The fixing tank is fixedly connected to the base, and a feeding seat is fixedly connected to the outer surface of the fixing tank.

[0010] Preferably, the outer surface of the base is provided with a controller, which is electrically connected to the servo motor, electric telescopic rod, heating pipe, fan, cooler, electric lead screw frame and drive unit.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This high-efficiency tea fixing and cooling device uses an electric telescopic rod to drive the plug to regulate the opening and closing of the feeding seat. Heating is supplied through heating pipes in the heating chamber, and a servo motor drives the rollers and spiral frying conveyor to rotate. This ensures the tea is continuously fryed and evenly heated during transport. Simultaneously, a fan blows hot air through a spray pipe onto the tea for even heating. Waste gas from fixing is filtered through a recovery pipe and purifier before being recycled back to the spray pipe. The spiral frying conveyor simultaneously completes the frying and transporting, allowing the tea to be continuously processed from feeding to fixing and cooling. This reduces uneven contact area between the tea and the heat source, preventing moisture content deviations within the same batch of tea and directly affecting subsequent rolling and drying.

[0012] 2. This high-efficiency tea fixing and cooling device uses an electric screw frame at the fixing tank end to drive the cover plate to slide, forming a sliding control structure with the cooling box. This allows for precise control of the timing and rate at which tea leaves enter the cooling box from the fixing tank. Simultaneously, the drive unit inside the external drive housing rotates the ventilation plate, agitating the airflow inside the box and assisting in turning the tea leaves, breaking up airflow stagnation and ensuring that the tea leaves are evenly exposed to cold air. This improves cooling efficiency and prevents flavor loss. Furthermore, the discharge hopper at the bottom of the cooling box uses a pluggable baffle to control the discharge speed, flexibly adjusting the discharge speed and preventing accumulation and blockage. When not discharging, it can also temporarily store tea leaves, reducing transportation losses and contamination. In addition, the cooler at the top of the cooling box generates low-temperature cold air based on the refrigeration principle and continuously delivers it into the box, rapidly lowering the temperature inside and effectively locking in the fresh and crisp substances of the tea leaves, preventing color darkening and bitterness. This ensures that the cooling degree of the same batch of tea is consistent, improving quality stability. Attached Figure Description

[0015] 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.

[0016] Example 1: Please refer to Figures 1-3. A high-efficiency tea fixing and cooling device includes a fixing tank 1 and a base 21. The fixing tank 1 is fixedly connected to the base 21. A feeding seat 2 is fixedly connected to the outer surface of the fixing tank 1. An electric telescopic rod 3 is fixedly installed through the outer surface of the feeding seat 2. A plug 4 is fixedly installed at the output end of the electric telescopic rod 3. A fan 11 and a cooling box 15 are fixedly installed on the outer surface of the base 21. A spray pipe 12 is rotatably connected to the output end of the fan 11. A servo motor 8 is provided on the outer surface of the fixing tank 1. A roller 9 is fixedly installed at the output end of the servo motor 8. A spiral stirring conveyor 10 is fixedly installed on the outer surface of the roller 9. A recovery pipe 13 is fixedly connected to the outer surface of the fixing tank 1. A purifier 14 is connected to the output end of the recovery pipe 13. A circulation pipe 22 is connected to the output end of the purifier 14. The output end of the circulation pipe 22 is connected to the spray pipe 12. A heating chamber 5 is opened in the inner wall of the fixing tank 1. A heating pipe is provided inside the heating chamber 5.

[0017] Specifically, the opening and closing of the feed seat 2 is controlled by the electric telescopic rod 3 driving the blocking part 4, and then the heating pipe in the heating chamber 5 provides heat. In conjunction with the servo motor 8, the roller 9 and the spiral frying conveyor 10 rotate, so that the tea leaves are continuously frying and evenly heated during the conveying process. At the same time, the fan 11 blows hot air onto the tea leaves through the spray pipe 12 for even heating. Meanwhile, the waste gas from the fixation process is filtered through the recovery pipe 13 and the purifier 14 and then returned to the spray pipe 12 through the circulation pipe 22 for recycling. Moreover, the spiral frying conveyor 10 completes the frying and conveying simultaneously, so that the tea leaves can be continuously processed from feeding to fixation and cooling. This reduces the uneven contact area between the tea leaves and the heat source, which can cause the moisture content of the same batch of tea leaves to deviate, directly affecting the effect of subsequent rolling and drying.

