Automated Congou black tea production process

Abstract

The invention discloses an automated Congou black tea production process, which includes a staged dynamic withering technique, a continuous and progressive pressure rolling technique, a high-speed rotational deblocking technique, a variable-temperature dynamic fermentation technique, a microwave tempering and dehydration technique and the like; the staged dynamic withering technique is carried out by four automatic vertical withering machines, the continuous and progressive pressure rolling technique is carried out by six 65 model automatic rolling machines, the high-speed rotational deblocking technique is carried out by a high-speed rotating roller type deblocking machine, the fermentation temperatures of different stages are controlled by an automatic fermentation machine in the variable-temperature dynamic fermentation technique, and on-line tempering is carried out by a microwave tempering machine in the microwave tempering and dehydration technique. The automatic vertical withering machines, the automatic rolling machines, the high-speed rotating roller type deblocking machine, the automatic fermentation machine, the microwave tempering machine, two automatic driers and other equipment are connected through a production line and adopt an automatic control system, consequently, Congou black tea processing realizes automated, continuous and clean production, the quality and sanitary quality of the tea are increased, and the working efficiency is remarkably increased.

Description

technical field [0001] The present invention relates to the continuous and automatic process of primary processing of Gongfu black tea, which mainly consists of segmental dynamic withering technology, continuous and progressive pressurized rolling technology, high-speed rotary deblocking technology, variable temperature dynamic fermentation technology, microwave dehydration technology, etc. The primary automatic production process of the formed Gongfu black tea. Background technique [0002] The primary process of Gongfu black tea includes withering, rolling, fermentation and drying. The current withering process generally adopts the hot air trough withering, the temperature is 35° C., and the time is 4-6 hours. The upper and lower leaves are manually operated, and the average daily withering fresh leaves of each withering trough is 400-500 kg. The kneading process is mainly kneaded with 55-type, 65-type kneading machines, and the time is 60-70 minutes. Kneading is divid...

AI Technical Summary

Problems solved by technology

In the primary production process, the technical conditions of each process must be mastered by skilled technical workers. Different people have different quality due to different mastering conditions; the connection between each process is not continuous, and the upper and lower leaves are manually operated. Scattered on the ground, not only difficult to meet the requirements of food processing hygiene, but also low work efficiency and high labor intensity
