Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, and particularly relates to a pre-treatment device for tea killing in tea processing. Background Technique

[0002] Tea refers to the leaves and buds of tea trees, with aliases such as tea, jia, ming, and chuan. It generally refers to the leaves of evergreen shrub tea trees that can be used for making tea, as well as the beverages brewed with these leaves. Later, it was extended to all herbal teas brewed with plant flowers, leaves, seeds, and roots. Tea killing is a tea-making step that destroys and inactivates the oxidation enzyme activity in fresh tea leaves through high temperature, inhibits the enzymatic oxidation of tea polyphenols and the like in fresh leaves, evaporates part of the water in fresh leaves, makes the tea leaves soft, facilitates rolling into shape, and at the same time emits a green smell and promotes the formation of good aroma. Before tea killing, it is also necessary to clean and dry the picked tea leaves.

[0003] After retrieval, in the prior art, a Chinese patent with the patent application number CN202221986223.6 discloses a pre-treatment device for tea killing in tea processing, including a bottom plate. One side of the top of the bottom plate is fixedly connected with a first support. The top of one side of the first support is fixedly connected with two motor brackets. A driving motor is fixedly connected between the two motor brackets. The output end of the driving motor is fixedly connected with a first fixing plate. The other side of the top of the bottom plate is fixedly connected with a second support. A rotating shaft is rotatably connected to the position close to the center of the top of the second support. Two limit bolts are rotatably connected to the position close to the top of the second support. A corresponding limit sleeve is rotatably connected to one side of each of the two limit bolts. This utility model designs a cleaning mechanism driven by a motor to clean the tea leaves inside through a rotating box body, greatly saving manpower and not causing damage to the tea leaves. At the same time, it is convenient to discharge the tea leaves after cleaning. After cleaning, they fall into the drying box, and the next drying work can be carried out quickly, saving time and effort. However, there are still the following defects:

[0004] (1) In the prior art, the pre-treatment device for tea killing performs single-time cleaning pre-treatment on tea leaves, resulting in poor cleanliness of the tea leaf cleaning pre-treatment and reducing the pre-treatment effect.

[0005] (2) In the prior art, after the pre-treatment device for tea killing pre-treats the tea leaves by cleaning, it is inconvenient to effectively drain the water in the tea leaves, resulting in a longer drying time. At the same time, it is also necessary to manually open the bucket lid to pour the materials, and the operation is relatively cumbersome.
