Description

[0002] Tea is a common drink in people's lives, among which black tea is chosen by many people because of its strong taste. During the production and processing of black tea, fermentation is through enzymatic oxidation that the internal components of the tea leaves change to form substances such as theaflavins, thearubigins and theabrownins. These substances give black tea its unique red color, sweet taste and mellow taste.

[0003] In the fermentation process of black tea, pile fermentation or steam fermentation is usually used. Steam fermentation can keep the enzyme substances in the tea leaves active during the fermentation process and ensure that the tea leaves can maintain a certain humidity, which is conducive to the fermentation process. The tea leaves need to be in contact with oxygen during the fermentation process, which requires the tea leaves to be turned over. In the existing steam fermentation process, the turning of the tea leaves is often done manually by workers, and the thickness of the tea leaves after turning is uneven, which will cause inconsistent temperature and cause over-fermentation or incomplete fermentation, affecting the contact between oxygen and tea leaves and seriously affecting the quality of fermentation.

[0044] S2, high temperature fermentation: high temperature steam is introduced into the fermentation box 1 to form a high temperature and high humidity fermentation environment, so as to ferment the tea leaves sent into the fermentation box 1 in the above S1;

[0045] S3, turning the tea leaves: turning the tea leaves fermented for a period of time in S2 by placing the tray 2, to ensure that the tea leaves are evenly heated and in contact with oxygen, to prevent over-fermentation or incomplete fermentation;

[0046] The utility model also includes: a turning mechanism 3, which is used for turning the tea leaves on the surface of the placement tray 2, and the turning mechanism 3 is rotatably connected to the inside of the placement tray 2. The turning mechanism 3 includes two rollers 301 and a rotating belt 302. The two rollers 301 are symmetrically rotatably connected to the inside of the placement tray 2, and the rotating belt 302 is rotatably connected to the inside of the placement tray 2 through the two rollers 301. The tea leaves are placed on the top of the rotating belt 302. Both sides of the inner wall of the placement tray 2 are fixedly connected with guide slopes 7, and the two guide slopes 7 are respectively slidably connected to the two sides of the top of the rotating belt 302. A motor 8 is fixedly connected to one side of the fermentation box 1, and a rotating wheel 9 is symmetrically rotatably connected to the inside of the fermentation box 1. A connecting belt 10 is transmission-connected between the two rotating wheels 9, one side of one rotating wheel 9 is fixedly connected to the motor 8, and the surface of the other rotating wheel 9 is connected to a guide wheel 11 through a belt drive, and one side of one roller 301 is fixedly connected to a connecting pin 12, and the connecting pin 12 is arranged to penetrate one side of the placement tray 2, and the other end of the connecting pin 12 is plugged into the guide wheel 11.

[0047] The tea leaves are evenly spread on the top of the rotating belt 302, and the entire placement tray 2 is inserted into the fermentation box 1. At this time, the connecting pin 12 is plugged into the guide wheel 11, and steam is introduced into the fermentation box 1 for fermentation. After a period of fermentation, the rotating belt 302 is driven by the roller 301 to rotate, forcing the tea leaves to move toward one end of the placement tray 2, and the tea leaves are pushed up by the guide slope 7, thereby achieving the effect of fully turning the tea leaves.

[0048] The pushing mechanism 4 is used to flatten the turned tea leaves to prevent excessive accumulation. The pushing mechanism 4 is rotatably connected to the inside of the fermentation box 1. The pushing mechanism 4 includes a connecting ring 401, a connecting sleeve 402 and a push box 403. The connecting ring 401 is rotatably connected to one side of the inside of the fermentation box 1. One end of the connecting sleeve 402 is fixedly connected to the surface of the connecting belt 10. The inside of the connecting sleeve 402 is rotatably connected with a rotating shaft 13, and the rotating shaft 13 and the connecting sleeve 402 are penetrated. One end of the rotating shaft 13 close to the push box 403 is penetrated with the connecting ring 401, and the rotating shaft 13 is rotatably connected to the connecting ring 401. The push box 403 is slidably connected to the inside of the fermentation box 1 through the connecting ring 401, and one end of the rotating shaft 13 is rotatably connected to the inside of the push box 403. A tooth groove 24 is provided inside the connecting sleeve 402, and a ratchet 25 is fixedly sleeved on the surface of the rotating shaft 13 located inside the connecting sleeve 402, and the ratchet 25 is unidirectionally meshed with the tooth groove 24.

