A preheating and pulsating small-scale tea greening device

Abstract

The invention discloses a preheating and pulsating small-sized tea greening device, which comprises a box body, a first hot air blower and a second hot air blower are respectively arranged on the left and right side walls of the box body, and a sleeve is installed at the bottom of the box body. The inner side of the sleeve is equipped with a central tube for cooperating with the rotation, the bottom of the box body is installed with a driven gear on the central tube, the driven gear is meshed with the driving gear on the output shaft of the drive motor, and the upper part of the central tube is fixed with a killing disc. A number of cavities are evenly opened in the circumferential direction of the fixing disc, and a fixing net cylinder is arranged in the cavity, and a plurality of support springs are arranged on the outside of the fixing net cylinder, and a plurality of fan blades are arranged on the cavity wall, and the fixing net cylinder is equipped with multiple supporting springs. A left blowing pipe and a right blowing pipe are respectively arranged on the left and right sides of the bottom of the disk, and the lower ends of the left blowing pipe and the right blowing pipe are communicated with the left preheating chamber and the right preheating chamber respectively. The invention has novel structure, reasonable design, good tea greening effect and high quality.

Description

Technical field [0001] The present invention relates to the field of tea production equipment, in particular a preheating pulsation type small tea killup device. Background technique [0002] Tea is from China. The tea is first used as a sacrifice. However, from the late spring and autumn, it is used as a snack in the middle of the Western Han Dynasty. The Western Han Dynasty has developed into a court high-grade drink. The popularity of the people as ordinary drinks is the West Jin In the future. The remains of the earliest and artificial planting tea were found in Yuyao, Zhejiang Province, has more than 6,000 years of history, and add tea with various tea or refined tea, including tea, tight tea, extract tea, medicine Health tea, tea drink, etc. [0003] In the current tea processing production, the existing traditional rollers used in the tea killing process are mainly using firewood and coal burning open fire. Direct heating drums to achieve tea, the main disadvantages and pr...

Problems solved by technology

[0003] In the current tea processing and production, the existing traditional roller degreening machine used in the tea degreening process mainly uses firewood and coal to burn open flames to directly heat the drum to achieve tea degreening. The main disadvantages and problems are: the degreening temperature is not easy control, the temperature fluctuates greatly, resulting in uneven finishing; the dehumidification of the discharge end leads to "stuffy" phenomenon, which affects the color, aroma and taste of tea; its energy consumption is relatively high, and its thermal efficiency is low; firewood and coal combustion pollute surroundings
