Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically a drying device with an automatic flipping function. Background Technology

[0002] Traditional Chinese medicine (TCM) materials refer to natural medicines and their processed products used to prevent and treat diseases or regulate bodily functions under the guidance of TCM theory. The processing of TCM materials is a traditional and complex technique, which is the key step in transforming TCM materials into clinically usable materials or further into TCM preparations.

[0003] Traditional Chinese medicinal herbs usually contain a lot of moisture after being cut. If they are not dried, they are prone to microbial growth during storage. Drying equipment can remove the moisture from the herbs, reducing the humidity required for microbial growth. Drying equipment is a device that uses heat energy such as electric heating, steam heating, or hot air heating to remove moisture from Chinese medicinal herbs.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. Most drying equipment requires manual turning of medicinal materials, which not only increases labor intensity, but also makes it difficult to ensure the timeliness and uniformity of each turn, thus affecting the stability of drying quality; 2. Some existing drying equipment does not have an effective design for the collection and discharge of moisture during the drying process, and the accumulation of moisture may drip onto the medicinal materials, affecting the drying effect.

The baking dish and the lid are connected by the pull buckle and the limit block, and the part of the baking dish and the lid that are in contact with each other is covered with high temperature resistant silicone.

[0009] More preferably, the heating module is located above the baking dish, and the length of the heating module is greater than the length of the guide rail. The fans are arranged in pairs, one above the other, adjacent to both ends of the transmission assembly. At the same time, the inner wall of the baking oven has circular through holes for installing filter plates at the positions of the fans.

The bottom of the discharge port is a cone shape that is wider at the top and narrower at the bottom, and a gate valve is provided at the discharge port.

[0012] More preferably, the sprocket assembly is provided in two sets and is distributed in parallel at the same horizontal position. The sprocket assembly consists of two sprockets and a chain that surrounds and meshes with the two sprockets. The sprockets at corresponding positions in each set of sprocket assemblies are coaxially connected and rotate between the guide rails.

[0013] More preferably, the connecting frame is connected to the chain pin of the sprocket assembly, and the baking dishes are evenly distributed above the chain through the connecting frame and are rotatably connected to the chain.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a drying device with automatic flipping function, including a drying box 1 and a raw material box 2. The raw material box 2 is fixedly connected to one end of the top of the drying box 1. A heating module 3 is fixedly connected to the inner top wall of the drying box 1. Fans 4 are fixedly connected to both ends of the inner wall of the drying box 1. A transmission component 5 is slidably connected to the inner bottom wall of the drying box 1. A baking dish 6 is rotatably connected to the outer wall of the transmission component 5.

[0026] The top of the raw material box 2 is provided with a feed inlet 201, the bottom of the raw material box 2 is provided with a discharge outlet 202, and the inside of the raw material box 2 is rotatably connected with a scraper assembly 203.

[0027] The transmission assembly 5 consists of a stand 501 and a guide rail 502. The stand 501 is slidably connected to a groove in the bottom wall of the baking oven 1 via rollers at the bottom. The guide rail 502 is fixed to the top of the stand 501 and forms an integral connection with it. A sprocket assembly 503 is rotatably connected between the guide rails 502.

