Description

Technical Field

[0001] This application belongs to the field of traditional Chinese medicine decoction piece drying technology, specifically relating to an online microwave and infrared combined drying equipment for traditional Chinese medicine decoction pieces. Background Technology

[0002] Drying is a crucial step in the processing of traditional Chinese medicine (TCM), directly affecting the quality, efficacy, and storage stability of TCM decoction pieces. Traditional drying processes (such as sun-drying and shade-drying) suffer from low efficiency, high energy consumption, and susceptibility to environmental influences. While modern drying technologies (such as hot air drying, vacuum freeze-drying, microwave drying, and infrared drying) have made improvements, they still differ in terms of cost, efficiency, and retention of active ingredients.

[0003] In existing technologies, if the drying equipment for Chinese herbal medicine slices is relatively tall, the process of loading the medicinal materials requires manual lifting of the container containing the materials, followed by manual pouring of the materials into the drying area of ​​the equipment. This loading method is not only inconvenient but also labor-intensive. Furthermore, some current equipment using microwave drying alone can easily cause the surface of the medicinal materials to harden, making it difficult for internal moisture to escape. Infrared drying alone may not provide sufficient heating depth and fails to achieve synergistic heating of microwave and infrared, or online monitoring of temperature and humidity during the drying process. Consequently, it is impossible to adjust the drying state of the equipment according to the dynamic changes in local temperature and moisture of the medicinal materials, thus affecting the drying quality and efficiency. Therefore, a Chinese herbal medicine slice drying equipment that combines online microwave and infrared drying is needed.

[0004] To address the above problems, this application designs an online microwave and infrared combined drying equipment for traditional Chinese medicine decoction pieces, which solves the problems of inconvenient and labor-saving feeding and difficulty in adjusting the drying state of the drying equipment according to the drying condition of the medicinal materials.

[0016] Compared with the prior art, the technical solution provided in this application has at least the following beneficial effects: This application provides an online microwave and infrared combined drying equipment for traditional Chinese medicine decoction pieces. The equipment uses a feeding drive component to control the feeding of the concave box, eliminating the need for manual lifting and making the feeding process easier and less labor-intensive.

[0020] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0022] The following reference Figures 1 to 10This application describes an online microwave and infrared combined drying device for traditional Chinese medicine decoction pieces, provided according to some embodiments.

[0023] In some embodiments, a base 1; a belt conveyor 2, installed on the upper part of the base 1; a support platform 3, fixed to the middle of the upper end of the base 1; a drying box 4, fixed to the upper end of the support platform 3; a concave rail 5, fixed to the right side of the upper end of the base 1; a feeding concave box 6, located on the left side of the concave rail 5, with the bottom of the feeding concave box 6 inclined; and a feeding drive assembly, located on the right side of the feeding concave box 6, used to drive the feeding concave box 6 to move up and down to feed materials; the feeding drive assembly includes: a lifting plate 501, slidably connected to the inner side of the concave rail 5, the feeding concave box 6 fixed to the left end of the lifting plate 501; a screw motor 502, fixed to the top of the concave rail 5; and a lifting screw 503, one end of which is fixed to the power end of the screw motor 502, and the other end of the lifting screw 503 is rotatably connected to the bottom of the concave rail 5, the lifting plate 501 and the lifting screw 503 being threadedly connected.

[0024] In this embodiment, in the initial state, the feeding concave box 6 is located at the lower part of the concave rail 5. The medicinal materials to be dried are loaded into the feeding concave box 6. The screw motor 502 is started to drive the lifting screw 503 to rotate and drive the lifting plate 501 to slide upward along the concave rail 5. The lifting plate 501 will drive the feeding concave box 6 to move upward together until the feeding concave box 6 rises to the same height as the feeding section on the right side of the belt conveyor 2. Therefore, there is no need to manually lift the feeding concave box 6 for feeding, and the feeding operation is more labor-saving.

