Description

Technical Field

[0001] The invention relates to the technical field of fermentation devices, in particular to a vertical fermentation device for tea fermentation. Background Art

[0002] Tea fermentation is a key link in the tea making process. Its purpose is to change the composition and properties of tea through microorganisms, enzymes and oxidation, thereby forming different flavors, colors and quality characteristics. The vertical fermentation device for tea fermentation is a device used in the tea fermentation process. Through the vertical structure design, it provides a suitable environment for tea fermentation, which can effectively improve the fermentation efficiency and tea quality.

[0003] In the existing vertical fermentation device for tea fermentation, during the fermentation process of oolong tea, the essence of oolong tea fermentation is the oxidative polymerization process of tea polyphenols under the action of polyphenol oxidase, which requires sufficient oxygen participation. If the tea leaves are not turned over, the oxygen concentration O2≈18% on the surface of the tea pile is significantly different from O2<5% in the center, which can easily lead to excessive oxidation of the surface tea leaves, forming "burned edges" and a "sour and rancid taste" in the tea soup. After the tea leaves are properly turned over during the fermentation process, the oxygen permeability will be increased to the entire layer of the tea leaves, and the deviation of the polyphenol oxidation rate will be reduced from >20% to <5%, thereby improving the quality of the tea leaves. However, in order to facilitate the turning of the tea leaves during the fermentation of oolong tea, the fermentation device often uses mechanical turning to turn the tea leaves. During the mechanical stirring process, when the propeller and the flap turn the tea leaves, the blades are cut by the edge of the stirring paddle, and the breakage rate will reach 10% to 15%, thereby reducing the quality of the leaves.

[0004] Therefore, we propose a vertical fermentation device for tea fermentation in order to solve the problems raised above. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In order to achieve comprehensive breathing of the tea leaves in the fermentation box body, thereby making the oxidation reaction of the tea leaves more uniform, the leaves in the fermentation basket located above are slowly poured downward into the fermentation basket located below. During the pouring process, each piece of tea can fully contact with the air, and thus each piece of tea has sufficient oxygen to participate in the oxidation process. Moreover, since the tea leaves are poured downward slowly, the tea leaves will not be subjected to mechanical friction during the turning process, thereby reducing the breakage rate of the tea leaves during the turning process, solving the problem that most fermentation devices in the prior art use mechanical stirring to turn the tea leaves, which easily breaks the tea leaves and reduces the quality of the leaves.

[0018] 2. When the leaves fall into the fermentation basket below, in order to make the leaves evenly spread in the fermentation basket below, before the leaves fall, the fermentation basket below is slowly moved forward along the parallel rods, thereby pushing the fermentation basket below to move along the two parallel rods toward the protective door position of the fermentation box body. As the fermentation basket below moves slowly, the leaves that fall from the upper fermentation basket are evenly spread inside the fermentation basket below, preventing the accumulation of leaves from affecting fermentation.

[0019] 3. When the leaves in the upper fermentation basket are spread downwards, the two compression rods are rotated 180° until the fermentation basket carrying the leaves rotates to the upper position. Since the two fermentation baskets are rotatably connected to the corresponding movable connecting parts and the I-shaped connecting sleeves, and are affected by the gravity of the counterweight blocks themselves, the two fermentation baskets maintain a stable state with the front facing upward during the rotation. Since the two I-shaped connecting sleeves are limited by the rotating rods, the fermentation baskets will not slide along the parallel rods during the rotation. By rotating the fermentation basket carrying the leaves upward, it is convenient to pour and turn the tea leaves again, which prepares for further promoting the uniform oxidation reaction of the leaves.

The stepping motor 308 is started to drive the first electromagnet 316 to rotate, thereby driving the corresponding fermentation basket 306 to rotate and pouring the tea leaves downward. The rotating component 3 also includes a driving motor 302. The output end of the driving motor 302 is fixedly connected to the transmission shaft 303. The outer surface of the transmission shaft 303 is fixedly sleeved with anti-compression rods 301 near both ends. The outer surfaces of the two anti-compression rods 301 are fixedly installed with parallel rods 304.

