[0002] Tea fermentation is an important part of traditional Chinese tea making, especially in the production of dark tea, oolong tea, black tea and other types of tea. The fermentation process is actually an oxidation process. By controlling humidity and temperature, the chemical composition of the tea leaves undergoes a series of changes, thus forming a unique flavor.

[0003] Prior art: Chinese Patent Publication No. CN104957294A discloses a tea fermentation machine, comprising a frame, a transmission device, a conveying device, a tea inlet connecting frame, a tea inlet hopper, a tea outlet hopper and a tea steaming device, wherein the transmission device is mounted on the left side of the frame; the two ends of the conveying device are mounted on both sides of the frame, and the conveying device is connected to the transmission device; the tea inlet connecting frame is connected to the upper left side of the conveying device by welding; the tea inlet hopper is mounted on the upper end of the tea inlet connecting frame by bolts, and the tea inlet hopper serves as an inlet for tea leaves to ferment; the tea outlet hopper is connected to the lower right side of the conveying device by welding, and the tea outlet hopper serves as an outlet for collecting tea leaves after fermentation; the two ends of the tea steaming device are mounted on both sides of the frame, and the tea steaming device is connected to the conveying device.

[0004] In the above-mentioned prior art, the tea leaves are transported by spiral blades (referred to as spiral auger in this application) so that the tea leaves are turned over in the transport device. However, in this technical solution, the tea leaves cannot be rolled, resulting in the need to roll the tea leaves again when the tea leaves are taken out of the transport device, which makes the operation more inconvenient and causes the fermentation process to be cumbersome and complicated, making it inconvenient for large-scale production.

[0005] Therefore, in order to solve the above problems, a tea production equipment based on tea fermentation is proposed. Summary of the invention

[0006] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a tea production equipment based on tea fermentation. The technical problem to be solved by the present invention is that the tea fermentation equipment in the prior art is unable to roll the tea leaves, resulting in the need to roll the tea leaves when the tea leaves are taken out of the conveying device, which makes the operation more inconvenient and causes the fermentation process to be cumbersome and complicated, making it inconvenient for large-scale production.

[0007] To achieve the above object, the present invention provides the following technical solution: a tea production device based on tea fermentation, comprising a conveying cylinder, and further comprising:

[0008] A support shaft coaxially rotatably connected to the conveying cylinder, wherein the support shaft is driven to rotate by a rotating member installed at the end of the conveying cylinder;

[0009] Rings are respectively connected to both ends of the support shaft, the two rings are respectively defined as a first ring and a second ring, the first ring is fixedly sleeved on the end of the support shaft, and the second ring is slidably sleeved on the support shaft and key-connected with the support shaft;

[0010] A spiral auger is slidably mounted on the periphery of the support shaft, and both ends of the spiral auger are respectively fixed to the periphery of the first ring and the second ring, and when the first ring moves toward the second ring, the spiral auger will produce telescopic deformation along the axial direction of the support shaft, and the spiral surface of the spiral auger is fixed with a convex strip.

[0011] Through the above technical solution, when the second set of rings moves in the direction of the first set of rings, the spiral auger will be compressed, thereby gathering the tea leaves between the spiral augers, and driving the supporting shaft to rotate by the rotating part, so that the spiral auger will stir the tea leaves. At the same time, the convex strips arranged on the spiral surface of the spiral auger will have a kneading effect on the tea leaves, and there is no need to knead the tea leaves after discharging, thereby simplifying the operating steps and enabling large-scale production of tea processing.

[0012] Furthermore, a feeding bin and a discharging bin are respectively provided at two axial ends of the conveying cylinder, and the discharging bin corresponds to the first sleeve ring.

[0013] Through the above technical solution, tea leaves to be fermented are fed into the conveying cylinder from the feeding bin, and the fermented tea leaves can be discharged from the discharging bin through the discharging bin.

[0014] Furthermore, a fixed baffle and a movable baffle are respectively fixedly sleeved on the periphery of the first collar and the second collar, and the outer diameters of the fixed baffle and the movable baffle match the inner diameter of the conveying cylinder.

[0015] Through the above technical solution, a fixed baffle and a movable baffle are provided, so that the tea leaves are always located between the fixed baffle and the movable baffle.

[0016] Furthermore, the rotating member includes a motor seat installed on the end of the conveying cylinder, a stepper motor is installed on the end surface of the motor seat, and an output shaft of the stepper motor is drivingly connected to the support shaft.

[0017] Through the above technical solution, the stepper motor is started, and its output shaft rotates and drives the support shaft to rotate.

[0018] Furthermore, two cylinders are horizontally installed on the outer wall of the motor base, and the cylinder rods of the two cylinders are commonly driven to connect a movable plate. A driving rod is horizontally fixed to the outer wall on the other side of the movable plate, and one end of the driving rod penetrates into the conveying cylinder and contacts with the end face of the movable baffle, and the driving rod slides freely in the conveying cylinder.