[0028] The top of the baking dish 6 is rotatably connected to a top cover 601, the bottom of the baking dish 6 is fixedly connected to a drain rack 602, the inside of the baking dish 6 is inserted and connected to a grill rack 603, and the bottom four corners of the drain rack 602 are fixedly connected to connecting brackets 604. The outer wall of the top cover 601 is connected to a pull buckle 605 by bolts, and the outer wall of the baking dish 6 is connected to a limit block 606 by bolts at the corresponding positions of the pull buckle 605. The baking dish 6 and the top cover 601 are engaged and connected by the pull buckle 605 and the limit block 606, and the part of the baking dish 6 and the top cover 601 that are in contact with each other is covered with high temperature resistant silicone.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, the heating module 3 is located above the baking dish 6, and the length of the heating module 3 is greater than the length of the guide rail 502. The fans 4 are arranged in pairs, one above the other, adjacent to both ends of the transmission component 5. At the same time, the inner wall of the drying chamber 1 has circular through holes for installing filter plates corresponding to the positions of the fans 4. The length of the heating module 3 is greater than that of the guide rail 502, which means that the heating range can completely cover the running trajectory of the baking dish 6 on the guide rail 502, avoiding heating "dead corners" during the movement of the baking dish 6, so that the Chinese medicinal materials are heated evenly throughout the drying process, ensuring the consistency of drying quality. The layout of the fans 4 can form a three-dimensional airflow circulation mode. The two airflows converge around the baking dish 6, so that the hot air flows quickly and fully in the drying chamber 1. Compared with a single fan 4 or equipment with an unreasonable fan 4 layout, it can more quickly remove the moisture evaporated from the Chinese medicinal materials and accelerate the drying process. The presence of the filter plate can prevent dust and other impurities from entering the fan 4, reducing the probability of fan blade wear, blockage and other failures.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the top of the inlet 201 is trapezoidal in shape, wider at the top and narrower at the bottom. The center point of the inlet 201 and the axis of the scraping assembly 203 are located on the same vertical center line. The top of the scraping assembly 203 is conical. The larger opening of the inlet 201 provides a wider receiving space, facilitating the smooth introduction of medicinal herb raw materials into the raw material box 2 by external conveying equipment. The fact that the center point of the inlet 201 and the axis of the scraping assembly 203 are on the same vertical center line ensures that the raw materials are evenly distributed within the scraping assembly 203 after entering the raw material box 2. Within the range, the conical top of the scraper assembly 203 can evenly disperse the raw material piled on it to the surrounding area, avoiding raw material accumulation, and then push it to the discharge port 202 by the scraper. This process reduces the residue of raw material in the box and improves the raw material utilization rate. A stable raw material supply can ensure that the discharge port 202 discharges continuously and evenly, avoiding the problem of discharge interruption or uneven discharge caused by insufficient or uneven raw material supply, and improving the working efficiency of the entire drying equipment. This stable raw material supply can ensure that the discharge port 202 discharges continuously and evenly.

[0031] In this embodiment, as Figure 3 As shown, scrapers are distributed at equal angles on the outer wall of the scraping assembly 203. One side of the scraper is in contact with the bottom wall of the raw material box 2. The scrapers are rotated by a servo motor located inside the raw material box 2 corresponding to the scraping assembly 203. The discharge port 202 is located at the bottom edge of the raw material box 2 and is within the area rotated by the scraper. The bottom of the discharge port 202 is tapered, wider at the top and narrower at the bottom, and a gate valve is installed at the discharge port 202. With the gate valve at the discharge port 202, the operator can flexibly control the discharge speed and discharge volume according to actual needs, such as the filling volume of the baking rack 603. This precise control not only ensures the smooth progress of the subsequent drying process but also avoids efficiency reduction or raw material waste caused by excessive or insufficient discharge.

[0032] In this embodiment, as Figure 4 As shown, there are two sets of sprocket assemblies 503, which are distributed in parallel at the same horizontal position. Each sprocket assembly 503 consists of two sprockets and a chain that surrounds and meshes with the two sprockets. The sprockets at corresponding positions in each set of sprocket assemblies 503 are coaxially connected and rotate between the guide rails 502. During operation, the two sets of sprocket assemblies 503 work simultaneously, thereby improving the stability and reliability of the entire transmission system, making the transmission and flipping of the baking dish 6 more stable, and thus ensuring the continuity of the drying process.

[0033] In this embodiment, as Figure 4 and Figure 5As shown, the connecting frame 604 is connected to the chain pin of the sprocket assembly 503, and the baking dishes 6 are evenly distributed above the chain through the connecting frame 604 and are rotatably connected to the chain. The baking dishes 6 form a transmission structure through the sprocket assembly 503. At the same time, rollers are rotatably connected to the outer wall of the connecting frame 604, and the surface of the guide rail 502 on the side corresponding to the connecting frame 604 is opened in an annular shape, which is used to slide the rollers. The annular groove provides precise guidance for the rollers, so that the connecting frame 604 and the baking dishes 6 can move precisely according to the trajectory set by the guide rail 502, which further enhances the stability and accuracy of the transmission and avoids the baking dishes 6 from deviating during the movement, thus affecting the drying effect.

