Sterile treatment method and device of water for fermentation

Abstract

The invention relates to a sterile treatment method and device of water for fermentation. A pH value of incoming water in a stainless steel water tank is regulated to 6.5-8.0, the raw water passes a multimedium filtration system through a pressure device to remove suspended solids and colloids in water; the primarily filtered raw water is fed into an efficient biofilm system, the system conducts fine treatment, and then produced water is fed into a pure water storage tank; an ultraviolet sterilization system is arranged before a water use point and used for removing bacteria passing through apipeline, and the water quality at the water use point is maintained; an online chemical cleaning system is used for cleaning the filtration system, the film system and the storage tank; a chemical cleaning agent is stored in a cleaning water tank, is pressurized by a dosage pump and then is fed into a cleaning agent filter, and a filtered cleaning agent is used for conducting sterilization and cleaning on the multimedium filtration system, the efficient biofilm system and the storage system. By adopting the above combined treatment mode, the granular substances and bacteria in water can be effectively removed, and treated water can meet the demand for water for fermentation.

Description

technical field [0001] The invention relates to the technical field of aseptic treatment of fermentation water, in particular to a method for aseptic treatment of fermentation water and a device thereof. Background technique [0002] In recent years, high-end beverages have gradually occupied the market; among them, for fermented high-end beverages, high-quality water sources have become a difficult problem for high-end beverage manufacturers; specifically, high-end beverages mainly include: beer, liquor, wine and other alcoholic beverages; high-end flavors Dairy products; fruit vinegar. For the above beverages, the quality of brewing water directly affects their quality and taste. In the existing market, the water production process used has poor control over bacteria in the production process; such as: precipitation method, adsorption method, rough filtration method, etc. The use of traditional water production technology introduces miscellaneous bacteria during the ferm...

AI Technical Summary

Problems solved by technology

In the existing market, the water production process used has poor control over bacteria in the production process; such as: precipitation method, adsorption method, rough filtration method, etc.

The use of traditional water production technology introduces miscellaneous bacteria during the fermentation process, which directly affects the effect of fermentation; and some of these miscellaneous bacteria originate from unclean water sources
