Description

Technical Field

[0001] This invention relates to the field of tea aging equipment technology, specifically to a Huangda tea stacking and aging device based on the effect of moisture and heat coupling. Background Technology

[0002] Huangda tea belongs to the post-fermented tea category. The key to its quality lies in the control of temperature and humidity during the aging process. Traditional processing includes steps such as fixation, rolling, initial drying, and pile aging (yellowing). Among these, pile aging is the key process that distinguishes Huangda tea from green tea. This process involves controlling the tea leaves under certain temperature and humidity conditions to promote the non-enzymatic auto-oxidation and transformation of substances such as tea polyphenols, causing the tea leaves to change from green to yellow, with a mellow taste and pure aroma.

[0003] The fermentation (yellowing) process of Huangda tea requires multiple turning processes. Static yellowing equipment only has temperature and humidity control functions and no turning mechanism, so manual intervention is still required. Although drum-type yellowing equipment can turn the tea leaves, the tea leaves tumble violently inside the drum, which can easily cause the tea leaves to break.

[0004] In summary, existing tea stacking and aging equipment lacks a flexible turning structure and is not suitable for processing strip-shaped teas such as Huangda tea. Summary of the Invention

[0005] The purpose of this invention is to provide a Huangda tea stacking and aging device based on the effect of moisture and heat coupling, so as to solve the problem of easy breakage of Huangda tea strips during the turning process of Huangda tea in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: A device for the accumulation and aging of Huangda tea based on the effect of moisture and heat coupling, comprising: The box body has a feed inlet on its top plate and a discharge outlet on its side wall; An alcoholic beverage tank is located inside the housing and divides the housing into an air inlet chamber and an auxiliary chamber. The bottom plate of the alcoholic beverage tank has a perforated plate structure and a condensate recovery tank is provided at its bottom. A hinge is fixedly connected to the middle of the bottom plate of the alcoholic beverage tank. A rotating shaft parallel to the width direction of the alcoholic beverage tank is fixedly connected to the hinge. The rotating shaft passes through the side wall of the housing and is connected to a rotary drive component so that the alcoholic beverage tank can rotate around the rotating shaft to adjust the tilt angle. A turning roller is arranged parallel to the rotating shaft. The side wall of the turning roller is provided with multiple flexible turning plates. The two shaft ends of the turning roller are connected to the alcoholization tank through symmetrically arranged linear actuators. A humidity and heat coupling control device is used to create a constant temperature and humidity environment inside the alcoholization tank; One end of the linear actuator is fixedly connected to the end of the alcoholization tank near the feed inlet, and the other end is rotatably connected to the shaft of the turning roller to drive the turning roller to reciprocate along the length of the alcoholization tank.

[0007] Furthermore, the linear actuator includes a support plate spanning one end of the ethanolation tank near the feed inlet and a telescopic push rod connecting the support plate and the turning roller. Two racks are symmetrically fixed on both sides of the ethanolation tank, and gears are fixedly connected to the shaft ends on both sides of the turning roller. The gears mesh with the racks, so that the turning roller reciprocates along the racks while rotating.

[0008] Furthermore, multiple flexible turning plates are provided, arranged axially at equal intervals along the spiral line of the side wall of the turning roller, and the radial angle of every two adjacent flexible turning plates differs by 30°.

[0009] Furthermore, the height of the flexible turning plate is greater than the distance between the lowest point of the turning roller and the middle of the bottom of the alcoholization tank.

[0010] Furthermore, the cross-section of the alcoholic beverage tank is U-shaped, and a flexible corrugated plate is fixedly connected between the end of the alcoholic beverage tank near the support plate and the inner wall of the box to seal the gap between the alcoholic beverage tank and the inner wall of the box.

[0011] Furthermore, there is an inclined baffle between the end of the aging tank away from the feed inlet and the inner wall of the box. When the aging tank is in a horizontal position, the bottom of the aging tank is level with and in close contact with the lowest point of the baffle. When the aging tank is flipped, the aging tank separates from the baffle to form a channel through which tea leaves can pass.

