Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a tea air sorting machine. Background Art

[0002] The purpose of air separation is to utilize the differences in weight, volume, shape and windshield size between tender tea leaves and light impurities, sand and gravel and other non-tea inclusions, and to separate the light yellow flakes, sand and gravel and other non-tea inclusions in the tea leaves under a certain wind force, so as to achieve the purpose of purifying the tea leaves.

[0003] In the prior art, a Chinese patent with publication number CN219836816U discloses a tea air-selecting machine, which adopts the scheme of "comprising a shell, a feeding port being provided at the upper end of the shell; a fan being fixedly mounted on the side wall of the shell, a conveying pipe being fixedly mounted on the output end of the fan, a blow hood being fixedly mounted on the inner side of the shell, and an end of the conveying pipe away from the fan being connected to the blow hood; a second screen being vertically fixedly mounted on the inner side of the shell, and a first screen being fixedly mounted on the inner side of the shell". This scheme can prevent dust from falling everywhere by performing the air-selection work inside the shell, so as to facilitate the centralized treatment of dust, will not affect the working environment of the staff, and effectively protect the health of the staff.

[0004] However, the above scheme still has some shortcomings. For example, in actual use, the above scheme can only filter the dust mixed in the tea leaves by air separation, but lacks a mechanism to screen out debris such as gravel and large mud and sand particles, resulting in the gravel and debris falling into the tea collection box in the scheme together with the tea leaves. The air separation effect is not ideal and affects the subsequent product quality of the tea. In view of this, the utility model proposes a tea air separation machine. Utility Model Content
