Traditional Chinese medicine material drying device

Abstract

The invention provides a traditional Chinese medicine material drying device which is characterized in that a sealing cover is rotationally connected with a dehumidification port of each dehumidification shield; a negative pressure valve is fixedly connected into each dehumidification shield and connected with the corresponding sealing cover; each sealing cover can be driven by the corresponding negative pressure valve to open and close; two air guiding plates are fixedly connected with the two sides of each dehumidification port in a dehumidification air duct, and combined to form the shape of a horn mouth; one side of each air guiding plate is fixedly connected with the bottom surface of the dehumidification air duct; and an air guiding bent plate is fixedly connected with the other side of each air guiding plate. Through the traditional Chinese medicine material drying device provided by the invention, the medicine material drying quality can be guaranteed, the medicine material drying speed can be improved, the drying time can be shortened, the power consumption of the traditional Chinese medicine material drying device can be lowered by adopting an air-source high-temperature heat pump, and then the medicine material processing cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of medicinal material drying, and in particular relates to a traditional Chinese medicine medicinal material drying device. Background technique [0002] As we all know, the purpose of using a drying device in the pharmaceutical industry is to remove some raw materials, moisture or solvents in semi-finished products, so as to improve product quality, facilitate material processing, use, and facilitate transportation and storage. Existing drying boxes generally include material conveying Belt and heating drying device, but the existing equipment generally has the following problems: hot air blows continuously across the surface of the mesh belt to dry the materials on it, and the supply of hot air is uneven, resulting in uneven drying of medicinal materials; The number of conveyor belts is generally one, so that the material enters from the feeding end and is finally sent out from the discharging end. The who...

[0002] As we all know, the purpose of using a drying device in the pharmaceutical industry is to remove some raw materials, moisture or solvents in semi-finished products, so as to improve product quality, facilitate material processing, use, and facilitate transportation and storage. Existing drying boxes generally include material conveying Belt and heating drying device, but the existing equipment generally has the following problems: hot air blows continuously across the surface of the mesh belt to dry the materials on it, and the supply of hot air is uneven, resulting in uneven drying of medicinal materials; The number of conveyor belts is generally one, so that the material enters from the feeding end and is finally sent out from the discharging end. The whole process is not stirred, resulting in inconsistent drying effects between the materials pressed on the bottom layer and the materials on the surface layer. If the conveyor belt is short, it will cause drying. Incomplete; in conventional drying devices, the moisture content of the air entering the dryer is equal to the humidity content of the ambient air. When the ambient temperature is high, the moisture content is high and the material requires low-temperature drying, the application of this drying device will be limited to a certain extent; The dehumidification device of existing equipment generally has incomplete dehumidification, which leads to incomplete drying of medicinal materials and difficult control of the quality of dried products
