Description

Technical Field

[0001] This application relates to the field of tea fermentation and processing technology, and in particular to a device for yellowing Huangda tea that is easy to turn over. Background Technology

[0002] Lushan is famous for its tea, and Huangda tea is one of the varieties. Huangda tea is a type of tea that is fermented and processed using a special technique, among which the "yellowing" process is the key step that determines its quality.

[0003] During the yellowing process of Huangda tea, the tea leaves need to be turned regularly to ensure that they are heated and oxygenated evenly, and to avoid over- or under-fermentation in some areas. Traditionally, Huangda tea is yellowed using a single fixed trough. When turning the tea leaves, operators need to use tools to repeatedly turn them over. This is not only labor-intensive, but also results in poor uniformity of turning due to the depth of the single-layer trough. This can easily lead to the problem of "the surface being thoroughly turned over while the bottom layer is left untouched," resulting in inconsistent fermentation levels and affecting the taste and color of the finished product.

[0004] In summary, the existing technology for yellow tea often uses a single vat for yellowing, which leads to high labor intensity in turning the pile and uneven turning. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this application is to solve the problems of high labor intensity and uneven turning during the fermentation of Huangda tea. Compared with the prior art, this application provides a Huangda tea fermentation device that is easy to turn. By setting multiple shallow fermentation tanks, it is easy to turn the tea leaves in each fermentation tank, so that the turning is more thorough and more uniform.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0007] A device for easily turning and fermenting Huangda tea leaves, comprising: The cavity has an opening on one vertical side, and sealing doors are rotatably connected to both sides of the cavity at the opening via hinges. Multiple pairs of pull-out mechanisms are provided on the side wall of the cavity.

[0008] A fermentation tray is connected between a pair of the aforementioned pull-out mechanisms, and the fermentation tray is slidably connected to the inner wall of the trough cavity through the pull-out mechanisms.

[0009] A tea-turning board has rotating shafts fixed at both ends. The tea-turning board is rotatably set inside the fermentation tray via the rotating shafts. The rotating shaft at the end of the tea-turning board near the sealing door passes through the side wall of the fermentation tray and extends to the outside of the fermentation tray.

[0010] Furthermore, multiple fermentation trays are provided, and the multiple fermentation trays are evenly distributed along the height direction of the trough. The number of multiple fermentation trays corresponds to the number of multiple pairs of pull-out mechanisms. The multiple tea-turning plates are all perpendicular to the fermentation trays in the initial state.

[0011] Furthermore, multiple tea-turning boards are provided, and the multiple tea-turning boards are evenly distributed along the length direction of the fermentation tray.

[0012] Furthermore, the height of the tea-turning board is the same as the depth of the fermentation tray.

[0013] Furthermore, the pull-out mechanism is a ball bearing pull-out mechanism, which has a fixed part and a sliding part. The fixed part is fixedly connected to the trough cavity, and the sliding part is fixedly connected to the outer wall of the fermentation tray. The sliding part can slide back and forth along the fixed part.

[0014] Furthermore, densely packed ventilation holes are provided at the bottom of the fermentation pan and on the tea-turning plate.

[0015] Furthermore, a worm gear is fixed to one end of the tea-turning board located outside the fermentation tray, and a worm is engaged with one side of the worm gear. The worm is rotatably connected to the outer wall of the fermentation tray, and the worm engages with multiple worm gears. Compared with the prior art, the advantages of this application are: By setting multiple fermentation trays inside the fermentation tank, the thickness of the tea leaves is reduced, making it easier to turn them over. Multiple rotating tea-turning plates are set inside the fermentation trays, with the height of the tea-turning plates being the same as the depth of the fermentation trays. When the multiple tea-turning plates are rotated horizontally to the horizontal position, the total area of ​​the multiple tea-turning plates connected together is the same as the internal area of ​​the fermentation tank. Therefore, by rotating the multiple tea-turning plates, the tea leaves in the entire fermentation tank can be turned over completely, thereby achieving thorough turning of the tea leaves and making the turning of the tea leaves more thorough and uniform.

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] This utility model provides a device for easily turning over and fermenting Huangda tea leaves. Please refer to [link / reference]. Figure 1-4 The main method involves setting up multiple shallow fermentation trays in the fermentation tank, placing the tea leaves in these trays for yellowing. This setup ensures that the tea leaves are shallow enough to be easily turned over, and that both the surface and bottom layers of tea leaves are easily moved, resulting in a more even and thorough turning process.

[0020] The yellowing device includes: a trough body 1 with an opening on one vertical side; sealing doors 2 are rotatably connected to both sides of the trough body 1 at the opening via hinges; and multiple pairs of pull-out mechanisms 3 are provided on the side wall of the trough body 1.

