Desolventizing drying device for traditional Chinese medicine

Abstract

The invention relates to a desolventizing drying device for traditional Chinese medicine. The device comprises a drying tower body, a motor and a rotating shaft, wherein an output shaft of the motor is in transmission connection with the rotating shaft; a plurality of heating drying mechanisms are arranged in the drying tower body, each comprising a heating plate, a paddle, a four-bar linkage assembly, a dreg discharging door, a bearing block, a connecting supporting saddle, a baffle plate and two rotating shafts; the heating plates and the paddles sleeve the rotating shafts; each bearing block is arranged at a part, close to a discharging port, of the bottom part of one end of the heating plate; the dreg discharging doors are connected with the first rotating shafts; two ends of the first rotating shafts are correspondingly rotatably connected with the bearing blocks and the bearing blocks at one end of the drying tower body; each connecting supporting seat is fixed to the bottom part of the other end of the corresponding heating plate; one end of each second rotating shaft is rotatably connected with the corresponding connecting supporting seat, and the other end of each second rotating shaft is rotatably connected with the bearing seats at the other end of the drying tower body; each four-bar linkage assembly is rotatably connected with the second rotating shaft of one heating drying mechanism and the second rotating shaft therebelow and adjacent thereto. The desolventizing drying device for the traditional Chinese medicine is high in drying efficiency, and solvents can be recycled.

Description

technical field [0001] The invention relates to a drying device, in particular to a traditional Chinese medicine precipitation drying device, which belongs to the technical field of traditional Chinese medicine drying. Background technique [0002] After the traditional Chinese medicine is extracted by solvent extraction, in order to prevent deterioration and facilitate storage, it must be dried in time. In recent years, a variety of drying equipment has been manufactured, and its drying capacity and effect have been greatly improved. These drying equipment are being continuously promoted and improved, and are suitable for mass production. [0003] At present, there are mainly two ways to dry traditional Chinese medicine in the market: the first is to use atomization heating to spray the solvent contained in the material into small droplets in the hot air, and the solvent is evaporated during the droplet falling process; the second is to use Infrared rays radiate far-infrar...

Problems solved by technology

[0003] At present, there are mainly two ways to dry traditional Chinese medicine in the market: the first is to use atomization heating to spray the solvent contained in the material into small droplets in the hot air, and the solvent is evaporated during the droplet falling process; the second is to use Infrared rays radiate far-infrared rays to the material, which intensifies the molecular movement and heats up inside, the temperature rises, and the residual solvent on the surface diffuses outward, which accelerates the outward transfer of the solvent inside the traditional Chinese medicine; drying is carried out, but the above two drying methods have Certain disadvantages include not only insufficient drying, which leads to low drying efficiency, but also the inability to recycle and reuse solvents, resulting in waste of resources, and at the same time, it is not energy-saving and environmentally friendly.
