Automatic spreading type fermentation device for tea processing

Abstract

This invention relates to the field of tea processing technology and discloses an automatic spreading fermentation device for tea processing, including a base. A fermentation box is fixedly connected to the top of the base. A fermentation frame is set inside the fermentation box, and several round holes are opened inside the fermentation frame. By driving a sliding sleeve to move laterally back and forth along the sliding rod through an electric push rod, a turning rod is driven to move a long distance within the fermentation frame, improving the uniformity of tea turning. During the translation process, the gears at both ends of the rotating rod mesh with the rack. When it moves to the rack sections at the left and right ends of the box, the gears drive the rotating rod and the turning rod to rotate automatically, changing the material-pushing angle of the turning rod from translational pushing to rotational turning and throwing. This forces the bottom layer of tea leaves to rise and the surface layer of tea leaves to sink, achieving deep three-dimensional replacement, significantly improving the uniformity of fermentation, and completely solving the problems of dead material accumulation at the end, local over-fermentation, or mold growth that exist in traditional scraper-type turning. This ensures that every piece of tea leaves participates in the cyclic turning process.

Description

Technical Field

[0001] This invention relates to the field of tea processing technology, specifically to an automatic spreading fermentation device for tea processing. Background Technology

[0002] The processing of tea typically includes key steps such as picking, withering, fixation, rolling, fermentation, and drying. Among these, fermentation specifically refers to the transformation of substances within the tea leaves through enzymatic oxidation under suitable temperature and humidity. The core function of fermentation is to shape the color, aroma, and flavor characteristics of tea, reduce its irritation, and increase the content of antioxidants to enhance its health benefits. Furthermore, the precise control of its degree directly determines the quality and flavor of the tea.

[0003] For example, CN223759148U discloses a fermentation device for tea processing, which solves the problem that it is inconvenient to turn the tea leaves, which may result in low humidification uniformity. The device includes a housing, inside which a placement plate for laying and holding tea leaves is fixedly installed. Above the placement plate is a guide moving component for turning the tea leaves and spraying water for humidification. The guide moving component includes a distribution pipe positioned above the placement plate, a connecting pipe installed on one side of the distribution pipe, and a turning bottom pipe evenly installed at the bottom end of the distribution pipe. The bottom end of the turning bottom pipe is inserted into the tea leaves, and spray holes are evenly distributed on the outer side of the bottom end of the turning bottom pipe. One end of the connecting pipe is connected to a water inlet humidification component for movement drive and water inlet. In operation, the turning bottom pipe moves along the length of the placement plate, facilitating humidification of the tea leaves at different positions.

[0004] During tea fermentation, the tea leaves need to be turned over. However, dead material often remains at the four corners of the fermentation box and at the end of the scraper's movement. This material does not participate in the circulating turning and piling, leading to over-fermentation or even mold growth in this part. When mixed into the finished product, this results in an impure flavor for the entire batch, affecting the quality of the tea. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automatic spreading fermentation device for 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 automatic spreading-type tea processing fermentation device, including a base, a fermentation box fixedly connected to the top of the base, a fermentation frame provided inside the fermentation box, a plurality of round holes opened inside the fermentation frame, a uniform stirring mechanism provided inside the fermentation box, the uniform stirring mechanism including a slide rod, the slide rod fixedly connected to the inner wall of the fermentation box, a sliding sleeve movably fitted on the outer wall of the slide rod, a vertical plate fixedly connected to the top of the sliding sleeve, and an electric push rod fixedly connected between the vertical plate and the inner wall of the fermentation box. A telescopic rod is fixedly connected to the bottom of the sliding sleeve, and a connecting frame is fixedly connected to the bottom of the telescopic rod. A first spring is movably fitted onto the outer wall of the telescopic rod. A connecting hole is opened in the inner wall of the fermentation frame, and a slider is slidably connected inside the connecting hole. A rotating rod is rotatably connected inside the connecting frame and the slider, extending to its front and rear sides. A flipping rod is fixedly connected to the outer wall of the rotating rod. The flipping rod is an elastic rod. When the electric push rod is activated, it drives the vertical plate to move the sliding sleeve laterally along the sliding rod. The sliding sleeve, through the telescopic rod at the bottom and the first spring, drives the connecting frame to move synchronously. The translational movement of the connecting frame drives the slider to slide along the connecting hole in the inner wall of the fermentation frame, causing the rotating rod and flipping rod connected to it to move laterally as a whole. During the translational movement, the flipping rod continuously pushes and pulls the tea layer, causing a macroscopic positional exchange of the tea leaves.

