Description

Automatic grading equipment for fresh tea leaves
Technical Field
The invention relates to the technical field of black tea processing equipment, in particular to automatic grading equipment for fresh tea.
Background
The black tea belongs to black tea, the more old the black tea is, the better the taste is, and the stronger the functionality is, the view is accepted by most tea people, and the alone products with historical value are more noble than gold. The dark green tea is prepared by processing large-leaf tea planted in an inhomogenous mountain area through the processes of enzyme deactivation, rolling, pile fermentation, baking, drying and the like, and is refined by taking the dark green tea as a raw material (comprising artificial post-fermentation and natural aging). The dark tea is mainly divided into four grades, namely first-grade dark green tea: one bud and three leaves are initially developed. Second-stage raw dark green tea: one bud with three leaves and one bud with four leaves for initial expansion. Third-stage raw dark green tea: one bud, five leaves and six leaves. (sprout-standing and mature young sprout) -fourth-grade dark green tea: mature shoot is the main. (Red stalks, lignified shoots).
Tea classification in the current market is mostly arranged to be carried out after drying, and can be divided into manual or mechanical sorting, so that the manual classification efficiency is low, the labor amount is large, the tea classification can be caused by the classification of the dry tea machine, a large amount of broken powder is generated, and unnecessary waste is caused. Therefore, the design of an integrated automatic device for grading fresh tea and cutting stalks is considered. The quality of the fresh dark tea leaves is the basis of post processing, the screening equipment of the fresh dark tea leaves in China at present mainly uses a tapered bamboo drum-type screening machine, the equipment uses bamboo splits as materials to weave a drum full of screening holes, and the grading purpose can be realized when the fresh dark tea leaves roll in the drum. The method (see patent 201710962511.5) is convenient to operate and low in cost, but screen holes on a screen cylinder are often partially blocked by fresh leaves in the using process, and for black tea type fresh tea with rough and old branches and leaves, the tea grading is mainly reflected in that the difference in length is more obvious, and the drum-type screening machine has the condition that the tea is not easy to leak and the grading is inaccurate.
