Solar drying device

Abstract

The invention relates to a solar drying device. The solar drying device comprises a box body, wherein the top and the back side of the box body are open, glass cover plates are respectively arranged in the open positions of the top and the back side of the box body, heat collecting plates are respectively connected to the inner sides of the glass cover plates by virtue of connecting frames, cavities are formed between the glass cover plates and the heat collecting plates, a storage chamber is formed in the box body near the bottom of the front part, a drying chamber is formed above the storagechamber in the box body, a temperature sensor and a humidity sensor are arranged in the drying chamber, the temperature sensor and the humidity sensor are connected with a controller, hot air channels are formed between the drying chamber and the left and right side walls of the box body, heat storage fans are arranged in positions, which correspond to the hot air channels, of the left and rightside walls of the box body, a circulating fan is arranged behind the drying chamber in the box body, an electric heating fan and a dehumidifying fan are arranged in the drying chamber, and an energy storage body is arranged behind the storage chamber in the box body. The solar drying device has the advantages of reasonable structural design, energy conservation and good drying effect.

Description

technical field [0001] The invention belongs to the technical field of drying equipment, and in particular relates to a solar drying device. Background technique [0002] Food processing includes many processes such as sorting, crushing, separating, mixing, sterilizing, refrigeration and drying of raw materials, and the drying process is a key link to ensure food quality. Most foods are wet materials containing a lot of water. If the food as a commodity contains too much water, it will cause the life activities of microorganisms, cause food corruption or shorten the shelf life of food, and increase transportation costs. Drying food can prevent the reproduction of microorganisms in food, facilitate storage, and reduce the volume and weight of food, thereby reducing transportation costs. However, the current vegetable drying equipment consumes a lot of energy and the drying effect is relatively poor; therefore Therefore, it is very necessary to provide a solar drying device w...

Problems solved by technology

Most foods are wet materials containing a lot of water. If the food as a commodity contains too much water, it will cause the life activities of microorganisms, cause food corruption or shorten the shelf life of food, and increase transportation costs.

Drying food can prevent the reproduction of microorganisms in food, facilitate storage, and reduce the volume and weight of food, thereby reducing transportation costs. However, the current vegetable drying equipment consumes a lot of energy and the drying effect is relatively poor; therefore , it is very necessary to provide a solar drying device with reasonable structure design, energy saving and good drying effect