[0007] Preferably, a gear is fixedly connected to the outer wall of the rotating rod, and a rack is fixedly connected to the front of the fermentation frame. The rack has a smooth end in the middle and rack segments at both ends. When the rotating rod moves with the connecting frame to the left and right ends of the fermentation frame, the gears fixed at both ends of the rotating rod mesh with the rack segments, driving the rotating rod and the turning rod to rotate automatically. The turning rod's operation mode changes from translational pushing to rotational turning, forcibly lifting the bottom layer of tea leaves and sinking the surface layer, achieving deep three-dimensional displacement of materials in the vertical direction and avoiding dead corners in the turning process. When the gear moves to the smooth end in the middle of the rack, the rotation stops, and the turning rod returns to the translational pushing state to reduce unnecessary disturbance. The turning rod is made of elastic material and is connected to the first spring via a telescopic rod, which can automatically buffer and avoid resistance, preventing hard squeezing and damage to the tea leaves.

[0008] Preferably, the fermentation tank is provided with a shaking mechanism, which includes a chute. The chute is formed on the inner wall of the fermentation tank, and a moving block is slidably connected inside the chute. A second spring is fixedly connected between the moving block and the chute.

[0009] Preferably, an abutment rod is fixedly connected to the front of the connecting frame, and an abutment plate is fixedly connected to the inner wall of the fermentation box. The abutment plate is inverted conical in shape and is respectively arranged on the left and right sides inside the fermentation box. The abutment rod contacts the abutment plate.

[0010] Preferably, a fixed plate is fixedly connected inside the fermentation box, and a poking rod is fixedly connected to the top of the fixed plate. The poking rod is located inside a circular hole inside the fermentation frame, with its top end flush with the top end of the circular hole. During the lateral movement of the connecting frame, the abutment rod fixed to its front will periodically contact the inverted conical abutment plates on the left and right sides of the inner wall of the fermentation box. When the abutment rod moves along the inclined surface of the abutment plate and passes its tip, the abutment rod is forced down, causing the connecting frame, slider, and the entire fermentation frame linked to it to overcome the supporting force of the second spring and move downward along the slide groove. When the abutment rod disengages from the tip of the abutment plate, the fermentation frame quickly returns to its original position under the rebound force of the second spring, thus producing a significant up-and-down shaking motion. This shaking motion causes the tea pile inside the fermentation frame to loosen as a whole, and the tea particles to rearrange their positions. At the same time, when the fermentation frame moves downward and resets, the piercing rod fixed on the fixed plate is pushed out from the round hole at the bottom of the frame due to the downward movement of the fermentation frame. Its tip pierces into and pries the bottom layer of tea leaves that are close to the bottom of the frame, forcibly loosening the bottom layer of material that is not breathable due to gravity compaction, and transmitting the disturbance to the upper layer.

[0011] Preferably, the fermentation box is provided with a combing mechanism inside, the combing mechanism includes a horizontal plate, the horizontal plate is fixedly connected to the inner wall of the fermentation box, and the horizontal plate has corrugated holes inside.

[0012] Preferably, the inner wall of the connecting frame is provided with a sliding hole, a connecting block is slidably connected inside the sliding hole, a connecting plate is fixedly connected to the left and right sides of the connecting block respectively, a fixing rod is fixedly connected to the top of the two connecting plates, and the corrugated hole is sleeved on the outer wall of the fixing rod.

[0013] Preferably, a combing rod is fixedly connected to the bottom of the two connecting plates, and a third spring is sleeved on the outer wall of the two combing rods. There are four components: connecting blocks, connecting plates, combing rods, and third springs, arranged in two groups on the front and rear sides of the fermentation frame. The two groups of connecting blocks are fixedly connected by connecting rods. While the connecting frame moves laterally, the connecting blocks in the sliding holes on its inner wall are constrained by the wavy holes on the horizontal plate through the fixed rod at the top. When the connecting frame moves, the fixed rod is forced to move along the curved path of the wavy holes, thereby driving the connecting blocks to slide laterally back and forth within the sliding holes. The lateral movement of the connecting blocks is synchronously transmitted to the combing rods at the bottom through the connecting plates, causing the two groups of combing rods to swing laterally along the wavy path within the fermentation frame. The swinging motion of the combing rods continuously combs the surface of the tea layer, smoothing out local peaks or depressions formed after the turning rods have turned the tea leaves, and pushing the tea leaves at both ends back towards the central area, ensuring that the tea leaves maintain a preset uniform thickness within the fermentation frame.

