Description

Technical Field

[0001] The utility model relates to the technical field of tea withering machines, in particular to a tea withering machine which can prevent the accumulation of tea leaves inside. Background Art

[0002] Withering of fresh leaves is an important process in the primary processing of black tea. The withering process causes physical and chemical changes in the tea leaves, which has a great impact on the appearance and internal quality of the tea leaves in the subsequent process. The purpose of withering is to evaporate water, reduce cell tension, and soften the leaves, making them easier to roll. At the same time, it enhances the activity of enzymes and causes a certain degree of change in the internal components, thus laying a solid foundation for the excellent quality of black tea. The suitable temperature and humidity for tea withering vary depending on the type of tea and the production process, but generally speaking, withering needs to be carried out under suitable temperature and humidity conditions to ensure that the tea leaves can be evenly spread and undergo appropriate physical and chemical changes. There are many methods for tea withering, including natural withering, sunlight withering, heated withering, and compound withering. Natural withering is to spread the fresh leaves evenly on a bamboo curtain or bamboo sieve and place them in a cool and dry place with good air circulation. Sunlight withering is to spread the fresh leaves evenly under sunlight for drying. Heated withering is to heat the withering process by heat pumps, hot air blowers and other equipment. Compound withering is a combination of two or more withering methods.
