Description

Technical Field

[0001] The present invention relates to the technical field of tea processing, and particularly relates to an automated device for sorting and pre-cooling tea. Background Art

[0002] In the prior art, for harvested tea leaves, from the same tea tree, the sizes and shapes of the harvested tea leaves are different, and the grades of the products made are also different. Therefore, the sorting of tea leaves is a very crucial stage in the tea-making process. When making tea, for leaves of different sizes, their concentrations, flavors, colors, and the speeds of dissolving in boiling water are different. The larger the leaf, the longer the dissolution time, and vice versa. It is very important that the leaves used to brew the same pot of tea have the same size. Each brewing particle must be of uniform size, and before production, it is necessary to screen according to the size of the tea leaves. In the prior art, when harvesting tea leaves, the tea leaves are all placed in a tea-picking basket, causing the tea leaves to pile up, resulting in a high internal temperature of the tea leaves, easy spoilage, short shelf life, and generally, tea trees are on mountains and need to be transported, so during transportation, they are jolted on mountain roads, further increasing the internal temperature of the tea leaves; and after being transported to the tea processing factory, the fresh tea leaves are generally unloaded from the vehicle and piled up aside waiting for further sorting. At this time, the accumulated heat will increase the possibility of spoilage of the fresh tea leaves. Therefore, an automated device for sorting and pre-cooling tea that can achieve sorting and rapidly cool the tea leaves at the same time is needed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to provide an automated device for sorting and pre-cooling tea that can achieve sorting and rapidly cool the tea leaves at the same time.

[0004] To solve the above technical problem, the technical solution adopted by the present invention is as follows:

The outer roller is rotatably connected to the support shaft. The motor drives the outer roller to rotate. There is an accommodation space between the outer roller and the support shaft. A rotating cooling roller and a rotating heating roller are arranged in the accommodation space. The cooling roller is arranged on one side of the outer roller facing the interval and is attached to the inner side wall of the outer roller. The heating roller is arranged on the other side and is attached to the inner side wall of the outer roller.

[0009] Preferably, the operating temperature of the cooling roller is 0°C - 5°C.

[0010] Preferably, one end of the bracket corresponding to the end is a rotating end, and the other end is an adjusting end. The rotating end is rotatably connected to the frame. An adjusting frame and a locking member are arranged on the adjusting end. The adjusting frame is arranged on the frame. An oval long hole is arranged on the adjusting frame. The locking member is fixed on the adjusting frame and is locked after being inserted into the oval long hole.

[0011] Preferably, horizontal adjusting grooves are respectively arranged on the rotating end and the adjusting end of the bracket. Adjusting handles are respectively arranged at both ends of the second roller body. The adjusting handle includes a screw rod, a rotating disk and a slider. A rotating hole is arranged on the slider. A universal bearing cooperating with the second roller body is arranged in the rotating hole. The slider is sleeved on the outer periphery of the second roller body through the universal bearing.

The rotating disk is rotatably connected to the side wall of the bracket corresponding to the horizontal adjusting groove. A through hole for the screw rod to pass through is arranged on the side wall of the bracket corresponding to the horizontal adjusting groove. One end of the screw rod is connected to the side wall of the slider, and the other end passes through the through hole and is in threaded cooperation with the adjusting hole of the rotating disk. When the rotating disk of the adjusting handle rotates, it drives the slider to move, thereby adjusting the positions of both ends of the second roller body in the horizontal adjusting groove.

[0012] Preferably, a corresponding pull-out groove is arranged on the bracket below the collection groove.

[0013] Preferably, a support plate corresponding to the pull-out groove is arranged on the bracket. A track cooperating with the pull-out groove is arranged on the support plate. A handle is arranged on the pull-out groove.

[0014] Preferably, flexible heat-conducting layers are arranged on the surfaces of both the cooling roller and the heating roller. Both the cooling roller and the heating roller are attached to the inner surface of the inner wall of the outer roller.