[0036] In this embodiment, when oolong tea needs to be fermented, the pre-treated tea leaves are first placed inside the fermentation basket 306 located at the top, and then the fermentation box body 1 can be closed. Then, the temperature and air humidity inside the fermentation box body 1 are controlled by the controller 2 to provide a stable oxygen supply. During the aerobic respiration of the tea leaves, in order to achieve comprehensive respiration of the tea leaves and thus make the oxidation reaction of the tea leaves more uniform, the controller 2 can first electrically connect the first electromagnet 316 located at the top to the external power supply to generate a magnetic field, and at the same time, turn off the power supply of the corresponding second electromagnet 317 so that it no longer generates a magnetic field on the multiple rotating tubes 313. The plurality of rotating tubes 313 are made of iron alloy materials, and the plurality of rotating tubes 313 rotate respectively in the direction of the first electromagnet 316 under the elasticity of the corresponding coil spring 312. After the first electromagnet 316 is energized, an adsorption force is generated on the plurality of iron blocks 315, so that the plurality of iron blocks 315 move toward the outer surface of the first electromagnet 316 respectively until the plurality of iron blocks 315 are tightly adsorbed on the outer surface of the first electromagnet 316, thereby causing the plurality of first springs 314 corresponding thereto to be pulled and stretched, thereby indirectly realizing the connection between the plurality of rotating tubes 313 and the fermentation basket 306. The state after connection is shown in the figure. Figure 4 As shown, the stepper motor 308 can be started at this time to drive the rotating rod 310 to rotate, and then drive the multiple rotating tubes 313 to rotate, thereby driving the corresponding first electromagnet 316 to rotate, and then driving the corresponding fermentation basket 306 to rotate downward, and slowly pouring the tea leaves into the interior of the fermentation basket 306 located below. During the pouring process, each piece of tea can fully contact with the air, and thus each piece of tea has sufficient oxygen to participate in the oxidation process. Moreover, since the tea leaves are slowly poured downward, the tea leaves will not be subjected to mechanical friction during the turning process, thereby reducing the breakage rate of the tea leaves during the turning process, and solving the problem that most fermentation devices in the prior art use mechanical stirring to turn the tea leaves, which easily breaks the tea leaves and reduces the quality of the leaves.

[0037] like Figures 1-12As shown, the outer surfaces of the two fermentation baskets 306 are provided with a connecting assembly 4, and the two connecting assemblies 4 include mounting blocks 401. The outer surfaces of the two mounting blocks 401 are fixedly connected to the outer surfaces of the two fermentation baskets 306 respectively. The interiors of the two mounting blocks 401 are movably embedded with T-shaped columns 403, and one end of the two T-shaped columns 403 is fixedly installed with a third electromagnet 402. The opposite inner walls of the two mounting blocks 401 are provided with multi-stage electric telescopic rods 404, and one end of the four multi-stage electric telescopic rods 404 is fixed. A moving block 405 is installed, and each adjacent two moving blocks 405 form a group. The outer surface of each group of moving blocks 405 is slidably connected to the inner wall of the two mounting blocks 401. The outer surface of the four moving blocks 405 is provided with a hydraulic rod 406. One end of each of the four hydraulic rods 406 is fixedly installed with a pressure plate 407. One end of each of the four pressure plates 407 is fixed with a limit rod 408. The extension component 5 includes a servo motor 501. The outer surface of the servo motor 501 is fixed to the inner wall of the fermentation box body 1 by screws. The output end of the servo motor 501 is fixedly connected to a threaded rod 502, and the outer surface of the threaded rod 502 is threadedly connected to a threaded sleeve 503. The outer surface of the threaded sleeve 503 is provided with two slide grooves 504. A driving sleeve 505 is slidably connected between the inner walls of the two slide grooves 504. The inner wall of the driving sleeve 505 slides with the outer surface of the threaded sleeve 503. One end of the threaded sleeve 503 is provided with a connecting hole 506. The interior of the connecting hole 506 is rotatably connected to a T-shaped friction block 507. One end of the T-shaped friction block 507 is provided with a connecting hole 506. The end is movable through the outside of the threaded sleeve 503, and a screw rod 508 is fixed to one end of the T-shaped friction block 507. The outer surface of the screw rod 508 is threadedly connected to the inner wall of the driving sleeve 505. A telescopic column 509 is fixedly installed on one end of the screw rod 508. A second spring 510 is provided on the outer surface of the telescopic column 509. A connecting block 511 is fixed to one end of the telescopic column 509. One end of the second spring 510 is fixedly connected to one end of the screw rod 508, and the other end of the second spring 510 is fixedly connected to the outer surface of the connecting block 511.

