Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically to a medicinal material turning and drying device. Background Technology

[0002] In the processing of Chinese medicinal herbs, drying is a crucial step in ensuring quality and extending shelf life. Traditional drying methods often employ natural air-drying or static drying, which suffer from low drying efficiency, uneven heating, and susceptibility to localized mold growth or over-drying. These methods particularly affect the preservation of the active ingredients in the herbs and are difficult to meet the demands of large-scale production.

[0003] With the development of processing technology, various automated drying equipment has emerged, achieving batch drying through the installation of heating chambers and heating devices. To address the problem of uneven heating of medicinal materials, some equipment has added a turning mechanism, which mechanically agitates the materials during the drying process to improve drying uniformity. Most of the equipment's turning parts come into direct contact with the medicinal materials, which can easily cause them to break. This is especially true for fragile Chinese medicinal materials, which can lead to the loss of effective ingredients and economic losses. As a result, some valuable or fragile medicinal materials can only be turned manually, resulting in low drying efficiency for such materials. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a medicinal herb turning and drying device, which solves the problems of easy breakage of medicinal herbs, uneven drying, and inconvenient maintenance in existing medicinal herb drying equipment.

[0005] To achieve the above objectives, this utility model provides a medicinal herb turning and drying device, including a drying chamber with a heating system. Trays are evenly spaced inside the drying chamber. A chain mesh is detachably and fixedly connected between the left and right sides of the inner wall of the tray. There is a certain gap between the connection between the chain mesh and the tray and the bottom wall of the tray. When the middle part of the chain mesh hangs down naturally, it fits against the bottom wall of the tray. A turning rod is provided inside the tray and below the chain mesh. A drive component for driving the turning rod to reciprocate horizontally is provided on the tray.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Preferably, both ends of the chain mesh are in contact with the inner wall of the tray, and the bottom wall of the tray has several ventilation holes.

[0008] Preferably, the drive assembly includes a screw, a connecting block, a screw sleeve, and a support block. The bottom wall of the tray has a track groove, the connecting block passes through the track groove, and the side wall of the connecting block fits against the corresponding side wall of the track groove. The screw sleeve is fixedly installed below the connecting block, and the support block is fixedly installed on the top of the connecting block. The screw sleeve is threadedly connected to the screw. A drive motor is fixedly connected to the outside of the drying chamber, and the drive motor is used to drive the screw to rotate.

[0009] Preferably, screws are symmetrically rotatably connected to the flipping rod, and threaded holes are symmetrically opened at the top of the support block, with the bottom end of the screw extending into the threaded hole and threadedly connected to the threaded hole.

[0010] Preferably, mounting blocks are fixedly connected to both ends of the chain mesh, the top of the mounting blocks is provided with a protrusion, and the inner walls of both sides of the tray are provided with mounting grooves. Fixing blocks are fixedly connected to the inside of the mounting grooves by bolts, and the bottom of the fixing blocks is provided with grooves that match the protrusions of the mounting blocks.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The chain mesh is indirectly lifted by the flipping rod, which drives the medicinal materials to flip, avoiding direct contact between the flipping parts and the medicinal materials, effectively reducing the breakage rate of fragile medicinal materials and reducing the loss of effective ingredients; The height of the flipping rod can be precisely adjusted by the cooperation of the screw and the threaded hole, so as to achieve targeted flipping of medicinal materials of different thicknesses and textures, and further improve the adaptability of the equipment to a variety of medicinal materials. The gap design between the chain mesh and the bottom wall of the tray, as well as the ventilation hole structure of the bottom wall of the tray, ensures that the hot airflow can fully penetrate the medicinal materials, solving the problem of uneven heating in certain areas; the medicinal materials are constantly changing the heated surface during the turning process, further improving the uniformity and efficiency of drying. The chain mesh achieves detachable connection through the interlocking structure of the mounting block and the fixing block. The flipping rod is connected to the support block by screws, which facilitates quick disassembly, cleaning or replacement and reduces maintenance costs. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-4 As shown, this embodiment provides a medicinal herb turning and drying device, including a drying chamber 1 with a heating system. The heating system can adopt existing heating methods such as electric heating tubes and hot air circulation devices to provide a stable drying temperature inside the chamber. Trays 2 are evenly spaced inside the drying chamber 1. The trays 2 are used to hold the Chinese medicinal herbs to be dried. The multi-layer tray design can increase the drying capacity per batch and adapt to the needs of large-scale production.