[0018] The beneficial effects of the present invention are as follows: the interval changes from small to large from the beginning to the end; the starting end is inclined from top to bottom toward the end; in conjunction with the counterclockwise rotation of the first roller body, the clockwise rotation of the second roller body and the arrangement of the heating roller and the refrigeration roller, since the fresh tea leaves are all in the form of flakes, the fresher the tea leaves, the thinner they are, and the older the tea leaves, the thicker they are, the interval changes from small to large, in conjunction with the rotation of the first roller body and the second roller body in the direction of the interval, the fresh tea leaves will move toward the top of the interval, and since the fresh tea leaves cannot have completely equal weight on both sides, the fresh tea leaves will be rotated into a vertical state under the action of the first roller body and the second roller body, and then pass through the interval in a vertical state into the collecting tank; and the refrigeration roller can cool the outer roller that contacts the tea leaves, absorb the heat generated due to various reasons, and the low temperature of the outer roller can make the moisture on the fresh tea leaves condense or take away part of the moisture due to contact with the surface of the outer roller, thereby facilitating the subsequent fresh tea leaves. The withering or frying of green tea leaves can improve the processing efficiency of tea leaves. At the same time, the setting of the heating roller can heat the surface of the outer roller containing water, so that the water evaporates quickly, ensuring that the outer roller can be cooled in the next circle. The automatic device for tea sorting and pre-cooling can take away heat and excess water while sorting, ensuring the quality of the tea leaves while retaining the original flavor of the tea leaves: low-temperature dehydration can reduce the content of pectin and some proteins that are easily soluble in the tea leaves, ensuring the concentration of various substances contained in the tea leaves during processing; low-temperature treatment can extend the storage period of fresh leaves after harvesting, while ensuring or even improving the sensory quality of green tea, and having a positive impact on the aroma quality of tea products; low-temperature dehydration avoids the decomposition of theaflavins and thearubigins at high temperatures, as well as changes in the structures of carotenoids and chlorophyll, thereby maintaining the color of the tea soup; it can also reduce the loss of aroma components and maintain the aroma of the tea soup.

Specific embodiments

[0025] To describe in detail the technical content, achieved objectives and effects of the present invention, the following is described in conjunction with embodiments and with reference to the accompanying drawings.

[0026] Please refer to Figures 1 to 3 , an automatic device for tea sorting and pre-cooling, including a frame 1, a feeder 2 and a sorting and pre-cooling assembly 3; the feeder 2 and the sorting and pre-cooling assembly 3 are arranged on the frame 1;

[0027] The sorting and pre-cooling assembly 3 includes a bracket 31, a motor 32, a first roller 33 and a second roller 34. The first roller 33 and the second roller 34 are rotatably arranged on the bracket 31. There is an interval 4 between the first roller 33 and the second roller 34. One end of the interval 4 facing the feeder 2 is the starting end, and the end far from the feeder 2 is the ending end; the interval 4 changes from small to large from the starting end to the ending end; the starting end to the ending end is inclined from top to bottom; a plurality of collection tanks 11 are arranged on the frame 1 below the interval 4;

[0028] The bracket 31 is arranged on the frame 1. Taking the ray formed in the direction from the starting end to the ending end as the reference line 5, the first roller 33 is on the left side of the reference line 5, and the second roller 34 is on the right side of the reference line 5. The motor 32 drives the first roller 33 to rotate counterclockwise, and the motor 32 drives the second roller 34 to rotate clockwise;

[0029] The structures of the first roller body 33 and the second roller body 34 are mirror images. The first roller body 33 includes an outer roller 331 and a support shaft 332. The outer roller 331 is rotatably connected to the support shaft 332. The motor 32 drives the outer roller 331 to rotate. There is an accommodating space 333 between the outer roller 331 and the support shaft 332. A rotating cooling roller 334 and a rotating heating roller 335 are arranged in the accommodating space 333. The cooling roller 334 is arranged on the side of the outer roller 331 facing the interval 4 and is in contact with the inner wall of the outer roller 331. The heating roller 335 is arranged on the other side and is in contact with the inner wall of the outer roller 331.

