Abstract
Description
Technical Field
[0001] This invention relates to the field of black tea processing equipment technology, specifically to a black tea fermentation device with temperature-controlled lamps for uniform fermentation. Background Technology
[0002] The black tea fermentation device is the core processing equipment in the initial processing of black tea. The fermentation process is a key stage in the formation of the intrinsic quality of black tea. Its main function is to promote the enzymatic oxidation and polymerization of polyphenols in the tea leaves after rolling under specific environmental conditions, thereby forming the unique red liquor and red leaves characteristics, as well as the aroma and taste of black tea.
[0003] In existing black tea production, the fermentation process is typically carried out in a fixed fermentation room or basic fermentation tank. In practice, production staff spread the kneaded tea leaves onto fermentation trays or fixed fermentation beds, placing them in a relatively enclosed fermentation space. During fermentation, the air in the entire space is centrally heated using warm air blowers or steam pipes provided in the workshop to maintain the basic temperature required for tea fermentation. Once the batch of tea has completed its entire fermentation cycle in a fixed location, it is then moved out and transferred to the next process step.
[0004] The shortcomings of existing technologies lie in the fact that traditional static spreading fermentation methods are intermittent batch production. After kneading, the tea leaves lack an automated continuous flow and transfer structure in the fermentation chamber. Not only does the material flow rely on manual intervention and have low turnover efficiency, but existing equipment, which relies on macroscopic air heating of the entire fermentation chamber space, is prone to creating temperature dead zones. It is impossible to directly and continuously radiate heat to the surface of the tea leaves in specific locations, resulting in inconsistent heating conditions and ambient temperatures in different areas of the tea leaves. This makes it difficult to provide a stable and controllable uniform fermentation environment, ultimately causing deviations in the degree of fermentation of the same batch of black tea and making it difficult to guarantee the basic fermentation quality of black tea. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a black tea fermentation device with uniform fermentation by temperature control lamp, 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: a temperature-controlled lamp uniform fermentation device for black tea, including a tea box, and further comprising: A fermentation box, installed on one side of the outer wall of the tea box, is used for tea fermentation; The conveying mechanism is installed inside the tea box on one side and extends outward through the tea box on the other side, located below the fermentation box, to convey the tea leaves inside the tea box outward. A conveying device is installed below the conveying mechanism to circulate the tea leaves conveyed by the conveying mechanism back into the tea box; The tea-dispersing mechanism is located on one side of the inner wall of the tea box to beat and disperse the returning tea leaves. The agitating mechanism is located on the other side of the inner wall of the tea box and above the conveying mechanism. It is used to evenly convey the tea outward and agitate the tea leaves. The conveying mechanism includes: Multiple rotating shafts are set at equal intervals and installed on the inner wall of the tea box and fermentation box; Each shaft has pulleys fixedly fitted on both sides of its outer wall, and belts are connected to the outer walls of the pulleys on the front and rear sides for synchronous rotation of multiple shafts. Multiple rollers are fixedly sleeved on the outer wall of each rotating shaft, and the outer wall of the rollers is connected to a conveyor belt for conveying tea in the tea box. The conveyor belt is located at a rectangular hole on one side of the tea box.
[0007] Preferably, the inner wall of the tea box is fixedly connected to a gathering hopper for gathering tea leaves towards the top of the conveyor belt; The bottom of the gathering hopper is fixedly connected to a U-shaped baffle, and the bottom of the U-shaped baffle is in contact with the top of the conveyor belt. The opening side of the U-shaped baffle is set at the rectangular hole, which is used to drive the tea leaves to the outer wall of the tea box.
[0008] Preferably, the inner wall of the fermentation box is fixedly connected to the front and rear sides with fixing plates respectively, and the bottom of the fixing plates is attached to the top of the conveyor belt to limit the tea leaves. The top of the fermentation chamber is equipped with multiple equally spaced light strips for illuminating the tea leaves on the conveyor belt.
[0009] Preferably, the dispersing mechanism includes: A feeding ramp is fixedly connected to one side of the inner wall of the tea box, and the inner wall of the tea box has a feeding hole located above the feeding ramp for guiding backflowing tea leaves. The rotating rod is rotatably connected to the inner wall of the fermentation tank via bearings and is located below the feeding sloping plate; Multiple striking rods are equidistantly connected to the outer wall of the rotating rod, used to agitate the backflowing tea leaves that slide off the feeding inclined plate when rotating; The baffle is fixedly connected to the inner wall of the fermentation box and works in conjunction with the beater to block and break up the tea leaves.
