Technical Field
[0001] This invention relates to the field of black tea processing equipment technology, specifically to an aerobic fermentation device for black tea processing. Background Technology
[0002] The aerobic fermentation device for black tea processing is a key material handling equipment in the black tea production process. The fermentation process is the core process for the formation of black tea quality. The fermentation device is mainly used to hold the rolled tea leaves and physically turn the tea leaves in a specific temperature, humidity and oxygen environment, so as to promote the oxidation reaction of the chemical substances inside the tea leaves, thereby forming the specific color and taste of black tea.
[0003] Most existing black tea fermentation machinery uses a horizontal drum structure for dynamic fermentation. In actual industry production applications, batches of tea leaves are fed into the drum chamber. The equipment relies on a motor to drive the entire drum chamber to rotate mechanically. The tea leaves inside the chamber are carried to a high position as the drum wall rotates and then slide down along the direction of gravity. Through this continuous overall tumbling motion, the tea pile inside can alternately contact with the air to maintain the physical conditions required for fermentation.
[0004] The drawback of existing technology is that such fermentation devices cannot simultaneously screen the materials during the tumbling fermentation of tea leaves. After the initial rolling process, tea leaves produce broken tea powder and fine impurities. In the existing closed fermentation chamber, these fine fragments are always mixed with the normal strip-shaped tea leaves and tumble together. Under the high humidity of the fermentation environment, they adhere to the surface of the shaped tea leaves. This structural defect, which makes it impossible to physically separate impurities simultaneously during the fermentation and tumbling stage, directly leads to a decrease in the overall purity of the tea leaves after fermentation, affecting the processing quality of the finished black tea. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide an aerobic fermentation device for black tea processing, which addresses the shortcomings of the prior art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an aerobic fermentation device for black tea processing, including a support frame and a fermentation tank, wherein the fermentation tank is fixedly placed on the support frame for support and is used for black tea fermentation, and further includes: The feed baffle and discharge baffle are respectively installed on the right side of the outer wall of the fermentation tank, and are used to add and remove tea leaves into the fermentation tank; Two waste baffles are installed on the lower outer wall of the fermentation tank to remove tea impurities separated from the fermentation tank; A rotating mechanism, located inside the fermentation tank, is used to rotate and agitate the tea leaves. The agitating mechanism, located inside the fermentation tank, remains stationary relative to the rotating mechanism to agitate the tea leaves; The dispersing mechanism, located inside the fermentation tank, is used to agitate the tea leaves as it rotates with the rotating mechanism. The rotating mechanism includes: The separator is located inside the fermentation tank, with openings at both ends and attached to the inner walls of the fermentation tank. The outer wall of the separator has through holes for separating impurities from the tea leaves. A rotating component, located inside the separation cylinder, is used to drive the separation cylinder to rotate; A support assembly is provided on the outer wall of the separation cylinder and the inner wall of the fermenter to support the rotation of the separation cylinder on the inner wall of the fermenter.
[0007] Preferably, the support component includes: Multiple fixing rings are fixedly connected to the inner wall of the fermenter; The separation cylinder is partially separated into two sections. Multiple annular rails are fixedly connected in pairs to the outer walls of two separating cylinders, and multiple spherical rods are slidably connected to the outer wall of each annular rail. The end of each spherical rod away from the annular rail is connected to the inner wall of the fixed ring.
[0008] Preferably, the rotating component includes: The drive shaft and rotating ring are respectively located on both sides of the interior of the fermenter; Multiple fixed rods, four in a group, are set on both sides of the inner wall of the fermenter, and their two ends are fixedly connected to the drive shaft, the rotating ring and the inner wall of the fermenter, respectively, to drive the separation cylinder to rotate; The separation cylinder is equipped with an isolation cylinder inside, which is used to isolate the tea leaves that are moved upward by the separation cylinder and separate them to both sides. A fixed shaft is fixedly connected to the outer wall of the isolation cylinder, and the fixed shaft rotates within the inner wall of the rotating ring. One end of the drive shaft has a movable ring that extends outward through the fermenter and is used to drive the separation cylinder to rotate. The other end of the drive shaft is rotatably connected to the outer wall of the separation cylinder through a bearing.