[0030] The working process includes: the tea leaves are placed on the feeder 2, and the feeder 2 starts to convey the tea leaves. Since the interval 4 changes from small to large from the beginning to the end, that is, it is V-shaped, the older the tea leaves are, the thicker they are, and the fresher the tea leaves are, the thinner they are. In conjunction with the counterclockwise rotation of the first roller body 33 and the clockwise rotation of the second roller body 34, the tea leaves can stand up, and then the standing tea leaves can fall from the interval 4. This is the same as the existing fruit size screening. The V-shaped interval 4 can correspond to tea leaves of different thicknesses to achieve the sorting purpose.

[0031] As can be seen from the above description, the interval 4 changes from small to large from the beginning to the end; the beginning is inclined from top to bottom toward the end; in conjunction with the counterclockwise rotation of the first roller body 33, the clockwise rotation of the second roller body 34 and the arrangement of the heating roller 335 and the refrigeration roller 334, since the fresh tea leaves are all in the form of flakes, the fresher the tea leaves, the thinner they are, and the older the tea leaves, the thicker they are, the interval 4 changes from small to large, in conjunction with the rotation of the first roller body 33 and the second roller body 34 in the direction of the interval 4, the fresh tea leaves will move toward the top of the interval 4, and since the fresh tea leaves cannot have completely equal weight on both sides, the fresh tea leaves will be rotated into a vertical state under the action of the first roller body and the second roller body, and then pass through the interval 4 in a vertical state into the collecting tank 11, and the fresh tea leaves will not be squeezed and damaged, and the refrigeration roller 334 can cool the outer roller 331 that the tea leaves contact can absorb the heat generated due to various reasons, and the low temperature of the outer roller 331 can make the moisture on the fresh tea leaves condense or be absorbed by the outer roller 331 due to contact with the surface of the outer roller 331 After contact, roller 331 takes away a part of the moisture, which facilitates the subsequent withering or frying of fresh tea leaves and improves the tea processing efficiency; at the same time, through the setting of the heating roller 335, the surface of the outer roller 331 containing moisture can be heated, so that the moisture evaporates quickly, ensuring that the outer roller 331 can be cooled in the next round; through the operation of the automatic device for tea sorting and pre-cooling, heat and excess moisture can be taken away during sorting, which can ensure the quality of the tea while retaining the original flavor of the tea: low-temperature dehydration can reduce the precipitation of pectin and part of the protein in the tea leaves, and ensure the concentration of various substances contained in the tea leaves during processing; low-temperature treatment can extend the spreading period of fresh leaves after harvesting, while ensuring or even improving the sensory quality of green tea, and having a positive impact on the aroma quality of tea products; low-temperature dehydration avoids the decomposition of theaflavins and thearubigins at high temperatures, as well as changes in the structures of carotenoids and chlorophyll, thereby maintaining the color of the tea soup; it can also reduce the loss of aroma components and maintain the aroma of the tea soup.

[0032] Furthermore, the operating temperature of the refrigeration roller 334 is 0°C-5°C.

[0033] From the above description, it can be seen that by keeping the operating temperature above 0°C, ice can be prevented from sticking to the fresh tea leaves.

[0034] Furthermore, one end of the bracket 31 corresponding to the end is a rotating end 311, and the other end is an adjusting end 312. The rotating end 311 is rotatably connected to the frame 1, and the adjusting end 312 is provided with an adjusting frame 35 and a locking piece 36. The adjusting frame 35 is arranged on the frame 1, and a waist-shaped long hole 351 is arranged on the adjusting frame 35. The locking piece 36 is fixed on the adjusting frame 35 and locked after being inserted into the waist-shaped long hole.

[0035] It can be seen from the above description that the inclination of the entire bracket 31 and the components arranged on the bracket 31 can be adjusted as needed through the adjustment frame 35 and the locking member 36.

