Description

Technical Field

[0001] This application relates to the technical field of equipment for preparing Chinese herbal medicine pieces, and more specifically, to a high-efficiency low-temperature drying device for Chinese herbal medicine pieces. Background Technology

[0002] In the preparation of traditional Chinese medicine decoctions, in order to preserve the effective components of the medicinal materials and fully ensure the stability of the quality of the medicines, relevant staff often use a high-efficiency low-temperature drying device for traditional Chinese medicine decoction pieces to dry the medicines.

[0003] The prior art publication number CN213931843U provides a low-temperature drying oven for the production of Chinese herbal medicine pieces. This device, by setting a threaded screw and a movable scraper, can disperse the medicinal materials on the support plate, increase the contact area between the medicinal materials and the air, make the drying effect of the medicinal materials better, and improve the work efficiency of drying medicinal materials.

[0004] While the existing technical solutions described above can improve the drying efficiency of medicinal materials to some extent, they still have the following drawbacks: When drying medicinal materials using these solutions, the materials are always placed on a support plate with a fixed structure, and the airflow is blown from bottom to top by an intake fan. Under this method, it is difficult to ensure the uniformity of drying for medicinal materials at different heights, thus compromising the stability of the drug's quality. Therefore, we propose a high-efficiency low-temperature drying device for traditional Chinese medicine decoction pieces. Utility Model Content

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This application discloses a high-efficiency low-temperature drying device for traditional Chinese medicine decoction pieces, comprising: a processing shell 1, a conveyor belt 6 installed inside the processing shell 1, two drive rollers 3 installed inside the conveyor belt 6, the drive rollers 3 being constrained to one side of the processing shell 1 and rotatably connected thereto, a rotating mechanism installed on one side of the processing shell 1, the rotating mechanism being used to drive the drive rollers 3 through friction transmission, the drive rollers 3 through friction transmission with the conveyor belt 6, a plurality of receiving blocks 4 fixedly connected on the conveyor belt 6, a placement cage 5 detachably installed on one side of the receiving block 4, the placement cage 5 having a dense distribution of ventilation holes 501, a sealing cover 15 inserted on one side of the placement cage 5, an air distribution box 2 installed inside the processing shell 1, the air distribution box 2 having a dense distribution of multiple air blowing holes 201, a blower installed on one side of the air distribution box 2, the air outlet end of the blower communicating with the inner cavity of the air distribution box 2, and an exhaust hole 101 also being provided on the processing shell 1.

[0029] A mounting ring 12 is fixedly installed on the receiving block 4, and a connecting post 13 is fixedly connected to the end of the placement cage 5. The connecting post 13 is threadedly engaged with the mounting ring 12.

[0030] The blower equipment includes a blower 11, a filter box 16 is fixedly connected to the air outlet end of the blower 11, a top cover 14 is inserted on the filter box 16, several sets of filter membranes 17 are installed inside the filter box 16, and one side of the inner cavity of the filter box 16 is connected to the inner cavity of the air distribution box 2.

[0031] The staff evenly spreads the medicinal materials in the placement cage 5. When the medicinal materials are dried, under the action of the blower 11, the external airflow is filtered through the filter membrane 17 and enters the air distribution box 2. It is then blown onto the medicinal materials through the air blowing hole 201. During this process, the motor 18 runs, the transmission roller 3 rotates, and the conveyor belt 6 drives the placement cage 5 and the medicinal materials inside to rotate back and forth. In this way, the medicinal materials at different heights can be dried evenly, which not only improves the drying efficiency of the medicinal materials, but also fully ensures the stability of the quality of the medicinal materials.

[0032] Reference Figure 2 and Figure 3 A rotatable stirring rack 7 is provided on the sealing cover 15. A rotating mechanism is installed on one side of the stirring rack 7 to drive the stirring rack 7 to rotate.

[0033] The rotating mechanism includes a fixed toothed ring 10 installed on one side of the conveyor belt 6, a driving gear 8 sleeved and fixed on one side of the mixing frame 7, a connecting gear 9 meshing with one side of the driving gear 8, and the connecting gear 9 meshing with the fixed toothed ring 10.

[0034] During the reciprocating rotation of the placement cage 5, the gear 8 and the connecting gear 9 are driven to rotate as well. Since the connecting gear 9 meshes with the fixed gear ring 10, the turning rack 7 will rotate to turn the medicinal materials in the placement cage 5, so that the medicinal materials can come into more comprehensive contact with the airflow. In this way, the drying efficiency and uniformity of the medicinal materials are further improved.

[0035] This application enables the herbs at different heights to be dried evenly by setting up a transmission roller 3, a placement cage 5, and a conveyor belt 6. This not only improves the drying efficiency of the herbs but also ensures the stability of their quality. Furthermore, by setting up a turning rack 7 and a rotating mechanism, the herbs can be made to come into more comprehensive contact with the airflow, further improving the drying efficiency and uniformity of the herbs.

[0036] The implementation principle of the high-efficiency low-temperature drying device for traditional Chinese medicine decoction pieces in this application embodiment is as follows: When relevant personnel need to use this technical solution to perform low-temperature drying of traditional Chinese medicine decoction pieces, the personnel first evenly spread the medicinal materials in the placement cage 5. During the drying process, under the action of the blower 11, the external airflow is filtered through the filter membrane 17 and enters the air distribution box 2, and is blown onto the medicinal materials through the air blowing holes 201. During this process, the motor 18 runs, the transmission roller 3 rotates, and the conveyor belt 6 drives the placement cage 5 and the medicinal materials inside to rotate back and forth, so that the medicinal materials at different heights can be dried evenly. During this period, the drive gear 8 and the connecting gear 9 follow the rotation of the placement cage 5, and the turning rack 7 will rotate to turn the medicinal materials in the placement cage 5. After continuing for an appropriate time, the drying operation of the medicinal materials can be completed.