[0025] In some embodiments, a concave guide plate 601 covers the left side of the loading concave box 6; two sets of guide drive components are provided and respectively located at the front and rear parts of the lower end of the concave guide plate 601, for driving the concave guide plate 601 to flip open and close; each guide drive component includes: a rotating shaft 602, rotatably connected to the lower left part of the loading concave box 6, and the lower right part of the concave guide plate 601 is fixed to the rotating shaft 602; a gear 603, fixedly sleeved around the rotating shaft 602; a synchronous cylinder 604, fixed to the lower end of the loading concave box 6; and a toothed plate 605, fixed to the free end of the synchronous cylinder 604, and the toothed plate 605 is slidably connected to the loading concave box 6, and the gear 603 meshes with the toothed plate 605.

[0026] In this embodiment, when the feeding concave box 6 is in place, the synchronous cylinders 604 of the two sets of guiding drive components are controlled to move synchronously. The free end of the synchronous cylinder 604 retracts, pushing the toothed plate 605 to move to the right. Since the toothed plate 605 meshes with the gear 603, it will drive the gear 603, the rotating shaft 602 and the concave guide plate 601 to rotate counterclockwise, thereby converting linear motion into rotational motion, driving the rotating shaft 602 to rotate, thereby driving the concave guide plate 601 fixed on the rotating shaft 602 to flip outward and open. The concave guide plate 601 tilts downward to form a chute. Since the bottom of the feeding concave box 6 is inclined, the medicinal materials in the feeding concave box 6 are smoothly guided to the belt of the running belt conveyor 2 by the concave guide plate 601 under the action of gravity and the inclined surface, achieving a relatively automatic feeding effect. Therefore, the whole feeding process is convenient and labor-saving.

[0027] In some embodiments, baffle plates 15 inserted into the feeding concave box 6 are fixed at both the front and rear parts of the right side of the concave guide plate 601.

[0028] During the feeding process of the concave guide plate 601 onto the belt of the belt conveyor 2, the baffle plates 15 at the front and rear of the concave guide plate 601 help prevent the medicinal materials from falling off the front and rear of the concave guide plate 601 during the feeding process, thus allowing the medicinal materials to be fed more stably onto the belt of the belt conveyor 2.

[0029] In some embodiments, the microwave generator 7 and the upper temperature and humidity sensor 701 are both fixed to the top of the drying chamber 4; the lower infrared radiator 8 and the lower temperature and humidity sensor 801 are both fixed to the middle of the upper end of the support platform 3; the side infrared radiator 9 and the side temperature and humidity sensor 901 are provided in pairs and are both fixed to the left and right ends of the inner wall of the drying chamber 4; the microwave generator 7 is a magnetron array and covers the drying area at the top of the drying chamber 4; the lower infrared radiator 8 and the lower temperature and humidity sensor 801 are both close to the bottom of the conveyor belt of the belt conveyor 2; the lower right part of the drying chamber 4 has a feed inlet 10 and the lower left part of the drying chamber 4 has a discharge outlet 11; the support platform 3 has a through-hole 12; and the conveyor belt of the belt conveyor 2 passes through the feed inlet 10, the discharge outlet 11 and the through-hole 12.

[0030] In this embodiment, when the medicinal materials are fed onto the belt conveyor 2, the belt conveyor 2 continues to operate, conveying the medicinal materials from right to left. The materials enter the drying chamber of the drying chamber 4 through the feed inlet 10. The microwave generator 7 (magnetron array) at the top of the drying chamber 4 is activated, emitting microwaves to the materials on the conveyor belt below. The microwaves penetrate the materials, causing the water molecules inside to vibrate and rub against each other at high speed, generating heat and achieving rapid heating from the inside out, effectively removing internal moisture. At the same time, the lower infrared radiator 9 located at the upper end of the support platform 3 emits infrared rays upward to heat the bottom of the materials. The two side infrared radiators 9 located on the left and right inner walls of the drying chamber 4 irradiate and heat the materials from both sides. Infrared drying mainly provides surface and middle heating, which can effectively compensate for the problem of low surface temperature that may be caused by microwave drying and make the heating more uniform.