[0010] Preferably, the dispersing mechanism further includes: Multiple movable rods, in pairs, move through the gathering hopper and the U-shaped baffle, and are located on the front and back sides of the tea box; Two racks are fixedly connected to the tops of the front and rear movable rods, respectively, and mesh with gears fixedly sleeved on the outer wall of the rotating rod; Two contact plates are fixedly connected to the bottom of the front and rear movable rods, and the bottom of the contact plates is equipped with telescopic rods to push the contact plates to move upward. Two cams are fixedly connected to the front and rear ends of the left rotating shaft, and the outer wall of the cams is attached to the outer wall of the contact plate to push the contact plate downward.
[0011] Preferably, the actuating mechanism includes: The slide rod is slidably connected to a sliding cavity opened at the bottom of the gathering hopper; Multiple levers are equidistantly and fixedly connected to the lower outer wall of the slide bar, with the bottom of the levers extending downwards and fitting against the top of the conveyor belt, used to divide the tea leaves on the conveyor belt into equidistant tea leaf piles.
[0012] Preferably, the actuating mechanism further includes: Two fixing sleeves are installed in the mounting cavity of one of the rotating shafts and are arranged symmetrically front and back; Multiple connecting rods, in pairs, are symmetrically arranged on the outer wall of the fixing sleeve to connect the fixing sleeve to the inner wall of the tea box; The reciprocating lead screw is installed in the mounting cavity of the rotating shaft and slides back and forth on the inner wall of the fixed sleeve; Two synchronizing rods are fixedly connected to the front and rear ends of the slide rod, respectively, and the end of the synchronizing rod away from the slide rod is connected to the reciprocating lead screw to push the slide rod to move back and forth.
[0013] Preferably, a ball block is fixedly connected to the inner wall of the mounting cavity of the rotating shaft. The ball block is sleeved in the outer wall groove of the reciprocating screw. When the rotating shaft rotates, it drives the ball block to rotate, thereby pushing the reciprocating screw to move back and forth.
[0014] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This temperature-controlled lamp-based uniform fermentation device for black tea uses a conveyor mechanism consisting of rollers and a conveyor belt connected by a rotating shaft and pulleys between the tea box and the fermentation box. The tea leaves from the gathering hopper are spread flat on the conveyor belt and continuously transported into the fermentation box. In addition, multiple equidistant lamp strips installed on the top of the fermentation box continuously illuminate and radiate heat to the surface of the tea leaves moving on the conveyor belt below. This achieves automated and continuous circulation of black tea materials and provides a stable and controllable fermentation environment, thereby ensuring the basic fermentation quality of black tea.
[0015] 2. This temperature-controlled lamp-based uniform fermentation device for black tea uses a dispersing mechanism located below the feed hole of the tea box. A cam at the end of the rotating shaft rotates and presses against a contact plate, causing a movable rod and rack to move linearly back and forth against the elasticity of the telescopic rod. The linear movement of the rack drives the gears and rotating rods meshing with it to rotate and oscillate back and forth. This causes the striking rod on the rotating rod, in conjunction with a baffle fixed to the inner wall, to continuously strike and compress the clumps of tea leaves sliding down the feed inclined plate. This effectively disperses the tea leaves that have clumped together during the conveying and return process, ensuring that the material enters the next process in a loose state.
[0016] 3. This temperature-controlled lamp uniform fermentation black tea fermentation device uses a toggle mechanism set above the conveying mechanism and a ball-bearing slider rotating inside the hollow shaft to apply thrust along the bidirectional spiral groove on the outer wall of the reciprocating screw. This forces the reciprocating screw, which is restricted by the fixed sleeve and cannot rotate on its own, to drive the synchronous rod and the slide rod to slide horizontally back and forth at the bottom of the gathering hopper. This causes multiple toggle rods at the bottom of the slide rod to move laterally above the conveyor belt and flatten the piled tea leaves. This achieves the goal of spreading the tea leaves into a uniform material layer before they enter the fermentation box, thereby improving the consistency of the lamp strip's heat radiation penetration.

[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.
[0020] Please see Figure 1-8 This invention provides a temperature-controlled lamp uniform fermentation device for black tea, including a tea box 1 that provides support and storage space, a fermentation box 2 installed on one side of the outer wall of the tea box 1, the interior of the fermentation box 2 forming a chamber for providing a fermentation environment for black tea, a conveying mechanism 3 provided between the tea box 1 and the fermentation box 2, one side of the conveying mechanism 3 installed inside the tea box 1, the other side of the conveying mechanism 3 extending outward through the tea box 1 and located below the fermentation box 2, an external circulating conveying device provided below the conveying mechanism 3, the circulating conveying device being able to circulate the tea output from the conveying mechanism 3 back to the top of the tea box 1.