[0049] Among them, while the tea leaves are turned over, the connecting belt 10 drives the connecting ring 401 and the push box 403 to move through the rotating shaft 13. While the push box 403 slides above the placement plate 2, it pushes the turned-over tea leaves in the opposite direction of the rotation of the rotating belt 302. Since the height of the push box 403 remains unchanged, the uniformity of the tea leaf stacking thickness can be ensured during the process of pushing the tea leaves, excessive stacking can be prevented, and the overall consistency of fermentation can be ensured. In addition, the one-way meshing effect between the ratchet 25 and the tooth groove 24 can ensure that the direction of the push box 403 is consistent during the continuous sliding of the connecting ring 401 and the push box 403, and the push box 403 can be prevented from rotating on its own.

[0050] The scattering mechanism 5 is slidably connected to the inside of the pushing mechanism 4, and is used to scatter the tea leaves. The scattering mechanism 5 includes an intermediate tooth 501, two bevel teeth 502 and two connecting plates 503. The intermediate tooth 501 and the two bevel teeth 502 are all rotatably connected to the inside of the push box 403, and the two bevel teeth 502 are symmetrically meshed with the two sides of the intermediate tooth 501. One end of the rotating shaft 13 is fixedly connected to the intermediate tooth 501, and the two connecting plates 503 are slidably connected to the bottom of the push box 403 in opposite directions. A pull rod 14 is hinged on the top of the connecting plate 503, and the other ends of the two pull rods 14 are respectively meshed with the two bevel teeth 502. The inside of the push box 403 is slidably connected with a dial head 15 through gravity, and the dial head 15 and the connecting plate 503 are arranged through, and the inside of the fermentation box 1 is fixedly connected with a tooth plate 16, and the end of the rotating shaft 13 away from the push box 403 is fixedly connected with a gear 17, and the gear 17 is meshed with the tooth plate 16.

[0051] Among them, when the push box 403 moves above the placement plate 2, its bottom is no longer in contact with the inside of the fermentation box 1. At this time, through the effect of its own gravity, the dial head 15 slides downward along the connecting plate 503 and slides out of the bottom of the push box 403. In the process of the movement of the push box 403, the gear 17 and the tooth plate 16 produce a rotation effect due to the meshing, and the two bevel teeth 502 can be driven to rotate through the middle tooth 501, so that the two connecting plates 503 can be driven to slide back and forth alternately through the pull rod 14, and the tea pile can be dispersed by the dial head 15 to ensure that oxygen can be evenly in contact with the inside of the tea pile, further ensuring the fermentation effect.

[0052] The cleaning mechanism 6 is arranged at one side of the fermentation box 1. The cleaning mechanism 6 is used to clean the tea leaves adhered to the bottom of the push mechanism 4. The cleaning mechanism 6 includes a cleaning pad 601 and a blowing plate 602. The cleaning pad 601 is embedded in one side of the fermentation box 1, and the cleaning pad 601 is slidably connected to the bottom of the push box 403. The blowing plate 602 is slidably connected to the inside of the fermentation box 1, and the blowing plate 602 is slidably connected to the top of the cleaning pad 601. A steam box 18 is arranged on one side of the fermentation box 1. The side of the blowing plate 602 away from the cleaning pad 601 is connected to the steam through a conduit. The box 18 is connected, and a transmission tooth 19 is meshed on the top of the blowing plate 602. A connecting tooth 20 is fixedly connected to one side of the transmission tooth 19. A gear ring 21 is meshed on the surface of the connecting tooth 20. The gear ring 21 is rotatably connected to the inside of the fermentation box 1. A clamp 22 is slidably connected to the surface of the connecting ring 401. Top springs 23 are symmetrically fixedly connected on both sides of the clamp 22. The other end of the top spring 23 is fixedly connected to the inside of the connecting ring 401. The clamp 22 is clamped with the gear ring 21. A coil spring 26 is fixedly connected between the connecting tooth 20 and the transmission tooth 19, and the other end of the coil spring 26 is fixedly connected to the inside of the fermentation box 1.