[0016] A chain mesh 3 is detachably and fixedly connected between the left and right sides of the inner wall of tray 2. The chain mesh 3 is made of metal or high-strength, high-temperature resistant material, and its mesh size can be adjusted according to the particle size of the medicinal materials. This prevents the medicinal materials from leaking out while ensuring air permeability. There is a certain gap between the connection point of the chain mesh 3 and tray 2 (i.e., the left and right ends) and the bottom wall of tray 2. This gap can prevent the medicinal materials from accumulating at the left and right corners after repeated turning. When the middle part of the chain mesh 3 hangs down naturally, it fits against the bottom wall of tray 2, so that the medicinal materials can be evenly spread on the chain mesh 3, ensuring maximum heating area.

[0017] In summary, the improvement of this embodiment lies in the fact that the chain mesh 3 is indirectly lifted by the flipping rod 4 to drive the medicinal materials to flip, avoiding direct contact between the flipping parts and the medicinal materials, effectively reducing the breakage rate of fragile medicinal materials and reducing the loss of effective ingredients.

[0018] Based on the above, other structures also need to be disclosed in detail, such as: Both ends of the chain mesh 3 abut against the inner wall of the tray 2 to prevent the medicinal materials from leaking out from the front and rear sides of the chain mesh 3; the bottom wall of the tray 2 is provided with several ventilation holes 201, so that the hot air flow in the drying chamber 1 can penetrate the chain mesh 3 through the ventilation holes 201 and come into contact with the medicinal materials, thereby improving the heat exchange efficiency and shortening the drying time.

[0019] The drive assembly 5 includes a screw 501, a connecting block 502, a threaded sleeve 503, and a support block 504. A track groove 202 is formed in the bottom wall of the tray 2. The connecting block 502 passes through the track groove 202, and its sidewall is fitted against the corresponding sidewall of the track groove 202. The track groove 202 guides the connecting block 502, ensuring smooth movement of the flipping rod 4. The threaded sleeve 503 is fixedly installed below the connecting block 502, and the support block 504 is fixedly installed on top of the connecting block 502. The threaded sleeve 503 is threadedly connected to the screw 501. A drive motor 101 is fixedly connected to the outside of the drying chamber 1. The drive motor 101 drives the screw 501 to rotate. When the screw 501 rotates, the threaded sleeve 503 can move axially along the screw 501, thereby driving the flipping rod 4 to move synchronously through the connecting block 502.

[0020] Screws 8 are symmetrically rotatably connected to the flipping rod 4. Threaded holes 505 are symmetrically opened at the top of the support block 504. The bottom end of the screws 8 extends into the threaded holes 505 and is threadedly connected to them. By rotating the screws 8, the height of the flipping rod 4 relative to the support block 504 can be adjusted to accommodate the flipping needs of medicinal materials of different thicknesses and textures. Simultaneously, the cooperation between the screws 8 and the threaded holes 505 also enables a detachable connection between the flipping rod 4 and the support block 504, facilitating the replacement or maintenance of the flipping rod 4.

[0021] Both ends of the chain mesh 3 are fixedly connected to mounting blocks 301, and the top of the mounting blocks 301 is provided with a protrusion 302. The inner walls of both sides of the tray 2 are provided with mounting grooves 203, and fixing blocks 6 are fixedly connected to the inside of the mounting grooves 203 by bolts. The bottom end of the fixing blocks 6 is provided with a groove 7 that matches the protrusion 302 of the mounting blocks 301. Through the interlocking cooperation between the protrusion 302 and the groove 7, combined with the fixing of the fixing blocks 6 by bolts, the chain mesh 3 and the tray 2 can be quickly disassembled and assembled, which is convenient for cleaning the medicinal debris remaining on the surface of the chain mesh 3.

[0022] In summary, the workflow of this solution is as follows: Align the protrusions 302 of the mounting blocks 301 at both ends of the chain mesh 3 with the grooves 7 of the fixing blocks 6 inside the mounting grooves 203 on the inner wall of the tray 2, and press to lock them in place to secure the chain mesh 3. Adjust the height of the flipping rod 4 by rotating the screw 8 according to the thickness and texture of the medicinal materials to be dried.

[0023] The Chinese medicinal materials to be dried are evenly spread on the chain mesh 3, the door of the drying chamber 1 is closed, and the heating system and drive assembly 5 are started. The screw 501 of the drive assembly 5 moves alternately forward and reverse under the drive of the motor, and the screw sleeve 503 moves horizontally back and forth along the axis of the screw 501. Through the connecting block 502, the support block 504 and the flipping rod 4 move synchronously. When the flipping rod 4 moves horizontally below the chain mesh 3, it lifts the middle part of the chain mesh 3 so that it is separated from the bottom wall of the tray 2. The chain mesh 3 undulates, causing the medicinal materials above to flip and change position. When the flipping rod 4 is removed, the chain mesh 3 re-adheres to the bottom wall of the tray 2 under its own weight and the pressure of the medicinal materials.

[0024] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
