Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a vacuum drying oven for processing Chinese medicinal materials. Background Technology

[0002] Chinese medicinal materials are medicinal materials used in traditional Chinese medicine treatments. They are generally various herbal raw materials. Medicinal materials can only be used after processing, and drying is the first and most important step in the processing of medicinal materials.

[0003] Current drying equipment has limited internal capacity and slow heating rate, resulting in long drying time and affecting overall drying efficiency. Furthermore, the limited space for loading and unloading materials in current vacuum drying ovens also affects the efficiency of loading and unloading. Therefore, this paper proposes a vacuum drying oven for processing Chinese medicinal materials. Utility Model Content

[0004] The technical problem this invention aims to solve is that current drying equipment has limited internal capacity and slow heating rate, resulting in long drying time and affecting overall drying efficiency. Furthermore, the limited space for loading and unloading materials in current vacuum drying boxes also affects the efficiency of loading and unloading. This invention provides a vacuum drying box for processing Chinese medicinal materials that allows for open loading and unloading space, improving loading and unloading efficiency. It also improves heating efficiency through induction heating, thereby increasing the overall drying efficiency.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a vacuum drying oven for processing Chinese medicinal materials, including a box body, an installation cavity is opened on the side wall of the box body, a coil is detachably embedded in the installation cavity, an iron plate is fixedly connected to the inner wall of the box body, the iron plate is a hollow cylindrical structure, the iron plate is located inside the coil, the box body is a high-strength and high-temperature resistant plastic shell structure, three layers of holding trays are set inside the iron plate, and a cover plate is detachably connected to the top opening of the box body, and an airtight gasket is fixed to the inner wall of the cover plate.

[0006] As a preferred technical solution of this utility model, the holding trays are detachably connected by connecting columns, the bottom sidewall of the holding trays is provided with a mesh structure, the holding trays and the box body have the same structure, and the bottom of the box body is detachably connected to a base.

[0007] As a preferred technical solution of this utility model, the base has a bottom groove inside, and a telescopic rod is detachably connected to the middle of the bottom side wall of the bottom groove. The output end of the telescopic rod extends into the iron plate and is detachably connected to the bottom side wall of the lowest holding plate.

[0008] As a preferred technical solution of this utility model, a vacuum pump is detachably connected to the bottom sidewall of one side of the bottom groove, and a steam extraction pump is detachably connected to the upper sidewall of the vacuum pump via a column. The input ends of the vacuum pump and the steam extraction pump are connected to pipes, and the pipes extend into the iron plate. The output ends of the steam extraction pump and the vacuum pump are detachably connected to pipes, and one end of the pipes extends out through the sidewall of the base.

[0009] As a preferred technical solution of this utility model, a control box is provided on one side of the box body, and a connector is fixedly connected to the side wall opposite to the box body. The side of the connector extending into the mounting cavity is electrically connected to both ends of the coil.

[0010] The present invention has the following advantages: the coil is powered by the control box, and as the coil is energized, it induces a reaction with the iron plate, thereby increasing the temperature of the iron plate itself. As the temperature of the iron plate rises, the temperature of the internal space of the iron plate rises rapidly through thermal radiation, thereby quickly reaching the drying temperature and improving the efficiency of the drying process. The telescopic rod is activated to drive the trays to rise. Since the two trays are connected by a connecting column, all trays can be driven to rise and fall synchronously at the same time. As they rise, the trays are moved from the narrow space inside the iron plate to the outside, thereby increasing the operating space and improving the convenience of picking up and putting down materials. This avoids the efficiency of loading and unloading materials being affected by the limited operating space. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] Please refer to the following: Figure 1-3This utility model discloses a vacuum drying oven for processing Chinese medicinal materials, including a box body 1. The side wall of the box body 1 has an installation cavity 13. A coil 14 is detachably embedded in the installation cavity 13. An iron plate 15 is fixedly connected to the inner wall of the box body 1. The iron plate 15 is a hollow cylindrical structure and is located inside the coil 14. The box body 1 is a high-strength and high-temperature resistant plastic shell structure. Three layers of holding trays 6 are set inside the iron plate 15. The top opening of the box body 1 is detachably connected to a cover plate 8, and an airtight gasket is fixed to the inner wall of the cover plate 8. Connecting posts 7 are detachably connected between the holding trays 6. The bottom side wall of the holding tray 6 has a mesh structure. The holding tray 6 and the box body 1 have the same structure. The bottom of the box body 1 is detachably connected to the base 2. The base 2 has a bottom groove 9 inside. The bottom side wall of the bottom groove 9 is detachably connected to the telescopic rod 10. The output end of the telescopic rod 10 extends into the iron plate 15 and is detachably connected to the bottom side wall of the bottommost holding tray 6.

[0015] The technical effect of this solution is as follows: The telescopic rod 10 is activated to drive the trays 6 to rise and fall. Because the trays 6 are interconnected by connecting columns 7, one telescopic rod 10 can drive all the trays 6 to rise and fall. During processing, all the trays 6 are pushed out of the iron plate 15 in this way, allowing for material handling in an open space. After the medicinal materials are placed, the telescopic rod 10 is lowered back into the iron plate 15, and then the coil 14 is energized. This induction rapidly heats the iron plate 15, quickly increasing the temperature inside the iron plate 15 and raising the internal temperature to the required drying temperature in a short time, thereby improving the efficiency of the drying process.

[0016] A vacuum pump 11 is detachably connected to the bottom side wall of one side of the bottom groove 9. A steam pump 12 is detachably connected to the upper side wall of the vacuum pump 11 via a column. The input ends of the vacuum pump 11 and the steam pump 12 are connected to pipes 3, and the pipes 3 extend into the iron plate 15. The output ends of the steam pump 12 and the vacuum pump 11 are detachably connected to pipes 3. One end of the pipes 3 extends out through the side wall of the base 2. A control box 4 is set on one side of the box 1. A connector 5 is fixedly connected to the side wall of the control box 4 opposite to the box 1. The side of the connector 5 extending into the mounting cavity 13 is electrically connected to both ends of the coil 14.

[0017] The technical effect of this solution is as follows: After the medicinal materials are placed, the cover plate 8 is placed on the box 1, and then the vacuum pump 11 is started to evacuate the iron plate 15 to ensure the vacuum state inside the iron plate 15. Different temperature ranges can be achieved by adjusting the power of the control box 4. According to the principle of induction heating, non-metallic parts and parts not located in the middle of the coil 14 will not be affected by heating, thus avoiding affecting the normal operation of other parts. During the heating process, the steam is extracted and discharged by the steam pump 12 to avoid affecting the drying effect.

[0018] Specifically, in use of this utility model, the holding tray 6 is first pushed out of the iron plate 15 by the telescopic rod 10, and then the medicinal materials are placed on the holding tray 6. After that, the holding tray 6 is lowered back into the iron plate 15, and then the cover plate 8 is placed on the top of the box 1. Then, the coil 14 is energized by the control box 4, and the iron plate 15 is heated rapidly by electromagnetic induction, thereby quickly raising the temperature of the internal space of the iron plate 15 and improving the efficiency of the drying process. Before processing, a vacuum is drawn by the vacuum pump 11, and during processing, steam is drawn by the steam pump 12. After drying is completed, the telescopic rod 10 is activated to push the holding tray 6 out of the iron plate 15, and then the dried medicinal materials are taken out and placed on new medicinal materials for the next round of processing.

[0019] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0020] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