[0009] Preferably, the actuating mechanism includes: An arc-shaped fixing plate is fixedly connected to the inner wall of the fermenter and located in the middle of the separation cylinder; Two arc-shaped scrapers are symmetrically arranged and attached to the inner wall of the separator, and are connected by two air pipes respectively. Multiple levers, one or two at a time, are fixedly connected to the outer wall of the arc-shaped scraper to agitate the tea leaves inside the separation cylinder.
[0010] Preferably, the actuating mechanism further includes: Multiple deflection plates are rotatably connected to the outer wall of lever one in pairs. Each deflection plate is connected to lever one via a tension spring away from the hinge point, which is used to pull the deflection plate to deflect to one side of lever one. Multiple levers are fixedly connected to two adjacent deflection plates, and follow the deflection plates to expand the range of movement; The lever has multiple air holes, and the air holes blow the airflow to deflect it to one side of the deflector plate. The vents are connected to air tubes for gas flow.
[0011] Preferably, the dispersing mechanism includes: Two sliders are respectively slidably fitted onto the outer walls of the fixed rods on both sides; Two springs are fitted onto the outer wall of the fixed rod and push the two sliders downwards; A connecting rod is fixedly connected between two sliders, and a plurality of spaced-apart dispersing plates are fixedly sleeved on the outer wall of the connecting rod. The dispersing plates are attached to the inner wall of the separating cylinder and are used to disperse the tea leaves as the separating cylinder rotates.
[0012] Preferably, the dispersing plate is arranged with comb-like teeth, and when the dispersing plate rotates, it is staggered relative to the two sets of levers arranged in a row.
[0013] Preferably, the outer wall of the isolation cylinder has multiple airflow holes, and a compression mechanism is provided inside the separation cylinder for compressing gas to flow into the separation cylinder. The compression mechanism includes: Multiple arc-shaped blocks are fixedly connected to both sides of the outer wall of the separator cylinder; Two abutting rods are fixedly connected to the top of the two middle dispersing plates and abut against the outer wall of the separation cylinder; Multiple compression rods are symmetrically arranged vertically and slide inside the separation cylinder, and are pushed into the separation cylinder by a contact rod; An air bladder is provided inside the separation cylinder. When the compression rod moves into the separation cylinder, the compressed air bladder releases gas and flows through the airflow hole. When the compression rod slides out of the separation cylinder, the gas in the air bladder is restored.
[0014] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This aerobic fermentation device for black tea processing uses a separation cylinder with multiple through holes inside the fermentation tank and a waste baffle installed at the bottom of the fermentation tank. When the separation cylinder rotates and turns the tea leaves inside the tank under the drive of external equipment, the fine fragments mixed in with the black tea can fall to the bottom of the fermentation tank by gravity through the through holes as the material moves. Then, the waste baffle is opened to discharge the separated impurities from the equipment. This achieves physical screening of tea impurities while the black tea is tumbling and fermenting, and improves the overall purity and processing quality of the fermented tea.
[0015] 2. This aerobic fermentation device for black tea processing uses a relatively stationary agitation mechanism and a dispersing mechanism that rotates with the separation cylinder inside the fermentation tank. This causes the comb-shaped dispersing plates rotating with the cylinder to temporarily intersect and generate relative displacement via the bottom lever, mechanically dispersing tea clumps that are prone to clump together during rotation. Combined with a deflection plate that is expanded by pneumatic thrust, this amplifies the physical disturbance to the tea pile. As a result, the device forcibly turns over the wall-adhering material and breaks up clumps during fermentation, while ensuring that oxygen fully penetrates into the tea leaves to promote uniform fermentation.
