Vertical light wine solid-state continuous fermentation equipment and process

Abstract

The invention relates to vertical light wine solid-state continuous fermentation equipment and a vertical light wine solid-state continuous fermentation process, and belongs to the technical field of alcohol production. The vertical light wine solid-state continuous fermentation equipment comprises a vertical fermentation tank, wherein a material distribution device is arranged at the upper part of the vertical fermentation tank, and a discharge port is formed in the lower part of the vertical fermentation tank; an upper discharge plug board and a lower discharge plug board are arranged at the discharge port, and are connected with and controlled by a gear mechanism to be alternately unplugged from or plugged into the vertical fermentation tank to control the continuous sinking discharge of fermented grains respectively. Materials are continuously fed into the fermentation tank and uniformly distributed at a feed port, are fermented into the fermented grains, continuously descend under the action of gravity at the same time, and are controlled by the upper and lower discharge plug boards to be continuously discharged, and the discharge speed is matched with the feeding speed to realize continuous fermentation. The equipment and the process are used for vertical continuous fermentation, and are favorable for improving the quality of a product, and the equipment and production running costs are lowered.

Description

technical field [0001] The invention relates to a vertical solid-state light wine continuous fermentation equipment and technology, belonging to the technical field of alcohol production. Background technique [0002] The process of producing alcohol by solid-state fermentation includes the following three types: [0003] The first one uses underground pools or semi-underground pools as fermentation containers, which are also used to produce edible vinegar, and are characterized by low construction costs. However, the equipment of this process occupies a large area, is difficult to control temperature, has high acid production, high intermittent production cost, easy drying of the fermented grains of the upper fermentation material, and long fermentation time. [0004] The second method adopts a drum horizontal rotary tank for continuous fermentation, and a material copying board is arranged in a rotating drum to realize the function of turning over and mixing the fermented...

AI Technical Summary

Problems solved by technology

The biggest disadvantage of this method is that the energy consumption of the drum rotation is high, and the equipment occupies a large area.

[0005] The third is to use small vertical liquid fermentation tanks in other fields for fermentation production. Due to the limitation of feeding and discharging, only batch fermentation can be completed, the process cannot be continuous, and it is difficult to achieve large-scale production
