In the process of beer production, the sanitary management of equipment is a very critical link. After beer is polluted, it will lead to poor taste of beer, and in serious cases, it will turn sour and turn bad, causing economic losses. In order to ensure a good production environment, beer equipment cleaning and sterilization is essential. CIP cleaning system is the most commonly used cleaning and sterilization equipment, its operation is simple, cleaning and sterilization thoroughly.
The purpose and function of cleaning is to remove yeast, protein solidification, hop resin, oxalate, tartrate, carbonate and other organic and inorganic substances from tank walls and pipelines, so as to prevent abiotic pollution in beer production. The purpose and function of sterilization is to use appropriate fungicides can kill bacteria, fungi and other microorganisms, to prevent biological pollution in beer production.
Sanitation of saccharification equipment: prerinse with clean water for 10 minutes at room temperature; Then 1% ~ 2% sodium hydroxide solution was prepared and heated to 80 ~ 85℃ for CIP circulation for 30 minutes. Next, hot water at 90 ~ 95℃ was used for CIP circulation for 30 ~ 40 minutes.
Health of fermentation equipment: the health condition of the fermentation tank has a great influence on the quality of beer.
At room temperature, rinse directly with clean water; Then 2% ~ 4% alkali solution was prepared and heated to 80 ~ 85℃ for CIP circulation for 30 minutes. Then rinse with clean water for 5 ~ 10 minutes, then allocate 1% ~ 2% nitric acid or sulfuric acid solution to circulate CIP at room temperature for 30 minutes; Then rinse with clean water for 5 ~ 10 minutes, apply 0.35% ~ 0.5% fungicide at room temperature for CIP circulation for 30 minutes, and finally rinse with sterile water to remove the residual fungicide.
Wort cooler health: in general brewery wort cooler is alkaline cleaning, the frequency of cleaning needs in place, because the wort cooling, coagulation precipitate a considerable amount of protein, wine of flower ester, etc., accumulate in the hamper between cooling plate heat exchange effect, to reduce the flow rate of cooling, followed the quality of beer are affected, such as chroma deepened, an indication is aggravating. After alkali washing, rinse off the remaining lye with hot water.
