Problems solved by technology

However, there are not many reports on the classification and processing of fresh leaves after classification. The existing literature is mainly on the classification and processing of bulk tea, and there is no report on the classification and processing of machine-picked green tea leaves.

Embodiment 1

[0032] see figure 1 , a kind of machine adopts the method for fresh leaf processing curly type green tea, realizes through the following steps:

[0033] 1. Picking fresh leaves: 405kg of fresh leaves of Fuding Dabai variety were picked by SV100 tea picking machine produced by Kawasaki Company;

[0034] 2. Classification of machine-picked leaves: YJY-2 fresh leaf classifier produced by Yuyao Yao Jiangyuan Tea Machine Co., Ltd. is used to classify machine-picked fresh leaves. The sieve configuration of the three-stage sieve plate of the fresh leaf classifier is: ellipse Hole sieve plate (a=1.8cm, b=2.2cm) + round hole sieve plate (D=2.0cm) + round hole sieve plate (D=2.6cm); obtain 7kg of fresh leaves from the first leaf outlet 1 by grading , 25kg of fresh leaves at the second leaf outlet 2, 120kg of fresh leaves at the third leaf outlet 3, and 253kg of fresh leaves at the fourth leaf outlet 4. Certainly.

[0035] 3. After mixing the fresh leaves of the second leaf outlet 2 ...

Embodiment 2

[0055] Embodiment 2 The quality comparison of curly type green tea made by adopting the method of the present invention and the curly type green tea made by traditional hand-picked fresh leaves

[0056]

[0057] It can be seen from Table 1 that compared with hand sampling, graded tea sample 1 is relatively similar in appearance and internal quality after machine-picked leaves and graded products, while graded tea sample 2 is slightly inferior in tenderness due to the main fresh leaves , there are gaps in quality scores such as appearance and leaf bottom, but there are small differences in internal qualities such as aroma and taste, which will have a better market prospect.

Abstract

The invention provides a method for processing fresh tea leaves picked by a machine into curly green teas. The method comprises the following steps: performing grading operation on fresh tea leaves picked by a machine through fresh tea leaf grading equipment, performing classification treatment on graded fresh leaves obtained from different leaf outlets according to the quality features of the curly green teas and fresh leaf requirements, and making the curly green teas by adopting a specific technology technique in accordance with the quality and the feature of classified fresh leaves. The method disclosed by the invention breaks through the technical bottleneck that only popular teas can be picked and made by the machine, and famous green teas cannot be picked and made by the machine; firstly the grading operation is performed on the tea leaves picked by the machine through a fresh leaf grading machine, the tea leaves are graded through sieve plates with specific sieve pores according to the characteristics of fresh leaf raw materials and the technology of the curly tea so that the requirements of the raw materials of the curly tea are met; then the graded tea leaves are classified and treated, then different grades of curly green teas are made through innovation on a processing technology, and different grades of the curly green tea products are obtained. The method disclosed by the invention is reasonable in design, and can be applied to process the fresh tea leaves into the curly green teas.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and relates to the sorting and processing of machine-picked fresh leaves, in particular to a method for machine-picked fresh leaves to process curly green tea. Background technique [0002] In recent years, under the dual guidance of national policy constraints and consumer market promotion, high-quality tea with the characteristics of good quality, high cost performance and wide consumption fields has gradually become the main body of the tea product market. At present, the picking and grading of high-quality green tea fresh leaf raw materials have encountered a key technical bottleneck. As far as picking is concerned, with the intensification of the shortage of tea pickers, labor costs continue to rise, and labor costs account for 60%-80% of the total production cost. , and the distinguishable intelligent picking machine is still in the laboratory stage, and the reciprocating cutting pic...
