Method for processing Tianmu cloud and mist tea leaves

Abstract

The invention discloses a method for processing Tianmu cloud and mist tea leaves, relates to the field of tea leaf manufacture, and particularly relates to methods for processing Tianmu cloud and mist tea leaves. The method includes steps that fresh leaves are spread, to be more specific, the fresh leaves are uniformly spread on pads with thin bamboo strips or flat round split-bamboo baskets, the pads with the thin bamboo strips or the flat round split-bamboo baskets are arranged at cool and ventilated locations, the spreading thicknesses of the fresh leaves are dependent on the levels of the fresh leaves, bud leaves of the top-valley level fresh leaves and the grain-rain-prior level fresh leaves cannot overlapped on one another, the spreading thicknesses of the Meijian level and Meibai level fresh leaves cannot be larger than 2 cm, the spreading thicknesses of the Xiaoqing level fresh leaves cannot be larger than 3cm, the fresh leaves are spread for the spreading time of 6-8 h and are gently turned over by 1-2 times in the spreading period, workers need to gather the fresh leaves by means of shaking the pads with the thin bamboo strips or the flat round split-bamboo baskets when the fresh leaves are about to be turned over, and then uniformly spread the leaves, and the fresh leaves stop from being spread when reaching such spreading degrees that the moisture content of the fresh leaves is 70% approximately, the weights of the fresh leaves are reduced by 12%-14%, the bud leaves are softened and faint scent appears; enzyme deactivating and water removing are carried out, to be more specific, enzyme deactivating and water removing are carried out on the fresh leaves by the aid of model-30 or model-40 cylinder enzyme deactivating and water removing machines at the high temperatures for the enzyme deactivating and water removing time of 1-1.2 min in each enzyme deactivating and water removing procedure, and the leaf input quantities are 15 kg / h. The method has the advantages that the method is easy to implement, and the Tianmu cloud and mist tea leaves are convenient to process; the processing quality of products and the processing efficiency can be improved, and the production cost can be saved.

Description

Technical field [0001] The present invention relates to the field of tea making, in particular to a method for processing Tianmu Qingding tea leaves. Background technique [0002] Tianmu Qingding is produced in the Tianmu mountainous area of ​​Lin'an, Zhejiang Province. It has been made by hand for a long time, with low work efficiency and unstable quality. Tianmu Qingding is a roasted green tea, divided into 5 grades, followed by Dinggu, Yuqian, Meijian, Meibai and Xiaoqing. The corresponding fresh leaf standards for the various grades of Tianmu Qingding are: top valley grade: one leaf wraps up buds; pre-yu grade: one bud and one leaf develops, the bud is longer than the leaf, and the length of the bud is about 2.5cm; the plum tip grade: one bud and one leaf Two leaves are beginning to unfold, buds and leaves are roughly flat, buds and leaves are about 3cm in length; plum white grade: one bud and two leaves, buds are shorter than leaves, buds are about 3cm in length; small gree...
