Description

Technical Field

[0001] The invention relates to the technical field of tea leaf withering, and in particular to an energy-saving and efficient tea leaf segmented heating withering process. Background Art

[0002] In the process of green tea production and processing, it needs to go through three processes: withering, shaping and drying. The quality of withering directly affects the taste of the tea, and the quality of shaping and drying directly affects the shape and quality of the tea. Especially for teas such as Taiping Houkui and West Lake Longjing that have high requirements for shaping effects, the quality of their shaping directly affects the selling price of the tea, so special attention is paid to shaping in tea production and processing.

[0003] The drum-type tea heating and killing device in the prior art usually includes a drum body, a driving assembly for driving the drum body to rotate, and a heating component arranged at the bottom of the drum body and used to heat the inside of the drum body. The inner wall of the drum body is usually fixed with spiral blades for conveying tea leaves from the feed port of the drum body toward the discharge port. The fresh tea leaves must first be quickly heated and then heated and killed for a long time to fully remove the moisture in the tea leaves and achieve tea products that meet the requirements. However, in the drum-type tea heating and killing device in the prior art, the spiral arrangement direction of the spiral blades is not easy to adjust. As the drum body continues to rotate, tea leaves that do not meet the moisture standard may be directly discharged from the discharge port of the drum body, which reduces the quality of tea killing. Therefore, relevant improvements are needed. Summary of the invention

[0004] In order to solve the above problems, the present invention provides an energy-saving and efficient tea segmented heating and withering process.

[0005] The above technical purpose of the present invention is achieved through the following technical scheme: an energy-saving and efficient tea segmented heating and fixing process, the steps are as follows:

[0006] S1, adding fresh tea leaves from the feed of a dedicated tea segmented greening device;

[0007] S2, a heating is performed at the feeding place of the special tea-leaf segmented withering device to quickly heat up the fresh tea leaves;

[0008] S3, performing two-stage heating and heat preservation in the greening section of the dedicated tea-leaf segmented greening device to perform greening treatment on the tea leaves, and discharging the green tea leaves from the discharge port of the dedicated tea-leaf segmented greening device to complete the tea-leaf greening operation;

[0009] A special tea-leaf segmented withering device comprises a base, a mounting plate fixed to the top of the base, a mounting frame fixed to the top of the base, a feeding hopper fixed to the top of the mounting frame, a drum body movably arranged on the top of the mounting plate, and a driving assembly arranged on the base and used to drive the drum body to rotate, one end of the drum body is provided with a feed port for the discharge end of the feeding hopper to pass through, the other end of the drum body is provided with a discharge port, a plurality of spiral conveying members that are in contact with the inner wall of the drum body are provided in the drum body, and an adjusting mechanism for adjusting the extension direction of the spiral conveying members is provided on the drum body.

[0010] By adopting the above technical scheme, the fresh tea leaves are heated at the feed point of the segmented tea withering device, and then enter the withering section of the segmented tea withering device for second-stage heating and insulation. In order to extend the withering time of the tea leaves, the staff only needs to adjust the extension direction of the spiral conveyor through the adjustment mechanism to extend the residence time of the tea leaves in the drum body, thereby reducing the probability of the tea leaves being discharged from the discharge port due to insufficient withering, and improving the tea withering effect and the quality of the tea leaves.

[0011] Furthermore, the adjusting mechanism includes a lifting assembly and a power assembly, the lifting assembly includes a cylinder fixed on the outer wall of the drum body, a movable plate fixed to the end of the piston rod of the cylinder, and a lifting rod penetrating the movable plate and rotatably connected to the movable plate, a battery electrically connected to the cylinder is fixed on the movable plate, one end of the lifting rod penetrates the side wall of the drum body and cooperates with the drum body, one end of the lifting rod located in the drum body is fixed to the middle section of the screw conveyor, the number of the lifting rods is equal to the number of the screw conveyor and the positions correspond one to one, the power assembly is used to drive multiple lifting rods to rotate synchronously, and the screw conveyor is made of steel bars.

[0012] By adopting the above technical scheme, when using the adjustment mechanism to adjust the extension direction of the spiral conveyor, the staff only needs to adjust the piston rod through the cylinder to make the movable plate move toward the side close to the axis of the drum body, and the movable plate drives the spiral conveyor plate to move toward the side close to the axis of the drum body through the lifting rod. Then, the staff can drive multiple lifting rods to rotate synchronously through the power assembly to reset the movable plate. Since the spiral conveyor is made of steel bars, it has a certain elasticity and a certain rigidity. Therefore, when the spiral conveyor is extended in a spiral and pressed against the drum body, the angle adjustment of the spiral conveyor is completed, which is beneficial for the staff to adjust the angle of the spiral conveyor according to actual needs. When the angle of the spiral conveyor is adjusted, the transmission time of the tea leaves through the spiral conveyor will change, which extends the retention time of the tea leaves in the withering section and improves the withering effect.

[0013] Furthermore, the power assembly includes a power motor fixed on the movable plate, a first gear fixedly mounted on the end of the lifting rod, a transmission shaft rotatably mounted on the movable plate, and a second gear fixedly mounted on the transmission shaft and meshing with the first gear. The number of the transmission shafts is equal to the number of the second gears, and the number of the transmission shafts is one less than the number of the lifting rods. The output shaft of the power motor is fixed to one of the ends of the transmission shafts, and the power motor is electrically connected to a battery.

