Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of tea processing equipment, in particular to a white tea withering device with temperature and humidity adjusting functions. BACKGROUND

[0002] White tea is a kind of slightly fermented tea, which is not blanched or twisted, but only naturally withered, dried or dried by slow fire. The appearance of the tea is complete with bud and fine hairs, covered with fine hairs, yellow and clear soup, sweet and mellow taste, high and sweet fragrance, rich honey fragrance, white tea is cool, not only has the effect of reducing fever and reducing fire, but also has pharmacological effect.

[0003] After picking fresh leaves, they should be spread immediately to avoid stacking. Since the freshly picked leaves have a relatively high moisture content, the main purpose of withering is to reduce the water content of fresh leaves and branches and promote the production of complex chemical changes of enzymes. Withering is a key process in tea processing. The withering process is to evenly spread the tea under certain temperature and humidity conditions, to moderately promote the activity of fresh leaf enzymes, to cause moderate physical and chemical changes of the internal substances, to release part of the water, and to make the stems and leaves wilt, dark green in color, and the grassy smell disappears. Withering is different from direct drying. During the withering process, the fresh leaves must be kept in a state of vitality, and the enzymes in the fresh leaves will drive the oxidation of various components, so that the color, aroma and taste of the tea can be formed. It is a key process in tea processing, which determines the color, internal structure and appearance quality of the finished product. Therefore, withering is an important link in white tea technology and plays a key role in the quality of white tea.

[0004] At present, the common white tea processing methods mainly include indoor natural withering, withering with heating and complex withering. Indoor natural withering takes a long time and has a slow production rate. When it encounters rainy weather, the tea leaves cannot be fully dried and withered due to low temperature and high air humidity, which may cause the leaves to turn black or even mold. Withering with heating has high requirements for environmental control technology. If not properly controlled, it may cause uneven withering of white tea, resulting in peculiar smell and affecting the quality of tea leaves.

[0005] After searching, the patent document with authorization announcement No. CN218073333U discloses a temperature and humidity controllable tea withering device, and the patent document with application publication No. CN118661789A discloses a white tea withering room with balanced temperature and humidity. From the contents disclosed in the two patent documents searched, a withering device for white tea withering is provided from different angles. In order to set a stable white tea withering environment, change the existing natural withering method and improve the quality stability of white tea products, it is necessary to provide a withering device different from the existing technology to meet the demand for large-scale withering of white tea.
