Description

Technical Field

[0001] This utility model belongs to the field of traditional Chinese medicine decoction piece processing technology, and in particular relates to a multifunctional traditional Chinese medicine decoction piece processing device. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces refer to raw medicinal materials that have undergone processing according to TCM theories and methods, and are ready for direct use in TCM clinical practice. This concept indicates that there is no absolute boundary between raw medicinal materials and decoction pieces; decoction pieces include some sliced ​​medicinal materials processed at their place of origin, whole medicinal materials, and those that have undergone cutting or roasting. The processing techniques for decoction pieces represent the core of traditional Chinese medicine manufacturing technology, originating and continuously accumulating and developing through long-term medical practice throughout history. Generally, processing involves methods such as preparation, water treatment, fire treatment, and combined water and fire treatment. Processing is a necessary step before the medicine is used or formulated into various dosage forms, including general preparation of raw materials and special treatment of some materials. The fire treatment of decoction pieces involves heating and drying.

[0003] According to the search, application (publication) number CN214792322U discloses a processing device for traditional Chinese medicine decoction pieces, which includes a processing tank, a stirring motor bolted to the center of the outer wall of the top of the processing tank, a stirring shaft bolted to the output end of the stirring motor, stirring blades of equal distance distributed on the outer wall of the stirring shaft, connecting rods welded to the outer walls on both sides of the stirring shaft, and a scraper welded to the other end of the connecting rod away from the stirring shaft, and the scraper is in contact with the inner wall of the processing tank. The device has the following technical features: when the stirring motor drives the stirring shaft, stirring blades, connecting rods and scraper to rotate, it can stir the traditional Chinese medicine decoction pieces, so that the traditional Chinese medicine decoction pieces can flow and fully contact with the hot air, thereby improving the drying efficiency; the motor drives the rotating plate to rotate, and when the rotating plate coincides with the through groove on the baffle, it will discharge the material, which solves the problem of excessive material being difficult to screen at one time; the vibrating motor can vibrate the sieve plate, which can screen the residue and traditional Chinese medicine decoction pieces.

[0004] However, the following defects still exist in actual use: First, the hot air flows horizontally, which causes the slices in the "feeding seat" to not be effectively dried; second, the rotation direction of the "stirring blades" cannot turn the slices up and down in the "feeding seat", which will result in uneven drying of the slices.

[0005] To address the aforementioned issues, this application proposes a multifunctional device for processing Chinese herbal medicine slices. Utility Model Content

[0006] The purpose of this invention is to provide a multifunctional device for processing Chinese herbal medicine slices, which solves the problem of uneven drying.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a multifunctional Chinese herbal medicine processing device, comprising a processing tank, an inner feeding seat for holding the medicinal slices on a drying station, a hot air blower for providing drying hot airflow on the side of the processing tank, a feeding mechanism for feeding the medicinal slices, the feeding mechanism being installed at the bottom opening of the feeding seat, the feeding seat being funnel-shaped and having a sieve for allowing powder to pass through, a heating pipe assembly installed inside the processing tank and located below the feeding seat, the heating pipe assembly directing the hot airflow from the hot air blower upward through the sieve and drying the medicinal slices from bottom to top; a horizontally arranged and rotatably installed stirring rod inside the processing tank, the stirring rod being located above the feeding seat, a stirring motor being fixed to the outside of the processing tank via a mounting base and the output end being fixed to the stirring rod, the stirring rod being driven by the stirring motor to stir the medicinal slices up and down; and a preparation hopper communicating with the upper opening of the processing tank, the outer wall of the preparation hopper having a guide hood for preheating the internal medicinal slices using the dried hot airflow.

[0009] Furthermore, the heating pipe assembly includes a circumferentially closed main pipe, with interconnected straight pipes fixedly provided inside the main pipe, and a connecting pipe connected to a hot air blower fixedly connected to one side of the main pipe.

[0010] Furthermore, the straight tubes are a number of tubes evenly distributed around the circumference, and the straight tubes are inclined downwards with an opening at the bottom.