[0014] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This automatic spreading-type tea processing fermentation device uses an electric push rod to drive a sliding sleeve to reciprocate laterally along the slide rod, causing a turning rod to move a long distance within the fermentation frame. This improves the uniformity of tea leaf turning. During the translation process, the gears at both ends of the rotating rod mesh with the rack. When the rotating rod reaches the rack sections at the left and right ends of the box, the gears drive the rotating rod and the turning rod to rotate automatically, changing the material-pushing angle of the turning rod from translation to rotation and turning. This forces the bottom layer of tea leaves to rise and the surface layer to sink, achieving deep three-dimensional replacement and significantly improving the uniformity of fermentation. This completely solves the problems of dead material accumulation at the end, local over-fermentation, or mold growth that exist in traditional scraper-type turning, ensuring that every piece of tea leaf participates in the cyclic turning process.

[0015] 2. This automatic spreading fermentation device for tea processing, by setting a shaking mechanism, enables the fermentation frame to overcome the supporting force of the second spring and generate significant up-and-down shaking along the chute. This causes slight positional misalignment and rearrangement of the tea leaves between the surface and bottom layers, and between the center and the edges, compensating for the insufficient vertical displacement capability of the horizontal stirring rod. This significantly improves the randomness and uniformity of the tea leaves participating in the cyclic turning within the fermentation frame. Furthermore, when the fermentation frame completes one shaking under the action of the contact plate and falls with the rebound of the second spring, the stick, which was originally flush with the top of the round hole on the bottom surface of the fermentation frame, will be passively pushed out of the round hole due to the downward movement of the fermentation frame. The tip of the pushed-out stick will directly pierce and pry the bottom layer of tea leaves tightly attached to the bottom of the frame, forcibly loosening the layer of material that is most prone to poor air permeability due to gravity compaction. This further eliminates the blind spots in the turning process, ensuring a more precise uniformity of the turning of the entire frame of tea leaves from top to bottom.

[0016] 3. This automatic spreading-type tea processing fermentation device, when the connecting frame moves horizontally, is driven by the trajectory constraint of the fixed rod and the wave holes on the horizontal plate to drive the front and rear combing rods to generate lateral reciprocating swing along the wave path within the fermentation frame. This action is like a multi-toothed rake continuously combing the surface of the tea layer, which can quickly scrape off the local peaks or depressions formed after the turning rods turn and toss, so that the tea leaves always maintain a preset uniform thickness within the fermentation frame, eliminating the difference in fermentation rate caused by uneven thickness.

[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 1-8One embodiment of the present invention is: an automatic spreading type fermentation device for tea processing, including a base 1, a fermentation box 2 fixedly connected to the top of the base 1, a fermentation frame 3 provided inside the fermentation box 2, a plurality of round holes opened inside the fermentation frame 3, a uniform stirring mechanism 4 provided inside the fermentation box 2, the uniform stirring mechanism 4 including a slide rod 411, the slide rod 411 fixedly connected to the inner wall of the fermentation box 2, a sliding sleeve 412 movably fitted on the outer wall of the slide rod 411, a vertical plate 413 fixedly connected to the top of the sliding sleeve 412, an electric push rod 414 fixedly connected between the vertical plate 413 and the inner wall of the fermentation box 2, and a telescopic rod 415 fixedly connected to the bottom of the sliding sleeve 412. A connecting frame 417 is fixedly connected to the bottom of the telescopic rod 415. A first spring 416 is movably sleeved on the outer wall of the telescopic rod 415. A connecting hole is opened on the inner wall of the fermentation frame 3. A slider 418 is slidably connected inside the connecting hole. A rotating rod 419 is rotatably connected inside the connecting frame 417 and the slider 418 and extends to its front and rear sides. A flipping rod 420 is fixedly connected to the outer wall of the rotating rod 419. The flipping rod 420 is an elastic rod. When the electric push rod 414 is activated, the electric push rod 414 drives the vertical plate 413 to move the sliding sleeve 412 laterally along the sliding rod 411. The sliding sleeve 412 drives the connecting frame 417 to move synchronously through the telescopic rod 415 at the bottom and the first spring 416. The translational movement of the connecting frame 417 drives the slider 418 to slide along the connecting hole on the inner wall of the fermentation frame 3, thereby causing the rotating rod 419 and the flipping rod 420 connected to it to move laterally as a whole. During the translation process, the flipping rod 420 continuously pushes and pulls the tea layer, causing a macroscopic positional exchange of the tea leaves. The outer wall of the rotating rod 419 is fixedly connected to a gear 421, and the front of the fermentation frame 3 is fixedly connected to a rack 422. The middle of the rack 422 is a smooth end, and the two ends are rack segments. When the rotating rod 419 moves with the connecting frame 417 to the left and right ends of the fermentation frame 3, the gear 421 fixed at both ends of the rotating rod 419 and the rack segments of the rack 422 enter a meshing state, driving the rotating rod 419 and the flipping rod 420 to rotate automatically. The working mode of the flipping rod 420 changes from translational pushing to rotational flipping, forcibly lifting the bottom layer of tea leaves and sinking the surface layer of tea leaves, realizing a deep three-dimensional replacement of materials in the vertical direction, avoiding the formation of flipping dead corners. When the gear 421 moves to the middle smooth end of the rack 422, the rotation stops, and the flipping rod 420 returns to the translational pushing state to reduce ineffective disturbance. The flipping rod 420 is made of elastic material and is floatingly connected to the first spring 416 through the telescopic rod 415. It can automatically buffer and avoid resistance when it encounters resistance, thus preventing hard squeezing and damage to the tea leaves.