[0018] In this embodiment: the inner wall of the feed seat 2 is provided with a sealing groove that matches the plug 4, the outer surface of the plug 4 is provided with a sealing gasket layer, the part of the spray pipe 12 located inside the blanching tank 1 is fixedly installed with multiple evenly distributed atomizing nozzles, the spray pipe 12 is made of heat-resistant metal, the outer surface of the spiral stir-frying conveyor 10 is fixedly installed with multiple evenly distributed stir-frying protrusions, the spray pipe 12 is located inside the roller 9, the purifier 14 is fixedly installed with a filter layer and an activated carbon adsorption layer, and a one-way valve is fixedly installed on the circulation pipe 22.

[0019] Specifically, the inner wall sealing groove of the feed seat 2 and the sealing gasket of the plug 4 form a double seal, maintaining a tight fit when the plug 4 is opened and closed by the electric telescopic rod 3. This prevents tea leakage and loss, as well as contamination from external impurities, ensuring processing cleanliness and raw material utilization. The spray pipe 12 is made of heat-resistant metal to withstand high temperatures. It is paired with a uniform atomizing nozzle to convert the airflow into a uniform atomization state. The built-in roller 9 rotates synchronously with it to achieve close-range air distribution, which not only avoids local temperature differences in the tea and extends the equipment's lifespan, but also shortens the airflow conduction distance and enhances the uniformity and efficiency of blanching or cooling. The spiral frying conveyor 10 has a uniform frying convex... The block increases the amplitude and frequency of tea leaf turning through mechanical action, breaking up the stacked layers to ensure that each tea leaf is heated or aired evenly, reducing batch quality differences; the filter layer inside the purifier 14 intercepts solid impurities, and the activated carbon adsorption layer adsorbs odors and harmful substances. Through dual purification, the cleanliness of the circulating gas is improved, harmful emissions are reduced, and environmental protection requirements are met; the one-way valve on the circulation pipe 22 only allows purified gas to flow from the purifier 14 to the injection pipe 12, blocking backflow of airflow and preventing secondary pollution of purified gas or unpurified waste gas from entering the circulation, ensuring the stability of the circulation system and the quality of the tea leaves. All structures work together to improve the overall processing performance of the device.

[0020] Working principle: Because the blanching tank 1 is fixedly connected to the base 21, the outer surface of the blanching tank 1 is fixedly connected to the feeding seat 2, and the outer surface of the feeding seat 2 is fixedly installed with an electric telescopic rod 3. A plug 4 is fixedly installed at the output end of the electric telescopic rod 3. The outer surface of the base 21 is fixedly installed with a fan 11 and a cooling box 15. At the same time, the output end of the fan 11 is connected to the spray pipe 12. The outer surface of the blanching tank 1 is equipped with a servo motor 8. The output end of the servo motor 8 is fixedly installed with a roller 9. The outer surface of the roller 9 is fixedly installed with a spiral stirring conveyor 10. In addition, the outer surface of the blanching tank 1 is fixedly connected to a recovery pipe 13. The output end of the recovery pipe 13 is connected to a purifier 14. The output end of the purifier 14 is connected to a circulation pipe 22. The output end of the circulation pipe 22 is connected to the spray pipe 12. Moreover, a heating chamber 5 is opened in the inner wall of the blanching tank 1. Heating pipes are installed inside the heating chamber 5. The electric telescopic rod 3 drives the plug 4 to regulate the opening and closing of the feed seat 2. The heating pipes in the heating chamber 5 provide heat, and the servo motor 8 drives the rollers 9 and the spiral frying conveyor 10 to rotate, so that the tea leaves are continuously frying and evenly heated during the conveying process. At the same time, the fan 11 blows hot air through the spray pipe 12 to the tea leaves for even heating. Meanwhile, the waste gas from the fixation process is filtered through the recovery pipe 13 and the purifier 14 and then returned to the spray pipe 12 through the circulation pipe 22 for recycling. Moreover, the spiral frying conveyor 10 completes the frying and conveying simultaneously, so that the tea leaves can be continuously fryed, fixed, and cooled from feeding. Compared with related technologies, the efficient fixation and cooling device for tea leaves provided by this utility model has the following beneficial effects: it reduces the uneven contact area between the tea leaves and the heat source, which causes the moisture content of the same batch of tea leaves to deviate, thus directly affecting the effect of subsequent rolling and drying.