[0053] Among them, after the push box 403 moves from one end of the placement tray 2 to the other end, its bottom will slide to the bottom of the cleaning pad 601, and at this time the dial head 15 will be retracted into the inside of the push box 403, the dial head 15 prevents the adhered tea leaves from being scraped and gathered at the bottom of the push box 403, and the tea leaves at the bottom of the push box 403 can be cleaned by the cleaning pad 601, and with the rotation of the connecting ring 401, the clamping head 22 will be clamped with one side of the gear ring 21 and drive the gear ring 21 to rotate, and the transmission gear 19 can be driven to rotate by the connecting tooth 20, thereby driving the blowing plate 602 to slide in the direction close to the placement tray 2, and the tea leaves gathered on the surface of the cleaning pad 601 are pushed and scraped to the inside of the placement tray 2, because the steam passes into the interior of the fermentation box 1 through the blowing plate 602, while the blowing plate 602 pushes and scrapes the cleaning pad 601, the sprayed steam cooperates with the blowing plate 602 to clean the cleaning pad 601, thereby further improving the cleaning effect.

[0054] The specific working principle and use method of the present invention are explained in detail below: When in use, the first step is to evenly spread the tea leaves on the top of the rotating belt 302, and insert the entire placement tray 2 into the fermentation box 1. At this time, the connecting pin 12 is plugged into the guide wheel 11, and steam is introduced into the fermentation box 1 for fermentation. After a period of fermentation, the rotating belt 302 is driven to rotate by the roller 301, forcing the tea leaves to move toward one end of the placement tray 2, and the tea leaves are pushed up by the guide slope 7. The connecting belt 10 drives the connecting ring 401 and the push box 403 to move through the rotating shaft 13. While the push box 403 slides above the placement tray 2, it pushes the turned-up tea leaves in the opposite direction of the rotation of the rotating belt 302. Since the height of the push box 403 remains unchanged, the uniformity of the tea leaves stacking thickness can be ensured in the process of pushing the tea leaves, and excessive stacking can be prevented, thereby ensuring the overall consistency of the fermentation.

[0055] In the second step, when the push box 403 moves above the placement tray 2, its bottom is no longer in contact with the inside of the fermentation box 1. At this time, due to its own gravity effect, the dial head 15 slides downward along the connecting plate 503 and slides out of the bottom of the push box 403. In the process of the movement of the push box 403, the gear 17 and the tooth plate 16 produce a rotation effect due to the meshing, and the two bevel teeth 502 can be driven to rotate through the middle tooth 501, so that the two connecting plates 503 can be driven to slide back and forth alternately through the pull rod 14, and the tea pile can be dispersed by the dial head 15, ensuring that oxygen can be evenly in contact with the inside of the tea pile, further ensuring the fermentation effect;

[0056] In the third step, after the push box 403 moves from one end of the placement tray 2 to the other end, its bottom will slide to the bottom of the cleaning pad 601, and at this time the dial head 15 will be retracted into the inside of the push box 403, the dial head 15 prevents the adhered tea leaves from being scraped and gathered at the bottom of the push box 403, and the tea leaves at the bottom of the push box 403 can be cleaned by the cleaning pad 601, and with the rotation of the connecting ring 401, the clamping head 22 will be engaged with one side of the gear ring 21 and drive the gear ring 21 to rotate, and the transmission gear 19 can be driven to rotate by the connecting tooth 20, thereby driving the blowing plate 602 to slide in the direction close to the placement tray 2, and the tea leaves gathered on the surface of the cleaning pad 601 are pushed and scraped to the inside of the placement tray 2, because the steam passes into the inside of the fermentation box 1 through the blowing plate 602, while the blowing plate 602 pushes and scrapes the cleaning pad 601, the sprayed steam cooperates with the blowing plate 602 to clean the cleaning pad 601, thereby further improving the cleaning effect.

[0057] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