[0021] The conveying mechanism 3 includes multiple rotating shafts 31 arranged at equal intervals. The two ends of the rotating shafts 31 are rotatably mounted on the front and rear inner walls of the tea box 1 and the fermentation box 2 respectively through bearings. Each rotating shaft 31 has a pulley 32 fixedly sleeved on both the front and rear sides of its outer wall. Adjacent pulleys 32 on the same side are connected by a belt 33 to ensure that when the external drive motor drives one of the rotating shafts 31 to rotate, all rotating shafts 31 rotate synchronously. A roller 34 is fixedly sleeved on the outer wall of the middle part of each rotating shaft 31. The outer walls of the rollers 34 are connected to a conveyor belt 35. A rectangular hole is opened on the side wall of the tea box 1 near the fermentation box 2. The conveyor belt 35 passes through the rectangular hole for conveying.
[0022] A gathering hopper 5 is fixedly connected to the inner wall of the tea box 1. A U-shaped baffle 6 is fixedly connected to the bottom of the gathering hopper 5. The bottom edge of the U-shaped baffle 6 is in contact with the top working surface of the conveyor belt 35. The opening side of the U-shaped baffle 6 is directly opposite the rectangular hole on the side wall of the tea box 1, so that the tea leaves are output outward along the movement direction of the conveyor belt 35. Fixing plates 7 are fixedly connected to the front and rear sides of the inner wall of the fermentation box 2. The bottom of the fixing plates 7 is in contact with the top of the conveyor belt 35 to limit the material of the tea leaves. Multiple equally spaced light strips 8 are installed on the top inner wall of the fermentation box 2 to irradiate the tea leaves on the conveyor belt 35 with light and heat.
[0023] Working principle: The black tea to be fermented enters the tea box 1, is guided by the gathering hopper 5 to the U-shaped baffle 6 at the bottom, and is spread flat on the conveyor belt 35. The external drive motor is started, and the rotating shaft 31 rotates synchronously through the pulley 32 and belt 33, driving the roller 34 and conveyor belt 35 to run. The conveyor belt 35 transports the tea from the inside of the tea box 1 through the rectangular hole to the fermentation box 2. Inside the fermentation box 2, the fixing plate 7 restricts the spread width of the tea, and the light strip 8 at the top radiates the surface of the tea. The tea is transported to the outside of the fermentation box 2 and falls into the circulating conveyor below to get out of the fermentation box 2. During the reflux process, it is fully exposed to oxygen and is sent back to the top of the tea box 1 to enter the next fermentation cycle. Example
[0024] Please see Figure 1-8 Based on the above embodiment 1, a dispersing mechanism 4 is provided on one side of the inner wall of the tea box 1. The dispersing mechanism 4 includes a feeding inclined plate 41 fixedly connected to the inner wall of the tea box 1. A feeding hole is opened on the side wall of the tea box 1 above the feeding inclined plate 41 to receive the tea returned by the circulating conveyor. A rotating rod 43 is provided below the feeding inclined plate 41. The rotating rod 43 is rotatably connected between the front and rear inner walls of the tea box 1 through a bearing. Multiple striking rods 44 are fixedly connected axially at equal intervals on the outer wall of the rotating rod 43. At the position opposite to the striking rods 44, a baffle 42 is fixedly connected to the inner wall of the tea box 1. The baffle 42 cooperates with the rotating striking rods 44 to block the tea and break up the clumps of tea.
[0025] The driving structure of the dispersing mechanism 4 includes two symmetrically arranged movable rods 45. The movable rods 45 pass vertically through and slide on the edges of the gathering hopper 5 and the U-shaped baffle 6. The top of each movable rod 45 is fixedly connected to a rack 46. The outer walls of the front and rear ends of the rotating rod 43 are fixedly fitted with gears 47. The rack 46 and the corresponding gear 47 are meshed. The bottom of the movable rod 45 is fixedly connected to a contact plate 48. Below the contact plate 48, there is a telescopic rod 49 fixed to the inner wall of the tea box 1. The telescopic rod 49 pushes the contact plate 48 to move upward. The front and rear ends of the rotating shaft 31 on the left side are fixedly connected to two cams 410. The outer walls of the cams 410 are attached to the top surface of the contact plate 48.
