Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea withering rack technology, and in particular to an intelligent tea drying and withering rack. Background Technology
[0002] Withering is a crucial step in tea processing. It refers to the gradual loss of moisture from freshly picked tea leaves under specific environmental conditions, undergoing a series of physical and chemical changes to develop their unique aroma and flavor. This process involves spreading the tea leaves evenly and allowing them to wilt in the sun. This promotes the activity of enzymes within the tea leaves, causing moderate physical and chemical changes in their components, releasing some moisture, and resulting in wilted stems and leaves with a darker green color, while also eliminating any grassy aroma. The primary purpose of withering is to reduce moisture in the tea leaves, decrease enzyme activity, and thus prevent the enzymatic oxidation of tea polyphenols, maintaining the bright green color of the leaves. Furthermore, withering helps remove any unpleasant odors from the tea leaves, allowing their aroma and flavor to develop.
[0003] Traditional withering racks are typically upright frames where tea leaves are placed in sieve frames, which are then stacked on the upright frame. However, these racks cannot turn the tea leaves over during use, resulting in a noticeable withering effect for the surface tea leaves and a poorer withering effect for the inner tea leaves. Therefore, workers need to manually vibrate and turn the tea leaves in the sieve frames multiple times, which is inconvenient for practical use.

After the drying frame 4 moves into place, the locking hole 43 and the positioning hole 34 are aligned. Release the handle 38, and the locking rod 35 is inserted into the locking hole 43 to lock the drying frame 4 and prevent it from shaking.
[0044] 2) After all the drying frames 4 are placed, start the electric push rod 9. The electric push rod 9 extends and drives the height adjustment frame 3, thereby causing the lever 73 to be inserted into the drying frame 4. Start the motor 22. With the cooperation of the rotating shaft 23, the driving pulley 24, the belt, the driven pulley 62 and the connecting shaft 6, the motor 22 synchronously drives multiple flipping shafts 7, flipping rods 72 and levers 73 to rotate, thereby synchronously flipping the tea leaves inside the multiple drying frames 4.
[0045] 3) After drying, start the electric push rod 9. The electric push rod 9 retracts, the drying frame 4 descends and disengages from the lever 73. Pull down the handle 38, the locking rod 35 moves out of the locking hole 43, and the locking of the drying frame 4 is released. The drying frame 4 can then be pulled out to collect the tea leaves.
[0046] Compared with the prior art, the present invention has the following advantages:
[0047] In this invention, the motor 22, in conjunction with the rotating shaft 23, the driving pulley 24, the belt, the driven pulley 62, and the connecting shaft 6, synchronously drives multiple flipping shafts 7, flipping rods 72, and levers 73 to rotate, thereby synchronously turning the tea leaves inside multiple drying frames 4. This helps to turn the tea leaves over without requiring manual turning, saving manpower. The staggered levers 73 further enhance the turning effect and prevent the tea leaves located between the levers 73 from not being effectively turned, ensuring the practicality of the device.