[0019] Through the above technical solution, the cylinder rod of the cylinder is extended, so that the cylinder drives the driving rod to move toward the direction of the conveying cylinder, and the driving rod presses against the end surface of the movable baffle plate, so that the movable baffle plate drives the movable ring to move toward the direction of the fixed ring, so that the spiral auger is in a compressed state.

[0020] Furthermore, a ball is rotatably embedded in one end of the driving rod that penetrates into the conveying cylinder, and the ball is in rolling contact with the end surface of the movable baffle.

[0021] Through the above technical solution, the balls roll on the end surface of the movable stopper, so that when the movable stopper rotates, the friction and wear between the end surface of the movable stopper and the end of the driving rod is small.

[0022] Furthermore, the thickness of the spiral auger decreases gradually in the direction away from the second ring.

[0023] Through the above technical solution, the compression deformation amount of the spiral auger on the side away from the movable baffle is not much different from the compression deformation amount of the other side thereof.

[0024] Furthermore, a joint is fixedly connected to one end of the support shaft adjacent to the first sleeve ring, a transition hole communicating with the joint is opened inside the support shaft, a plurality of blowing seats are fixedly connected to the periphery of the support shaft, the blowing seats are hollow inside and communicate with the transition hole, and an air outlet is opened on the end face of the blowing seat.

[0025] Through the above technical solution, air is transported from the joint to the transition hole, and then the air is transported from the air outlet of the blowing seat to the tea leaves in the rolling process, thereby increasing the mixing degree of oxygen in the air and the juice produced by rolling the tea leaves, thereby improving the fermentation efficiency of the tea leaves.

[0026] Furthermore, the blowing seat is provided with an air outlet adjustment member, and the air outlet adjustment member includes a rotating shaft coaxially penetrated in the blowing seat, one end of the rotating shaft penetrated into the blowing seat is fixedly mounted with a rotating disk, the upper end surface of the rotating disk is in contact with the inner top wall of the inner cavity of the blowing seat, and the end surface of the rotating disk is provided with a through groove corresponding to the air outlet, the outer diameter of the rotating disk is smaller than the inner diameter of the blowing seat, and the periphery of the rotating disk is fixedly sleeved with a volute spring, two ends of the volute spring are respectively fixedly connected to the inner wall of the blowing seat and the periphery of the rotating disk, a toggle rod is horizontally penetrated by the periphery of the blowing seat, the toggle rod slides freely on the blowing seat, the toggle rod is in contact with the surface of the spiral auger, and the end of the periphery of the toggle rod that penetrates into the blowing seat is provided with a rack portion, and the periphery of the rotating shaft is provided with a gear portion meshing with the rack portion.

[0027] Through the above technical solution, when the spiral auger is compressed, the end of the toggle rod will be driven by the spiral auger to move toward the inner side of the blowing seat, so that the rack part and the gear part are meshed, and then the rotating shaft is driven to rotate. When the rotating shaft rotates, it will drive the rotating disk to rotate, so that the through groove and the air outlet are in a through state. In addition, the size of the through area is related to the compression degree of the spiral auger, so that when the compression amplitude of the spiral auger is large, that is, the tea leaves are gathered more tightly, it is necessary to increase the air intake to ensure that the air can smoothly enter the tea leaves, thereby better fermenting the tea leaves.

[0028] Furthermore, a retaining ring is coaxially fixed to the inner cavity of the blowing seat, and an installation space is enclosed between the end surface of the retaining ring and the inner wall of the inner cavity of the blowing seat. The rotating disk is engaged in the installation space and rotates freely.

[0029] Through the above technical solution, the retaining ring limits the rotating disk, so that the rotating disk is rotatably connected in the blowing seat.

[0030] Technical effects and advantages of the present invention:

[0031] 1. When the second set of rings moves toward the first set of rings, the spiral auger is compressed, thereby gathering the tea leaves between the spiral auger, and the supporting shaft is driven to rotate by the rotating member, so that the spiral auger stirs the tea leaves, and at the same time, the convex strips arranged on the spiral surface of the spiral auger have a kneading effect on the tea leaves, so that there is no need to knead the tea leaves after discharging, simplifying the operation steps, so that tea processing can be mass-produced;

[0032] 2. By setting the air to be transported from the joint to the transition hole, and then the air is transported from the air outlet of the blowing seat to the tea leaves in the rolling process, the mixing degree of oxygen in the air and the juice from the tea leaves is increased, thereby improving the fermentation efficiency of the tea leaves;

[0033] 3. When the spiral auger is compressed, the end of the toggle rod will be driven by the spiral auger to move toward the inner side of the blowing seat, so that the rack part and the gear part are meshed, thereby driving the rotating shaft to rotate. When the rotating shaft rotates, it will drive the rotating disk to rotate, thereby making the through groove and the air outlet in a through state. In addition, the size of the through area is related to the compression degree of the spiral auger, so that when the compression amplitude of the spiral auger is large, that is, the tea leaves are gathered more tightly, and the air intake volume needs to be increased at this time to ensure that the air can smoothly enter the tea leaves, thereby better fermenting the tea leaves.

