Description

Technical field:

[0001] The utility model relates to a wind selection device for preparing characteristic rock tea. Background technology:

[0002] Rock tea leaves are in the form of strips, and a large amount of tea dust is easily produced during the later drying and picking process. The presence of tea dust reduces the appearance of the tea after packaging and reduces the value of the tea. Therefore, before packaging the tea, it is often necessary to remove the tea dust to obtain tea with better appearance and then package it. Relying on the traditional manual screening method is inefficient and does not meet the needs of modern production. For this reason, many tea wind selection equipment have emerged to replace traditional manual screening, such as the tea wind selection device disclosed in Chinese Patent Publication No. CN213255729U, but the tea wind selection device consists of a conveying device, a wind selection device and a vibration device, and the overall structure is relatively complex, which increases the equipment cost; at the same time, although the wind selection effect is improved by two screenings, the corresponding wind selection takes a long time, which in turn affects the wind selection efficiency. Utility model content:

[0003] The utility model makes improvements on the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the utility model is to provide a wind selection device for preparing characteristic rock tea, which is not only simple and reasonable in structure, but also improves the wind selection efficiency.
