Description

Technical Field

[0001] This utility model relates to the field of tea fermentation technology, and in particular to a fermentation device for tea processing. Background Technology

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea plant. Other names include cha, jia, ming, and chuan. Tea contains catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, all beneficial to health. Tea beverages are one of the world's three major beverages. The tea-making process involves withering, rolling, fermentation, and roasting. After rolling, the tea leaves are kept warm in fermentation equipment to ensure perfect fermentation. The degree of fermentation varies depending on the type of tea.

[0003] In the existing technology, there are certain shortcomings in the fermentation devices used in tea production. For example, fermentation machines are usually rectangular or cylindrical. Rectangular fermentation boxes are not convenient for turning the tea during the tea fermentation process. However, the different degrees of reaction between the inside and outside of the tea pile and oxygen will cause uneven fermentation. Cylindrical fermentation boxes can only rotate or stir the tea in a circular motion. Rotation cannot completely turn the tea, and stirring will waste the space where the tea is spread out. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fermentation device for tea processing, which has the advantages of easy turning and easy feeding, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a fermentation device for tea processing, comprising a base block, a fermentation box mounted on the top of the base block, the fermentation box comprising a fixed box body and a rotating box body, the fixed box body being fixedly mounted on the top of the base block, a hinge block being rotatably connected between the fixed box body and one side of the rotating box body, a pin connection device being installed on the top of the fixed box body and the rotating box body, the pin connection device comprising a pin, a sealing groove being provided on the end face of the rotating box body, a sealing strip being provided on the end face of the fixed box body, the sealing strip and the sealing groove being meshed in shape and size, a side block being fixedly mounted on the top of the base block on one side of the fermentation box, a forward and reverse reversing motor being fixedly mounted inside the base block below the side block, a transmission device being installed in a linear array inside the side block, a retaining ring being rotatably connected to one end of the transmission device, and a holding tray being placed on the inner ring of the retaining ring.

[0006] Through the above structural design, the tea leaves are fermented evenly by coordinating the forward and reverse motors, side blocks, and transmission devices. After the tea leaves are placed inside the holding tray, the forward and reverse rotation of the motor drives the worm gear to switch back and forth between forward and reverse rotation, causing the tea leaves inside the holding tray to move left and right, repeatedly switching between piling and spreading, thus increasing the contact area between the tea leaves and oxygen.

[0007] Preferably, the side block has a transmission cavity inside, the transmission cavity including a circular groove and a rectangular groove, the circular groove and the rectangular groove intersecting each other.

[0008] With the above structural design, the side block provides a transmission position between the forward and reverse motor and the transmission device through the transmission cavity, and the side block as a whole plays an auxiliary role in the transmission between the forward and reverse motor and the transmission device.

[0009] Preferably, the reversible motor is rotatably mounted with a worm gear between the circular slots of the transmission cavity, and the output shaft of the reversible motor is connected to the worm gear via a coupling.

[0010] With the above structural setup, the output shaft of the forward and reverse motor drives the worm gear to rotate through the coupling. The rotation of the worm gear drives the worm wheel to rotate, thus providing stable power for the tea fermentation process and facilitating uniform contact between the tea leaves and oxygen inside the holding tray.

[0011] Preferably, the transmission device includes a worm gear and a rotating shaft. The rotating shaft is rotatably mounted inside the side block and the fixed housing. The worm gear is fixedly mounted at the end of the rotating shaft. The worm gear is located inside the rectangular groove of the transmission cavity and meshes with the worm. The transmission device has a horizontally opened sliding groove inside and a slot is vertically opened at the top of the transmission device. The sliding groove and the slot are connected.

[0012] With the above structural configuration, the transmission device converts the worm's horizontal circumferential rotational power into vertical circumferential rotation by setting a worm wheel and a rotating shaft, with the worm wheel meshing with the worm. Then, the rotating shaft drives the retaining ring to sway left and right.

