Description
Technical Field
[0001] This utility model relates to the field of dandelion seedling processing technology, specifically a blanching device for dandelion seedlings. Background Technology
[0002] Dandelion, a perennial herb used both as food and medicine, has high utilization value in its entirety. In the medicinal field, dandelion contains various effective components such as taraxasterol and inulin, possessing effects such as clearing heat and detoxifying, promoting diuresis and resolving lumps, making it an important ingredient in traditional Chinese medicine formulas. In the edible field, fresh dandelion seedlings, due to their tender texture and rich nutrition, are often processed into cold dishes, teas, and health products, enjoying great market popularity. With the booming development of the health industry, the market demand for deep-processed dandelion continues to rise, placing higher demands on the efficiency and quality of its processing. Blanching, as a key step in the processing of fresh dandelion seedlings, achieves the purposes of blanching, destroying enzyme activity, and removing oxalic acid through high-temperature treatment, directly affecting the color, taste, and shelf life of subsequent products. Therefore, it occupies an important position in the dandelion deep-processing industry chain. In existing technologies, the blanching of dandelion seedlings is mostly accomplished using continuous blanching equipment. This type of equipment typically includes a blanching tank filled with hot water, with heating devices at the bottom or side walls to maintain the water temperature; a feeding mechanism is located above or on one side of the tank to feed the dandelion seedlings to be processed into the tank; and a conveyor system (such as a conveyor belt) is also installed inside the tank to move the seedlings through the hot water to complete the blanching process and transport the processed seedlings to the next step. The working process is roughly as follows: first, the water in the blanching tank is heated to a set temperature by the heating device; then, the dandelion seedlings are fed into the blanching tank through the feeding mechanism; after being soaked or sprayed in the hot water for a certain period of time by the conveyor system, the seedlings are transported out of the tank, completing the blanching operation. However, existing blanching equipment still has some problems when processing fresh dandelion seedlings. On the one hand, because fresh dandelion seedlings are light, have many leaves that are easily tangled, they often pile up during the feeding process, causing a large number of seedlings to be squeezed into the blanching area and unable to be evenly contacted with hot water. On the other hand, during the blanching process, the seedlings are easily clustered on the conveyor device due to the impact of water flow or their own gravity, and the leaves block each other to form "shaded areas," resulting in some areas being underheated while others are over-blanched due to prolonged contact with high-temperature hot water. Both of these situations lead to uneven blanching quality of fresh dandelion seedlings, manifested as inconsistent color and large differences in texture, which seriously affects the consistency of subsequent processed products and market acceptance. Therefore, we propose a blanching device for fresh dandelion seedlings. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a blanching device for fresh dandelion seedlings, which includes a combing mechanism for combing and a silicone strip for pressing and separating, and can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a blanching device for fresh dandelion seedlings, comprising a frame, the front end of which is a blanching tank, a water injection tank in the middle of the left side wall of the frame, the water injection tank being connected to the blanching tank, a heating component inside the blanching tank, and a combing mechanism. The combing mechanism includes a pressure plate, silicone strips, a feed hopper, rotating rollers, and comb teeth. The pressure plate is located inside the frame, and the lower side of the middle part of the pressure plate is provided with evenly distributed silicone strips, all of which are located inside the blanching tank. The feed hopper is fixedly connected to the front end of the upper side of the frame, and the outlet of the feed hopper is located on the upper side of the blanching tank. The rotating rollers are rotatably connected between the left and right side walls of the feed hopper, and the outer arc surface of the rotating rollers is provided with evenly distributed comb teeth. The comb teeth of the rotating rollers in the combing mechanism separate and comb the dandelion seedlings that are piled up during feeding, and the silicone strips under the pressure plate gently push and separate the seedlings that are locally gathered during blanching. This solves the problem of uneven blanching caused by the stacking and gathering of seedlings in the prior art, and improves the uniformity and reliability of blanching.
[0005] Furthermore, a microcontroller is provided on the right side of the frame, and the input terminal of the microcontroller is electrically connected to an external power supply for stable control.
[0006] Furthermore, the combing mechanism also includes guide columns, mounting frames, and guide cylinders. The mounting frames are fixedly connected to the middle of the upper side of the frame, and the middle of the mounting frames is provided with evenly distributed guide cylinders. The guide columns are evenly arranged on the upper side of the middle of the pressure plate, and the guide columns are slidably connected to the guide cylinders adjacent to them on the upper side. Through the sliding cooperation between the guide columns and the guide cylinders, the height of the pressure plate can be adjusted to accommodate seedlings of different heights, while ensuring that the pressure plate moves smoothly and avoiding uneven pressing caused by deviation.
