Description

Technical Field

[0001] The utility model relates to the technical field of tea preparation, in particular to a tea drying and withering rack. Background Art

[0002] Tea withering refers to spreading the leaves evenly under certain temperature and humidity conditions to moderately promote the activity of fresh leaf enzymes, causing moderate physical and chemical changes in the substances contained, releasing some water, causing the stems and leaves to wilt, turn dark green, and lose the smell of grass. Tea withering is divided into three forms: natural withering refers to spreading the fresh leaves evenly on a bamboo curtain or bamboo sieve in a cool and dry place with air circulation; sunlight withering refers to spreading the fresh leaves evenly in the sun for withering; withering trough withering refers to spreading the fresh leaves evenly on a withering trough for withering. During the withering process, the fresh leaves undergo a series of changes, the moisture content decreases, the leaves become soft from being brittle and hard, and are easy to roll into strips; the activity of enzymes contained in the leaves is enhanced, which promotes the decomposition and transformation of fresh leaf components such as starch, protein, and insoluble protopectin, generating glucose, amino acids, soluble pectin and other effective substances that are beneficial to the quality of the finished tea, and polyphenols are also oxidized to varying degrees. The tea drying and withering rack is an auxiliary device structure that needs to be used in the withering process of tea.

[0003] Authorization publication number "CN201878704U" records "a tea drying and withering rack, which includes at least three support rods and more than two horizontal supports, the support rods are vertically arranged, and each horizontal support is horizontally fixed on the support rods. There is a storage space between the upper and lower adjacent horizontal supports, and a sieve is arranged on each horizontal support. The tea drying and withering rack of the utility model enables the drying and withering process of fresh tea leaves to be completed in a relatively small space, and has a large drying capacity and high production efficiency. In addition, the drying and withering rack is flexible in movement, and tea leaves can be flexibly transported according to actual production needs."

[0004] The above patent can be completed in a relatively small space, with a large amount of tea leaves aired and high production efficiency.
