discloses a panel-type solar drying machine based on heat conduction. The panel-type solar drying machine comprises a photic cover plate (1), a heat absorption plate (2), borders (4), a heat insulation layer (5), a bottom plate (6) and an object drying chamber (7); the photic cover plate (1) is arranged on an uppermost layer, and the heat absorption plate (2), the heat insulation layer (5) and the bottom plate (6) are sequentially arranged below the photic cover plate (1); the borders are (4) are arranged on the peripheries of the photic cover plate (1), the heat absorption plate (2), the heat insulation layer (5) and the bottom plate (6) for fixation; and a space between the heat absorption plate (2) and the heat insulation layer (5) is the object drying chamber (7). When sunlight radiates to the heat absorption plate (2), the heat absorption plate (2) is used for transferring heat to an object which is to be dried and ins close contact with the heat absorption plate (2) through temperature-difference drive, so that moisture inside the object is heated and evaporated and escapes from the drying machine, and thus, the object is dewatered and dried.

Description

technical field [0001] The invention relates to a solar drying device. Background technique [0002] The active solar drying technology combined with solar collectors has a long history of application and broad application prospects in the field of industry and agriculture. It is an effective, energy-saving and environmentally friendly technical method to accelerate the drying of agricultural products and expand industrial production capacity. Especially in recent years, dehydrated vegetables, dried fruits, tea, seafood and other agricultural and sideline products have moved from simple extensive agricultural production to mechanization and industrialization. In order to save energy and reduce consumption, improve the output and quality of dried products, active solar drying The technology has been extensively researched and developed. Patent CN101435654 provides a drying system based on the combination of liquid solar collectors and solar greenhouses, which has a complex s...