[0038] In this embodiment, after the blades fall into the fermentation basket 306 located below, in order to make the blades evenly spread in the fermentation basket 306 below, before the blades fall, the third electromagnet 402 corresponding to the fermentation basket 306 below is first electrically connected to the external power supply to generate a magnetic field, which generates an adsorption force on the connecting block 511, so that the connecting block 511 is inserted into the interior of the corresponding mounting block 401 and is tightly connected to the outer surface of the third electromagnet 402, so that the second spring 510 is pulled and extended, and then the two hydraulic rods 406 are activated to extend. The two multi-stage electric telescopic rods 404 are activated to extend, and the two moving blocks 405 are respectively moved toward the center position of the mounting block 401, thereby driving the two limiting rods 408 to move toward the inside of the driving sleeve 505, until the outer surfaces of the two limiting rods 408 are inserted into the inside of the driving sleeve 505. At this time, the positional relationship between the driving sleeve 505 and the limiting rods 408 is as follows: Figure 11 As shown, at this time, the two hydraulic rods 406 can be started again to shorten them, driving the two limiting rods 408 to move toward the mounting block 401, thereby causing the drive sleeve 505 to move along the direction of the two limiting rods 408, thereby causing the screw rod 508 to rotate, wherein, as shown in FIG. Figure 12 As shown, the screw rod 508 is connected to the inside of the connecting hole 506 through the T-shaped friction block 507, and the outer surface of the T-shaped friction block 507 and the inner wall of the connecting hole 506 are slightly bulged, and the bulge on the surface of the T-shaped friction block 507 is made of rubber material. Its purpose is to prevent the T-shaped friction block 507 from rotating freely without external force. The rotation of the screw rod 508 causes the T-shaped friction block 507 to rotate along the inside of the connecting hole 506. At this time, the rubber bulge on the surface of the T-shaped friction block 507 is squeezed by the bulge in the connecting hole 506 and deformed inwardly until the bulge is separated from the bulge in the connecting hole 506, thus realizing the rotation of the T-shaped friction block 507, and then realizing the rotation of the screw rod 508. The screw rod 508 drives the connecting block 511 to rotate, and then drives the third electromagnet 402 to rotate 90°, thereby rotating the T-shaped column 403, wherein, as shown in FIG. Figure 10As shown, the surface of the T-shaped column 403 also has multiple protrusions, the purpose of which is to increase the friction between the T-shaped column 403 and the inner wall of the mounting block 401 to prevent the T-shaped column 403 from rotating at will. When the connecting block 511 completes its rotation, the blades at the upper portion just tilt downward, and the servo motor 501 can be started to drive the threaded rod 502 to rotate. At this time, since the threaded sleeve 503 is limited by the driving sleeve 505, the threaded sleeve 503 is driven by the threaded rod 502 to move in the direction of the threaded sleeve 503, thereby pushing the connecting block 511 to move forward, and then pushing the mounting block 401 connected thereto to move forward, thereby pushing the fermentation basket 306 located below to move along the two parallel rods 304 toward the protective door position of the fermentation box body 1. As the fermentation basket 306 below moves slowly, the blades that fall from the upper fermentation basket 306 are evenly spread inside the fermentation basket 306 below, preventing the accumulation of blades from affecting fermentation.

A limit rod 408 is fixed on one end of each of the four pressure plates 407.