[0012] Furthermore, the moisture-heat coupling control device includes: The heating device includes air ducts symmetrically arranged on both sides of the inner wall of the air inlet chamber. The air ducts are parallel to the length direction of the alcohol tank. The starting point of the air duct is a first air inlet located on the side wall of the box. The first air inlet is connected to a hot air blower to input dry hot air into the air duct. The side wall of the air duct is provided with a plurality of second air inlets at equal intervals along its length direction. The ending point of the air duct is a vent located on the top plate of the box. An exhaust fan is provided at the vent. A humidification device is installed inside the condensate recovery tank to supplement atomized water vapor into the air inlet cavity; Temperature and humidity detection devices are distributed inside the alcoholization tank and the box body to detect the temperature and humidity parameters of the material along the process. The control device is electrically connected to the heating device, the humidification device, the temperature and humidity detection device, the linear actuator, and the rotary drive, respectively.

[0013] Furthermore, a cold water tank is provided on the outside of the box. At the lowest point of the cold water tank, multiple water pipes are connected by a water pump. The water pipes pass through the box and enter the interior of the condensate recovery tank. Multiple atomizing nozzles pointing towards the bottom plate of the alcohol-processing tank are equidistantly arranged along the length of the water pipes.

[0014] Furthermore, the bottom of the condensate recovery tank is inclined, with its lowest point close to one end of the cold water tank, and a water collection box is provided at the bottom of the condensate recovery tank. A drain valve is provided between the water collection box and the condensate recovery tank, and the inner wall of the condensate recovery tank is coated with a superhydrophobic coating.

[0015] Furthermore, a heating plate is inclinedly arranged at the bottom of the auxiliary cavity, and the lowest point of the heating plate is in contact with the discharge port. Multiple air outlets are equidistantly opened on both sides of the auxiliary cavity along its length.

[0016] Compared with the prior art, the present invention has the following advantages: In this invention, the combination of gear-rack and telescopic push rod enables the turning device to rotate while reciprocating linear motion, ensuring uniform turning and intact blades; At the same time, by rotating the shaft to drive the fermentation tank to flip, the tea leaves in the corners are moved in the fermentation tank under the action of gravity, further ensuring that the turning is thorough.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the Huangda tea stacking and aging device based on the effect of moisture and heat coupling provided in this application includes: The housing 1 has an inlet 2 and an outlet 3. The inlet 2 is located near the top plate, and the outlet 3 is located on the side wall near the other end, so as to form a smooth material flow path.

[0021] The aging tank 4 is located inside the housing 1, dividing the interior of the housing 1 into an air inlet chamber 5 and an auxiliary chamber 6. The bottom plate of the aging tank 4 has a perforated plate structure, and a condensate recovery tank 7 is provided at its bottom. The aging tank 4 is used to hold the yellow tea material to be aged. The perforated plate structure allows hot and humid gas to penetrate the material layer, while allowing condensate to seep downwards. The condensate recovery tank 7 is located directly below the perforated plate structure and is used to collect the condensate that seeps down from the material layer to prevent moisture from accumulating at the bottom of the material.

[0022] A hinge seat 8 is fixedly connected to the middle of the bottom plate of the aging tank 4. A rotating shaft 9 parallel to the width direction of the aging tank 4 is fixedly connected to the hinge seat 8. The rotating shaft 9 passes through the side wall of the box 1 and is connected to a rotary drive component 10 so that the aging tank 4 can rotate around the rotating shaft 9 to adjust the tilt angle. During the aging process, the aging tank 4 remains horizontal or nearly horizontal. When discharging, the aging tank 4 tilts towards the discharge port 3 so that the tea leaves automatically slide towards the discharge port 3 under the action of gravity, achieving convenient discharge.

[0023] The turning roller 11 is arranged parallel to the rotating shaft 9. Multiple flexible turning plates 12 are provided on the side wall of the turning roller 11. The two shaft heads of the turning roller 11 are connected to the aging tank 4 through symmetrically arranged linear actuators 13. As the turning roller 11 rotates and moves, the flexible turning plates 12 turn and loosen the piled tea leaves, so that the internal materials can fully contact the external hot and humid gas, while avoiding rigid contact that could damage the tea leaves.