[0007] Furthermore, a rotating shaft is fixedly connected to the center of the right end face of each rotating roller, and a gear is fixedly connected to the middle of each rotating shaft. The two gears mesh together. A motor is installed on the left side of the feed hopper. The output shaft of the motor is fixedly connected to the center of the left side of the rear rotating roller. The input end of the motor is electrically connected to the output end of the microcontroller for stable driving.
[0008] Furthermore, the heating component is an electric heating tube, which is disposed on the bottom wall of the blanching tank. The input end of the electric heating tube is electrically connected to the output end of the microcontroller for heating water.
[0009] Furthermore, the left side wall of the frame is provided with uniformly distributed temperature sensors. The temperature probes of the temperature sensors all penetrate the left side wall of the frame and extend into the interior of the scalding tank. The temperature sensors are all bidirectionally electrically connected to the microcontroller to detect the temperature in real time.
[0010] Furthermore, the frame is equipped with a mesh belt conveyor, the rear end of which is inclined upwards. The mesh belt conveyor has evenly distributed pusher plates on its surface. The front end of the mesh belt conveyor is located below the pressure plate. The input end of the mesh belt conveyor is electrically connected to the output end of a microcontroller for conveying fresh dandelion seedlings.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This dandelion seedling blanching device has the following advantages: The combing mechanism uses evenly distributed comb teeth on the outer arc surface of the rotating roller inside the feed hopper. Driven by a motor, it achieves synchronous rotation in opposite directions through gear meshing. This separates and combs stacked dandelion seedlings into a single layer, effectively avoiding uneven blanching caused by accumulation during feeding. At the same time, the silicone strips evenly distributed on the lower side of the pressure plate can gently push away seedlings that may be locally clustered due to water flow impact or their own stacking in the blanching tank without damaging the seedlings during the conveyor belt transport process. This achieves separation of overlapping seedlings and prevents the formation of "shaded areas" caused by overlapping leaves, which would lead to insufficient blanching in some areas. This improves the uniformity and reliability of blanching. Attached Figure Description

[0015] Please see Figure 1-5 This embodiment provides a technical solution: a blanching device for fresh dandelion seedlings, including a frame 1, a microcontroller 11 on the right side of the frame 1, the input end of the microcontroller 11 being electrically connected to an external power source, a blanching tank 3 inside the front end of the frame 1, a water injection tank 4 in the middle of the left side wall of the frame 1, the water injection tank 4 being connected to the blanching tank 3, a heating component inside the blanching tank 3, the heating component being an electric heating tube 5, the electric heating tube 5 being disposed on the bottom wall of the blanching tank 3, the input end of the electric heating tube 5 being electrically connected to the output end of the microcontroller 11, temperature sensors 6 evenly distributed on the left side wall of the frame 1, the temperature probes of the temperature sensors 6 all penetrating the left side wall of the frame 1 and extending into the interior of the blanching tank 3, the temperature sensors 6 all being bidirectionally electrically connected to the microcontroller 11, and also including a combing mechanism 2. The combing mechanism 2 includes a pressure plate 21, silicone strips 22, a feed hopper 26, a rotating roller 27, and comb teeth 28. The pressure plate 21 is located inside the frame 1, and a mesh belt conveyor 7 is installed inside the frame 1. The rear end of the mesh belt conveyor 7 is inclined upward, and the surface of the mesh belt conveyor 7 is provided with evenly distributed push plates. The front end of the mesh belt conveyor 7 is located below the pressure plate 21. The input end of the mesh belt conveyor 7 is electrically connected to the output end of the microcontroller 11. The combing mechanism 2 also includes guide posts 23, a mounting frame 24, and guide cylinders 25. The mounting frame 24 is fixedly connected to the middle of the upper side of the frame 1. Evenly distributed guide cylinders 25 are provided in the middle of the mounting frame 24. The guide posts 23 are evenly arranged on the upper side of the middle of the pressure plate 21, and each guide post 23 is adjacent to a guide cylinder on the upper side. 25. Sliding connection (the upper side of the middle part of the pressure plate 21 is provided with evenly distributed hooks, and the front side of the outer arc wall of the guide cylinder 25 is threaded with tightening screws, the rear end of the tightening screws is in contact with the outer arc surface of the adjacent guide column 23 on the rear side), the lower side of the middle part of the pressure plate 21 is provided with evenly distributed silicone strips 22 (the silicone strips 22 are traditional silicone strips, which can be used for a long time in the temperature range of -60°C to +250°C and maintain stable physical properties and elasticity), the silicone strips 22 are all located inside the blanching tank 3, the feed hopper 26 is fixedly connected to the front end of the upper side of the frame 1, the discharge port of the feed hopper 26 is located on the upper side of