[0014] By adopting the above technical solution, when using a power component to drive multiple lifting rods to rotate synchronously, the staff only needs to start the power motor. After the power motor starts working, it drives the transmission shaft to transmit, and makes the second gear connected to the transmission shaft rotate, and the second gear drives the first gear to rotate, so that multiple lifting rods can all rotate, thereby making multiple spiral conveyors rotate synchronously. After the angle adjustment of the spiral conveyor is completed, stop the adjustment and drive the movable plate to reset.

[0015] Furthermore, the outer side of the spiral conveyor is covered with a food-grade heat-resistant rubber sleeve.

[0016] By adopting the above technical solution, the food-grade heat-resistant rubber sleeve is made of rubber material and has good elastic properties. The setting of the food-grade heat-resistant rubber sleeve makes the spiral conveyor fit more closely with the inner wall of the drum body, reducing the probability of tea getting stuck between the inner wall of the drum body and the spiral conveyor. In addition, the probability of damage to the inner wall of the drum body during the angle adjustment of the spiral conveyor is reduced.

[0017] Furthermore, the outer side of the spiral conveyor is provided with a plurality of arc-shaped sleeves located between the spiral conveyor and the food-grade heat-resistant rubber sleeve.

[0018] By adopting the above technical scheme, a plurality of arc-shaped sleeves are arranged between the spiral conveyor and the food-grade heat-resistant rubber sleeve, and one end of the lifting rod passes through the food-grade heat-resistant rubber sleeve and the arc-shaped sleeve in sequence and is fixed to the spiral conveyor. The arrangement of the spiral conveyor is beneficial to make the food-grade heat-resistant rubber sleeve and the inner wall of the drum body fit more closely after the spiral conveyor is lifted by the lifting rod, thereby reducing the probability of tea leaves getting stuck between the food-grade heat-resistant rubber sleeve and the inner wall of the drum body.

[0019] Furthermore, the driving assembly includes a driving motor fixed on a mounting plate, a driving gear fixed to the end of an output shaft of the driving motor, and a gear ring fixedly sleeved on the drum body and meshing with the driving gear. A support seat is fixed on the top of the mounting plate, a roller is rotatably mounted on the top of the support seat, and an annular ring is fixedly sleeved on the outer side of the drum body and cooperates with the roller in a rolling manner.

[0020] By adopting the above technical solution, the outer ring of the drum body and the roller are in rolling cooperation. When the driving assembly is used to drive the drum body to rotate, the staff only needs to turn on the driving motor, the driving motor works and drives the driving gear to rotate, and the driving gear drives the gear ring meshing with the driving gear and the drum body fixed to the gear ring to rotate, so that the tea leaves in the drum body move toward the discharge port under the action of the spiral conveyor.

[0021] Furthermore, an end cover is provided at one end of the drum body away from the feed hopper, a mounting hole is provided on the side wall of the end cover close to the feed hopper, and a side motor located in the mounting hole is fixed on the drum body.

[0022] By adopting the above technical solution, the side motor drives the end cover to rotate after working, so that the end cover gradually deviates from the discharge port of the drum body, so that the heated and withered tea leaves are discharged from the discharge port, completing the tea unloading operation.

[0023] Furthermore, a fixed sleeve on the outer side of the drum body is provided with a first heating wire for quickly heating the fresh tea leaves that have just entered and a second heating wire for withering the heated tea leaves, and a controller connected to the first heating wire, the second heating wire, the cylinder, the power motor, the drive motor and the side motor is fixed on the base.

[0024] By adopting the above technical solution, the first heating wire and the second heating wire are controlled separately, so as to control the temperature of the drum body in sections, so that the fresh tea leaves just entering the drum body can be heated in time, and heated and sterilized in the drum body at the second heating wire. The controller is set up, and the first heating wire, the second heating wire, the cylinder, the power motor, the drive motor and the side motor are controlled together with the staff.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. In the present application, fresh tea leaves are heated at the feeding place of the segmented tea-withering device, and then enter the withering section of the segmented tea-withering device for second-stage heating and heat preservation. To extend the withering time of the tea leaves, the staff only needs to adjust the extension direction of the spiral conveyor through the adjustment mechanism to extend the residence time of the tea leaves in the drum body, thereby reducing the probability of the tea leaves being discharged from the discharge port due to insufficient withering, and improving the withering effect and quality of the tea leaves;

[0027] 2. In the present application, when the adjustment mechanism is used to adjust the extension direction of the spiral conveyor, the staff only needs to adjust the piston rod through the cylinder to make the movable plate move toward the side close to the axis of the drum body, and the movable plate drives the spiral conveyor plate to move toward the side close to the axis of the drum body through the lifting rod. Subsequently, the staff can drive multiple lifting rods to rotate synchronously through the power assembly to reset the movable plate. Since the spiral conveyor is made of steel bars, it has a certain elasticity and a certain rigidity. Therefore, when the spiral conveyor is extended in a spiral and pressed against the drum body, the angle adjustment of the spiral conveyor is completed, which is beneficial for the staff to adjust the angle of the spiral conveyor according to actual needs. When the angle adjustment of the spiral conveyor is completed, the transmission time of the tea leaves through the spiral conveyor will change, which extends the retention time of the tea leaves in the withering section and improves the withering effect.