[0034] In this embodiment, as Figure 4 and Figure 5 As shown, the bottom and sides of the grill rack 603 have a mesh-like microporous structure, and the bottom and four sides of the baking dish 6 have square through holes. The baking dish 6 and the drip rack 602 are integrally connected. The drip rack 602 has a concave cavity inside, and a strip-shaped through hole on one side. The mesh-like microporous structure on the bottom and sides of the grill rack 603, combined with the square through holes on the bottom and four sides of the baking dish 6, greatly increases the contact area between the hot airflow and the Chinese medicinal materials. The hot airflow can pass through the grill rack 603 and the baking dish 6 from all directions, roasting the Chinese medicinal materials from all angles, making the Chinese medicinal materials more evenly heated and evaporating more moisture. The drying process is rapid and comprehensive, effectively shortening drying time and improving drying efficiency. The integrated connection between the baking dish 6 and the drain rack 602, along with the concave cavity inside the drain rack 602, constitutes an effective moisture collection system. This prevents moisture evaporated from the medicinal materials from dripping back onto them, thus preventing poor drying results or localized dampness and mold growth due to moisture accumulation. The strip-shaped through-hole on one side of the drain rack 602 allows the moisture collected in the concave cavity to be drained in time when the baking dish 6 is flipped to a specific angle, maintaining a relatively dry environment inside the baking dish 6. This facilitates continuous evaporation of moisture from the medicinal materials, further improving drying efficiency.

[0035] The usage and advantages of this utility model: This drying equipment with automatic flipping function operates as follows:

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, firstly, the raw materials of Chinese medicinal herbs to be processed are fed into the raw material box 2 through the inlet 201 using an external conveying device. The top of the inlet 201 is trapezoidal in shape, wider at the top and narrower at the bottom, providing ample receiving space for easy loading of raw materials. Before the baking process, the protective door panel on the outside of the baking oven 1 is opened. Using the handle on the surface of the stand 501, the transmission component 5 is pulled out from the slide groove on the bottom wall of the baking oven 1, so that one of the baking dishes 6 is directly below the discharge port 202. The spring-loaded pull buckle 605 is peeled off from the surface of the limiting block 606, and the top cover 601 is flipped over to expose the baking rack 603. The gate valve of the discharge port 202 is opened. Since the scraping component 203 inside the raw material box 2 rotates under the drive of the servo motor, its outer wall is equiangularly distributed and one side is aligned with the material. The scraper attached to the bottom wall of the material box 2 rotates, evenly channeling the material from the material box 2 into the pipe at the discharge port 202, and then into the baking rack 603 below. Based on the filling amount in the baking rack 603, the operator selectively closes the gate valve to precisely control the filling amount. After filling one set of baking racks 603, the top cover 601 is placed back on the baking dish 6, and the two are secured together using the pull buckle 605 and the limiting block 606. The high-temperature resistant silicone covering the contact area between the baking dish 6 and the top cover 601, along with the elastic pull buckle 605, effectively enhances the tightness of the connection, preventing material leakage when the baking dish 6 is flipped. The servo motor of the high-temperature resistant protective shell installed on one side of the transmission component 5 rotates, driving the... A set of sprockets rotates, driving the connecting frame 604 via a chain, thereby driving the roasting dish 6. Following this transmission method, the roasting rack 603 inside the roasting dish 6 below the discharge port 202 is filled with the raw materials to be processed. After all the medicinal materials are added, the transmission assembly 5 is pushed back into the drying oven 1, and the protective door panel on the outside of the drying oven 1 is closed. Based on the characteristics of the medicinal materials to be processed, the temperature of the heating module 3 is set by the external control unit of the drying oven 1. After the heating module 3 is turned on, the hot air, being less dense than cold air, undergoes natural convection and begins to slowly diffuse downwards. Simultaneously, the fans 4 at both ends of the inner wall of the drying oven 1 are activated. The fans 4, arranged in pairs and distributed vertically, blow air towards the central area of ​​the drying oven 1. These mixed air particles... Driven continuously by the fan 4, the airflow shuttles between the baking dishes 6. The perforated structure on the surface of the baking dishes 6 and the rack 603 ensures full contact between the airflow and the medicinal materials, making the medicinal materials evenly heated and allowing the moisture to evaporate quickly and completely. The concave cavity inside the drain rack 602 collects the moisture evaporated from the medicinal materials, preventing this moisture from dripping back onto the medicinal materials and affecting the drying effect. When the baking dishes 6 are driven to the edge and rotated by the sprocket assembly 503, this water can be discharged from the strip-shaped slots on the surface of the drain rack 602. As the roasting progresses, the baking dishes 6 move continuously under the drive of the chain and automatically rotate during the movement. This rotating action flips the medicinal materials that were originally at the bottom of the rack 603 to the top, allowing them to be roasted by the hot airflow from all directions.Ensure that all moisture is effectively evaporated. Once the preset baking time is reached, turn off the power and wait for the equipment to stop. Open the protective door of the baking oven 1, pull out the transmission component 5, and the operator can then open the latch 605 again, flip the top cover 601, and remove the dried Chinese medicinal herbs from the baking rack 603.
