Description

Technical Field

[0001] This utility model belongs to the technical field of traditional Chinese medicine sterilization equipment, specifically, it relates to a steam sterilization equipment for traditional Chinese medicine raw materials. Background Technology

[0002] Steam sterilization equipment for Chinese herbal raw materials is a specialized device for high-temperature steam sterilization of Chinese herbal raw materials. It utilizes the high temperature and high pressure of saturated steam to denature the proteins, nucleic acids, and other biological macromolecules of microorganisms, thereby effectively killing bacteria, molds, spores, and other microorganisms to ensure the hygiene and safety of Chinese herbal raw materials and meet the production requirements of the pharmaceutical, food, and other industries.

[0003] The prior art discloses a high-temperature steam sterilizer for the preparation of traditional Chinese medicine (CN217187072U). An inner cabinet is installed within the inner cavity of the main cabinet via a connecting block. The inner cabinet contains a horizontal support plate, a steam pipe above the support plate, and a gas collection hood below the support plate. A multi-layer shelf is rotatably mounted on the support plate, located within the steam pipe's outlet. The lower surface of the multi-layer shelf is driven by a motor at the bottom of the cabinet. The outlet of the gas collection hood is connected to the inlet of a blower. This modular structure of the main cabinet and inner cabinet reduces heat dissipation and prevents excessive steam condensation, thus reducing sterilization efficiency and energy waste. The rotatable multi-layer shelf enhances the contact between the herbs and steam, ensuring comprehensive sterilization and reducing obstruction to steam, thereby improving sterilization efficiency. It also reduces moisture absorption by the herbs and can be used to dry them.

[0004] Research revealed that existing technologies require stacking raw materials inside rotating multi-layer shelves, which prevents the stacked materials from being evenly covered by steam during sterilization, resulting in poor sterilization. Furthermore, existing technologies use electric heating wires for additional heating and drying, which is wasteful of economic resources and fails to achieve rational utilization and processing of resources.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A steam sterilization device for traditional Chinese medicine raw materials, including

[0008] The cabinet has a door hinged to one side, an air intake pipe inside the bottom, and a fan installed on one side of the bottom.

[0009] The rotating assembly is movably installed inside the cabinet. The rotating assembly includes a storage tray, a main gear, a bracket, a driven gear, a connecting rod, and a limiting bracket.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] A steam sterilization device for traditional Chinese medicine raw materials, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the system includes a cabinet 10, with a cabinet door 13 hinged to one side of the cabinet 10. An air intake pipe 24 is installed inside the bottom of the cabinet 10, and a fan 11 is installed on one side of the bottom of the cabinet 10. A rotating assembly is also included, movably disposed within the cabinet 10. The rotating assembly includes a storage tray 17, a main gear 18, a bracket 19, a driven gear 20, a connecting rod 21, and a limiting bracket 22. The connecting rod 21 is rotatably disposed at one end of the storage tray 17. Four storage trays 17 are provided, with a pair of connecting rods 21 between every two storage trays 17. Each of the four storage trays 17 is fixedly equipped with a driven gear 20. The main gear 18 is rotatably disposed between the cabinet 10 and the bracket 19, which is rotatably disposed within the cabinet 10. The main gear 18 is driven by the four driven gears 20.

[0029] Specifically, by setting up a rotating component, during use, the Chinese herbal raw materials are evenly spread on the placement tray 17. The placement tray 17 is designed as a hollow box structure. The Chinese herbal raw materials are placed flat on the placement tray 17. The meshing between the main gear 18 and each of the driven gears 19 drives the placement tray 17 to rotate and change its position. With the limiting effect of the bracket 19 and the limiting frame 22 on the four placement trays 17, the Chinese herbal raw materials in the placement trays 17 can continuously change the position of contact with steam, thereby achieving a uniform steam coverage process and thus achieving a uniform and good sterilization effect.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, a steam inlet pipe 14 is provided on the top surface of the cabinet 10, and the steam inlet pipe 14 is connected to a steam engine. A grid 16 is fixedly installed inside the cabinet 10. A steam suction pipe 24 is fixedly installed between the cabinet 10 and the grid 16. The inlet of the steam suction pipe 24 is located above the grid 16, and the inlet of the steam suction pipe 24 communicates with the interior of the cabinet 10. Figure 1 and Figure 4 As shown, the suction pipe 24 is installed through the cabinet 10. The outlet end of the suction pipe 24 is connected to the exhaust fan 12. The exhaust fan 12 is connected to the suction pipe 24. The fan 11 is located between the cabinet 10 and the grid 16. The fan 11 is connected to the inside of the cabinet 10.

[0031] Specifically, by setting up a steam suction pipe 24 and a grid 16, with the grid 16 located directly below the rotating assembly and the steam suction pipe 24 coiled below the grid 16, the fan 11 is aligned with the steam suction pipe 24. After the exhaust fan 12 is started, excess steam in the cabinet 10 is drawn into the steam suction pipe 24. At this time, the steam extracted in the steam suction pipe 24 evaporates its residual heat. The fan 11 blows out the residual heat on the surface of the steam suction pipe 24. The residual heat combines with the airflow in the fan 11 to form hot air, which is blown onto the storage tray 17 by the fan 11 to dry the Chinese herbal raw materials inside. In this way, the residual heat of the steam can be recovered, resources can be used rationally, and costs can be reduced.

[0032] like Figure 1 , Figure 3 and Figure 5 As shown, a motor 15 is fixedly installed on one side of the outer side of the cabinet 10. Two positioning rods 25 are symmetrically arranged inside the cabinet 10. The output end of the motor 15 passes through one of the positioning rods 25 and connects to one side of the main gear 18. The two positioning rods 25 are rotatably connected to the bracket 19 and the limiting frame 22, respectively. Figure 3 As shown, both the bracket 19 and the limiting frame 22 have a cross structure. The storage tray 17 is horizontally positioned, and the two ends of the storage tray 17 are respectively fixedly connected to the driven gear 20 and the limiting post 23. The bracket 19 is rotatably connected to the driven gear 20, and the limiting frame 22 is rotatably connected to the limiting post 23. Figure 3 As shown, two connecting rods 21 are symmetrically arranged on the hypotenuse between every two storage trays 17, and each pair of storage trays 17 is limited by a corresponding pair of connecting rods 21; as Figure 3 As shown, the main gear 18 is rotatably mounted on the side of the bracket 19 away from the motor 15, and the main gear 18 meshes with and drives the four driven gears 20.

[0033] Specifically, during use, motor 15 drives main gear 18 to rotate. The rotation of main gear 18 causes driven gear 20 to passively engage. At this time, driven by driven gear 20, bracket 19 begins to rotate. Limited by connecting rod 21 and limit frame 23, the storage tray 17 remains horizontal. Simultaneously, when bracket 19 rotates, driven gear 20 only rotates in coordination with storage tray 17 and connecting rod 21 to ensure the storage tray 17 remains horizontal. At this time, with the cooperation of bracket 19 and limit frame 22... During the process of the four trays 17 rotating around each other, the steam introduced through the steam inlet pipe 14 continuously blows onto the trays 17, sterilizing the Chinese herbal raw materials on the trays 17. At the same time, excess steam is drawn into the suction pipe 24 by the exhaust fan 12, and the fan 11 blows out the residual heat accumulated on the surface of the suction pipe 24. The hot air is then blown back into the trays 17 through the grid 16. Due to the hollow design of the trays 17, the Chinese herbal raw materials are continuously dried by hot air and sterilized by steam.