[0011] Furthermore, the stirring rod includes a stirring shaft that is fixed to and rotatably connected to the output end of the stirring motor inside the processing tank. Several material-turning plates are fixed on the stirring shaft. The material-turning plates have a "V" shaped cross section, and the opening of the "V" shape faces the driving direction of the stirring motor.

[0012] Furthermore, a feeding mechanism is also provided at the connection between the bottom opening of the preparation hopper and the processing tank, through which the medicinal slices are intercepted inside the preparation hopper or lowered into the processing tank.

[0013] Furthermore, the inner side of the flow guide is open and fits against the material preparation hopper to form an airflow channel, and the bottom of the flow guide has several circumferentially distributed connection holes.

[0014] Furthermore, a flow guide ring is fixedly connected to the top of the inner side of the processing tank, and a through hole communicating with the connecting hole is provided between the top of the flow guide ring and the top of the processing tank.

[0015] This utility model has the following beneficial effects:

[0016] This utility model sets a screen in the feeding seat and places the heating pipe assembly below the screen. The heat from the hot air blower can flow from bottom to top through the heating pipe assembly, thereby improving the drying uniformity. The presence of the screen can also screen out the powder generated by stirring in time.

[0017] This utility model sets the stirring rod to be placed horizontally, and sets a turning plate on the stirring rod. After the stirring motor rotates, the inner side of the turning plate stirs the beverage slices on the feeding seat up and down, so as to avoid uneven drying between the upper and lower layers. The shape of the turning plate can fully move the beverage slices.

[0018] This invention features a connected material preparation hopper at the top of the processing tank. The material preparation hopper can prepare materials during the drying process inside the processing tank, enabling rapid replenishment and improved efficiency. Simultaneously, the guide hood outside the material preparation hopper and the guide ring inside the processing tank can direct the heat from the drying of the leaf slices inside the processing tank to the outer wall of the material preparation hopper, thereby preheating the prepared slices in the material preparation hopper. This design offers the advantages of high heat utilization and improved drying efficiency.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] 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.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figure 1-7As shown, this utility model is a multifunctional Chinese herbal medicine processing device, including a processing tank 1, a feeding seat 2 for carrying the medicinal slices on the drying station fixed inside the processing tank 1, a hot air blower 3 for providing drying hot airflow on the side of the processing tank 1, and a feeding mechanism 8 for feeding the medicinal slices. The feeding mechanism 8 is installed at the bottom opening of the feeding seat 2. The feeding seat 2 is funnel-shaped and has a screen 21 that allows powder to pass through. It also includes a heating pipe assembly 4 installed inside the processing tank 1 and located below the feeding seat 2. The hot airflow from the hot air blower 3 is passed upward through the screen 21 through the heating pipe assembly 4 and the medicinal slices are dried from bottom to top. By setting the screen in the feeding seat and placing the heating pipe assembly below the screen, the heat generated by the hot air blower can be realized to flow from bottom to top. This design not only ensures uniform drying of the medicinal slices but also allows for the immediate sieving of powder generated during the stirring process, thereby improving drying efficiency and product quality. A horizontally positioned and rotatably mounted stirring rod 5 is installed inside the processing tank 1, above the feeding seat 2. A stirring motor 6 is fixed to the outside of the processing tank 1 via a mounting base, with its output end fixed to the stirring rod 5. Driven by the stirring motor 6, the stirring rod 5 stirs the medicinal slices up and down. While the stirring motor rotates, the stirring rod 5 can also stir the medicinal slices on the feeding seat up and down via the inner side of the tilting plate. This design effectively avoids uneven drying of the upper and lower layers of medicinal slices, ensuring uniform heating of the entire medicinal slice during the drying process. A preparation hopper 7, connected to the upper opening of the processing tank 1, has an outer wall equipped with a guide hood 9 that uses the hot airflow after drying to preheat the internal medicinal slices. Utilizing the heat after drying to preheat the prepared medicinal slices not only improves heat utilization but also enhances drying efficiency to a certain extent.

