Description

Technical Field

[0001] This utility model relates to the technical field of drying devices for tea processing, specifically a drying device for tea processing with a sieving function. Background Technology

[0002] Tea drying equipment is a key piece of equipment in the later drying stage of tea processing. Its core function is to remove moisture from tea leaves through heat exchange while retaining nutrients such as theanine and aroma components. This equipment is environmentally friendly, energy-saving, and easy to operate, making it widely applicable to the production of premium teas, especially suitable for small processing plants or home use. It can use inexpensive firewood or ordinary coal as fuel, resulting in low energy costs. Furthermore, the tea leaves do not directly contact the heat source during the drying process; uniform drying is achieved through hot air circulation.

[0003] Traditional tea drying equipment typically uses static spreading or simple turning methods, which can easily lead to tea piling up, uneven heating, and even clumping, affecting drying efficiency and product quality. Utility Model Content

[0004] The purpose of this utility model is to provide a tea drying device with a screening function, which solves the problem that traditional tea drying equipment usually adopts static spreading or simple turning, which easily leads to tea accumulation, uneven heating, and even clumping, affecting drying efficiency and finished product quality.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a drying device for tea processing with sieving function, including a drying box, a door panel hinged to the front of the drying box, a drying mechanism fixedly installed on one side of the drying box, the output end of the drying mechanism being connected to the inside of the drying box, a sieving mechanism installed inside the drying box, and a picking mechanism installed inside the drying box, with the picking mechanism's picking end located inside the feeding end of the sieving mechanism.

[0007] Furthermore, the stirring mechanism includes a first electric push rod, which is fixedly installed on the upper surface of the drying chamber. The output end of the first electric push rod extends into the interior of the drying chamber. An extension rod is fixedly installed on the output end of the first electric push rod. A mounting frame is fixedly installed on one end of the extension rod. Several rotating rods are rotatably connected to the inner wall of the mounting frame. Several first stirring rods are fixedly installed on the outer surface of each rotating rod. Several second stirring rods are fixedly installed on the outer surface of each first stirring rod. A half gear is fixedly installed on one end of each rotating rod.

[0008] Furthermore, a second electric push rod is fixedly mounted on the outer surface of the mounting bracket, a fixing plate is fixedly mounted on the output end of the second electric push rod, and a rack is fixedly mounted on the lower surface of one end of the fixing plate, the rack being meshed with several half gears.

[0009] Furthermore, the screening mechanism includes mounting plates, the number of which is fixed to four sets, and the number of mounting plates in each set is fixed to two. The mounting plates are fixedly installed on the inner surface of the drying chamber, and a limiting slide rod is fixedly installed between every two mounting plates. The drying chamber is provided with a receiving box inside, and the inside of the receiving box is slidably connected to the outer surface of the limiting slide rod.

[0010] Furthermore, springs are fitted onto the outer surface of each limiting slide rod, and one end of each spring abuts against the outer surface of the receiving box.

[0011] Furthermore, a vibration motor is fixedly installed on the outer surface of the container, and a screening box is placed inside the container.

[0012] Furthermore, the rotating rod, the first picking rod, and the second picking rod are all located inside the screening box.

[0013] This utility model has the following beneficial effects:

[0014] (1) The first electric push rod of this utility model is activated, which drives the extension rod and the mounting frame to move downward, so that the rotating rod, the first picking rod and the second picking rod enter the screening box. At this time, the second electric push rod drives the fixed plate to move along the rack and pinion, and the rotating rod is rotated by the meshing half gear. Thus, the tea leaves are turned over, dispersed and evenly spread by the multi-stage picking rod, so as to ensure that the material is fully in contact with the hot air and avoid caking.

[0015] (2) This utility model drives the multi-layer stirring component through an electric push rod and rack and pinion transmission system to realize three-dimensional stirring of materials, thus solving the problem of easy clogging of traditional static screens.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A mounting bracket 503 is fixedly installed at one end of the extension rod 502. Several rotating rods 504 are rotatably connected to the inner wall of the mounting bracket 503. Several first picking rods 505 are fixedly installed on the outer surface of each rotating rod 504. Several second picking rods 506 are fixedly installed on the outer surface of each first picking rod 505. A half gear 507 is fixedly installed at one end of each rotating rod 504.

[0028] A second electric push rod 508 is fixedly installed on the outer surface of the mounting bracket 503. A fixing plate 509 is fixedly installed on the output end of the second electric push rod 508. A rack 510 is fixedly installed on the lower surface of one end of the fixing plate 509. The rack 510 is meshed with several half gears 507.

[0029] The first electric push rod 501 is activated, which drives the extension rod 502 and the mounting bracket 503 to move downward, so that the rotating rod 504, the first picking rod 505 and the second picking rod 506 enter the screening box 406. At this time, the second electric push rod 508 drives the fixed plate 509 to move along the rack 510, and the rotating rod is rotated through the meshing half gear 507. Thus, the tea leaves are turned over, dispersed and evenly spread by the multi-stage picking rods, so as to ensure that the material is fully in contact with the hot air and avoid caking.

[0030] The screening mechanism 4 includes a mounting plate 401. The number of mounting plates 401 is fixed to four sets, and the number of mounting plates 401 in each set is fixed to two. The mounting plates 401 are fixedly installed on the inner surface of the drying box 1. A limiting slide rod 402 is fixedly installed between every two mounting plates 401. The drying box 1 is provided with a receiving box 403. The inside of the receiving box 403 is slidably connected to the outer surface of the limiting slide rod 402.

[0031] Springs 404 are sleeved on the outer surface of the limiting slide bar 402, and one end of each spring 404 abuts against the outer surface of the receiving box 403.

[0032] A vibration motor 405 is fixedly installed on the outer surface of the container 403, and a screening box 406 is placed inside the container 403.

[0033] During the sorting process, the vibration motor 405 is started, and the limiting slide bar 402 works with the spring 404 to achieve flexible support, allowing the container to sway slightly with the high-frequency vibration generated by the vibration motor 405, which can then vibrate and sieve the tea leaves.

[0034] The rotating rod 504, the first lifting rod 505, and the second lifting rod 506 are all located inside the screening box 406.

[0035] When using it, first place the tea leaves that need to be dried inside the sieving box 406, then start the drying mechanism 3, and the drying mechanism 3 sends a constant temperature airflow into the box.

[0036] Simultaneously, the first electric push rod 501 is activated, driving the extension rod 502 and the mounting bracket 503 to move downwards, so that the rotating rod 504, the first picking rod 505 and the second picking rod 506 enter the screening box 406. At this time, the second electric push rod 508 drives the fixed plate 509 to move along the rack 510, and through the meshing half gear 507, it causes the rotating rod to rotate, thereby using the multi-stage picking rods to turn, disperse and evenly spread the tea leaves, so as to ensure that the material is fully in contact with the hot air and avoid clumping.

[0037] During the sorting process, the vibration motor 405 is started, and the limiting slide bar 402 works with the spring 404 to achieve flexible support, allowing the container to sway slightly with the high-frequency vibration generated by the vibration motor 405, which can then vibrate and sieve the tea leaves.

[0038] At the same time, the drying mechanism 3 is activated to continuously blow constant temperature airflow into the chamber, completing the drying and sieving processes simultaneously.
