Problems solved by technology

[0002] With the development of the national economy, the transfer of labor force to industry and towns is accelerating. The shortage of tea picking labor and the increase in cost have affected the sustainable and healthy development of the tea industry. The mechanized picking and subsequent processing of fresh leaves is an inevitable trend. Machine-picked fresh tea leaves Subsequent processing has always been a difficult point in the industry, mainly because the existing tea-picking machinery can only reciprocate and cut the new shoots of tea trees indiscriminately, resulting in large differences in the specifications of machine-picked fresh tea leaves, uneven defects, and old and tender leaves. The first-class problems lead to different subsequent processing techniques, unstable product quality, and insufficient economic benefits.

Embodiment 1

[0033] according to him Figure 1-Figure 5 Shown, a kind of tea sorting method comprises the following steps:

[0034] First, divide the grade of tea: according to the size and appearance of the leaf stem, fresh tea is divided into thick leaf stem, one bud with four leaves, one bud with three leaves, one bud with two leaves, one bud with one leaf, and finely crushed tea according to the size and appearance of the leaf stem. The six grades of leaves and stems;

[0035] Second, set the number of sorting levels: set five graded monomers A for the above six grades, which are the first graded monomer A1, the second graded monomer A2, the third graded monomer A3, and the fourth graded monomer Body A4, the fifth grading monomer A5, wherein, the first grading monomer A1 completes the separation of the thick leaf stem from the one-bud four-leaf and the following size grades, and the second grading monomer A2 completes the one-bud four-leaf and Separation of one bud with three leaves ...

Abstract

The invention relates to the field of tea production, in particular to a tea sorting method. The tea sorting method comprises the following steps that the first step, tea grade is divided, and fresh tea is divided into six grades from large to small according to leaf stem size condition; the second step, sorting grade is arranged, and five grading single bodies are arranged for the six grades; thethird step, the structure of the grading monomers is structured, and each grading monomer comprises a lifting component, an air suspending component, a flexible net belt sorting component and an output component; the fourth step, the screening net size is set; the fifth step, grading screening is performed. According to the tea sorting method, a multistage screening method is adopted, classifiedoutput can be performed on tea according to various different methods, and coarse leaves and fine leaves are output separately, the mixed degree is low, an air suspending method is adopted, leaves aremade to be low in speed when reaching a flexible net belt and are almost in static, so that damage to the tea in the screening process is reduced, the air suspending angles are adjustable, and the tea sorting method can adapt to the tea of different kinds.
