A processing method of medium and low-grade Longjing tea machine harvesting mechanism

Abstract

The invention discloses a processing method of a medium and low-grade Longjing tea machine-picking mechanism. The method includes: (1) machine-picking fresh tea leaves, using a single or double-person tea picking machine to harvest the tea trees during sunny days in spring, summer or autumn; Harvest from one bud on the crown surface to all the new shoots on the open surface; (2) spread the fresh leaves to air, place the harvested tea fresh leaves in a cool indoor silo for spreading, and spread the leaves evenly (3) deenzyming, adopting a roller deenzyming machine to deenzyme-deactivate the fresh tea leaves; (4) deenzyme cutting, adopting a cutting machine to cut the fresh leaves after deenzyming, and cut into 2-3cm tea sticks; ( 5) Microwave dehydration, use a microwave dryer to dry the cut leaves initially to remove excess water; (6) shape the green pot; (7) dry the green pot; (8) stir fry and enhance the aroma; (9) Wind selection; (10) color selection; obtain the finished product of Longjing tea. The method of the invention solves the problem of grading fresh leaves harvested by machine, unifies the specifications of Longjing tea products through cutting, and can greatly improve the production efficiency of Longjing tea.

Description

Technical field[0001]The present invention belongs to the field of tea processing, and is specifically a method of processing mechanism for medium and low-grade Longjing tea machine.Background technique[0002]Tea is one of the main economic crops in the mountainous area of ​​Zhejiang Province. It is an important source of economic sources of rural poverty reduction. Among them, Longjing Tea is the main representative of Zhejiang famous tea.[0003]Longjing Tea has a high requirements for fresh leaves. It is made by manual picking, and the machining has been completely realized. However, it is more difficult to achieve, but the machine seizing leaf mechanism is more difficult, mainly because the machine is complicated, and the machine is a buds a leaf rate. It is relatively low, and the long length of the machine is short. It is necessary to grade segmentation, and the machine is divided into difficulties, and it is very easy to red side, affecting the machining of Longjing tea machine ...

AI Technical Summary

Problems solved by technology

[0003] Longjing tea has high requirements for raw materials of fresh leaves, and picking is mainly done by hand, and mechanical processing has been fully realized, but machine-picked fresh leaf machine Longjing is difficult to realize, mainly because the composition of machine-picked leaves is complex, and the rate of one bud and one leaf is machine-picked. The proportion is relatively low, and the size and length of machine-harvested fresh leaves are different, which need to be graded and segmented for processing, while machine-harvested leaves are difficult to classify, and are prone to red edges, which affects the processing of Longjing tea machine-harvested mechanism

[0004] The existing machine-harvested processing methods of Longjing tea are generally realized according to "canopy cultivation-machine harvesting-fresh leaf grading-cleaning-green pot-hui pot". Vibration and friction caused by grading fresh leaves lead to red edges and fermented taste, affecting the quality characteristics of Longjing tea "green in color, rich in aroma, sweet in taste and beautiful in shape"
