LiuBao tea fermentation tank and LiuBao tea fermentation process

Abstract

The invention discloses a Liupu tea fermentation tank. The Liupu tea fermentation tank comprises a tank body 1; one end of the tank body is provided with a gear 3 and a bearing 2, while the other end is provided with a bearing 4; the bearings are arranged on a bearing pedestal 10; the tank wall of the tank body is provided with a discharge hole 6, a feeding hole 5, a sampling hole 9 and a thermometer hole 7 which are respectively provided with a sealing cap; a temperature sensor 8 is arranged in the thermometer hole; a steam inlet pipe 11 with a steam nozzle 15 and a steam inlet pipe 12 with a spraying nozzle 16 are transversely arranged in the tank body; and a shoveling plate 13 and a reinforced steel tube 14 are arranged in the tank body. The process for fermenting tea leaves by using the Liupu tea fermentation tank of the invention comprises the following steps of: putting the tea leaves into the tank body 1 from the feeding hole 5 first; and adding water and feeding steam into the tank body to ferment the tea leaves. In the process for fermenting the tea leaves, the uniform temperature and humidity of the tea leaves can be kept by rolling the fermentation tank. In the Liupu tea fermentation tank and the Liupu tea fermentation process of the invention, because the tea leaves are fermented in a sealed stainless steel tank, the tea leaves can be fermented completely and uniformly, and the health and better quality of the produced Liupu tea can be ensured. The fermentation tank of the invention has the advantages of simple structure, good fermentation effect, and simple operation of the fermentation process.

Description

1. Technical field [0001] The invention belongs to the technical field of Liubao tea processing. 2. Background technology [0002] Liubao tea is a kind of tea, which belongs to black tea category. It is a famous Chinese historical tea with a history of more than 1,500 years. It was named after it was originally produced in Liubao Township, Cangwu County, Wuzhou City. During the Jiaqing period of the Qing Dynasty, it was listed as one of the top ten famous teas in China with its unique betel nut fragrance and became a tribute. Liubao tea is obtained by fermenting, autoclaving, and aging the raw Maocha tea. During the production process, the raw tea is piled up, distributed evenly, and water is added evenly. After it is naturally fermented, the pile is turned over in time, water is added, and the temperature and humidity are well controlled. After the Maocha is evenly fermented, it is dried naturally; then the tea leaves are autoclaved and aged to become Liubao tea. The qua...

AI Technical Summary

Problems solved by technology

Due to artificial watering, it is difficult to control the uniformity of watering, and it is also difficult to control the uniformity of manual turning, so it is difficult to control the temperature and humidity during the fermentation process, which affects the quality of Liubao tea.

In addition, there are disadvantages that are difficult to control in terms of hygiene