[0026] Working principle: When the conveyor mechanism 3 is in operation, the left-side rotating shaft 31 drives the cam 410 to rotate. The cam 410 presses down against the contact plate 48, forcing the movable rod 45 and the top rack 46 to overcome the elastic force of the telescopic rod 49 and move downward in a straight line. The linear movement of the rack 46 drives the gear 47 and the rotating rod 43 to rotate. The rotational swing angle of the rotating rod 43... The following relationship must be satisfied: , In the formula, denoted as _h_, which is the swing angle of the rotating rod 43 and the striking rod 44, in radians; _h_ is the linear displacement stroke of the cam 410 pressing down on the contact plate 48; and _r_ is the pitch circle radius of the gear 47.
[0027] The striking rod 44 strikes the tea clumps that slide down from the feed ramp 41. When the short radius end of the cam 410 rotates to the bottom, the telescopic rod 49 pushes the contact plate 48 and the movable rod 45 to return to their original position. The rack 46 moves up and drives the rotating rod 43 to rotate in the opposite direction. The striking rod 44 rises up, and the rotating shaft 31 rotates continuously, causing the rotating rod 43 to swing back and forth, striking the falling backflowing tea leaves. Combined with the blocking effect of the baffle 42, the tea clumps are broken up. Example
[0028] Please see Figure 1-8 Based on the above embodiment 2, the tea box 1 is provided with a toggle mechanism 9 located above the conveying mechanism 3. The toggle mechanism 9 includes a slide rod 96 that is horizontally and slidably connected to the bottom slide cavity of the gathering hopper 5. Multiple vertically downward toggle rods 97 are fixedly connected at equal intervals to the bottom outer wall of the slide rod 96. The bottom end of the toggle rod 97 extends downward to the top of the conveyor belt 35 and maintains a gap with the surface of the conveyor belt 35.
[0029] One of the rotating shafts 31 has an internal mounting cavity. Two fixing sleeves 91 are symmetrically arranged in the mounting cavity. Connecting rods 92 are symmetrically fixed to the left and right sides of the outer wall of the fixing sleeves 91. The connecting rods 92 pass through the annular clearance groove on the tube wall of the rotating shaft 31 and fix the other end of the connecting rods 92 to the inner wall of the tea box 1. The fixing sleeves 91 remain stationary inside the rotating shaft 31. A reciprocating screw 93 is slidably connected to the inner wall of the fixing sleeves 91. A bidirectional spiral groove with the ends connected is opened on the outer cylindrical surface of the reciprocating screw 93. Synchronizing rods 95 are fixedly connected to the front and rear ends of the sliding rod 96. The end of the synchronizing rod 95 away from the sliding rod 96 is connected to the reciprocating screw 93. A ball slider 94 is fixedly connected to the inner wall of the mounting cavity of the rotating shaft 31. The ball slider 94 is fitted into the bidirectional spiral groove on the outer wall of the reciprocating screw 93.
[0030] Working principle: When the rotating shaft 31 rotates continuously, the ball block 94 fixed on the inner wall of the rotating shaft 31 rotates around the reciprocating screw 93 in a circular motion. The reciprocating screw 93 is restricted by the fixed sleeve 91 and the synchronizing rod 95 and cannot rotate on its own. The rotating ball block 94 applies a thrust along the spiral groove on the surface of the reciprocating screw 93, causing the reciprocating screw 93 to move back and forth linearly within the fixed sleeve 91. The linear speed v of the reciprocating screw 93 and the rotational speed n of the rotating shaft 31 satisfy the following relationship: , In the formula, v is the reciprocating linear speed of the reciprocating lead screw 93 and slide bar 96; n is the rotational speed of the rotating shaft 31; and L is the lead of the bidirectional helical groove on the outer wall of the reciprocating lead screw 93.
[0031] The translation of the reciprocating screw 93 drives the slide bar 96 and the lever 97 to move back and forth horizontally above the conveyor belt 35 via the synchronizing rod 95. The laterally moving lever 97 moves the pile of tea leaves falling from the gathering bucket 5 back and forth, so that the tea leaves form a uniform material layer on the conveyor belt 35 before entering the fermentation box 2. The uniform material layer improves the consistency of heat radiation penetration of the lamp strip 8 and ensures the uniformity of the fermentation quality of black tea.
[0032] This invention provides a temperature-controlled lamp for uniform fermentation of black tea. Many methods and approaches exist for implementing this technical solution; the above are merely preferred embodiments. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