[0013] Preferably, a top head is slidably installed inside the groove, the end of the top head is inclined, a spring is fixedly connected between the middle side of the top head and the inner wall of the groove, and a top column is slidably installed inside the slot.

[0014] With the above structural design, the rotation between the transmission device and the retaining ring is restricted and released by the top head and the top column. When the top head is pressed into the retaining groove by the top column, the retaining ring cannot rotate on the outer ring of the retaining ring because it is restricted by the top head.

[0015] Preferably, the outer ring of the retaining ring is provided with a strip, and a retaining groove is provided on one side of the strip. The shape and size of the retaining groove are adapted to the top head. A retaining ring is rotatably sleeved between the inside of the strip of the retaining ring and the end of the rotating shaft.

[0016] With the above structural design, the retaining ring is locked in position through the engagement between the retaining groove and the top head. When the top head is inserted into the retaining groove, the retaining ring cannot be rotated.

[0017] This utility model has the following advantages:

[0018] 1. This tea processing fermentation device achieves uniform tea fermentation through a structure including side blocks, a forward and reverse motor, a transmission device, a retaining ring, and a holding tray. When the forward and reverse motor is started, its output shaft drives a worm gear to rotate within the circular groove of the transmission chamber via a coupling. The worm gear, in turn, drives a worm wheel to rotate circumferentially within the side block. The rotation of the worm wheel, through a rotating shaft, drives the retaining ring to rotate synchronously. The retaining ring, in turn, drives the holding tray to rotate. By switching between forward and reverse rotation via the output shaft of the forward and reverse motor, the worm gear drives the worm wheel to rotate synchronously, causing the rotating shaft to shake the tea leaves inside the holding tray from side to side. This repeated shaking alternating between piled and flat arrangement of the tea leaves increases the contact area between the tea leaves and oxygen, resulting in uniform tea fermentation.

[0019] 2. This tea processing fermentation device, through the design of a rotating shaft, top head, retaining ring, and retaining groove, facilitates the handling of the serving tray. First, open the rotating chamber, then pull the top column out of the slot. The end of the top head is no longer squeezed by the top column. Subsequently, the spring contracts due to its elasticity, causing the top head to move out of the retaining groove. At this time, rotate the retaining ring so that the retaining ring is located outside the fixed chamber. The user places the serving tray filled with tea inside the retaining ring. Then, rotate the retaining ring in the opposite direction to return it to its original position. Finally, insert the top column into the slot, so that the top head is squeezed into the retaining groove by the end of the top column, thus facilitating the user's handling of the serving tray.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 A fermentation device for tea processing includes a base block 1, with a fermentation box 2 mounted on top of the base block 1. The fermentation box 2 includes a fixed body 21 and a rotating body 22. The fixed body 21 is fixedly mounted on the top of the base block 1. A hinge block 23 rotatably connects the fixed body 21 and the rotating body 22 on one side, allowing the rotating body 22 to open and close with the fixed body 21 via the hinge block 23. A pin connection device 24 is mounted on the top of the fixed body 21 and the rotating body 22. The pin connection device 24 includes a pin 25, which enables the fixed body 21 to open and close. The connection between the box body 21 and the rotating box body 22 is locked. The end face of the rotating box body 22 is provided with a sealing groove 26. The end face of the fixed box body 21 is provided with a sealing strip 27. The sealing strip 27 and the sealing groove 26 are meshed in shape and size. The top of the bottom block 1 is fixedly installed on one side of the fermentation box 2. The inside of the bottom block 1 is fixedly installed below the side block 3. The inside of the side block 3 is equipped with a transmission device 5 in a linear array. One end of the transmission device 5 is rotatably connected to a retaining ring 6. The inner ring of the retaining ring 6 is filled with a holding tray 7.

