Abstract

The invention relates to a belt dryer, which comprises a frame. One end of the frame is provided with a slope conveyor belt for feeding materials. A support is provided outside the frame. A hot blast stove is installed on the support. The hot blast stove is respectively connected with The heat burner and the high-pressure fan used to blow air into the hot blast stove. There are several air outlets for exhausting air on the side wall of the frame. There are at least two layers of air outlets in the frame along its vertical direction. The transmission platform, the transmission platform includes a conveyor belt and a transmission structure that drives the conveyor belt. The transmission direction between adjacent transmission platforms is opposite. The bottom transmission platform protrudes from the end of the frame away from the slope conveyor belt, and is installed in the interlayer of each layer of conveyor belt. There is an exhaust box with a hollow inside. There are multiple exhaust holes on the top of the exhaust box. There is an air inlet connected to the exhaust box on the frame. The air inlet is connected to the hot blast stove through a hot air adjustment mechanism. . The hot air distribution of the invention is more uniform, and the medicinal material drying effect is better.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine drying equipment, in particular to a belt dryer. Background technique [0002] Traditional Chinese medicinal materials refer to medicinal materials produced in areas with certain natural conditions and ecological environment, which are picked and processed for use in the treatment of patients' diseases. In the processing of Chinese medicinal materials, the most important step is drying, which can effectively remove the water in Chinese medicinal materials, retain their medicinal activity, and improve their storage durability. At present, the drying equipment used in the processing of Chinese herbal pieces is a small oven. The basic principle is to use steam or electricity as a heat source, generate heat from a steam radiator or an electric heating element, and use a fan for convective heat exchange to dry the material. Heat transfer, so as to realize the drying of medicinal m...