[0016] 3. This aerobic fermentation device for black tea processing, by setting an air bladder inside the separation cylinder and connecting the exhaust port with the airflow hole, causes the slider to slide back and forth along the fixed rod due to the periodic change in the direction of gravity when the equipment rotates. This causes the contact rod to intermittently push the compression rod to squeeze the air bladder to exhaust gas, which then enters the fermentation chamber through the airflow hole to supply oxygen. Subsequently, the slider resets under the action of gravity and spring, causing the air bladder to rebound and draw in air. This achieves the use of the gravity change of the equipment's own rotation to drive the air bladder to contract and expand, and to complete the forced convection and gas exchange inside the fermentation chamber without an external power source.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example
[0020] Please see Figure 1-10 This invention provides an aerobic fermentation device for black tea processing, including a support 1 and a fermentation tank 2. The fermentation tank 2 is a horizontal cylindrical shape and is fixedly placed on the support 1 for support. The fermentation tank 2 is used for fermenting black tea. A feed baffle 3 and a discharge baffle 4 are installed on the right side of the outer wall of the fermentation tank 2. The feed baffle 3 and the discharge baffle 4 are used to add tea leaves to be fermented into the fermentation tank 2 and to remove the tea leaves after fermentation. Two waste baffles 5 are installed at the bottom of the outer wall of the fermentation tank 2. The waste baffles 5 are used to remove tea impurities separated from the fermentation tank 2.
[0021] The fermenter 2 is equipped with a rotating mechanism 6, which includes a separation cylinder 61. The separation cylinder 61 is located inside the fermenter 2 and has openings at both ends that fit against the inner walls of the fermenter 2. The outer wall of the separation cylinder 61 has a through hole. The separation cylinder 61 is separated into two sections. The fermenter 2 is equipped with a support assembly 63 and a rotating assembly 62. The support assembly 63 includes multiple fixing rings 631 that are fixedly connected to the inner wall of the fermenter 2. Multiple annular rails 633 are fixedly connected to the outer walls of the two sections of the separation cylinder 61, arranged in pairs. Multiple spherical rods 632 are slidably connected to the outer wall of each annular rail 633. The end of the spherical rod 632 away from the annular rail 633 is connected to the inner wall of the fixing ring 631 to support the rotation of the separation cylinder 61 inside the fermenter 2.
[0022] The rotating assembly 62 includes a drive shaft 621 and a rotating ring 623 respectively located at the center of the two sides inside the fermenter 2. Multiple fixing rods 622 are provided on both sides of the inner wall of the fermenter 2. The fixing rods 622 are arranged in a circumferential array of four rods. The two ends of the fixing rods 622 are fixedly connected to the drive shaft 621, the rotating ring 623 and the inner wall of the fermenter 2 respectively.
[0023] Working principle: In the early stage of fermentation, the operator feeds the kneaded black tea into the separation cylinder 61 through the feed baffle 3, starts the external motor to drive the drive shaft 621 to rotate, and the drive shaft 621 drives the rotating ring 623 and the separation cylinder 61 to rotate synchronously in the fermentation tank 2 through the fixed rod 622. During the rotation, the ring rail 633 slides on the fixed spherical rod 632, and the broken tea leaves mixed in fall into the bottom of the fermentation tank 2 through the through hole on the outer wall of the separation cylinder 61 and are discharged through the waste baffle 5. Example
[0024] Please see Figure 1-10 Based on the above embodiment 1, the fermentation tank 2 is equipped with a toggle mechanism 7 and a dispersing mechanism 8. The toggle mechanism 7 remains stationary when it rotates relative to the rotating mechanism 6.
[0025] The actuating mechanism 7 includes an arc-shaped fixing plate 71 fixedly connected to the bottom of the inner wall of the fermenter 2. The arc-shaped fixing plate 71 passes through the gap between the middle of the separation cylinder 61 and extends into the separation cylinder 61. Two arc-shaped scrapers 73 are symmetrically arranged and attached to the inner wall of the separation cylinder 61, and are respectively connected to the external gas supply equipment through two air pipes 72. Multiple levers 74 are fixedly connected to the outer wall of the arc-shaped scraper 73. The levers 74 are distributed in pairs. Multiple deflection plates 75 are rotatably connected to both sides of the outer wall of the levers 74. The side of each deflection plate 75 away from the hinge is connected to the lever 74 through a tension spring 76. Multiple levers 77 are fixedly connected to adjacent deflection plates 75. Multiple air holes are opened on the levers 74. The air holes are connected through the air pipes 72 for spraying gas outward. The dynamic pressure of the sprayed airflow drives the deflection plate 75 to deflect to one side against the elastic force of the tension spring 76.
