Description

Technical Field

[0001] This utility model relates to the field of fresh leaf processing technology, specifically to a high-efficiency fresh leaf withering device. Background Technology

[0002] Withering, also known as wilting, involves spreading fresh leaves evenly under certain temperature and humidity conditions to moderately promote the activity of enzymes, causing moderate physical and chemical changes in the internal substances, releasing some moisture, and causing the stems and leaves to wilt, turn dark green, and lose their grassy smell.

[0003] Traditional withering methods include sun withering, indoor natural withering, and combined withering that uses both methods. The disadvantages of traditional withering are uneven withering, long withering time, and a large degree of dependence on climate conditions. It is also labor-intensive, results in serious waste of fresh leaves, and reduces the quality and cost of tea withering. Existing tea withering machinery on the market can only blow air onto the surface of the tea leaves during ventilation, while the tea leaves piled at the bottom cannot be ventilated, thus affecting the withering effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a high-efficiency fresh leaf withering device, including a processing box 1, a rotating shaft 4 rotatably connected inside the processing box 1, an installation block 23 correspondingly installed inside the rotating shaft 4, a mesh cylinder 2 fixedly connected to the other end of the installation block 23, a positioning bolt 22 threadedly connected between the installation block 23 and the rotating shaft 4, and a baking lamp 24 installed on the upper inner side of the processing box 1. Under the action of the positioning bolt 22, the mesh cylinder 2 can be quickly installed on the rotating shaft 4, and the fresh leaves inside the mesh cylinder 2 can be baked by the baking lamp 24 above.

[0025] Gear 1 5 is fixedly connected to the outer end of the rotating shaft 4, and motor 3 is fixedly connected to the outer end of the processing box 1. Gear 2 25 is fixedly connected to the output end of motor 3. Gear 1 5 and gear 2 25 mesh with each other. An air inlet box 9 is provided at one outer end of the processing box 1, and a cover plate 21 is provided at one outer end of the mesh cylinder 2. The mesh cylinder 2 can be opened through the cover plate 21, making it easy for workers to put fresh leaves into the inside of the mesh cylinder 2. The motor drives gear 2 25 to rotate, and under the meshing action, it can drive gear 1 5 and rotating shaft 4 to rotate, completing the rotation operation of the mesh cylinder 2. With the help of the internal baking lamp 24, the leaves can tumble in the mesh cylinder 2, so that the leaves can be fully baked by the baking lamp 24.

[0026] An air inlet 14 is provided through one end of the air inlet box 9, and an air inlet pipe 8 is provided through the other end of the air inlet box 9. A heater 10 is provided through the middle of the air inlet pipe 8, and an air jet plate 6 is provided through the other end of the air inlet pipe 8 in the processing box 1. Several air jets 7 are provided above the air jet plate 6. When the air inlet element inside the air inlet box 9 is activated, the air inlet element, including an air inlet fan and a drive element, sends outside air into the heater 10 for heating. The hot air can enter the air jet plate 6 through the air inlet pipe 8, and finally spray out through the several air jets 7 at the bottom, blowing and tumbling the fresh leaves inside the mesh cylinder 2, thereby drying the leaves of the mesh cylinder 2 and further improving the wilting speed of the leaves.

[0027] The air inlet 14 is equipped with a dustproof mesh plate 15. Limiting grooves 18 are opened at both ends of the air inlet 14. Limiting blocks 16 are fixedly connected to both ends of the dustproof mesh plate 15. The outer end of the air inlet box 9 is provided with a slot 13. A spring 12 is fixedly connected to one end of the inner side of the slot 13. The other end of the spring 12 is fixedly connected to a limiting plate 20. By setting the dustproof mesh plate 15, dust and impurities in the air can be filtered and intercepted, preventing dust in the air from entering the interior of the processing box 1 and contaminating the fresh leaves.

[0028] The other end of the limiting plate 20 is fixedly connected to a positioning post 19, which is installed through the inside of the limiting groove 18. The limiting block 16 has a positioning hole 17 inside, and the positioning post 19 corresponds to the positioning hole 17. The upper end of the processing box 1 has an exhaust port 11. When the dustproof mesh plate 15 needs to be disassembled and replaced, the operator pulls the limiting plate 20 upward. Under the action of the limiting plate 20, the positioning post 19 can be moved upward. At this time, the positioning post 19 is disengaged from the inside of the positioning hole 17, and the operator can directly pull the dustproof mesh plate 15 outward to remove it, thereby completing the replacement and improving the dustproof effect of the device.

[0029] Working principle: When in use, open the cover plate 21 and place the fresh leaves inside the net cylinder 2. Then, align the mounting blocks 23 at both ends of the net cylinder 2 with the mounting grooves inside the rotating shaft 4, and lock them with positioning bolts 22 to ensure the stability of the net cylinder 2 during rotation. Next, turn on the baking lamp 24 and the motor. The motor drives the second gear 25 to rotate, which in turn drives the first gear 5 and the rotating shaft 4 to rotate, completing the rotation of the net cylinder 2. With the help of the baking lamp 24 inside, the leaves can tumble in the net cylinder 2, so that the leaves can be fully baked by the baking lamp 24. Then, start the air intake element inside the air intake box 9 to send outside air into the heater 10 for heating. The hot air can enter the air jet plate 6 through the air intake pipe 8, and finally be sprayed out through several air jets 7 at the bottom, thereby drying the leaves of the net cylinder 2, thus further improving the wilting speed of the leaves.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