[0033] The heating pipe assembly 4 includes a circumferentially closed main pipe 41, with an interconnected straight pipe 42 fixed inside the main pipe 41, and a connecting pipe 43 connected to the hot air blower 3 fixed on one side of the main pipe 41. In this embodiment, the heating pipe assembly 4 cooperates with the screen 21 to improve the drying effect and uniformity without affecting the stirring and powder sieving.

[0034] Among them, the straight pipes 42 are several evenly distributed around the circumference. The straight pipes 42 are inclined downward and have an opening at the bottom. In this embodiment, by setting them downward, the powder of the medicinal slices can be prevented from entering the interior of the heating pipe group 4 while hot air is being released.

[0035] The stirring rod 5 includes a stirring shaft 51 that is fixed to the output end of the stirring motor 6 and rotatably connected inside the processing tank 1. Several turning plates 52 are fixed on the stirring shaft 51. The turning plates 52 have a "V" shaped cross section, and the opening of the "V" shape faces the driving direction of the stirring motor 6. In this embodiment, the "V" shaped design can drive the medicinal slices to turn more during rotation, so that the upper and lower medicinal slices are more fully mixed, thereby ensuring the uniformity of drying.

[0036] The bottom opening of the preparation hopper 7 is also provided with a feeding mechanism 8 at the connection between it and the processing tank 1. The feeding mechanism 8 intercepts the medicinal slices inside the preparation hopper 7 or lowers them into the processing tank 1. In this embodiment, the feeding mechanism 8 can be a component of the patent reference number (8-14), or it can be other devices, mechanisms, valves, etc. that have opening and closing functions.

[0037] The inner side of the flow guide hood 9 is open and fits against the material preparation hopper 7 to form an airflow channel. The bottom of the flow guide hood 9 has several circumferentially distributed connection holes 91. In this embodiment, the inner side of the airflow channel is formed by the outer wall of the material preparation hopper 7. When the airflow passes through, the heat will be transferred to the internal slices of the material preparation hopper 7 through energy conduction to heat them and improve the drying efficiency.

[0038] In this embodiment, a guide ring 10 is fixedly connected to the top of the inner side of the processing tank 1. A through hole communicating with the connecting hole 91 is provided between the top of the guide ring 10 and the top of the processing tank 1. In this embodiment, the lower end of the guide ring 10 has a large opening, which can concentrate the hot air to the guide shroud 9. The through hole on the guide ring 10 and the processing tank 1 are of the same size as the connecting hole 91 and are interconnected.

[0039] Understandably, this invention can achieve a bottom-up flow of hot air without affecting drying and powder sieving, thus enabling the medicinal slices to dry more evenly. Secondly, the horizontal stirring rod can stir the medicinal slices up and down, ensuring the drying effect while improving the drying uniformity. Finally, the heat after drying is used to preheat the prepared medicinal slices, resulting in high heat energy utilization and improving the drying efficiency to a certain extent.

[0040] A specific application of this embodiment is as follows: the medicinal slices are put into the preparation hopper 7, the feeding mechanism 8 at the lower end of the preparation hopper 7 is opened to let the medicinal slices flow into the feeding seat 2, the feeding mechanism 8 on the preparation hopper 7 is closed, and more medicinal slices to be dried are added to the preparation hopper 7; when the medicinal slices are on the feeding seat 2 inside the processing tank 1, the hot air blower 3 delivers hot air to the heating pipe group 4. The hot air flows through the connecting pipe 43 and the main pipe 41 and then flows out from the straight pipe 42. At this time, the hot air passes upward through the screen 21 and heats and dries the medicinal slices on the feeding seat 2 from bottom to top. After drying, the hot air is guided by the guide ring 10 to the guide hood 9. Under the action of the guide hood 9, the hot air flows along the outer wall of the preparation hopper 7. At this time, it can preheat the medicinal slices to be dried inside the preparation hopper 7.
