Description

Technical Field

[0001] The utility model relates to the technical field of raw tea processing, in particular to a multiple screening device for raw tea processing. Background Art

[0002] Maocha is also called Maotiao. The product after the fresh leaves are processed is called Maocha. Its quality characteristics have been basically formed and it can be drunk. In addition, the raw materials of clear tea, black tea and green tea are also called Maocha, which are called black Maocha, green Maocha and Qing Maocha. Maocha needs to be screened in advance because it is mixed with many impurities such as broken pieces during the processing. However, with the continuous increase in market demand for tea processing, there are still some deficiencies in the actual use of the screening device for Maocha, which needs to be improved.

[0003] Currently, most of the common raw tea screening devices on the market have the problems of simple structure and rough screening method. They are unable to flexibly adjust the screening accuracy of the raw tea according to actual screening needs, which greatly reduces the screening effect of the raw tea. At the same time, the raw tea screening process relies too much on mechanical methods such as vibration to separate tea powder, etc. However, such screening operations will not only invisibly increase the generation of tea powder, but also have low screening efficiency.

[0004] In the patent document with the publication number CN218531802U, a raw tea screening and sorting device is proposed, which includes a box body, the box body is rotatably connected with an outer cylinder, the outer side of the outer cylinder is rotatably connected with the box body through an air supply pipe, the inner side of the outer cylinder is slidably connected with an inner cylinder through an adjustment component, the inner side of the inner cylinder is provided with a flip plate, the box body, the outer cylinder and the inner cylinder are all detachably connected with a cover plate, the cover plate is rotatably connected with the adjustment component, and the cover plate is equipped with a waste material port. The utility model can flexibly adjust the screening accuracy of the device and change the screening effect of the device on raw tea by setting a slidingly connected inner cylinder; by setting an air supply pipe, the air flow inside the air supply pipe drives the outer cylinder and the box body to rotate, and at the same time, the through hole on the top of the box body is cleaned to avoid some tea leaves blocking the through hole, and when passing through the waste material port, the broken pieces and dust adhering to the tea leaves are brought to the outside of the box body, which can improve the screening effect of the device on tea leaves.
