Problems solved by technology

[0003] The preparation of Liubao tea by modern technology mainly includes fermentation, screening, winnowing, steaming, pressing and cold aging. The fermentation step generally takes 7-15 days, and the fermentation time is relatively long
In addition, although most of the impurities and debris can be removed through sieving and winnowing, there are still a few tiny dust and debris embedded in the fermented tea leaves, which will make the tea leaves dry during the brewing process. The first tea or the second tea is cloudy and the taste is poor

Abstract

The invention discloses a tea leaf blanking device. The tea leaf blanking device comprises a feeding hopper, and the side surface of the feeding hopper is provided with an exhaust pipe and an exhaust fan; the air outlet of the exhaust pipe is connected with the air inlet of the exhaust fan, and the air inlet of the exhaust pipe is arranged above the feeding hopper; a guide pipe connected to a fermentation tank is arranged under a discharging port at the bottom of the feeding hopper. The tea leaf blanking device and a tea leaf blanking process applied to the tea leaf blanking device aim at removing tiny tea dust, shortening the process time of tea making and improving the quality of tea leaves.

Description

technical field [0001] The invention relates to the field of tea production, in particular to a tea blanking device and a tea blanking method. Background technique [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. During the years, it was listed as one of China's top ten famous teas with its unique betel nut fragrance and became a tribute.