[0021] Working principle: When the electric push rod 414 is activated, it drives the vertical plate 413, causing the sliding sleeve 412 to reciprocate laterally along the sliding rod 411. Simultaneously, the sliding sleeve 412, through the telescopic rod 415 at the bottom and the first spring 416, drives the connecting frame 417 to move synchronously. The translational movement of the connecting frame 417 drives the slider 418 to slide along the connecting hole on the inner wall of the fermentation frame 3, causing the rotating rod 419 and the flipping rod 420 connected to it to move laterally as a whole. During the translational movement, the flipping rod 420 continuously pushes and pulls the tea layer, causing a macroscopic positional exchange of the tea leaves. When the rotating rod 419 moves with the connecting frame 417 to the left and right ends of the fermentation frame 3, the gears 421 fixed at both ends of the rotating rod 419 mesh with the rack section of the rack 422, driving the rotating rod 419 and the flipping rod 420 to rotate automatically. The working mode of the flipping rod 420 changes from translational pushing to rotational flipping, forcibly lifting the bottom layer of tea leaves and sinking the surface layer of tea leaves, realizing deep three-dimensional displacement of materials in the vertical direction, avoiding the formation of flipping dead angles. When the gear 421 moves to the smooth end in the middle of the rack 422, the rotation stops, and the flipping rod 420 returns to the translational pushing state to reduce unnecessary disturbance. The flipping rod 420 is made of elastic rod material and is floatingly connected to the first spring 416 through the telescopic rod 415, which can automatically buffer and avoid resistance when encountering resistance, avoiding hard squeezing and damage to the tea leaves.

[0022] Please see Figure 1-8Based on the above embodiments, in another embodiment of the present invention, a shaking mechanism 5 is provided inside the fermentation box 2. The shaking mechanism 5 includes a slide groove 515, which is formed on the inner wall of the fermentation box 2. A moving block 516 is slidably connected inside the slide groove 515. A second spring 517 is fixedly connected between the moving block 516 and the slide groove 515. An abutment rod 514 is fixedly connected to the front of the connecting frame 417. An abutment plate 513 is fixedly connected to the inner wall of the fermentation box 2. The abutment plate 513 is inverted conical in shape. 513 are respectively set on the left and right sides of the inside of the fermentation box 2. The abutment rod 514 contacts the abutment plate 513. A fixed plate 511 is fixedly connected inside the fermentation box 2. A poking rod 512 is fixedly connected to the top of the fixed plate 511. The poking rod 512 is set inside the round hole inside the fermentation frame 3. The top of the poking rod 512 is flush with the top of the round hole. During the lateral translation of the connecting frame 417, the abutment rod 514 fixed on its front will periodically contact the inverted conical abutment plates 513 on the left and right sides of the inner wall of the fermentation box 2. When the abutment rod 514 moves along the inclined surface of the abutment plate 513 and passes its tip, the abutment rod 514 is forced down, which drives the connecting frame 417, the slider 418 and the entire fermentation frame 3 to overcome the supporting force of the second spring 517 and move downward along the slide groove 515. After the contact rod 514 disengages from the tip of the contact plate 513, the fermentation frame 3 quickly returns to its original position under the rebound force of the second spring 517, resulting in a significant up-and-down shaking motion. This shaking motion causes the tea pile inside the fermentation frame 3 to loosen as a whole, and the tea leaves are rearranged. At the same time, when the fermentation frame 3 moves downward and returns to its original position, the poking rod 512, fixed on the fixing plate 511, is pushed out from the round hole at the bottom of the frame due to the downward movement of the fermentation frame 3. Its tip pierces and pries the bottom layer of tea leaves that are tightly attached to the bottom of the frame, forcibly loosening the bottom layer of material that is poorly aerated due to gravity compaction, and transmitting the disturbance to the upper layers.

