Problems solved by technology

The problem is that the working environment in the fermentation room is relatively harsh, the working state of the mechanical device in this working environment is unreliable, and the oxides and heavy metals of the equipment are easy to pollute the tea, such as the conveying metal mesh, bearing lubricating oil, etc. contain heavy metal content
And the equipment is in a continuous working state, and the energy consumption is relatively high

Embodiment 1

[0028] like Figure 1~3 Among them, an automated tea fermentation system, the fermentation tunnel is provided with a passage for the fermentation box 8 to pass through, a pushing device is provided at one end of the fermentation tunnel, and a discharge device 12 is provided at the other end;

[0029] A water mist nozzle 9 and a heating device are provided in the fermentation tunnel. The outer wall of the fermentation tunnel is made of thermal insulation materials, such as foam boards, to reduce energy consumption and manufacturing costs. At the entrance and exit of the fermentation tunnel, there are silicone curtains to reduce the waste of hot air. The material pushing device in this example adopts a cylinder, and the fermentation tank 8 is pushed to feed by the material pushing device. In this example, the feed end is the head end, and the discharge end is the tail end. Unloading relies on the thrust transmitted between the fermentation tanks 8 to realize the discharge, an...

Embodiment 2

[0040] A method for tea fermentation using the above-mentioned automated tea fermentation system, comprising the following steps:

[0041] Put the fresh leaves into the fermentation box 8, and push the fermentation box 8 into the fermentation tunnel in turn by the pushing device to ferment, and control the oxygen content, temperature and humidity during the fermentation process;

[0042] After the fermentation is completed, the pushing device pushes the fermentation tank 8 to the unloading device;

[0043] Automatic tea fermentation is realized through the above steps.

[0044] More specific steps are:

[0045] The feeding device 2 is usually a flat belt machine or a hoist, which transports the tea leaves after kneading and deblocking to the weighing hopper 3, and stops after reaching the set weight. The bottom box conveying device 84 transports the bottom box 81 of the fermentation box to the bottom of the weighing hopper 3, and the gate at the bottom of the weighing hopper...

Abstract

The invention relates to an automatic tea fermentation system. A passage for enabling a fertilization box to pass through is formed in a fermentation tunnel; a pushing device is arranged at one end of the fermentation tunnel; a discharge device is arranged at the other end of the fermentation tunnel; and a water mist spray pipe and a heating device are arranged in the fermentation tunnel. A fermentation method employing the above-mentioned automatic tea fermentation systems comprises the steps of: loading fresh leaves into fermentation tanks; pushing the fermentation tanks into a fermentation tunnel in turn by a pusher; controlling oxygen content, temperature and humidity in the fermentation process; after fermentation, pushing the fermentation tanks to unloading equipment by the pusher, so as to realize automatic tea fermentation. The invention employs a structure containing the fermentation tunnel located in the fermentation chamber cooperated with the pusher, and reduces the volume of the fermentation space, thereby reducing energy consumption radically and reducing the chance of contamination by bacteria as well.

Description

technical field [0001] The invention relates to the field of tea processing equipment, in particular to an automatic tea fermentation system and method. Background technique [0002] In existing tea production, such as black tea production, fermentation is an essential link, and the traditional way is to ferment in a fermentation room. However, the randomness of the traditional fermentation method is large, it is difficult to control the temperature and humidity, it is easy to produce bacteria, and it is difficult to guarantee the quality of the finished tea. [0003] Chinese patent document CN104146086A improves the quality control of fermentation by arranging heating and aeration devices in the fermentation chamber. However, the cost of this solution is relatively high, and the use of solar heating can only be used as an auxiliary heating energy source, which is not reliable enough. [0004] Chinese patent document CN 103238688 A discloses a tea fermentation device and i...
