Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine decoction piece processing technology, and in particular to a microwave-assisted heating device for processing traditional Chinese medicine decoction pieces. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces are processed medicinal herbs that can be directly used in TCM clinical practice. These include sliced ​​herbs processed at the place of origin, whole medicinal herbs, and herbs that have undergone cutting and processing. During the production and processing of TCM decoction pieces, the sliced ​​herbs need to be dried. Microwave drying and heating devices are widely used in the field of TCM drying. A microwave generator produces microwaves, which are transmitted to the drying chamber through a waveguide system. The microwaves penetrate the medicinal material, causing water molecules to vibrate and generate heat through friction, thus achieving internal heating. This heating and drying method can preserve the medicinal properties of TCM decoction pieces to the greatest extent.

[0003] The operation method of microwave drying heating device for drying Chinese medicine is as follows: the medicinal slices are manually poured onto the head of the conveyor belt of the device, and then the workers use their hands to spread the medicinal slices evenly to avoid the medicinal slices piling up and affecting the drying effect. However, this manual spreading method is labor-intensive. Secondly, the medicinal slices are at a high temperature after drying, which makes it inconvenient to package them immediately.

[0004] Therefore, this utility model proposes a microwave-assisted heating device for processing Chinese medicinal herbs to address the above-mentioned shortcomings. Utility Model Content

[0026] 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.

[0027] Reference Figures 1-4 An embodiment of this utility model provides a microwave-assisted heating device for processing Chinese medicinal herbs, comprising a support 1, a conveyor belt 3 installed inside the top of the support 1, a first top cover 2 and a second top cover 7 fixed on both sides of the top of the support 1 respectively, an inlet 21 and an outlet 22 respectively provided on both sides of the bottom of the first top cover 2, a material leveling component 4 installed on the top of the support 1 near the inlet 21, a microwave generator 5 installed on the inner top wall of the first top cover 2, a coil 8 horizontally fixed inside the second top cover 7, a cold water component 9 installed on the lower surface of the support 1 and connected to the coil 8, and a second fan 10 penetrating and fixedly connected to the top wall of the second top cover 7.

[0028] In this embodiment, the conveyor belt 3 is driven by a motor outside the support 1. The specific working principle is the same as that of the existing microwave dryer, which mainly uses the conveyor belt 3 to transport the medicinal slices.

[0029] The material leveling assembly 4 includes a gantry frame 41 fixed to the top of the support 1. The gantry frame 41 has a U-shaped plate 42 with the opening facing downward inside. A brush roller 43 is rotatably connected inside the U-shaped plate 42, and a motor 44 is fixed to the outer wall of the U-shaped plate 42. The output end of the motor 44 is fixedly connected to the brush roller 43.

[0030] After the motor 44 is started and drives the brush roller 43 to rotate, when a piece of medicinal drink passes under the brush roller 43, the bristles on the surface of the brush roller 43 will smooth out the accumulated medicinal drink pieces, thus eliminating the need for manual smoothing. In this embodiment, the motor 44 is a geared motor, which makes the brush roller 43 rotate slowly, avoiding the brush roller 43 rotating too fast and sweeping the medicinal drink pieces away.

[0031] A guide rod 45 is fixed on the upper surface of the U-shaped plate 42. The guide rod 45 passes through the gantry frame 41 and is slidably connected to the gantry frame 41. A screw rod 46 is connected through the top wall of the gantry frame 41 and rotated by a thread. The bottom end of the screw rod 46 is rotatably connected to the upper surface of the U-shaped plate 42 by a bearing. A handle is fixedly connected to the top end of the screw rod 46.

[0032] When processing different types of medicinal slices, since the thickness and size of the medicinal slices are different, it is necessary to adjust the height of the brush roller 43 according to the size of the medicinal slices. At this time, the height of the brush roller 43 can be adjusted by turning the screw 46 with the handle, which drives the U-shaped plate 42 to rise or fall.

[0033] The first top cover 2 has an exhaust port 23 and an air inlet 24 on both sides of the middle part. The exhaust port 23 is located on the side close to the material leveling component 4. The first fan 6 is fixed on the outer wall of the first top cover 2 near the air inlet 24.

[0034] By activating the first fan 6, external air can be blown into the first top cover 2 from the air inlet 24. The air inside the first top cover 2 carries away the moisture from the drying of the medicinal slices and is discharged from the exhaust port 23.

[0035] The cold water assembly 9 includes a water tank 91 fixed to the lower surface of the bracket 1. A pump body 92 is fixed to the outer wall of the water tank 91. A water inlet pipe 93 is fixedly connected between the water inlet end of the pump body 92 and the water tank 91. The two ends of the coil 8 are respectively connected to the water outlet end of the pump body 92 and the water tank 91.

[0036] After the pump body 92 is started, water is drawn out of the water tank 91 through the water pipe 93 and then discharged into the coil 8 through the pump body 92. The second fan 10 can then blow the low temperature on the surface of the coil 8 onto the medicinal slices to cool them down. Subsequently, the water in the coil 8 flows back to the water tank 91 from the other end.

[0037] A semiconductor cooling chip 94 is fixedly connected to the lower surface of the water tank 91. Several metal plates 95 are fixed to the cooling side of the upper surface of the semiconductor cooling chip 94, and the metal plates 95 extend through the bottom wall of the water tank 91 into the interior of the water tank 91. The metal plates 95 are sealed to the bottom wall of the water tank 91. Several heat dissipation plates 96 are fixed to the heat dissipation side of the lower surface of the semiconductor cooling chip 94.

[0038] The semiconductor cooling chip 94 can cool the metal plate 95, which in turn cools the water in the water tank 91. The heat sink 96 dissipates heat from the semiconductor cooling chip 94, ensuring that the semiconductor cooling chip 94 can work normally.

[0039] Working principle: The system starts with motor 44, microwave generator 5, first fan 6, second fan 10, pump body 92, and semiconductor cooling chip 94. Motor 44 drives brush roller 43 to rotate, and semiconductor cooling chip 94 cools the water in water tank 91. Driven by pump body 92, the water in water tank 91 is circulated into coil 8. At this time, Chinese herbal medicine slices are placed on the conveyor belt 3 near the leveling component 4. The Chinese herbal medicine slices are smoothed as they pass under brush roller 43, ensuring that they are evenly spread on the surface of conveyor belt 3. After entering the first top cover 2 through inlet 21, the Chinese herbal medicine slices are dried by microwave generator 5. The moisture generated during drying is blown out through exhaust port 23 by first fan 6. Subsequently, the Chinese herbal medicine slices are discharged from outlet 22 and enter the second top cover 7. Second fan 10 blows the low temperature of the surface of coil 8 onto the Chinese herbal medicine slices, achieving rapid cooling of the Chinese herbal medicine slices, which is beneficial for subsequent packaging.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