[0026] The airflow pressure entering the trachea 72 must satisfy the following torque balance relationship to ensure that the deflector plate 75 deploys: , In the formula: The aerodynamic thrust generated by the airflow ejected from the vent on the deflector plate 75; The distance from the point of application of the aerodynamic thrust to the hinge point of the deflector plate at 75°. The tension of the spring is 76. This is the distance from the connection point of the tension spring 76 to the hinge point of the deflection plate 75.
[0027] The dispersing mechanism 8 includes two sliders 81 that are slidably sleeved on the outer walls of the two fixed rods 622. Two springs 82 are sleeved on the outer walls of the fixed rods 622. The springs 82 push the sliders 81 to move downward. A connecting rod 83 is fixedly connected between the two sliders 81. A plurality of dispersing plates 84 are fixedly sleeved on the outer walls of the connecting rods 83. The dispersing plates 84 are arranged in a comb-like tooth structure and fit against the inner wall of the separating cylinder 61. When the dispersing plates 84 rotate with the separating cylinder 61 to the position of the bottom arc-shaped scraper 73, the comb-like teeth of the dispersing plates 84 and the stationary lever 74 are spatially interleaved and displaced.
[0028] Working principle: The rotating separator 61 carries the tea leaves at the bottom to a higher position. The arc-shaped scraper 73, which is stationary at the bottom, scrapes off the tea leaves that are attached to the wall. The external air supply device delivers air through the air pipe 72 to the inside of the lever 74 and sprays it out through the air hole. When the air pressure meets the balance relationship, the deflection plate 75 is deflected outward by the air pressure, which expands the range of physical disturbance to the tea leaves. When the dispersing plate 84, which rotates with the separator 61, passes the stationary lever 74, the two are relatively misaligned, which disperses the tea leaves that have gathered into clumps. Example
[0029] Please see Figure 1-10 Based on the above embodiment 2, an isolation cylinder 9 is coaxially arranged inside the separation cylinder 61, and multiple airflow holes are opened on the outer wall of the isolation cylinder 9. A compression mechanism 10 is arranged inside the isolation cylinder 9.
[0030] The compression mechanism 10 includes multiple arc-shaped blocks 101 fixedly connected to both sides of the outer wall of the separation cylinder 61. Two abutting rods 102 are fixedly connected to the top of the two middle dispersing plates 84. The ends of the abutting rods 102 abut against the outer wall surface of the separation cylinder 61. Multiple compression rods 103 are arranged symmetrically and slidably connected in the radial direction of the separation cylinder 61. An airbag support is fixedly installed inside the separation cylinder 61. The airbag is installed on the airbag support. The exhaust port of the airbag is connected to the airflow hole on the isolation cylinder 9. A compression push plate is fixedly connected to the end of the compression rod 103 near the airbag. When the compression rod 103 moves to the inside of the separation cylinder 61, it compresses the airbag through the compression push plate, forcing the airbag to release gas. The gas flows to the outside of the isolation cylinder 9 through the airflow hole. When the compression rod 103 slides back to the outside of the separation cylinder 61, the airbag rebounds and expands, generating negative pressure to draw in air.
[0031] Working principle: The separating cylinder 61 drives the internal fixed rod 622 to rotate. During the rotation, the direction of gravity on the slider 81 and the dispersing mechanism 8, which are slidably sleeved on the fixed rod 622, changes continuously relative to the fixed rod 622. When the fixed rod 622 rotates to the vertical upper stop position, the condition for the slider 81 to slide towards the center must satisfy the following static critical state equation: , In the formula: The total mass of the disintegration mechanism 8 and the slider 81; It is the acceleration due to gravity; The component of the tangential working resistance of the tea leaves on the dispersing plate 84; The frictional force between slider 81 and fixed rod 622; The spring constant of spring 82; This refers to the displacement of the slider 81 relative to the fixed rod 622 when the compression rod 103 reaches its maximum exhaust stroke.
[0032] As the slider 81 reciprocates with the rotation of the separating cylinder 61, it synchronously drives the contact rod 102 to produce radial displacement. When the slider moves towards the center, the contact rod 102 moves inward and pushes the compression rod 103, which in turn squeezes the airbag to expel air. When the slider 81 returns to its original position, the contact rod 102 retracts, and the airbag rebounds to draw in air. The change in the gravitational field of the rotating equipment is used to complete the forced convection of the internal gas.