[0031] In some embodiments, a controller 14 with a display screen is fixed to the right side of the concave rail 5. The microwave generator 7, the lower infrared radiator 8, and the side infrared radiator 9 are all connected to the controller 14 via signal. The upper temperature and humidity sensor 701, the lower temperature and humidity sensor 801, and the side temperature and humidity sensor 901 are all connected to the controller 14 via signal.

[0032] In this embodiment, temperature and humidity changes at different locations within the drying area are monitored in real time by an upper temperature and humidity sensor 701 located at the top of the drying chamber 4, a lower temperature and humidity sensor 801 located near the belt, and side temperature and humidity sensors 901 located on the left and right sides. The data is fed back to the controller 14. The controller 14's built-in control algorithm (such as a PID algorithm) analyzes the drying progress based on a preset drying process curve and real-time monitoring data, and dynamically adjusts the output power of the microwave generator 7, the lower infrared radiator 8, and the side infrared radiators 9. For example, when the material has a high moisture content in the early stages of drying, the microwave power can be appropriately increased to quickly remove internal moisture. In the middle and later stages of drying, to avoid surface overheating and hardening, the microwave power can be appropriately reduced and the infrared power increased, making the process of moisture migration and evaporation from the inside to the outside more gentle and uniform. This joint control under multi-source sensor feedback ensures stable and efficient drying quality.

[0033] In some embodiments, a receiving box 13 is provided on the upper left side of the base 1, near the lower left of the belt conveyor 2.

[0034] In this embodiment, the dried Chinese herbal medicine slices are finally delivered from the discharge port 11 at the left end by the belt conveyor 2 and fall into the receiving box 13 located at the lower left of the belt conveyor 2, thus completing the entire drying process.

[0035] The specific drying principle is as follows: First, the initial parameters of the equipment are set through the controller 14: for example, the initial power of the microwave generator 7 is set to 3-5kW, the initial power of the external radiator 8 is set to 2-4kW, the initial power of the side infrared radiator 9 is set to 1-3kW, the drying temperature setting range is 50-80℃, and the upper limit of humidity control is set to 30%RH. In the initial drying stage after the drying process starts (material moisture content > 30%): Controller 14 receives monitoring data from the upper temperature and humidity sensor 701, lower temperature and humidity sensor 801, and side temperature and humidity sensor 901. When the detected temperature is below 50℃ and the humidity is above 50%RH, controller 14 automatically increases the power of microwave generator 7 to 4-6kW to rapidly raise the internal temperature of the material. Simultaneously, the power of lower infrared radiator 8 is adjusted to 3-5kW, and the power of side infrared radiator 9 is adjusted to 2-4kW. This power combination is maintained until the material temperature reaches 60±5℃.

[0036] Mid-stage of drying (material moisture content 15%-30%): When the sensor detects that the temperature is stable within the range of 60-70℃ and the humidity drops to 30%-40%RH, the controller 14 gradually reduces the power of the microwave generator 7 to 2-4kW, maintains the power of the lower infrared radiator 8 at 3-4kW, and the power of the side infrared radiator 9 at 2-3kW, to ensure that the surface temperature of the material does not exceed 75℃ and to prevent surface hardening.

[0037] Late drying stage (material moisture content <15%): When the sensor detects that the humidity is below 20%RH, the controller 14 further adjusts the power of the microwave generator 7 to 1-2kW, the power of the lower infrared radiator 8 to 2-3kW, and the power of the side infrared radiator 9 to 1-2kW, maintaining the temperature within the range of 55-65℃ for slow drying to ensure the preservation of the active ingredients of the medicinal materials.

[0038] In summary, throughout the drying process, the controller 14 receives data from three sensors in real time: the upper temperature and humidity sensor 701, the lower temperature and humidity sensor 801, and the side temperature and humidity sensor 901. For example, it performs data comparison and power adjustment every 30 seconds. When any sensor detects that the temperature exceeds 80℃ or the humidity is below 10%RH, the device automatically reduces the heating power of the corresponding area by 20%-30% through the above methods to prevent overheating from damaging the quality of the medicinal materials.