[0029] In practical applications, this device achieves uniform fermentation of tea through the coordinated operation of components such as the reversible motor 4, side block 3, and transmission device 5. After the tea is placed inside the holding tray 7, the rotating chamber 22 is closed. Subsequently, through the effects of fresh air and humidification, the temperature and humidity inside the fermentation chamber 2 are made suitable for tea fermentation. By starting the reversible motor 4, the output shaft of the reversible motor 4 drives the worm gear 41 to rotate through the coupling. Since the worm gear 41 and the worm wheel 51 are meshed, the worm gear 41 drives the worm wheel 51 to rotate synchronously when it rotates. When the worm wheel 51 rotates, it is limited by the transmission device 5 and the retaining ring 6, causing the holding tray 7 to swing left and right inside the retaining ring 6. Through the forward and reverse rotation of the reversible motor 4, the worm gear 41 is driven to switch back and forth between forward and reverse rotation, causing the tea inside the holding tray 7 to move left and right, repeatedly switching between piling and spreading the tea, increasing the contact area between the tea and oxygen, and enabling the tea to ferment more evenly.

[0030] Simultaneously, the limiting connection between the transmission device 5 and the retaining ring 6 facilitates the user's placement of the tea tray 7 inside the retaining ring 6, eliminating the need for effort. By opening and rotating the housing 22, the top post 57 is pulled upwards from inside the slot 54, relieving the pressure on the top head 55. This causes the spring 56 to elastically contract, pushing the end of the top head 55 out of the retaining groove 61. Then, rotating the retaining ring 6 causes it to rotate circumferentially around the outer ring 62 via a strip, positioning it so that it faces outwards from the fixed housing 21. This allows the user to more easily place the tea tray 7 inside the retaining ring 6. After rotating the retaining ring 6 back, the top post 57 is inserted into the slot 54. The top head 55, pressed by the top post 57, is inserted into the retaining groove 61, effectively limiting the position of the transmission device 5 and the retaining ring 6 during tea fermentation.

[0031] Please see Figures 1-3 The side block 3 has a transmission cavity 31 inside, which includes a circular groove and a rectangular groove that intersect.

[0032] The side block 3 provides a transmission position between the forward and reverse motor 4 and the transmission device 5 through the transmission cavity 31. The side block 3 as a whole plays an auxiliary role in the transmission between the forward and reverse motor 4 and the transmission device 5.

[0033] Please see Figures 1-3 The forward and reverse motor 4 is rotatably mounted between the circular slots of the transmission cavity 31, and the output shaft of the forward and reverse motor 4 is connected to the worm 41 through a coupling.

[0034] The output shaft of the forward and reverse motor 4 drives the worm 41 to rotate through a coupling. The worm 41 meshes with the worm wheel 51, so the rotation of the worm 41 can drive the worm wheel 51 to rotate, thus providing stable power for the tea fermentation process and facilitating uniform contact between the tea leaves and oxygen inside the holding tray 7.

[0035] Please see Figures 1-6 The transmission device 5 includes a worm gear 51 and a rotating shaft 52. The rotating shaft 52 is rotatably installed inside the side block 3 and the fixed housing 21. The worm gear 51 is fixedly installed at the end of the rotating shaft 52. The worm gear 51 is located inside the rectangular groove of the transmission cavity 31 and meshes with the worm 41. A sliding groove 53 is horizontally opened inside the transmission device 5. A slot 54 is vertically opened on the top of the transmission device 5. The sliding groove 53 and the slot 54 are connected.

[0036] The transmission device 5, by setting a worm gear 51 and a rotating shaft 52, with the worm gear 51 meshing with the worm 41, converts the horizontal circumferential rotation of the worm 41 into vertical circumferential rotation. Then, the rotating shaft 52 drives the retaining ring 6 to shake left and right. After the tea leaves are shaken left and right inside the holding tray 7, they switch back and forth between being piled up and laid flat. This method can increase the reaction area of ​​the tea pile with oxygen, so that the tea leaves can ferment evenly.

