Abstract

The invention discloses a withering method for tea leaves. The method comprises the following steps: natural withering: laying picked fresh and tender tea leaves on a withering frame for withering, and turning over for one time every 20 min; freezing treatment: sending the laid tea leaves to a freezing room for freezing; hot-air withering: while turning over, spraying a sodium chloride solution ofwhich concentration is 10-15% to the frozen tea leaves, after spraying, laying the tea leaves in a ventilating room and blowing in hot-air for withering; final withering: taking out the tea leaves inthe ventilating room and placing in a withering tank for withering. Compared with a current technology, the method has the advantage that the method is capable of firstly reducing a herbaceous tasteof the tea leaves through the natural withering, and accelerating water loss through freezing the tea leaves and spraying the sodium chloride solution without losing nutritional ingredients of tea polyphenol and the like, reducing withering time, improving fragrance and nutritional quality of the tea leaves, guaranteeing adequate and uniform withering through the hot-air withering, further guaranteeing the withering effect through the final withering of the withering tank, and guaranteeing color, flavor and taste and nutrition of a final product of the tea leaves.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a tea withering method. Background technique [0002] Tea is a drink that is widely liked by people. In the process of tea production and processing, the picked fresh tea leaves need to be withered. Withering refers to spreading the tea leaves evenly under certain temperature and humidity conditions to moderately promote the activity of fresh leaf enzymes. , the contained substances undergo moderate physical and chemical changes, and part of the water is emitted, causing the stems and leaves of the tea to wilt, the color is dark green, and the grass gas is lost. At present, traditional withering is mainly divided into natural withering: spread fresh leaves evenly on bamboo curtains or bamboo sieves, and place them in a cool and dry place with air circulation; solar withering: spread fresh leaves evenly in sunlight and wither ; Withering trough withering: spread the fresh ...
