Description

Technical Field

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

[0002] Tea is a beverage ingredient made from the tender leaves and buds of the tea plant.

[0003] The main functions of stir-frying tea leaves during processing are as follows: First, stir-frying dries the tea leaves, making them easier to preserve; second, during the stir-frying process, high temperatures are used to destroy and deactivate the oxidase activity in the fresh leaves, preventing excessive fermentation and preserving the color and aroma of the tea, such as the emerald green and fragrant aroma of green tea.

[0004] Currently, tea drying equipment mainly consists of a barrel, a heating structure, and a stirring mechanism. The heating structure heats the barrel and the tea leaves inside, while the stirring mechanism agitates the tea to achieve the purpose of drying. However, the stirring mechanism can only stir in one position and cannot change the stirring position, resulting in uneven heating of the tea. Only the tea leaves around the stirring position are fully turned over, while the tea leaves in other positions may be overheated or underheated due to prolonged exposure to the bottom of the barrel. Overheating can cause the tea to burn, damaging the taste and aroma and reducing the quality of the tea. At the same time, current tea drying equipment usually only has the function of frying tea and cannot separate small pieces of tea leaves from the finished tea, making it relatively poor in terms of practicality and functionality.

[0005] Therefore, a tea-drying device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a tea-drying device to solve the above-mentioned problems.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A tea drying device includes a base plate, a drying cylinder on top of the base plate, and arc-shaped openings on both the front and rear sides of the base plate. The inner walls of the two arc-shaped openings are respectively provided with a first screen and a second screen, the mesh size of the first screen being larger than that of the second screen. Connecting frames, whose lower ends are connected to the top of the base plate, are rotatably fitted at both ends of the drying cylinder. An angle adjustment mechanism for rotating the drying cylinder is provided between the top of the base plate and the right side of the drying cylinder. A bushing sleeve extends through to the right side of the drying cylinder and is rotatably connected to the through-hole. A horizontal shaft extends to the left side of the bushing sleeve. A connecting block is rotatably connected to the left end of the horizontal shaft. Multiple strip-shaped openings are evenly distributed on the outer surface of the bushing sleeve. Multiple stirring rods, each passing through one of the multiple strip-shaped openings, are provided on the outer surface of the horizontal shaft. A reciprocating mechanism is provided between the left side of the connecting block and the outer side of the base plate. A driving mechanism is provided between the outer side of the base plate and the left end of the bushing sleeve.

[0009] Preferably, the angle adjustment mechanism includes a bracket, a connecting shaft, and a motor. The bracket is located on the right side of the top of the base plate, and the connecting shaft is located on the right side of the stir-frying drum, extending through to the right side of the bracket and rotatably connected to the through-hole. The bracket is equipped with a motor whose output shaft is coaxially connected to the right end of the connecting shaft.

[0010] Preferably, the reciprocating mechanism includes an L-shaped frame, a transverse rod, a support frame, a second motor, a driving plate, and a driven plate. The top of the base plate is provided with an L-shaped frame, and the left side of the connecting block is provided with a transverse rod. A support frame with one end connected to the outside of the L-shaped frame is slidably sleeved on the transverse rod. The rear side of the L-shaped frame is provided with a driving plate through which the output shaft passes. A driven plate is rotatably connected between the upper end of the driving plate and the left end of the transverse rod.

[0011] Preferably, the drive mechanism includes a mounting frame, a third motor, a main gear, and a driven gear. The mounting frame is provided on the top of the base plate, and the third motor is provided on the top of the mounting frame. The output shaft of the third motor and the left end of the bushing are respectively provided with the main gear and the driven gear, and the main gear and the driven gear mesh with each other.

[0012] Preferably, a heater is provided at the bottom of the stir-frying drum.

[0013] Preferably, the top of the stir-frying drum is provided with a drum cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the drive mechanism drives the bushing, stirring rod, and horizontal shaft to rotate, so as to stir the tea leaves at the same position in the drying drum. The reciprocating mechanism drives the horizontal shaft and connecting block to rotate back and forth, so that the stirring rod on the horizontal shaft moves back and forth along the strip opening to stir the tea leaves at different positions in the drying drum. This ensures that the tea leaves at each position are fully stirred and turned, so that the tea leaves are heated evenly and dried evenly, thus improving the quality of the tea leaves. The angle adjustment mechanism can rotate the drying drum 90° clockwise or counterclockwise to use the large-diameter screen one and the small-diameter screen two to sieve the tea leaves, so as to separate the fine powder tea leaves and small pieces of tea leaves, thus improving the practicality and functionality of the equipment.