[0023] Working principle: During the lateral translation of the connecting frame 417, the abutment rod 514 fixed on its front side periodically contacts the inverted conical abutment plates 513 on the left and right sides of the inner wall of the fermentation box 2. When the abutment rod 514 moves along the inclined surface of the abutment plate 513 and passes its tip, the abutment rod 514 is forced down, causing the connecting frame 417, the slider 418, and the entire fermentation frame 3 to overcome the supporting force of the second spring 517 and move downward along the slide groove 515. When the abutment rod 514 disengages from the tip of the abutment plate 513, the fermentation frame 3 quickly returns to its original position under the rebound force of the second spring 517, thus producing a significant up-and-down shaking motion. This shaking motion causes the tea pile inside the fermentation frame 3 to loosen as a whole, and the tea particles are rearranged. At the same time, when the fermentation frame 3 moves downward and resets, the piercing rod 512 fixed on the fixing plate 511 is pushed out from the round hole at the bottom of the frame due to the downward movement of the fermentation frame 3. Its tip pierces into and pries the bottom tea leaves that are close to the bottom of the frame, forcibly loosening the bottom material layer that is not breathable due to gravity compaction, and transmitting the disturbance to the upper layer.

[0024] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, a combing mechanism 6 is provided inside the fermentation box 2. The combing mechanism 6 includes a horizontal plate 611, which is fixedly connected to the inner wall of the fermentation box 2. The horizontal plate 611 has a corrugated hole 612 inside. The inner wall of the connecting frame 417 has a sliding hole 613. A connecting block 614 is slidably connected inside the sliding hole 613. A connecting plate 615 is fixedly connected to the left and right sides of the connecting block 614, respectively. A fixing rod 616 is fixedly connected to the top of the two connecting plates 615. The corrugated hole 612 is sleeved on the fixing rod 616. On the outer wall, combing rods 617 are fixedly connected to the bottom of two connecting plates 615. A third spring 618 is fitted onto the outer wall of each combing rod 617. There are four components: connecting block 614, connecting plate 615, combing rod 617, and third spring 618, arranged in two groups on the front and rear sides of the fermentation frame 3. The two groups of connecting blocks 614 are fixedly connected by connecting rods. While the connecting frame 417 moves laterally, the connecting blocks 614 in the sliding holes 613 on its inner wall are constrained by the fixed rod 616 at the top and the wave-shaped holes 612 on the horizontal plate 611. When the connecting frame 417 moves, the fixed rod 616 is forced to move along the curved path of the wave-shaped holes 612, thereby driving the connecting blocks 614 to slide laterally back and forth within the sliding holes 613. The lateral movement of the connecting blocks 614 is synchronously transmitted to the combing rods 617 at the bottom through the connecting plate 615, causing the two groups of combing rods 617 to swing laterally along the wave-shaped path within the fermentation frame 3. The oscillating motion of the combing rod 617 can continuously comb the surface of the tea layer, scrape off the local peaks or depressions formed after the turning rod 420 turns and throws, and push the tea leaves that have moved to both ends back to the central area to disperse them, so that the tea leaves always maintain a preset uniform layer thickness in the fermentation frame 3.

[0025] Working principle: While the connecting frame 417 moves laterally, the connecting block 614 in the sliding hole 613 on its inner wall forms a trajectory constraint with the wave-shaped hole 612 on the horizontal plate 611 through the fixed rod 616 at the top. When the connecting frame 417 moves, the fixed rod 616 is forced to move along the curved path of the wave-shaped hole 612, thereby driving the connecting block 614 to slide laterally back and forth in the sliding hole 613. The lateral movement of the connecting block 614 is synchronously transmitted to the combing rod 617 at the bottom through the connecting plate 615, so that the two sets of combing rods 617 oscillate laterally along the wave-shaped path in the fermentation frame 3. The oscillating action of the combing rod 617 can continuously comb the surface of the tea layer, scrape off the local peaks or depressions formed after the turning rod 420 turns and throws, and push the tea leaves that have moved to both ends back to the central area to disperse them, so that the tea leaves always maintain a preset uniform layer thickness in the fermentation frame 3.
