Description

Technical Field

[0001] The utility model relates to the technical field of Chinese medicinal material processing, in particular to a vacuum drying device for Chinese medicinal materials. Background Art

[0002] The essence of drying Chinese medicinal materials is the complex heat and mass coupling transfer process of Chinese medicinal materials under the action of drying media, and the moisture content of Chinese medicinal materials is reduced during the drying process to facilitate safe storage. The drying effect of Chinese medicinal materials is better in a vacuum environment. Therefore, a vacuum drying device is needed when drying Chinese medicinal materials.

[0003] Patent CN216814816U proposes a vacuum drying device for processing Chinese medicinal materials. Through the setting of a drying mechanism, through the setting of a heating seat, a connecting seat, a drying seat and a drying box, through the coordinated use of an electric slide rail and a drying seat, the distance between the drying box and the heater can be adjusted, and the Chinese medicinal materials inside the drying box can be adjusted to be close to the heater, thereby increasing the drying temperature of the Chinese medicinal materials, thereby improving the drying efficiency of the device.

[0004] In the above scheme, a sliding connection is adopted between the drying box and the heating seat to facilitate the placement and removal of the drying box. However, during the vacuum drying process, since the medicinal materials are piled up inside the drying box, the medicinal materials on the side close to the heating seat will be dried more efficiently, and the medicinal materials on the upper layer will be dried more slowly, resulting in uneven drying of the medicinal materials and lower efficiency. In addition, the technical scheme cannot conveniently take out all the drying boxes at the same time, which affects the efficiency of feeding and removing the medicinal materials.