the blanching tank 3, the rotating rollers 27 are rotatably connected between the left and right side walls of the feed hopper 26, and the outer arc surface of the rotating rollers 27 is provided with evenly distributed hooks. The rotating roller 27 has distributed comb teeth 28 (all comb teeth 28 are silicone comb teeth). A rotating shaft 8 is fixedly connected to the center of the right end face of each rotating roller 27. A gear 9 is fixedly connected to the middle of each rotating shaft 8. The two gears 9 mesh together. A motor 10 is installed on the left side of the feed hopper 26. The output shaft of the motor 10 is fixedly connected to the center of the left side of the rear rotating roller 27. The input end of the motor 10 is electrically connected to the output end of the microcontroller 11. When the operator pours dandelion seedlings into the feed hopper 26, the microcontroller 11 controls the motor 10 to start. The motor drives the rear rotating roller 27 to rotate, and through the two meshing gears 9, drives the front rotating roller 27 to rotate synchronously in opposite directions. The comb teeth 28 on the outer arc surface of the rotating roller 27 interlock, separating and combing the stacked seedlings into a single layer, preventing accumulation during feeding. Uneven blanching can occur. After sorting, the fresh seedlings fall through the outlet of the feed hopper 26 onto the mesh conveyor belt 7 inside the blanching tank 3. The blanching tank 3 is pre-filled with an appropriate amount of clean water through the water injection tank 4. The microcontroller controls the electric heating tube 5 to start, heating the water in the tank. The temperature sensor 6 monitors the water temperature in real time and feeds the data back to the microcontroller 11. When the water temperature reaches the set value, such as 90-95℃, the microcontroller 11 adjusts the heating power to maintain a constant temperature. The silicone strip 22 on the lower side of the pressure plate 21 is located inside the blanching tank 3, and the front end of the mesh conveyor belt 7 is located below the pressure plate 21. When the mesh conveyor belt 7 runs, the dandelion seedlings on its surface will move forward. Since the position of the pressure plate 21 is relatively fixed, the silicone strip 22 can be fixed after adjusting its height through the guide column 23 and the guide cylinder 25.Tightening screws secure the pressure plate, ensuring stable pressing force and creating relative movement between it and the moving conveyor belt and seedlings. As the conveyor belt 7 continuously transports the seedlings, they may partially clump together after entering the blanching tank 3 due to water flow impact or their own stacking. At this time, the silicone strip 22 comes into contact with the moving seedlings. Its soft material properties can gently push and pull the stacked seedlings without damaging them, separating the overlapping seedlings. The blanched seedlings leave the water surface with the inclined section at the rear of the conveyor belt 7 and enter the next process. Through the combing mechanism 2 and the pressing and separating by the silicone strip 22, the seedlings are prevented from overlapping leaves forming "shadow areas," which could lead to insufficient blanching in some areas.
[0016] The working principle of the dandelion seedling blanching device provided by this utility model is as follows: The operator pours the dandelion seedlings into the feeding hopper 26. The microcontroller 11 controls the motor 10 to start, and the motor drives the rear rotating roller 27 to rotate. Through two meshing gears 9, the front rotating roller 27 is driven to rotate in opposite directions synchronously. The comb teeth 28 on the outer arc surface of the rotating roller 27 are interlaced to separate and comb the stacked seedlings into a single layer, avoiding uneven blanching caused by accumulation during feeding. The combed seedlings fall into the mesh conveyor belt 7 in the blanching tank 3 through the discharge port of the feeding hopper 26. The blanching tank 3 is pre-filled with an appropriate amount of clean water through the water injection tank 4. The microcontroller controls the electric heating tube 5 to start, heating the water in the tank. The temperature sensor 6 monitors the water temperature in real time and feeds the data back to the microcontroller 11. When the water temperature reaches the set value, such as 90-95℃, the microcontroller 11 adjusts the heating power to maintain a constant temperature. The silicone strip 22 is located inside the blanching tank 3, and the front end of the mesh conveyor belt 7 is located below the pressure plate 21. When the mesh conveyor belt 7 is running, the dandelion seedlings carried on its surface will move forward. Since the position of the pressure plate 21 is relatively fixed, the silicone strip 22 can be fixed after adjusting its height through the guide column 23 and the guide cylinder 25. The tightening screw can fix the position of the pressure plate to ensure stable pressing force and form relative movement with the moving mesh belt and seedlings. As the mesh conveyor belt 7 continues to transport seedlings, the seedlings may locally gather due to water flow impact or their own stacking after entering the water area of the blanching tank 3. At this time, the silicone strip 22 will come into contact with the moving seedlings. Its soft material properties can generate a gentle pushing and pushing force on the stacked seedlings without damaging them, separating the stacked seedlings. The blanched seedlings leave the water surface with the inclined section at the rear end of the mesh conveyor belt 7 and enter the next process.
