[0030] A further optimized solution is that the feeder includes a storage tank 13, the bottom surface of the storage tank 13 is fixedly connected to and connected with a feeding pipe 14, the bottom end of the feeding pipe 14 is fixedly connected to and connected with the nozzle 12; a spiral blade 15 is rotatably connected to the side wall of the inner cavity of the storage tank 13, the center of the spiral blade 15 is fixedly connected to a rotating shaft 16, the top of the rotating shaft 16 is rotatably connected to the top surface of the storage tank 13, and the spiral blade 15 is driven by the rotating shaft 16, so that the desulfurizer placed in the storage tank 13 can be accurately put into the nozzle 12, and then introduced into the gas distribution block 21 by blowing compressed air.

[0031] According to a further optimized solution, the guide plate 9 is tilted, and guide holes 10 are provided on opposite sides of the guide plate 9 . The guide plate 9 is connected to the conveyor belt 6 and the desulfurization cylinder 11 through the guide holes 10 .

[0032] A method for desulfurizing Chinese medicinal pieces, comprising the following steps: S1: Infiltrating medicinal materials: Introduce the medicinal materials in batches into the cavity between the water tank 1 and the conveyor, and the water tank 1 is filled with pure water. The Chinese herbal medicine pieces are stirred and infiltrated by the intermittent transmission of the conveyor.

[0033] When the Chinese herbal medicine pieces are placed in the water tank 1, they will enter the cavity formed by the water tank 1 and the lower end of the conveyor belt 6 by gravity. The baffle 8 will prevent the Chinese herbal medicine pieces from entering the bottom of the inner cavity of the water tank 1 through the gap between the conveyor belt 6 and the side wall of the water tank 1. At the same time, the conveyor belt 6 is continuously rotated under the drive of the first transmission roller 2 and the second transmission roller 3, thereby achieving the cleaning of the Chinese herbal medicine pieces and the stirring of the water in the water tank 1.

[0034] Furthermore, the water in the water tank 1 is kept at a constant temperature by a temperature control heating device, and the temperature of the pure water needs to be maintained at 40°C-60°C, which can not only ensure that the sulfur in the Chinese herbal medicines is activated and easily precipitated, but also avoid the precipitation of effective ingredients in the Chinese herbal medicines causing a decrease in efficacy.

[0035] Furthermore, the baffle 8 is detachably connected to the conveyor belt 6, so that the Chinese herbal medicines can be washed by circulating the conveyor belt 6 several times, and the baffle 8 can also be fixed to the conveyor belt 6 to realize the transportation of the Chinese herbal medicines.

[0036] S2: Desulfurization of medicinal materials: The soaked medicinal materials are introduced into the dehydration barrel 17 through the guide plate 9, and the water droplets gathered on the surface of the Chinese medicinal pieces are thrown away by the dehydration barrel 17 through the centrifugal force, and then the desulfurizer is sprayed into the feeding component to fully contaminate the Chinese medicinal pieces with the desulfurizer.

[0037] The soaked Chinese herbal medicine slices are transported to one end of the guide plate 9 by the conveyor belt 6. The guide plate 9 is tilted and penetrates the desulfurization cylinder 11 and then introduced into the dehydration barrel 17. The dehydration barrel 17 is driven to rotate by the second motor 18 to separate the accumulated water droplets attached to the surface of the Chinese herbal medicine slices. Then the rotating shaft 16 is rotated, and the spiral blade 15 is used to introduce the desulfurizer into the nozzle 12 through the feeding pipe 14. One end of the nozzle 12 introduces compressed air. The release of compressed air will drive the desulfurizer into the air inlet 23. The air inlet 23 disperses the compressed air into each air distribution pipe 22 through the air distribution block 21, and sprays it out through the air distribution channel 25. The high-speed jet of compressed air carries the desulfurizer and blows it to the Chinese herbal medicine slices arranged in the dehydration barrel 17, so as to achieve full mixing of the Chinese herbal medicine slices and the desulfurizer.

[0038] S3: Cleaning of medicinal materials: After the Chinese medicinal pieces are contaminated with the desulfurizer, they are dissolved with soaking water and react with the sulfur-containing components on the surface of the Chinese medicinal pieces. The Chinese medicinal pieces are then sucked out by the mixing component and placed in the water tank 1 for cleaning. Finally, they are rinsed with clean water for several times and then dried for use.

[0039] Furthermore, the Chinese herbal medicine pieces are fully mixed with the desulfurizer, and the desulfurizer is dissolved by the residual moisture on the surface of the Chinese herbal medicine pieces, and then reacts with the desulfurizer to neutralize the sulfur content and realize conversion. All the substances in the dehydration barrel 17 are extracted through the extraction pipe 27. Specifically, the extraction pipe 27 can be disassembled from the installation hole and penetrated into the dehydration barrel 17. The extraction pipe 27 is used to contact the filter 30 and separate from the breathable cover 26 to realize the extraction of all the Chinese herbal medicine pieces from the dehydration barrel 17. The Chinese herbal medicine pieces are rinsed with clean water. During the process, the desulfurizer filtered on the filter 30 will further react with the residual sulfur content of the Chinese herbal medicine pieces during the rinsing process, thereby improving the purification efficiency of the Chinese herbal medicine pieces.

[0040] To further optimize the solution, in step S1, the clean water needs to pass through the desulfurizing agent, which is a solid powder of sodium carbonate or sodium bicarbonate, and the particle size of which is 80 microns to 180 microns, so that it is easy to be carried by compressed air and to dissolve and mix with the Chinese herbal medicine pieces.

[0041] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
