Description

Technical Field

[0001] The utility model relates to the technical field of Chinese medicine slice drying machines, in particular to a net-belt drying machine used for processing Chinese medicine slices. Background Art

[0002] Chinese herbal medicine slices are Chinese herbal medicines that have been processed and prepared according to the theories and methods of traditional Chinese medicine and can be directly used in clinical Chinese medicine. When processing Chinese herbal medicine slices, in order to preserve them for a long time, they usually need to be dried. The drying operation is usually carried out in a corresponding dryer. There are many types of dryers on the market. Some dryers are mesh belt dryers. This type of mesh belt dryer is equipped with a mesh conveyor belt. The Chinese herbal medicine slices are placed on the mesh conveyor belt and then transported to the corresponding drying process for drying. After drying, the mesh conveyor belt continues to rotate to transport the dried Chinese herbal medicine slices outward, saving manpower without the need for repeated loading and unloading by humans.

[0003] However, this type of mesh belt dryer is prone to produce debris during the drying process because it uses a mesh conveyor belt. At this time, the debris directly falls down into the equipment through the through holes in the mesh conveyor belt, making it difficult to clean up. The presence of debris may also affect the normal operation of the equipment, causing inconvenience to the user. In view of this, we propose a mesh belt dryer for processing Chinese herbal medicine slices. Utility Model Content