[0036] Further, horizontal adjustment grooves 37 are respectively provided on the rotating end 311 and the adjusting end 312 of the bracket 31. Adjusting handles 38 are respectively provided at both ends of the second roller body 34. The adjusting handle includes a screw 381, a rotating disk 382 and a slider 383. A rotating hole is provided on the slider 383, and a universal bearing 384 cooperating with the second roller body is provided in the rotating hole. The slider 383 is sleeved on the outer periphery of the second roller body 34 through the universal bearing 384. Sliding grooves 387 are respectively provided at the top and bottom of the slider 383, and the slider 383 slides in the horizontal adjustment groove through the sliding grooves 387. An adjustment hole 385 for the screw 381 to pass through is provided in the middle of the rotating disk 382, and threads cooperating with the screw 381 are provided on the inner side wall of the adjustment hole 385. The rotating disk 382 is rotatably connected to the side wall of the bracket 31 corresponding to the horizontal adjustment groove 37, and a through hole 386 for the screw 381 to pass through is provided on the side wall of the bracket 31 corresponding to the horizontal adjustment groove 37. One end of the screw 381 is connected to the side wall of the slider 383, and the other end passes through the through hole 386 and is in threaded cooperation with the adjustment hole of the rotating disk 382. When the rotating disk 382 of the adjusting handle 38 rotates, it drives the slider 383 to move, thereby adjusting the positions of both ends of the second roller body 34 in the horizontal adjustment groove 37.

[0037] The working process of the adjusting handle 38 includes: the adjusting handles 38 at both ends of the second roller body 34 respectively rotate their respective rotating disks 382, so that the position of the screw 381 changes, thereby driving the slider 383 to move in the horizontal adjustment groove 37, and then enabling both ends of the second roller body 34 to move in the horizontal adjustment groove 37 respectively. The moving distance is determined by the number of turns of the rotation of the rotating disks 382 of their respective adjusting handles 38. The adjustment interval 4 changes from small to large from the starting end to the ending end, that is, the included angle of the V shape formed by the first roller body and the second roller body is adjusted. The universal bearing 384 can adapt to the change of the included angle of the V shape to prevent the slider 383 from being unable to move.

[0038] Further, a corresponding draw-out groove 12 is provided on the bracket 31 below the collection groove 11.

[0039] As can be seen from the above description, through the provision of the draw-out groove 12, the sorted and collected tea leaves can be further processed.

[0040] Further, a support plate 13 corresponding to the draw-out groove 12 is provided on the bracket 31. A track 14 cooperating with the draw-out groove 12 is provided on the support plate 13. A handle 15 is provided on the draw-out groove 12.

[0041] As can be seen from the above description, by setting the track 14, the efficiency can be improved and the extraction of the pull-out slot 12 can be facilitated. By setting the handle 15, the pulling of the pull-out slot 12 can be facilitated.

[0042] Further, flexible heat-conducting layers 336 are provided on the surfaces of the refrigerating roller 334 and the heating roller 335, and the refrigerating roller 334 and the heating roller 335 are both attached to the inner wall surface of the outer roller 331.

[0043] As can be seen from the above description, through the flexible heat-conducting layer 336, the contact area between the surface and the inner wall of the outer roller 331 can be made larger, so that the heat-conducting effect is better, and the refrigerating or heating effect is improved.

[0044] Further, two converging plates 39 are provided above the space 4, and the two converging plates 39 are arranged in a V shape.

[0045] As can be seen from the above description, through the setting of the converging plates 39, fresh tea leaves can be conveniently fed into the space 4.

[0046] Further, the feeder 2 is a vibrating feeder 2, and the vibrating feeder 2 and the bracket 31 are both rigidly connected to the frame 1.

[0047] As can be seen from the above description, since the feeder 2 and the sorting and pre-cooling assembly 3 are both arranged on the frame 1 and rigidly connected, the vibration of the vibrating feeder 2 can be transmitted to the bracket 31 through the frame 1, and then transmitted to the first roller 33 and the second roller 34, forming vibration at the space 4, thereby improving the sorting effect. The shock-absorbing base of the vibrating feeder 2 can also be directly removed to enhance the vibration effect.

[0048] Further, shock-absorbing blocks 16 are provided at the bottom of the frame 1.