[0021] Example 2: Please refer to Figures 1-3. An electric lead screw frame 6 is fixedly installed on the outer surface of the blanching tank 1 away from the servo motor 8. A cover plate 7 is slidably connected to the outer surface of the electric lead screw frame 6. The cover plate 7 is slidably connected to the cooling box 15. A drive housing 17 is provided on the outer surface of the cooling box 15. A drive unit is provided inside the drive housing 17. A ventilation plate 18 is fixedly installed at the output end of the drive unit. The ventilation plate 18 is rotatably connected to the cooling box 15. A discharge hopper 19 is fixedly connected to the bottom of the cooling box 15. A baffle 20 is inserted and connected to the outer surface of the discharge hopper 19. A cooler 16 is fixedly installed on the top of the cooling box 15.

[0022] Specifically, the electric screw frame 6 at the end of the fixing tank 1 drives the cover plate 7 to slide, forming a sliding control structure with the cooling box 15. This allows for precise control of the timing and rate at which tea leaves enter the cooling box 15 from the fixing tank 1, preventing insufficient fixing or heat loss. Simultaneously, closing the cooling box blocks impurities, ensuring clean processing. The drive unit inside the external drive housing 17 of the cooling box 15 drives the ventilation plate 18 to rotate. This rotational agitation principle stirs the airflow inside the box and assists in turning the tea leaves, breaking airflow stagnation and ensuring even contact between the tea leaves and the cold air, improving cooling efficiency and preventing flavor loss. The discharge hopper 19 at the bottom of the cooling box 15 uses a pluggable baffle 20 for controlled discharge, allowing for flexible adjustment of the discharge speed to prevent accumulation and blockage. When not discharging, it can also temporarily store tea leaves, reducing transport losses and contamination. The cooler 16 at the top of the cooling box 15 generates low-temperature cold air based on refrigeration principles and continuously delivers it into the box, rapidly lowering the temperature and effectively locking in the freshness of the tea leaves, preventing darkening of color and bitterness. It also ensures consistent cooling levels for the same batch of tea, improving quality stability.

[0023] In this embodiment: the heating pipe is a spiral coil structure and the material of the heating pipe is copper alloy. The inner wall of the heating chamber 5 is provided with a heat insulation layer. The electric lead screw frame 6 includes a drive motor and a lead screw. The lead screw is threadedly connected to the cover plate 7. The outer surface of the cover plate 7 is provided with a sealing strip. The discharge hopper 19 is an inverted trapezoidal structure. The outer surface of the baffle 20 is fixedly installed with a handle that is easy to pull out. A sealing gasket is provided between the baffle 20 and the discharge hopper 19.

[0024] Specifically, the heating pipe adopts a spiral coil structure to increase the contact area with the inner wall of the blanching tank 1 and the range of heat radiation. Combined with a copper alloy material with high thermal conductivity, it can quickly transfer heat. At the same time, the insulation layer on the inner wall of the heating chamber 5 reduces heat loss, achieving uniform heat distribution within the blanching tank 1, avoiding uneven blanching of the tea leaves, improving heating efficiency, shortening heating time, and reducing energy consumption. The electric lead screw frame 6 uses a drive motor to rotate the lead screw. The threaded connection between the lead screw and the cover plate 7 converts the rotational motion into linear sliding of the cover plate 7, which, in conjunction with the sealing strip on the outer surface of the cover plate 7, fills the gaps in the fit. The gap is precisely controlled to control the opening and closing range of the connection between the fixing tank 1 and the cooling box 15, optimizing the timing and speed of tea delivery, while preventing air leakage and dust ingress, avoiding heat loss from the fixing tank 1 and tea contamination; the discharge hopper 19 is designed with an inverted trapezoidal structure, with inclined side walls to guide the tea to slide down naturally, and the handle on the outer surface of the baffle 20 allows for quick manual adjustment of the position, and the sealing gasket between the baffle 20 and the discharge hopper 19 fills the gap to prevent tea from accumulating and clogging in the discharge hopper 19, improving the ease of operation of the baffle 20, reducing the leakage of tea fragments and the entry of external impurities, and ensuring smooth discharge and tea quality.

[0025] In the embodiment: the cooler 16 is an air-cooled cooler 16, and the air outlet of the cooler 16 is set towards the ventilation plate 18 inside the cooling box 15. The top of the base 21 is fixedly installed with multiple support seats for supporting the blanching tank 1, and the bottom of the base 21 is provided with anti-slip and shock-absorbing pads.