[0025] In this embodiment, by Figure 1-4 This invention discloses a tea drying device, comprising a base plate 1, a drying cylinder 21 mounted on top of the base plate 1, and arc-shaped openings 23 on both the front and rear sides of the base plate 1. The inner walls of the two arc-shaped openings 23 are respectively provided with a first screen 24 and a second screen 25, the mesh size of the first screen 24 being larger than that of the second screen 25. Connecting frames 26, whose lower ends are connected to the top of the base plate 1, are rotatably fitted at both ends of the drying cylinder 21. An angle adjustment mechanism 4 for rotating the drying cylinder 21 is provided between the top of the base plate 1 and the right side of the drying cylinder 21. The cylinder 21 has a sleeve 51 that extends to its right and is rotatably connected to the through point. The sleeve 51 has a horizontal shaft 52 extending to its left. The left end of the horizontal shaft 52 is rotatably connected to a connecting block 53. The outer surface of the sleeve 51 has multiple slots 54 evenly distributed. The outer surface of the horizontal shaft 52 has multiple stirring rods 55 that pass through the multiple slots 54. A reciprocating mechanism 6 is provided between the left side of the connecting block 53 and the outer side of the bottom plate 1. A driving mechanism 7 is provided between the outer side of the bottom plate 1 and the left end of the sleeve 51.

[0026] In this embodiment, the drive mechanism 7 can drive the bushing 51 to rotate. Simultaneously, the limiting cooperation between the strip-shaped opening 54 and the stirring rod 55 drives the stirring rod 55 and the horizontal shaft 52 to rotate, thus stirring the tea leaves at the same location in the drying drum 21. At the same time, the reciprocating mechanism 6 drives the horizontal shaft 52 and the connecting block 53 to rotate reciprocally, causing the stirring rod 55 on the horizontal shaft 52 to move reciprocally along the strip-shaped opening 54, thus stirring the tea leaves at different locations in the drying drum 21. This ensures that the tea leaves at each location are fully stirred and agitated, preventing them from remaining stuck to the inner wall of the drying drum 21 for extended periods. If the tea leaves do not come into contact with the inner wall of the drying drum 21 for an extended period, they may overheat or scorch. This ensures even heating and drying, improving the quality of the tea. After the tea is fried, the drying drum 21 is rotated 90° clockwise or 90° counterclockwise using the angle adjustment mechanism 4. This allows the tea leaves to be sieved using screens 24 and 25. Since the mesh size of screen 24 is larger than that of screen 25, fine powder and small pieces of tea leaves can be separated, improving the practicality and functionality of the equipment.

[0027] Preferably, as another embodiment of the present invention, the angle adjustment mechanism 4 includes a bracket 41, a connecting shaft 42 and a motor 43. The bracket 41 is provided on the right side of the top of the base plate 1, and the connecting shaft 42 is provided on the right side of the dry-frying drum 21, which passes through to the right side of the bracket 41 and is rotatably connected to the through-hole. The bracket 41 is provided with a motor 43 whose output shaft is coaxially connected to the right end of the connecting shaft 42.

[0028] In this embodiment, the motor 43 on the support 41 can drive the connecting shaft 42 to rotate, and the connecting shaft 42 can rotate at any angle. When it rotates 90° clockwise or 90° counterclockwise, it can drive the drying drum 21 to rotate 90° clockwise or 90° counterclockwise, so that the screen 24 or screen 25 on the drying drum 21 faces downward, so as to separate the fine powder tea leaves and small pieces of tea leaves from the tea leaves.

[0029] Preferably, as another embodiment of the present invention, the drive mechanism 7 includes a mounting frame 71, a motor 72, a main gear 73 and a driven gear 74. The mounting frame 71 is provided on the top of the base plate 1, and the motor 72 is provided on the top of the mounting frame 71. The output shaft of the motor 72 and the left end of the bushing 51 are respectively provided with the main gear 73 and the driven gear 74, and the main gear 73 and the driven gear 74 mesh with each other.

