Description

Technical Field

[0001] The utility model relates to the technical field of tea leaf withering, in particular to a tea leaf withering pretreatment device for tea leaf processing. Background Art

[0002] Tea withering refers to the process of treating fresh leaves with high temperatures to quickly destroy the activity of enzymes in the leaves and stop the enzymatic oxidation of polyphenols to keep the leaves green. At the same time, it releases some moisture to soften the leaves, making them easier to process in subsequent rolling and other processes. This process plays a vital role in the final quality of tea.

[0003] According to a Chinese patent with the publication number "CN216088643U", a tea leaf withering pretreatment device for tea processing includes a withering box, a heating plate is arranged on the surface of the withering box, a second motor is arranged on the top of the withering box, a second rotating shaft is arranged at the output end of the second motor, arc-shaped connecting rods are arranged on the surface of the second rotating shaft, a connecting plate is arranged at one end of the arc-shaped connecting rod, and connecting columns are arranged on one side and both ends of the connecting plate. Before withering the tea leaves, water is transported to the inside of the connecting pipe through an external water pipe, and then sprayed out by a nozzle to rinse the inside of the equipment. The inside of the equipment is rinsed clean to avoid impurities on the inner wall, which may affect the withering effect. When cleaning, the wiping plate is rotated to rotate and rub on the inner wall of the withering box, so that the wiping plate cleans the inner wall, thereby increasing the cleaning performance and improving the cleanliness. When the above-mentioned device is in use, no conveying mechanism is set, which is not convenient for uniformly conveying the tea leaves. When the tea leaves are placed in the withering box, the tea leaves are prone to clumping inside, thereby reducing the subsequent tea withering efficiency. Therefore, a withering pretreatment device for tea processing is proposed to solve the above-mentioned problems. Utility Model Content
