Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically a tea withering device. Background Technology

[0002] Withering is a crucial step in tea processing. Its purpose is to reduce moisture in the tea leaves, causing a moderate change in the leaf's cellular structure and laying the foundation for subsequent processes such as rolling and fermentation. Currently, withering equipment is commonly used in tea processing to achieve this process. These devices typically include components to hold the tea leaves and are equipped with structures that provide hot air. The hot air accelerates the evaporation of moisture from the tea leaves, achieving the withering effect. This technology is widely used in the large-scale processing and production of various types of tea.

[0003] In the operation of existing tea processing withering equipment, most of the equipment usually blows hot air from the bottom or other positions, and the hot air delivery path is relatively fixed. The tea leaves are mostly spread on fixed support components. Since the distance between the tea leaves in different areas of the support components and the hot air outlet is different, the tea leaves closer to the hot air outlet will have priority and more contact with the hot air, and the moisture loss rate is faster; while the tea leaves farther away from the hot air outlet will have less contact with the hot air and for a later time, and the moisture loss rate is slower. Utility Model Content

[0004] The purpose of this invention is to provide a tea processing withering device to solve the problem mentioned in the background art, which is that the distance between the tea leaves in different areas of the supporting component and the hot air outlet is different, resulting in uneven moisture loss of the tea leaves in different areas.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please refer to Figures 1-4 This utility model discloses a tea processing withering device, including a base 1, with a mounting frame 11 installed on the upper rear side of the base 1. The base 1 and mounting frame 11 form an installation structure for mounting other structures. A rotating rod 12 is rotatably mounted on the top of the base 1, and multiple fan-shaped grooves 13 are provided on both sides of the rotating rod 12. Withering plates 14 are detachably installed inside the fan-shaped grooves 13, and tea leaves are spread on the withering plates 14. Withering plates 14 are placed on all the fan-shaped grooves 13 for batch withering. A PLC controller is also provided behind the mounting frame 11 for controlling all electrical equipment in the device and for pre-testing. This is a conventional technical means for those skilled in the art. The motor 3 can be a Panasonic A6 series MSMF042L1U2M, the electric telescopic rod 34 can be a TOMUUTGA-300, the hot air blower 43 can be a Ruitaifeng RTF-HB-30, and the PLC controller can be a Siemens S7-200 SMART CPU. SR20 is applicable to any model of electrical equipment and is not limited to the models listed above.

[0020] The top of the rotating rod 12 is provided with a first synchronous wheel 2, and the top of the rear of the mounting frame 11 is rotatably provided with a second synchronous wheel 21. The first synchronous wheel 2 and the second synchronous wheel 21 are meshed by a synchronous belt. When the second synchronous wheel 21 rotates, it can drive the first synchronous wheel 2 to rotate synchronously through the synchronous belt, thereby driving the rotating rod 12 and the withering plates 14 on both sides to rotate, so that the tea leaves on the withering plates 14 can receive hot air evenly and improve the withering uniformity. A slide groove 23 is provided at the rear of the mounting bracket 11. A slide frame 24 is slidably mounted inside the slide groove 23. A motor 3 is mounted on the slide frame 24. An internal hexagonal column 31 is provided on the top output end of the motor 3. A hexagonal rod 32 is slidably mounted inside the internal hexagonal column 31. A hexagonal opening 22 is provided at the bottom of the second synchronous pulley 21. The hexagonal rod 32 is installed and removed in the hexagonal opening 22. An electric telescopic rod 34 is provided at the bottom of the slide groove 23. The telescopic end of the electric telescopic rod 34 is connected to the slide frame 24. That is, the electric telescopic rod 34 pushes the slide frame 24 to slide up and down along the slide groove 23, thereby driving the motor 3, the internal hexagonal column 31 and the hexagonal rod 32 to move up and down. The lifting mechanism is as follows: when the second synchronous pulley 21 needs to be driven, the electric telescopic rod 34 extends to push the slide frame 24 upward. The electric telescopic rod 34 rises slowly, and at the same time, the motor 3 rotates slowly, so that the hexagonal rod 32 is connected and inserted into the hexagonal opening 22. At this time, the motor 3 is started, and the motor 3 can drive the second synchronous pulley 21 to rotate through the inner hexagonal column 31 and the hexagonal rod 32. When the withering is completed, the electric telescopic rod 34 shortens and pulls the slide frame 24 downward, so that the hexagonal rod 32 is disengaged from the hexagonal opening 22, realizing power separation. The operation is flexible and convenient. At this time, the operator can manually rotate the rotating rod 12 to easily remove the withering plate 14.

[0021] A spring 33 is provided on the bottom inner side of the internal hexagonal column 31. The top of the spring 33 is connected to the hexagonal rod 32. Under normal circumstances, half of the hexagonal rod 32 is in the internal hexagonal column 31 and the other half is on the outside. The spring 33 can provide elastic support for the hexagonal rod 32, avoiding hard collision when the hexagonal rod 32 is connected to the hexagonal opening 22, and protecting the integrity of the component. That is, when the hexagonal rod 32 is not connected to the hexagonal opening 22, the spring 33 retracts. When connected, the spring 33 returns to its original position, so that the hexagonal rod 32 is inserted into the hexagonal opening 22.

[0022] A hot air assembly is provided in front of the mounting frame 11. The hot air assembly includes a longitudinal pipe 4, an extension pipe 41 is provided in front of the longitudinal pipe 4, and multiple air outlets 42 are provided at the bottom of the extension pipe 41. The bottom of the withering plate 14 is a filter structure. A hot air blower 43 is provided at the bottom rear of the mounting frame 11. The air outlet of the hot air blower 43 is connected to and communicates with the longitudinal pipe 4. That is, hot air is generated by the hot air blower 43 and delivered to the extension pipe 41 through the longitudinal pipe 4. Then, the hot air is evenly blown onto the withering plate 14 below through the multiple air outlets 42 at the bottom of the extension pipe 41, thereby removing the moisture from the tea leaves.

[0023] The working principle of this utility model is as follows: First, the tea leaves to be withered are evenly spread on each withering plate 14. Then, the withering plates 14 are installed into the fan-shaped grooves 13 on both sides of the rotating rod 12. The hot air blower 43 is started, and the hot air is delivered to the extension pipe 41 through the longitudinal pipe 4. Then, the hot air is evenly blown onto the withering plates 14 below through multiple air outlets 42 at the bottom of the extension pipe 41, thereby removing the moisture from the tea leaves. At the same time, the electric telescopic rod 34 is started, which pushes the sliding frame 24 upward, causing the hexagonal rod 32 to be inserted into the hexagonal opening 22 at the bottom of the second synchronous wheel 21. Then, the motor 3 is started, and the motor 3 drives the inner hexagonal column 31 and the hexagonal rod 32 to drive the tea leaves. The second synchronous wheel 21 rotates, and the second synchronous wheel 21 drives the first synchronous wheel 2 and the rotating rod 12 to rotate through the synchronous belt. The rotating rod 12 drives the withering plates 14 on both sides to rotate synchronously. During the rotation, the tea leaves on the withering plates 14 are continuously subjected to the uniform hot air blown out of the air outlet 42. The moisture in the tea leaves in different areas is gradually removed, realizing the withering of the tea leaves. After the withering operation is completed, the motor 3 and the hot air blower 43 are turned off first, and then the electric telescopic rod 34 is controlled to shorten, so that the sliding frame 24 is lowered and the hexagonal rod 32 is disengaged from the hexagonal opening 22. At this time, the staff can manually rotate the rotating rod 12 to easily remove the withering plate 14.
