Continuous mode black tea fermentation machine

Abstract

The invention relates to a continuous mode black tea fermentation machine, including: a plurality of sub-fermentation chambers stacked from top to bottom (n >= 2, positive integer), turning plates, aturning plate-driving mechanism and a humid and hot air-generating device. Continuous mode production is realized, and the fermentation efficiency of black tea is improved. Due to the continuous falling of fresh black tea leaves in a top-to-bottom mode, the heavy work of manual charging and discharging is reduced. The fresh leaves in the same fermentation chamber are turned over and evenly mixed during the falling process, thus reducing the manual work and ensuring the uniformity of the fresh leaf fermentation. The sub-fermentation chamber is independent, and multiple sub-fermentation chamberscan be used in reasonable combinations according to the amount of fresh leaves, thus improving the utilization rate of space and energy. Each sub-fermentation chamber is provided with an independentsteam heating device, which improves the flexibility of the equipment.

Description

technical field [0001] The invention relates to the technical field of tea fermentation, in particular to a continuous black tea fermentation machine. Background technique [0002] Black tea fermentation is the key process for the formation of black tea color and aroma. It is a series of chemical changes mainly based on the oxidation and polymerization of polyphenolic compounds. The leaves are in a suitable temperature and humidity environment and in full contact with the air. A better solution at present is to place the rolled leaves in the fermentation box, and achieve the goal by controlling the temperature and humidity of the fermentation box. However, due to the structural problems of the fermentation tank, the energy consumption of the equipment is relatively fixed, the adjustability is low, the energy consumption is relatively high, the temperature, humidity and oxygen control accuracy is low, and the ability to adjust synchronously according to the fermentation proc...

Problems solved by technology

[0004] However, although the above-mentioned technology can supplement the temperature, humidity and oxygen supply in the fermentation heap to a certain extent, the temperature, humidity and oxygen supply differ greatly between the upper and lower layers, and the temperature and humidity of the lower layer are higher than the upper layer, resulting in uneven fermentation
