Continuous dark green tea pressing production line

Abstract

The invention relates to a continuous dark green tea pressing production line which comprises a loading inclined conveyer (1), a steamer (2), a pile fermentation cabin (3), a metering conveyer belt (4), a metering module (5), a turntable tea evaporator (6), a tea spreading mechanism (11), a cover plate cleaning and placing mechanism (13), a hydraulic machine (7), a die circulating system (8), a tea discharging conveyer belt (9), a die (10) and a sorter (12). The production line is characterized in that three PLC (Programmable Logic Controller) control cabinets and a central control computer are arranged for the production line and are interconnected with each other through the Ethernet, and the production line can be monitored and controlled through the PLC control cabinets or the central control computer, so that the production line can automatically and continuously press refined and screened raw dark green tea.

Description

technical field [0001] The invention belongs to the field of tea processing machinery, in particular to a fully automatic dark tea processing production equipment. Background technique [0002] Dark tea is one of the six major teas in my country, and the production of dark tea has a long history in my country. Because black tea can help digestion, soften human blood vessels, prevent cardiovascular disease, resist oxidation, delay aging, lower blood sugar, lower cholesterol and other effects, the production and sales of dark tea have increased rapidly in recent years, and there are many processing techniques for dark tea. The patent document with the publication number CN102273527 discloses an improved black tea processing technology, which includes eight processes including greening, rolling, stacking, drying 1, steaming, pressing, fermentation, and drying 2. The improvement of the process It is mainly to reduce the time of fermentation process in the dark tea production pr...

AI Technical Summary

Problems solved by technology

There have been many improvements in the processing technology of black tea, but the production process of dark tea is relatively primitive and the equipment is simple, and complete continuity and automation cannot be realized. The hygiene and safety in the production process still needs to be improved.

The current black tea processing production line cannot get rid of manual intervention, mainly because the process of dark tea processing requires fermentation, stacking, weighing, spreading tea, cleaning and placing cover boards and other processes, and the tea leaves after stacking contain about 15% Compared with the processing of green tea, the realization of complete automation and continuous processing of black tea requires relatively complicated mechanical structure and control
