Embodiment Construction

[0032] The raw materials of summer and autumn tea leaves in the Jiangbei tea area are characterized by: (1) long internodes; (2) large difference in size between the second leaf and the first leaf.

[0033] A method for processing fresh glycol type summer and autumn green tea from Jiangbei tea area, the steps are as follows:

[0034] 1. Standards for fresh leaves: picking new shoots or a single young leaf (second leaf) with 1 bud and 1 leaf in summer and autumn, and picking diseased and insect leaves, rain leaves, and dew leaves are prohibited; fresh leaves are packed in ventilated baskets and transported to the processing plant , during which to avoid mechanical damage and heap boredom.

[0035] 2. Long stand and short vibration: put the fresh leaves in air-drying / withering equipment (such as existing silage machine, lift-type drying / withering equipment) or utensils (such as: existing bamboo trays for spreading tea leaves) , the thickness of the spreading leaves is based on ...

Abstract

The present invention relates to a processing method of fresh-and-mellow type and sweet-and-mellow type summer-autumn green tea in tea area north of Yangtze River. A current raw material of "one bud and two leaves" is replaced by two raw materials of "one bud and one leaf" and "single leaf"; a cycle alternation of "long-time spreading for 3-4 h + short-time vibrating for 1-3 min is conducted for 2-3 times; finally, after the vibrating, then the spreading is conducted for 4-6 h; fresh leaves are spread for a total time reaching 10-16 hours to prepare the green tea. The method can realize the processing of the two raw materials to respectively obtain the fresh-and-mellow type green tea and sweet-and-mellow type green tea. A multifunctional strip-tidying machine combines processes of enzyme-deactivating and primary shaping processes; traditional methods of past roller enzyme deactivating and rolling and shaping by a rolling machine are changed; a problem that the color and luster of the summer-autumn green tea are deep and dark is avoided; and the processing method also reduces a breakage rate of tea leaf cells and can effectively solve problems that summer fresh leaves are long in internodes and adjacent blade shapes are large in differences, leading to poor shape uniformity of the product.

Description

technical field [0001] The invention relates to a processing method of fresh sweet-mellow summer-autumn green tea in the Jiangbei tea region, especially the new shoots or single leaves of tea trees with one bud and one leaf in summer and autumn in the Jiangbei tea region as raw materials, and the product has "fresh alcohol" or "glycol" High-quality green tea processing method characterized by taste quality.