[0030] In this embodiment, the motor 72 on the starting mounting bracket 71 drives the main gear 73 to rotate. The main gear 73 meshes with the driven gear 74 on the bushing 51 and transmits power to drive the bushing 51 to rotate. At the same time, the limiting cooperation between the strip-shaped opening 54 and the stirring rod 55 drives the stirring rod 55 and the horizontal shaft 52 to rotate, so as to stir the tea leaves at the same position in the drying drum 21. When the horizontal shaft 52 rotates, since the connecting block 53 and the horizontal shaft 52 are rotatably connected, the horizontal shaft 52 rotates relative to the connecting block 53.

[0031] Preferably, as another embodiment of the present invention, the reciprocating mechanism 6 includes an L-shaped frame 61, a transverse rod 62, a support frame 63, a motor 64, an active plate 65, and a driven plate 66. The top of the base plate 1 is provided with an L-shaped frame 61, and the left side of the connecting block 53 is provided with a transverse rod 62. A support frame 63 with one end connected to the outside of the L-shaped frame 61 is slidably sleeved on the transverse rod 62. The rear side of the L-shaped frame 61 is provided with an active plate 65 through which the output shaft passes. The driven plate 66 is rotatably connected between the upper end of the active plate 65 and the left end of the transverse rod 62.

[0032] In this embodiment, the motor 64 on the L-shaped frame 61 is started, and its output shaft can drive the active plate 65 to rotate. At the same time, the driven plate 66 pulls the transverse rod 62 to move laterally back and forth. During this process, the transverse rod 62 will slide on the support frame 63 and provide support for the transverse rod 62. When the transverse rod 62 moves laterally, it will drive the connecting block 53 and the transverse shaft 52 to move laterally back and forth. During this process, the transverse shaft 52 will drive the stirring rod 55 to move back and forth along the strip opening 54 to stir the tea leaves in different positions in the dry-frying drum 21, so that the tea leaves in each position are fully stirred and turned.

[0033] Preferably, as another embodiment of the present invention, the bottom of the frying drum 21 is provided with a heater 22. When the heater 22 is turned on, the heater 22 can raise the temperature of the frying drum 21, so that the tea leaves inside the frying drum 21 are heated and the moisture in the tea leaves evaporates. The top of the frying drum 21 is provided with a lid 3. The lid 3 can seal the frying drum 21 during the tea frying process to reduce heat loss. The sealed environment helps to maintain a stable temperature inside the drum, so that the tea leaves can be fried under the set temperature conditions. The lid 3 can be opened to facilitate pouring the tea leaves into the frying drum 21 for frying. After frying, the tea leaves can be poured out.

[0034] Working principle: Open the cylinder cover 3 and pour tea leaves into the drying cylinder 21. Simultaneously, start the heater 22 to raise the temperature of the drying cylinder 21. At the same time, start the motor 72 to drive the main gear 73 to rotate, allowing the main gear 73 to drive the driven gear 74 on the bushing 51 to rotate the bushing 51. Simultaneously, the limiting cooperation between the strip-shaped inlet 54 and the stirring rod 55 drives the stirring rod 55 and the horizontal shaft 52 to rotate, stirring the tea leaves at the same location in the drying cylinder 21. Simultaneously, start the motor 64 to drive the drive plate 65 to rotate, using the driven plate 66 to pull the transverse rod 62 to move laterally back and forth. During this process, the transverse rod 62 slides on the support frame 63, and simultaneously, the transverse rod 62 drives the connecting block 53 and the horizontal shaft 52 to move laterally back and forth. The horizontal shaft 52 will... The stirring rod 55 moves back and forth along the strip opening 54 to stir the tea leaves at different positions in the frying drum 21, ensuring that the tea leaves in each position are fully stirred and turned, resulting in even heating and improved tea quality. After the tea is fried, the motor 43 is started, and its output shaft drives the connecting shaft 42 to rotate. The connecting shaft 42 can rotate at any angle. When it rotates 90° clockwise or 90° counterclockwise, it can drive the frying drum 21 to rotate 90° clockwise or 90° counterclockwise, so that the screen 24 or screen 25 on the frying drum 21 faces downward, so as to separate the fine powder tea leaves and small pieces of tea leaves, improving the practicality and functionality of the equipment. When the frying drum 21 rotates 180°, the drum cover 3 is opened to pour the tea leaves out of the frying drum 21.