[0024] The moisture-heat coupling control device includes: The heating device includes air ducts 14 symmetrically arranged on the inner walls of both sides of the air inlet chamber 5. The air ducts 14 are parallel to the length direction of the alcohol-processing tank 4. The starting point of the air ducts 14 is a first air inlet 15 located on the side wall of the housing 1. The first air inlet 15 is connected to a hot air blower 16 to input dry hot air into the air ducts 14. The side wall of the air ducts 14 is provided with a plurality of second air inlets 17 at equal intervals along its length direction. The ending point of the air ducts 14 is a humidification outlet 18 located on the top plate of the housing 1. An exhaust fan 28 is provided at the humidification outlet 18.

[0025] The dry hot air generated by the hot air blower 16 enters the air duct 14 through the first air inlet 15. As it flows along the air duct 14, it diffuses evenly into the air inlet cavity 5 through multiple second air inlets 17. Finally, the hot and humid air is discharged from the exhaust port 18 through the exhaust fan 28, forming a continuous airflow circulation.

[0026] The humidification device is installed inside the condensate recovery tank 7 and is used to supplement the air inlet chamber 5 with atomized water vapor, which mixes with the hot air input by the hot air blower 16 to form humid and hot gas.

[0027] Temperature and humidity detection devices are distributed inside the alcoholization tank 4 and the box 1 to detect the temperature and humidity parameters of the material along the process. The control device is electrically connected to the heating device, the humidification device, the temperature and humidity detection device, the linear actuator 13, and the rotary drive 10, respectively. One end of the linear drive 13 is fixedly connected to the end of the alcohol tank 4 near the feed inlet 2, and the other end is rotatably connected to the shaft of the turning roller 11 to drive the turning roller 11 to reciprocate along the length of the alcohol tank 4.

[0028] In this embodiment, as Figure 5 and Figure 6 As shown, the linear actuator 13 includes a support plate 131 spanning one end of the alcohol tank 4 near the inlet 2 and a telescopic push rod 132 connecting the support plate 131 and the turning roller 11. Two racks 133 are symmetrically fixed on both sides of the alcohol tank 4. Gears 134 are fixedly connected to the shaft ends on both sides of the turning roller 11. The gears 134 mesh with the racks 133 so that the turning roller 11 moves back and forth along the racks 133 while rotating.

[0029] The linear drive 13 is preferably a railcar, which straddles two tracks set on both sides of the alcoholization tank 4 and travels in a straight line along the tracks. A motor is fixedly installed on the railcar, and the motor is connected to the gear 134 for transmission. That is, the gear 134 drives the railcar to move in a straight line, while driving the turning roller 11 to roll.

[0030] On the other hand, the linear actuator 13 can also adopt a telescopic push rod 132. Specifically, when the linear actuator 13 adopts a telescopic push rod 132, the telescopic push rod 132 can be an electric push rod, a pneumatic push rod, or a ball screw. It is preferred to adopt an electric push rod. The cylinder end of the telescopic push rod 132 is fixedly connected to both ends of the support plate 131 through a hinge or flange. Its piston rod end is fixedly connected to the shaft bearing seat or roller end plate of the turning roller 11 through a flange. The installation direction of the telescopic push rod 132 is parallel to the length direction of the alcohol trough 4 to ensure that the thrust direction is consistent with the movement direction of the turning roller 11.

[0031] In this embodiment, multiple flexible turning plates 12 are provided, arranged axially at equal intervals along the spiral line of the side wall of the turning roller 11, and the radial angle of every two adjacent flexible turning plates 12 differs by 30°.

[0032] Specifically, each flexible turning plate 12 is a long strip or rake-shaped structure, made of food-grade silicone, rubber and other flexible materials, and has a certain degree of elasticity. One end is a fixed end and the other end is a free end. The fixed end is fixed to the surface of the turning roller 11 by snap-fit ​​connection or vulcanization bonding, and the free end extends radially outward toward the turning roller 11. When the turning roller 11 rotates, it can penetrate into the tea material layer to a certain depth. The free end is provided with rounded corners to reduce mechanical damage to the tea strips.

