Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically a feeding device for a drying oven used in tea processing. Background Technology

[0002] Tea is hailed as one of the world's "three major" beverages. The processing of tea leaves has an indispensable impact on their quality. The tea-making process includes picking, sun-drying, stir-frying, rolling, and drying. This process requires both manual labor and some simple mechanical devices. After rolling, due to the high moisture content of the tea leaves, they tend to stick together. If the tea is too wet, this sticking becomes even more pronounced, with some leaves clumping together. This necessitates manually breaking up the clumps before drying, a tedious process that affects processing efficiency. Furthermore, during drying, the tea leaves need to be frequently turned to ensure even heating and prevent some parts from drying too quickly while others remain damp, thus ensuring a consistent dryness across the entire batch. However, existing drying ovens use stirring rods for turning. After drying, the tea leaves are dry and brittle. The stirring rods push the leaves during stirring, causing them to come into contact with and be compressed against the oven walls, leading to breakage. In the early stages of drying, the stirred leaves also clump together, further reducing drying efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a feeding device for a drying oven for tea processing. The feeding component can disperse the tea leaves during feeding, preventing clumps of tea leaves from entering the drying mesh box. This eliminates the need for manual breaking up, improves the processing efficiency of tea leaves, and allows the tea leaves to be fed in batches, avoiding the impact of too much tea leaves at once on the drying effect. Furthermore, the turning component can turn the tea leaves during drying, ensuring that all parts of the tea leaves are heated evenly. Hot airflow blows the tea leaves upwards from the bottom of the drying mesh box, causing the tea leaves to float up and fall down, preventing the tea leaves from breaking during turning and preventing undried tea leaves from sticking together.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0005] A feeding device for a drying oven used in tea processing includes: a box body, a drying mesh box inside the box body, a feeding cylinder a at the top of the box body, the bottom end of the feeding cylinder a communicating with the inside of the drying mesh box, a raw material box outside the box body, and a feeding cylinder b fixedly connected to the top of the raw material box.

[0006] The feeding assembly is located on the outside of the box and is used to feed tea leaves into the drying mesh box. The feeding assembly includes: a mounting frame, a roller, a reducer, a conveyor belt, and a feeding plate.

[0007] A turning assembly, located inside the housing, is used to turn the tea leaves. The turning assembly includes: a blower plate, a blower outlet, a baffle, an air duct, and a diverter.

[0008] Furthermore, an L-shaped mounting frame is fixedly installed on the outside of the box near the raw material box. Three rollers are rotatably connected between the inner walls of the mounting frame on both sides. A speed reducer is fixedly installed on the outside of the mounting frame near the top. One end of the drive shaft of the speed reducer is connected to the rotation shaft of one of the rollers. A conveyor belt is connected between the three rollers. Several inclined feeding plates are fixedly connected to the outside of the conveyor belt. The feeding plates are evenly distributed at equal intervals.

[0009] Furthermore, a blowing plate is provided below the drying mesh box. The blowing plate is hollow inside. Multiple air outlets communicating with the interior of the blowing plate are opened on the top of the blowing plate. Baffles are rotatably connected between the air outlets and the inner walls on both sides. An air duct is fixedly connected to the bottom of the blowing plate. A diverter is fixedly connected to the top of the box. One end of the air duct passes through the box and is connected to the diverter.

[0010] Furthermore, the inner wall of the mounting frame near the top is rotatably connected to two opposite sides, one side of the conveyor belt is mounted on the two support rollers, the bottom of the mounting frame extends into the inside of the raw material box, and one end of the top of the mounting frame extends into the inside of the feeding cylinder a.

[0011] Furthermore, an air duct is provided inside the diverter cylinder, an air outlet a is provided on the top of the housing that communicates with the air duct, an exhaust hole is provided on the outside of the housing near the door, an air outlet b is provided on the top of the air duct, and the air duct communicates with the air outlet b.

[0012] Furthermore, a piston is provided inside the air duct, and an electric telescopic rod is fixedly installed on the top of the diverter cylinder. The bottom end of the electric telescopic rod passes through the diverter cylinder and is connected to the top of the piston.

[0013] Furthermore, the air duct has an air inlet that communicates with the outside on its side away from the periphery. The air inlet is positioned opposite to the air outlet b. A hot air blower is fixedly installed on the top of the housing, and the output end of the hot air blower is connected to the air inlet.

[0014] The beneficial effects of this utility model are:

[0015] The advantages of this invention are that the feeding component can disperse the tea leaves during feeding, preventing clumps of tea leaves from entering the drying mesh box. This eliminates the need for manual breaking up of the tea leaves, improves the processing efficiency, and allows the tea leaves to be fed in batches, avoiding the impact of pouring in too much at once on the drying effect.

[0016] Secondly, the turning component can turn the tea leaves during drying, so that all parts of the tea leaves are heated evenly. The hot airflow blows the tea leaves from the bottom of the drying mesh box upwards, causing the tea leaves to float up and fall down, thus avoiding the tea leaves from breaking during turning and the undried tea leaves from sticking together.

[0024] 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.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figures 1-6As shown, a feeding device for a drying oven used in tea processing includes: a box body 1, a drying mesh box 11 inside the box body 1, a feeding cylinder a12 at the top of the box body 1, the bottom end of the feeding cylinder a12 communicating with the inside of the drying mesh box 11, a raw material box 13 on the outside of the box body 1, and a feeding cylinder b14 fixedly connected to the top of the raw material box 13; a feeding assembly located on the outside of the box body 1 for feeding tea into the drying mesh box 11; and a turning assembly located inside the box body 1 for turning the tea.