[0040] After the first electromagnet 316 is in the state of being rotated, the first electromagnet 316 is in the state of being rotated. After the two fermentation baskets 306 are separated, the driving motor 302 can be started to drive the transmission shaft 303 to rotate, thereby driving the two anti-compression rods 301 to rotate 180 degrees, thereby driving the two fermentation baskets 306 to rotate until the fermentation baskets 306 carrying the leaves rotate to the upper position. At this time, since the two fermentation baskets 306 are rotatably connected to the corresponding movable connecting parts 305 and the I-shaped connecting sleeves 309, and are affected by the gravity of the counterweight block 307 itself, the two fermentation baskets 306 maintain a stable state with the front facing upward during the rotation. Since the two I-shaped connecting sleeves 309 are both limited by the rotating rod 310, the fermentation basket 306 will not slide along the parallel rods 304 during the rotation. By rotating the fermentation basket 306 carrying the leaves to the upper side, it is convenient to pour and flip the tea leaves again, so as to prepare for further promoting the uniform oxidation reaction of the leaves.

[0041] The method of use and working principle of this device: when oolong tea needs to be fermented, first place the pre-treated tea leaves inside the fermentation basket 306 located at the top, and then the fermentation box body 1 can be closed, wherein the fermentation box body 1 maintains a constant temperature through a heating tube and a temperature control system, and is also equipped with a gradient temperature control function to simulate the temperature changes of natural fermentation and optimize the ratio of theaflavins to thearubigins. The temperature in the fermentation box body 1 is made uniform through a fan circulation system to avoid uneven fermentation of local tea leaves due to uneven temperature. The fermentation box body 1 increases the humidity in the box through a steam generator to prevent the evaporation of tea water too quickly, causing the leaves to dry out and harden, affecting the contact between enzymes and substrates, and accelerating oxidation reactions to avoid anaerobic fermentation. The fan forces air circulation, and then the controller 2 controls the temperature and air humidity inside the fermentation box body 1 and provides a stable oxygen supply. The tea leaves are aerobic in the process of aerobic respiration. During the process, the controller 2 is first used to electrically connect the first electromagnet 316 located above to the external power supply to generate a magnetic field, and at the same time, the power supply of the corresponding second electromagnet 317 is turned off so that it no longer generates an adsorption force on the multiple rotating tubes 313, wherein the multiple rotating tubes 313 are all made of iron alloy materials, and the multiple rotating tubes 313 rotate in the direction of the first electromagnet 316 under the elasticity of the corresponding coil springs 312. After the first electromagnet 316 is energized, it generates an adsorption force on the multiple iron blocks 315, so that the multiple iron blocks 315 move toward the outer surface of the first electromagnet 316 respectively until the multiple iron blocks 315 are tightly adsorbed on the outer surface of the first electromagnet 316, thereby causing the corresponding multiple first springs 314 to be pulled and stretched, indirectly completing the connection between the multiple rotating tubes 313 and the fermentation basket 306. The state after connection is shown in the figure. Figure 4As shown, the stepper motor 308 can be started at this time to drive the rotating rod 310 to rotate, and then drive the multiple rotating tubes 313 to rotate, thereby driving the corresponding first electromagnet 316 to rotate, thereby driving the corresponding fermentation basket 306 to rotate downward, and slowly pouring the tea leaves into the interior of the fermentation basket 306 located below. During the pouring process, each piece of tea can fully contact with the air, thereby ensuring that each piece of tea has sufficient oxygen to participate in the oxidation process, and because the tea leaves are slowly poured downward, the tea leaves will not be subjected to mechanical friction during the turning process. After the leaves fall into the interior of the fermentation basket 306 located below, in order to make the leaves evenly spread in the fermentation basket 306 below, before the leaves are poured, the third electromagnet 402 corresponding to the fermentation basket 306 below is first electrically connected to the external power supply to generate a magnetic field to the connecting block 5 11 generates an adsorption force, so that the connecting block 511 is inserted into the interior of the corresponding mounting block 401 and is tightly connected to the outer surface of the third electromagnet 402, so that the second spring 510 is pulled and stretched, and then the