Double-helix drying equipment and drying method

Abstract

The invention relates to double-spiral drying equipment. The double-spiral drying equipment comprises first spiral drying equipment and second spiral drying equipment, and each of the first spiral drying equipment and the second spiral drying equipment comprises a heat preservation box body, a spiral conveying mechanism and a drying mechanism, wherein the spiral conveying mechanism is arranged in the heat preservation box body and comprises a spiral sliding rail and a conveying mesh belt which are arranged in the heat preservation box body; the drying mechanism is arranged on the rear side of the heat preservation box body and used for supplying heat into the heat preservation box body, and the input end of the conveying mesh belt in the first drying equipment and the output end of the conveying mesh belt in the second drying equipment are located at the same height. According to the double-spiral drying equipment, a double-spiral structure is adopted, so that the equipment size is reduced, meanwhile, the requirement for the drying amount is met, and the occupied area of the drying equipment is saved; an air source heat pump is adopted as a drying heat source, so that heat supply is stable, and the drying quality can be guaranteed; dried raw materials are input from the bottom of the left side of the first spiral drying equipment and output from the bottom of the right side of the second spiral drying equipment, so that conveying of the dried raw materials is facilitated, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a double-screw drying equipment and a drying method. Background technique [0002] Agricultural products such as mushrooms, fruits, etc., sometimes need to be dried and dried, and drying equipment is needed to dry them. At present, mesh belt dryers or drying rooms are mostly used in the market for drying operations. Mesh belt dryers The mesh belt conveyor is set in the oven, and the mesh belt conveyor transports the raw materials to be dried and dried in the oven. Since a long oven is needed to ensure the drying effect, this kind of drying equipment occupies a relatively large volume and requires A large enough space increases the cost of use. Drying in the drying room is mainly to set up drying racks in the drying room, and use trays to support raw materials for drying. The drying capacity of the drying room is small, and if a larger drying capacity , you need multiple...