[0021] The pull-out mechanism 3 is a ball-bearing pull-out mechanism 3. The ball-bearing pull-out mechanism 3 has a fixed part and a sliding part. The fixed part is fixedly connected to the cavity 1, and the sliding part is fixedly connected to the outer wall of the fermentation tray 4. The sliding part can slide back and forth along the fixed part.

[0022] Fermentation tray 4 is connected between a pair of pull-out mechanisms 3. Fermentation tray 4 is slidably connected to the inner wall of tank cavity 1 through pull-out mechanisms 3.

[0023] There are multiple fermentation trays 4, which are evenly distributed along the height of the tank cavity 1. The number of fermentation trays 4 corresponds to the number of multiple pairs of pull-out mechanisms 3.

[0024] The tea-turning board 5 has rotating shafts fixed at both ends. The tea-turning board 5 is rotated and set inside the fermentation tray 4. The rotating shaft at the end of the tea-turning board 5 near the sealing door 2 passes through the side wall of the fermentation tray 4 and extends to the outside of the fermentation tray 4.

[0025] Multiple tea-turning boards 5 are provided, and the multiple tea-turning boards 5 are evenly distributed along the length of the fermentation tray 4, and the multiple tea-turning boards 5 are perpendicular to the fermentation tray 4 in the initial state.

[0026] The height of the tea-turning board 5 is the same as the depth of the fermentation tray 4.

[0027] The rotating shaft is fixed with a handle on one end outside the fermentation tray 4, which is easy to rotate, so that the tea can be turned by manually rotating the tea-turning board 5.

[0028] When the multiple tea-turning plates 5 are rotated horizontally to a horizontal position, the total area of ​​the multiple tea-turning plates 5 connected together is the same as the internal area of ​​the fermentation tank.

[0029] Using this method, first, the fermentation tray 4 is pulled out from the trough 1, the tea turning board 5 is adjusted to be perpendicular to the fermentation tray 4, then the tea cakes are evenly placed into the fermentation tray 4, and then the fermentation tray 4 is pushed back into the trough 1 to start the yellowing process.

[0030] When turning the tea, the turning plate 5 is rotated by rotating the shaft, which turns the tea cake inside the fermentation tray 4. Since the height of the turning plate 5 is the same as the depth of the fermentation tray 4, the turning plate 5 can pass through the bottom of the fermentation tray 4 when it rotates, and can turn the tea cake at the bottom of the fermentation tray 4 upward. When multiple turning plates 5 are in a horizontal state, they can cover the entire fermentation tank, so that the tea cake in the entire fermentation tank can be turned over completely, thereby achieving a thorough turning of the tea cake, making the turning of the tea cake more thorough and more uniform.

[0031] The multiple fermentation trays reduce the thickness of the tea cake, so that the thickness of the tea cake is smaller each time it is turned, and the amount of tea cake turned is also smaller, making it easier and more convenient to turn the tea.

[0032] In addition, the fermentation tray 4 can be removed and its position changed. For example, the upper fermentation tray 4 can be moved to the lower layer, and the lower fermentation tray 4 can be moved to the upper layer. This can overcome the phenomenon that the fermentation degree of tea leaves in different fermentation trays 4 is inconsistent due to different fermentation temperatures in different positions, and make the fermentation of tea leaves more uniform.

[0033] Multiple tea-turning plates 5 can thoroughly turn the tea leaves inside the fermentation tray 4, but turning them one by one is cumbersome. Therefore, the following preferred embodiment is provided: Specifically, a worm gear 6 is fixed at one end of the tea-turning board 5 located outside the fermentation tray 4, and a worm 7 is engaged on one side of the worm gear 6. The worm 7 is rotatably connected to the outer wall of the fermentation tray 4, and the worm 7 is engaged with multiple worm gears 6.

[0034] The worm gear 7 can be connected to a hand crank or a motor, as long as it is convenient to drive the worm gear 7 to rotate.

[0035] A protective cover is provided on the outside of the worm gear 6 and the worm 7 to cover them and prevent tea leaves from falling into them and affecting the transmission. The protective cover is not shown in the figure for the sake of showing the structure.

[0036] In this way, by rotating the worm 7, multiple worm wheels 6 can be driven to rotate simultaneously, thereby driving multiple tea-turning plates 5 to rotate simultaneously to turn the tea, thus increasing the tea-turning speed and making tea-turning faster and more convenient.

[0037] To facilitate airflow between the upper and lower fermentation trays 4 and improve the uniformity of fermentation, the following preferred embodiments are provided: Specifically, dense ventilation holes 8 are provided at the bottom of the fermentation tray 4 and the tea turning plate 5.

[0038] By using this method, the air vents increase the airflow between the fermentation trays 4, which makes the fermentation temperature of the upper and lower fermentation trays 4 closer and further improves the uniformity of fermentation.

[0039] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