[0028] When drying tea leaves, the kneaded tea leaves are poured into the feeding cylinder b14, and the tea leaf clumps fall into the raw material box 13. Then, the tea leaves are separated from the tea leaf clumps by the feeding component and transported to the feeding cylinder a12. The tea leaves are then transported to the drying mesh box 11 for drying. In this way, the kneaded tea leaf clumps are broken up by additional equipment, which omits this processing step. Next, the tea leaves in the drying mesh box 11 are turned over by the turning component to prevent the tea leaves from piling up and to ensure that the tea leaves are dried evenly.

[0029] Example 2

[0030] Based on Embodiment 1, the feeding assembly includes: a mounting frame 2, rollers 21, a reducer 22, a conveyor belt 23, and feeding plates 24. An L-shaped mounting frame 2 is fixedly installed on the outside of the housing 1 near the raw material box 13. Three rollers 21 are rotatably connected between the inner walls of the mounting frame 2 on opposite sides. A reducer 22 is fixedly installed on the outside of the mounting frame 2 near the top. One end of the drive shaft of the reducer 22 is connected to the rotation shaft of one of the rollers 21. A conveyor belt 23 is connected between the three rollers 21. Several feeding plates 24 are fixedly connected to the outside of the conveyor belt 23 and are arranged at an incline. The feeding plates 24 are evenly distributed at equal intervals. Support rollers 25 are rotatably connected to the inner walls of the mounting frame 2 near the top on opposite sides. One side of the conveyor belt 23 rests on two support rollers 25. The bottom of the mounting frame 2 extends into the inside of the raw material box 13, and one end of the top of the mounting frame 2 extends into the inside of the feeding cylinder a12.

[0031] After being kneaded, the tea leaves enter the raw material box 13. The inclined platform inside the raw material box 13 causes the tea leaves to come into contact with the conveyor belt 23. Then, the reducer 22 is started, which drives the connected roller 21 to rotate instantaneously, thereby driving the conveyor belt 23 to move. The three rollers 21 and the two support rollers 25 can change the shape of the conveyor belt 23 to make it into an L-shaped structure and limit the movement trajectory of the feeding plate 24. The movement of the conveyor belt 23 drives the feeding plate 24 to move. The feeding plate 24 comes into contact with the tea leaves. When the feeding plate 24 moves, it scrapes off a portion of the tea leaves from the tea leaves. The inclined feeding plate 24 can block and lift this scraped tea leaves upward. Since the diameter of the tea leaves is larger than the length of the feeding plate 24, some small tea leaves will not be lifted. The separated tea leaves are transported to the drying mesh box 11 by the conveyor belt 23 for drying.

[0032] Example 3

[0033] Based on Embodiment 1, the material turning assembly includes: a blowing plate 3, blowing ports 31, baffles 32, air ducts 33, and a diverter cylinder 34. A blowing plate 3 is located below the drying mesh box 11. The blowing plate 3 is hollow inside. Multiple blowing ports 31 communicating with the interior of the blowing plate 3 are opened at the top of the blowing plate 3. Baffles 32 are rotatably connected between the inner walls of the blowing ports 31 on opposite sides. An air duct 33 is fixedly connected to the bottom of the blowing plate 3. A diverter cylinder 34 is fixedly connected to the top of the box 1. One end of the air duct 33 passes through the box 1 and connects to the diverter cylinder 34. An air channel 35 is opened inside the diverter cylinder 34. An opening at the top of the box 1 communicates with the air channel 35. The air outlet a36 is provided. An exhaust hole 37 is provided on the side of the box body 1 near the door. An air outlet b38 is provided on the top of the air duct 35. The air pipe 33 is connected to the air outlet b38. A piston 39 is provided inside the air duct 35. An electric telescopic rod 310 is fixedly installed on the top of the diverter cylinder 34. The bottom end of the electric telescopic rod 310 passes through the diverter cylinder 34 and is connected to the top of the piston 39. An air inlet 311 is provided on the side of the air duct 35 away from the periphery and is connected to the outside. The air inlet 311 is opposite to the air outlet b38. A hot air blower 312 is fixedly installed on the top of the box body 1. The output end of the hot air blower 312 is connected to the air inlet 311.

[0034] During drying, the air inlet 311 and air outlet a36 are connected. Then, the hot air blower 312 is activated, generating hot air that enters the chamber 1 through the air outlet a36, raising the temperature inside the chamber 1 and causing the moisture in the tea leaves inside the drying mesh box 11 to evaporate quickly, thus drying the tea. Some of the hot air is discharged through the exhaust port 37, forming a circulation and preventing excessive pressure inside the chamber 1. When it is necessary to turn the tea leaves inside the drying mesh box 11, the electric telescopic rod 310 is activated, pushing the rod downwards. The piston 39 is pushed to its limit along the air duct 35. At this time, the air inlet 311 and the air outlet b38 are connected. The hot air enters the interior of the blower plate 3 through the air pipe 33 and is then blown out from the air outlet 31 at the top of the blower plate 3. The blown air has a large impact force, which pushes open the baffle 32. The blown air enters the interior from the bottom of the drying mesh box 11, which blows up the tea leaves that have fallen to the bottom of the drying mesh box 11. Under the action of the upward airflow, the tea leaves are turned over, so as to make the drying more uniform and improve the product quality.
