Description

Small-sized fermentation device for brewing white spirit

Technical Field

The utility model belongs to the technical field of brewing devices, and particularly relates to a small fermentation device for brewing white spirit.

Background

The white spirit is a wine with Chinese characteristics and belongs to one of distilled wines. A plurality of problems are encountered in the liquor brewing experiment, the experiment selection raw materials are different, the volume of a fermentation container is different, the materials of the fermentation container are different, the use and the use amount of caproic acid bacteria liquid in the fermentation process, how to control the fermentation temperature and the like, and the Luzhou-flavor liquor in large-scale enterprises is fermented by adopting a fermentation tank with a mud bottom wall. The selection of process parameters in the brewing process of a laboratory is different from the selection of large-scale production of enterprises, a fermentation container suitable for laboratory fermentation brewing is selected, and the optimization of laboratory white spirit brewing experiment process parameters is determined to be an important problem. How hang mud and how to protect water scheduling problem will be considered when the research design of small volume fermentation vessel, and the fermentation vessel of reasonable in design structure can guarantee the large area of contact of unstrained spirits and cellar mud, can guarantee again that whole fermentation in-process unstrained spirits upper portion moisture is sufficient, is unlikely to along with going on of fermentation, and the unstrained spirits phenomenon is done to the upper portion of fermented unstrained spirits appearance lack of water, and the influence fermentation goes on. The brewing of white spirit is mixed microorganism fermentation, a certain fermentation temperature needs to be maintained, the reproductive metabolism of microorganisms is ensured, and how to control the fermentation temperature is one of the key factors for success of an experiment.

At present, the commonly used small-capacity fermentation container comprises a plastic barrel, a glass jar and other containers for replacement, the small-capacity fermentation container made of glass is fragile, the operation needs to be carefully carried out, only mud clamping fermentation can be adopted, barrel wall hanging mud fermentation cannot be carried out, the moisture of the upper part of fermented grains cannot be guaranteed, the metabolic fermentation of the moisture content components of the upper part of fermented grains is influenced, the adopted glass container is also a single-layer wall, a heat preservation device is not easy to set, the fermentation effect is not ideal, the quality and the alcohol content of the distilled wine after the fermentation is finished are not ideal, and the clear and transparent distilled wine cannot be obtained.

The plastic small-capacity fermentation container is low in cost, light in weight, not easy to break and convenient to move, but only can be used for fermentation by clamping mud, the wall-mounted mud fermentation of a barrel cannot be adopted, and the moisture of the fermented grains on the upper part cannot be ensured, so that the water loss fermentation of the fermented grains on the upper part cannot be carried out in the later fermentation period, and the raw materials on the upper part cannot be well utilized; the small-capacity fermentation container made of plastic is a single-layer wall, and the fermentation process cannot be insulated, so that the early-stage fermentation temperature rise is slow, the microbial fermentation metabolism is slow, a long fermentation period is needed, the sealing effect is not ideal, and the gas leakage and the bacteria contamination are easy to occur.