[0033] Specifically, with the axis of the turning roller 11 as the center, the included angles of two adjacent flexible turning plates 12 in the circumferential direction differ by 30°. Each flexible turning plate 12 is distributed in a spiral step shape in three-dimensional space. The trajectories of multiple flexible turning plates 12 are connected to each other in the axial direction and overlap appropriately, thereby forming a continuous turning and covering in the width direction of the entire alcoholization tank 4 (i.e., the axial direction of the turning roller 11). There is no axial blind area that is not turned. At the same time, the cutting angle of each turning is different, thereby producing a multi-directional loosening and mixing effect on the material layer, avoiding the problem of uneven destruction of the material layer structure or local compaction caused by turning in one direction.

[0034] In this embodiment, the height of the flexible turning plate 12 is greater than the distance between the lowest point of the turning roller 11 and the middle of the bottom of the alcoholization tank 4.

[0035] In this embodiment, as Figure 7 As shown, the cross-section of the alcohol aging tank 4 is U-shaped. A flexible corrugated plate 19 is fixedly connected between the end of the alcohol aging tank 4 near the support plate 131 and the inner wall of the box body 1 to seal the gap between the alcohol aging tank 4 and the inner wall of the box body 1.

[0036] Specifically, the flexible corrugated plate 19 is made of elastic material. When the alcoholic beverage tank 4 is horizontal, the flexible corrugated plate 19 is in a compressed state. When the alcoholic beverage tank 4 is rotated at a certain angle, the flexible corrugated plate 19 unfolds, always sealing the gap between the alcoholic beverage tank 4 and the inner wall of the box 1.

[0037] In this embodiment, there is an inclined baffle 20 between the end of the aging tank 4 away from the feed inlet 2 and the inner wall of the box 1. When the aging tank 4 is in a horizontal position, the bottom of the aging tank 4 is level with the lowest point of the baffle 20 and in close contact. When the aging tank 4 is flipped, the aging tank 4 separates from the baffle 20 to form a channel through which tea leaves can pass.

[0038] Specifically, when the aging tank 4 is in a horizontal position, the bottom of the aging tank 4 and the lowest point of the baffle 20 form a complete U-shaped container to carry the tea for aging. When the aging tank 4 is flipped, the aging tank 4 separates from the baffle 20, and the tea can slide along the inclined aging tank 4 into the auxiliary cavity 6 to achieve automatic discharge.

[0039] In this embodiment, as Figure 8 As shown, a cold water tank 21 is provided on the outside of the box 1. Multiple water pipes 22 are connected to the lowest point of the cold water tank 21 via a water pump. The water pipes 22 penetrate the box 1 and enter the interior of the condensate recovery tank 7. Multiple atomizing nozzles 23 pointing to the bottom plate of the alcohol-processing tank 4 are equidistantly arranged along the length of the water pipes 22.

[0040] Specifically, the walls of the cold water tank 21 are equipped with semiconductor cooling chips, which ensure that the water temperature inside the cold water tank 21 is always lower than the room temperature. When the tank 1 needs to be cooled, the flow rate of atomized water vapor is increased. The water inlet of the water pump is connected to the water outlet at the lowest point of the cold water tank 21 through a hose. The water outlet of the water pump is connected to multiple water pipes 22 through a water distributor or by direct diversion. Multiple water pipes 22 are provided and are symmetrically arranged along the width of the condensate recovery tank 7. The atomizing nozzle 23 is preferably an ultrasonic atomizer or a high-pressure micro-mist nozzle.

[0041] In this embodiment, the bottom of the condensate recovery tank 7 is inclined, with its lowest point close to one end of the cold water tank 21. A water collection box 24 is provided at the bottom of the condensate recovery tank 7, and a drain valve 25 is provided between the water collection box 24 and the condensate recovery tank 7. The inner wall of the condensate recovery tank 7 is coated with a superhydrophobic coating.

[0042] Specifically, the drain valve 25 is preferably a responsive hydrogel microvalve. The condensate inside the condensate recovery tank 7 is collected in a directional manner under the action of gravity. The responsive characteristics of hydrogel to environmental stimuli (such as temperature and humidity) are used to realize the automatic sensing of the condensate level and the adaptive opening of the valve, so as to guide the condensate collected inside the condensate recovery tank 7 to the water collection box 24.