[0051] Working principle of the present invention:

[0052] Feeding: Workers feed the tea leaves to be fermented from the feeding bin 3 into the conveying cylinder 1, start the stepper motor 6, the output shaft of the stepper motor 6 rotates, and drives the support shaft 8 to rotate. During the rotation of the support shaft 8, the spiral auger 17 can evenly transport the tea leaves fed into the conveying cylinder 1 to various places in the conveying cylinder 1. At this time, since the spiral auger 17 is not subjected to the axial force along the support shaft 8, the spiral auger 17 does not produce elastic compression deformation, so the tea leaves in the conveying cylinder 1 are relatively loose, and the convex strips 11 have no kneading effect on the tea leaves. During the feeding process, the discharge bin 2 is in a closed state, and after the feeding is completed, the mouth of the feeding bin 3 is also closed, so that the conveying cylinder 1 is basically in a closed state (a small amount of air is allowed to enter the conveying cylinder 1);

[0053] Fermentation: Start the stepper motor 6, the output shaft of the stepper motor 6 drives the support shaft 8 to rotate, and when rotating, the cylinder 5 is started synchronously, and the cylinder rod of the cylinder 5 is extended to drive the movable plate 15 to move toward the direction of the conveying cylinder 1, so that the ball 16 at the end of the driving rod 4 presses against the end surface of the movable baffle 13, so that the movable baffle 13 moves away from the feeding bin 3, so that the second ring 14 slides on the support shaft 8, so that the second ring 14 moves in the direction of the first ring 9, and the spiral auger 17 elastically contracts, so as to push the conveying cylinder 1 is gathered, and with the rotation of the support shaft 8, the spiral auger 17 can stir the tea leaves. During the stir-frying process, the convex strips 11 on the surface of the spiral auger 17 will produce a rolling effect on the tea leaves. When the spiral auger 17 is compressed, the convex strips 11 will move in multiple directions and deform synchronously with the spiral auger 17, so that the convex strips 11 can roll the tea leaves. When rolling, the convex strips 11 can destroy the cell walls of the tea leaves, so that the juice in the tea leaves cells seeps out, so that the juice contacts oxygen and the fermentation effect is better.

[0054] Oxidation: When the spiral auger 17 is in a compressed state, the end of the toggle rod 19 will be squeezed by the spiral auger 17, so that the toggle rod 19 slides toward the inner side of the blowing seat 12. When sliding, the rack part 26 on the toggle rod 19 meshes with the gear part 24 to rotate, thereby driving the rotating shaft 23 to rotate. When the rotating shaft 23 rotates, the rotating disk 27 will rotate, so that the through groove 28 and the air outlet 21 begin to penetrate, so that the air enters the transition hole 20 of the support shaft 8 from the joint 18, and is blown into the gathered tea leaves from the inner cavity of the blowing seat 12, the through groove 28 and the air outlet 21, so that the oxygen in the air contacts the juice squeezed out of the tea leaves, so that the tea leaves can be fermented more effectively. At the same time, the rotation of the rotating disk 27 will cause the volute spring 22 to contract and accumulate elastic potential energy, and then the cylinder rod of the cylinder 5 will shorten, and the spiral auger 17 will The elastic deformation is restored, so that the spiral auger 17 changes from an elastically contracted state to an elastically expanded state, so that the spiral auger 17 pushes the second ring 14 to move in the direction of the motor seat 7, and the movable baffle 13 pushes the driving rod 4 to move in the direction of the motor seat 7. At this time, the tea leaves in the conveying cylinder 1 change from a gathered state to a loose state, and the push force on the toggle rod 19 caused by the surface of the spiral auger 17 disappears. Under the release of the elastic potential energy of the volute spring 22, the rotating disk 27 rotates in the opposite direction, so that the through groove 28 and the air outlet 21 are staggered. At this time, air cannot enter the conveying cylinder 1 from the air outlet 21, thereby causing the tea leaves to ferment. After the fermentation is completed, the stepper motor 6 is started again, and the output shaft of the stepper motor 6 drives the supporting shaft 8 to rotate, so that the spiral auger 17 can drive the fermented tea leaves to the discharge bin 2, open the discharge bin 2, and allow the tea leaves to fall from the discharge bin 2.
