Description

Technical Field

[0001] The invention relates to multifunctional withering-drying-aging integrated equipment in the field of tea or traditional Chinese medicine and a use process thereof. Background Art

[0002] White tea is a tea product made from fresh leaves of white tea varieties with buds and leaves covered with fuzz, and made according to the white tea processing technology. Compared with other teas, white tea has a fresh and mellow taste and a fresh and fragrant aroma due to the particularity of raw materials and processes. It also has health benefits such as clearing away heat and detoxification, promoting body fluid and quenching thirst, relieving heat and promoting diuresis, and calming the liver and suppressing yang. For traditional white tea products, there are mainly white silver needle, white peony, Gongmei and Shoumei, and their processing technology is mainly fresh leaves → withering → drying. For pressed and aged white tea, its processing technology is withering → pressing → drying → aging. Common varieties of black tea include Anhua black tea, Guangxi Liubao tea, Shaanxi Fu tea, Hubei green brick tea, Sichuan Tibetan tea, etc. Aging is the last link in the processing of black tea, and it is also the key process for secondary quality improvement. However, current aging is mostly based on experience. Tangerine peel is a commonly used Chinese medicine in clinical practice. It is the dried and mature peel of the citrus plant and its cultivated varieties of the Rutaceae family. The authentic medicinal material is the peel of the tea branch orange in Xinhui, Guangdong. Tangerine peel has the effects of regulating qi and strengthening the spleen, drying dampness and removing phlegm. Tangerine peel needs to be aged at a suitable temperature. Too high a temperature will cause the peel to burn, and too low a temperature will not produce a good aging effect. The humidity of the space where tangerine peel is stored must be controlled within a certain range, otherwise it will easily become moldy and worm-eaten. Tangerine peel needs to be in contact with air to be aged. If it is stored too tightly for a long time, it will not be conducive to the aging of tangerine peel.

[0003] The existing withering methods of white tea mainly include natural withering in indoor, composite withering in sunlight indoor, temperature controlled withering, humidity controlled withering, etc.; withering also needs to control humidity. Withering in the tea making process refers to the process in which fresh leaves lose water after a period of time, so that certain hard and brittle stems and leaves become wilted and withered. It is an important process in the initial processing of tea. After withering, water can be evaporated appropriately, the leaves are soft, the toughness is enhanced, and it is easy to shape. The existing drying methods mainly include natural sun drying, electric heating drying, heat pump drying, etc. The existing aging method is mainly natural aging, and the aging conditions such as temperature, humidity, oxygen, and light cannot be controlled. With the extension of the withering / drying / aging time of white tea, under the joint influence of factors such as temperature, humidity, oxygen, light conditions and microbial action, the sensory quality of white tea shows a certain change law, and its main quality components and aroma components will change in different trends and degrees during the processing process. The quality of white tea is improved and improved within a certain time range, and it has a trend of "the older the better".

[0004] CN106135500 B relates to a white tea and a rapid aging method thereof, wherein the raw white tea is placed in an aging room for aging for 6 to 9 months and the raw white tea is irradiated with ultraviolet light. CN103535451 B discloses a rapid aging method for black tea, wherein the sun-dried raw green tea is treated under an electric field. CN103932086 A provides a rapid aging method for tangerine peel, wherein the tangerine peel is placed in a sealed container and oxygen or pure air is continuously introduced, thereby obtaining tangerine peel with good aging quality. CN109517712 A discloses a method and equipment for rapid aging of new wine, comprising an aging tank, an oxidation system composed of a microwave generator, an electrodeless tube, a quartz plate, and oxygen input, a hydrogen reduction system, an ingredient addition pipeline, an agitator, an exhaust port, and a control system composed of a gas detection sensor and a control panel. All of the above patents are completely different from the present invention and have obvious differences. The invention patent mainly relates to a multifunctional withering-drying-aging integrated device and its use process.

[0005] From a technical and economic perspective, the present invention proposes a multifunctional withering-drying-aging integrated equipment and a use process thereof, which can be applicable to white tea, black tea, oolong tea, dark tea, tangerine peel, etc. The multifunctional withering-drying-aging integrated equipment can not only improve the withering efficiency and quality, but also achieve energy saving and consumption reduction in the drying process, enhance the aroma of tea or traditional Chinese medicine, and can significantly shorten the aging time and improve the aging quality. It has high economic benefits and is of great significance for promoting the actual production level of withering, drying and aging in enterprises. Summary of the invention