[0043] In this embodiment, as Figure 9 As shown, a heating plate 26 is inclinedly arranged at the bottom of the auxiliary cavity 6. The lowest point of the heating plate 26 is in contact with the discharge port 3. Multiple air outlets 27 are equidistantly opened on both sides of the auxiliary cavity 6 along its length direction.

[0044] The specific working method includes the following steps: Step 1: After the tea leaves have been withered, rolled, and dried, and have a moisture content of 25% to 28%, spread them evenly into the aging trough 4 through the feed inlet 2, to a thickness of 25cm. Step 2: Temperature and humidity sensors installed in the housing 1 and the alcoholization tank 4 detect the temperature and humidity inside the air inlet cavity 5. The controller receives the temperature and humidity signals and sends open / close signals to the hot air blower 16 and the atomizing nozzle 23. The hot air blower 16 blows hot air into the air inlet cavity 5 through the air duct 14 and the second air inlet 17. The atomizing nozzle 23 sprays water mist into the air inlet cavity 5. By adjusting the power of the hot air blower 17 to heat the water mist sprayed by the atomizing nozzle 23, the temperature inside the air inlet cavity 5 is maintained at 30°C and the humidity is maintained at 65%. The telescopic push rod 132 is activated to drive the turning roller 11 to move back and forth along the rack 133. The flexible turning plate 12 completes a complete turning within 2 minutes. The total duration of the wet heat treatment is 6 hours, and the turning is carried out 4 times in total. Step 3: Start the rotary drive 10 to drive the rotating shaft 9 to rotate, causing the aging tank 4 to rotate 30°. The tea leaves slide into the auxiliary chamber 6. Start the heating plate 26 to re-dry the tea leaves inside the auxiliary chamber 6, evaporating the moisture inside the tea leaves and expelling it from the air outlet 27. The moisture content of the re-dried tea leaves is 20%~22%. Step 4: The re-dried tea leaves are spread into the aging tank 4 again through the feed inlet 2, with a thickness of 20cm. The temperature and humidity sensors installed in the box 1 and the aging tank 4 detect the temperature and humidity inside the air inlet 5 again. The controller receives the temperature and humidity signals and sends the start and stop signals to the hot air blower 16 and the atomizing nozzle 23. The hot air blower 16 and the atomizing nozzle 23 are started to keep the temperature inside the air inlet 5 at 35℃ and the humidity at 55%. The telescopic push rod 132 is activated to drive the turning roller 12 to move back and forth along the rack 133. The flexible turning plate 12 completes a complete turning within 2 minutes. The total duration of the wet heat treatment is 6 hours, and the tea leaves are turned 4 times in total. Step 5: Start the rotary drive 10 to drive the rotating shaft 9 to rotate the aging tank 4 by 30°, the tea leaves slide into the auxiliary chamber 6 and are taken out from the discharge port 3, and dry at 140℃~150℃ until the moisture content is 7%~8%; Step 6: Refill the fully dried leaves into the alcoholization tank 4 through feed inlet 2, with a thickness of 35cm; The temperature and humidity sensor detects the temperature and humidity inside the air inlet cavity 5. The controller receives the temperature and humidity signals and sends an on / off signal to the hot air blower 16 and the atomizing nozzle 23 to turn on the hot air blower 16 and the atomizing nozzle 23. The controller receives the temperature and humidity signals sent by the temperature and humidity sensor in real time to adjust the power of the hot air blower 16 and the flow rate of the atomizing nozzle 23 to control the temperature and humidity of the air inlet cavity 5. Days 1-15: Temperature 10℃, Humidity 50%; Days 16-30: Temperature 15℃, Humidity 45%; Days 31-60: Temperature 20℃, Humidity 40%; The telescopic push rod 132 is activated every 5 days to drive the turning roller 11 to reciprocate and rotate at 0.1 m / s, each time for 10 minutes; Step 7: After aging is complete, start the rotary drive 10 to drive the aging tank 4 to rotate 30° so that the tea leaves enter the auxiliary chamber 6 and open the discharge port 3 to take out the tea leaves.