[0026] Specifically, the air-cooled cooler 16 uses an internal fan to force in outside air and cool it to generate low-temperature cold air. Its air outlet faces the ventilation plate 18 inside the cooling box 15. When the ventilation plate 18 is rotated by the drive unit, the cold air is directly blown onto the ventilation plate 18 and quickly dispersed and diffused to all areas of the cooling box 15 by its rotation. This avoids uneven cooling of the tea caused by direct cold air blowing and improves heat exchange efficiency and shortens cooling time by strengthening the contact between cold air and tea. This ensures that the same batch of tea is cooled consistently and locks in the fresh flavor and color. The multiple support seats on the top of the base 21 form a multi-point support structure to support and distribute the weight of the fixing tank 1 to avoid local deformation caused by weight concentration. The anti-slip and shock-absorbing pads at the bottom of the base 21 are made of a composite of elastic shock-absorbing material and high-friction anti-slip material. They can absorb the vibration generated by the operation of the equipment through elastic deformation, reduce the impact wear and noise of the parts, and prevent the base 21 from shifting through the high-friction surface. Together, they ensure the overall stable operation of the equipment and the safety of processing.

[0027] In this embodiment: a controller is provided on the outer surface of the base 21, and the controller is electrically connected to the servo motor 8, the electric telescopic rod 3, the heating pipe, the fan 11, the cooler 16, the electric lead screw frame 6 and the drive unit.

[0028] Specifically, the controller on the outer surface of the base 21 serves as the core control unit of the high-efficiency tea processing and cooling device. Through electrical connections with the servo motor 8, electric telescopic rod 3, heating pipes, fan 11, cooler 16, electric lead screw frame 6, and drive unit, it collects real-time operating status data of each component. On the other hand, based on preset tea processing parameters, it sends precise control commands to each component synchronously or stepwise, avoiding process disconnect caused by independent operation of a single component. It not only improves the degree of automation and reduces manual intervention costs and operational errors, but also ensures process accuracy. By adjusting the parameters of each component in real time, it ensures consistent processing conditions for each batch of tea, improves quality stability, optimizes process coordination to avoid tea accumulation or waiting, improves production efficiency, and can provide real-time feedback on abnormal component status, facilitating operators to correct parameters and troubleshoot faults, reducing the impact of equipment failure on production.

[0029] Working Principle: An electric screw frame 6 is fixedly installed on the outer surface of the blanching tank 1 away from the servo motor 8. A cover plate 7 is slidably connected to the outer surface of the electric screw frame 6, and the cover plate 7 is slidably connected to the cooling box 15. A drive housing 17 is set on the outer surface of the cooling box 15, and a drive unit is set inside the drive housing 17. A ventilation plate 18 is fixedly installed at the output end of the drive unit and is rotatably connected to the cooling box 15. A discharge hopper 19 is fixedly connected to the bottom of the cooling box 15, and a baffle 20 is inserted and connected to the outer surface of the discharge hopper 19. A cooler 16 is fixedly installed on the top of the cooling box 15. The electric screw frame 6 at the blanching tank 1 drives the cover plate 7 to slide, forming a sliding control structure with the cooling box 15. This allows for precise control of the timing and rate at which the tea leaves enter the cooling box 15 from the blanching tank 1. At the same time, the drive housing 17 outside the cooling box 15... The drive unit inside 7 rotates the ventilation plate 18, which stirs the airflow inside the box and helps to turn the tea leaves by rotating and stirring. This breaks the airflow stagnation, allowing the tea leaves to come into even contact with the cold air, improving cooling efficiency and preventing flavor loss. In addition, the discharge hopper 19 at the bottom of the cooling box 15 can control the discharge through the plug-in baffle 20, which can flexibly adjust the discharge speed to prevent accumulation and blockage. When there is no need to discharge, the tea leaves can be temporarily stored to reduce transportation losses and pollution. In addition, the cooler 16 at the top of the cooling box 15 generates low-temperature cold air based on the refrigeration principle and continuously delivers it into the box, which quickly lowers the temperature inside the box and effectively locks in the fresh substances of the tea leaves, preventing the color from darkening and the flavor from becoming bitter. Compared with related technologies, the efficient tea fixing and cooling device provided by this utility model has the following beneficial effects: thereby ensuring that the cooling degree of the same batch of tea leaves is consistent and improving the quality stability.
