Additional energy drying device of solar energy drying apparatus

Abstract

The invention discloses a solar energy drying equipment and an energy drying device for drying the herbage, the herbage seed or the like in the agricultural product and the Chinese herbal medicine in the rain, which is characterized by the following: installing the electric heat section which comprises a curved blast pipe and an electric heater at the blast pipe lower of the plate collector; increasing a plurality of heaters which burn with the coal or the fuel oil or the fuel gas or the agronomic crop stem separately at the storage calorifier lower of the vacuum tube collector hot air drying system. When it rains, the electric heater is stared and the cold air from the blast pipe of the plate collector which is heated by the electric heater through the bend blast pipe blows in the drying storage for drying the material, or the heater which burn with the coal or the fuel oil or the fuel gas or the agronomic crop stem is started, the water in the storage calorifier is heated and the snakelike blast pipe is heated, the internal hot air is used for drying the material in the storage. The invention achieves the drying operation in the rain, which achieves all-weather continuous drying operation, and keeps the drying quality of the drying material.

Description

Technical field [0001] The invention belongs to a kind of drying equipment. The device uses electricity, coal, fuel oil, gas or crop straw as the energy source, and can cooperate with the alternate heating type solar drying equipment. Drying can also realize drying operations in rainy days, and finally dry agricultural products and Chinese herbal medicines into finished products that can be stored for a long time or further processed. Background technique [0002] In the processing of pasture, forage seeds and other agricultural products and Chinese herbal medicinal materials, artificial rapid drying is usually used to dry them to preserve their effective nutrients and prevent them from going bad and moldy after long-term storage. At present, natural drying is mainly used in China. Because the time required for drying is too long, the effective nutrients of agricultural products and Chinese herbal medicines are seriously lost. The solar drying equipment used in foreign coun...