[0037] Please see Figures 1-6 A top head 55 is slidably installed inside the slide groove 53. The end of the top head 55 is inclined. A spring 56 is fixedly connected between the middle side of the top head 55 and the inner wall of the slide groove 53. A top post 57 is slidably installed inside the slot 54. When the top post 57 is pressed down inside the slot 54, the end of the top post 57 presses against the inclined surface of the top head 55, and the top head 55 slides into the slide groove 53 by being pressed by the top post 57.

[0038] By setting the top head 55 and the top post 57, the rotation between the transmission device 5 and the retaining ring 6 is restricted and released. When the top head 55 is pressed into the slot 61 by the top post 57, the retaining ring 6 cannot rotate on the outer ring of the collar 62 because it is restricted by the top head 55. When it is necessary to place or remove the tray 7, by pulling out the top post 57 from the position inside the slot 54, the top head 55 receives the contraction force of the spring 56, and the top head 55 is no longer inserted into the slot 61. Then the retaining ring 6 can rotate in a circle around the collar 62, so that it is easy to pick up and put down the tray 7.

[0039] Please see Figures 1-6 The outer ring of the retaining ring 6 is provided with a strip, and a groove 61 is provided on one side of the strip. The groove 61 is adapted to the shape and size of the top head 55. A collar 62 is rotatably sleeved between the inside of the strip of the retaining ring 6 and the end of the rotating shaft 52. The collar 62 restricts the position between the transmission device 5 and the retaining ring 6, and can only rotate on the outer ring of the collar 62.

[0040] The retaining ring 6 is locked in position by engaging with the top head 55 through the retaining groove 61. When the top head 55 is inserted into the retaining groove 61, the retaining ring 6 cannot be rotated. When the top head 55 is removed from the retaining groove 61, the retaining ring 6 can be rotated to the outside of the rotating housing 22, which makes it convenient for the user to take out or place the tray 7 from inside the retaining ring 6.

[0041] Working principle: When in use, first open the rotating box 22, then pull the top post 57 out of the slot 54. The end of the top head 55 is no longer squeezed by the top post 57. Then, the spring 56 contracts due to its elasticity, which drives the top head 55 to move out of the slot 61. At this time, rotate the angle of the retaining ring 6 so that the retaining ring 6 is located outside the fixed box 21. The user places the tray 7 filled with tea leaves inside the retaining ring 6. Then rotate the retaining ring 6 in the opposite direction so that the retaining ring 6 returns to its original position. Then insert the top post 57 into the slot 54 so that the top head 55 is squeezed into the slot 61 by the end of the top post 57, thereby limiting the position of the retaining ring 6.

[0042] After the user places the inside of the retaining ring 6 into the holding tray 7, the rotating box 22 is closed, and the connection between the fixed box 21 and the rotating box 22 is locked using the pin connection device 24. Due to the sealing of the sealing groove 26 and the sealing strip 27, leakage of internal temperature and humidity is prevented inside the fermentation box 2. Then, the forward and reverse motor 4 is started. The output shaft of the forward and reverse motor 4 drives the worm gear 41 to rotate inside the circular groove of the transmission cavity 31 via a coupling. The worm gear 41 meshes with the worm wheel 51. When the worm gear 41 rotates, it drives the worm wheel 51 to rotate circumferentially inside the side block 3. When in motion, the rotating shaft 52 drives the retaining ring 6 to rotate synchronously. Because the top column 57 presses the top head 55 to lock the position of the retaining ring 6, the retaining ring 6 will not make any other movements. During the rotation of the retaining ring 6, the holding tray 7 will rotate. The output shaft of the forward and reverse motor 4 switches back and forth between forward and reverse rotation, so that the worm gear 41 drives the worm wheel 51 to rotate synchronously, thereby causing the rotating shaft 52 to drive the tea leaves inside the holding tray 7 to shake left and right instead of flipping. This causes the tea leaves to repeatedly switch between being piled up and laid flat. During the shaking process, the contact area between the tea leaves and oxygen increases, which can carry out uniform fermentation.