two hydraulic rods 406 are started to stretch, driving the two pressure-resistant plates 407 to move toward the outer surfaces of the corresponding driving sleeves 505 respectively, until the bar positions of the two limiting rods 408 move to the positions corresponding to the driving sleeves 505, and then the two multi-stage electric telescopic rods 404 are started to stretch respectively, driving the two moving blocks 405 to move toward the center position of the mounting block 401 respectively, and then driving the two limiting rods 408 to move toward the interior of the driving sleeve 505 respectively, until the outer surfaces of the two limiting rods 408 are inserted into the interior of the driving sleeve 505. At this time, the positional relationship between the driving sleeve 505 and the limiting rod 408 is as follows Figure 11 As shown, at this time, the two hydraulic rods 406 can be started again to shorten them, driving the two limiting rods 408 to move toward the mounting block 401, thereby causing the drive sleeve 505 to move along the direction of the two limiting rods 408, thereby causing the screw rod 508 to rotate, wherein, as shown in FIG. Figure 12 As shown, the screw rod 508 is connected to the inside of the connecting hole 506 through the T-shaped friction block 507, and the outer surface of the T-shaped friction block 507 and the inner wall of the connecting hole 506 are slightly bulged, and the bulge on the surface of the T-shaped friction block 507 is made of rubber material. The rotation of the screw rod 508 causes the T-shaped friction block 507 to rotate along the inside of the connecting hole 506. At this time, the rubber bulge on the surface of the T-shaped friction block 507 is squeezed by the bulge in the connecting hole 506 and deformed inward until the bulge is separated from the bulge in the connecting hole 506, thus realizing the rotation of the T-shaped friction block 507, and then realizing the rotation of the screw rod 508. The screw rod 508 drives the connecting block 511 to rotate, and then drives the third electromagnet 402 to rotate 90°, thereby rotating the T-shaped column 403, wherein, as shown in FIG. Figure 10As shown, the surface of the T-shaped column 403 also has multiple protrusions. When the connecting block 511 completes its rotation, the blades at the upper portion just tilt downward, and the servo motor 501 can be started to drive the threaded rod 502 to rotate. At this time, since the threaded sleeve 503 is limited by the driving sleeve 505, the threaded sleeve 503 moves in the direction of the principle threaded sleeve 503 under the driving action of the threaded rod 502, thereby pushing the connecting block 511 to move forward, and then pushing the mounting block 401 connected thereto to move forward, thereby pushing the fermentation basket 306 located below to move along the two parallel rods 304. The protective door of the fermentation box body 1 moves, and as the fermentation basket 306 below moves slowly, the leaves that fall from the upper fermentation basket 306 are evenly spread inside the fermentation basket 306 below. When the leaves in the upper fermentation basket 306 are spread downward, the servo motor 501 can be started in the reverse direction to drive the threaded rod 502 to rotate in the reverse direction, thereby driving the threaded sleeve 503 to move in the reverse direction until the fermentation basket 306 below is reset. Then, the two multi-stage electric telescopic rods 404 can be started in the reverse direction to shorten them, driving the two limit rods 408 to move out from the interior of the drive sleeve 505. Then the two hydraulic rods 406 are started again, driving the two limit rods 408 to reset, and the third electromagnet 402 is powered off, so that the connecting block 511 is reset, and then the first electromagnet 316 located above is disconnected from the external power supply so that it no longer generates a magnetic field. At this time, the multiple iron blocks 315 will be reset under the elastic action of the multiple first springs 314 and rotate upward under the elastic action of the multiple coil springs 312, so that the iron blocks 315 are separated from the first electromagnet 316. Then the drive motor 302 can be started to drive the transmission shaft 303 to rotate, thereby driving the two anti-compression rods 301 Rotate 180°, thereby driving the two fermentation baskets 306 to rotate until the fermentation basket 306 carrying the blades rotates to the upper position. At this time, since the two fermentation baskets 306 are rotatably connected to the corresponding movable connecting parts 305 and the I-shaped connecting sleeves 309, and are affected by the gravity of the counterweight block 307 itself, the two fermentation baskets 306 maintain a stable state with the front facing upward during the rotation process. Since the two I-shaped connecting sleeves 309 are both limited by the rotating rod 310, the fermentation basket 306 will not slide along the parallel rod 304 during the rotation process.
