Health and safety management of Bioreactor
In the process of beer production, bioreactor plant health thought process is a crucial link. After the pollution of beer, can lead to the taste of beer, serious when still can make sour beer deterioration, caused economic losses. In order to guarantee the good production environment, bioreactor cleaning and sterilization is necessary. The CIP cleaning system is the most commonly used cleaning and sterilization of equipment and its operation is simple, clean and sterilize thoroughly.
Purpose and the role of cleaning is clear the yeast on the tank wall, pipe, protein coagulum, hop resin, oxalic acid, tartaric acid salt, salt carbonate and other organic and inorganic substances, prevent beer non-biological pollution in production; The purpose and function of sterilization is to use suitable fungicide to kill bacteria, fungi and other microorganisms to prevent the biological pollution in beer production.
Sanitation of Bioreactor: at normal temperature, 10min preflush with clear water; Then configure 1% ~ 2% sodium hydroxide solution, heating to 80 ~ 85 ℃ for 30 min CIP cycle; The next in 90 ~ 95 ℃ hot water for 30 ~ 40 min CIP cycle.
Hygiene of Bioreactor: the health of the starter can have a great influence on the quality of beer. Cleaning and asepsis is the most basic requirement of the fermentation tank.
Under normal temperature, rinse directly with clean water; Then configure 2% ~ 4% of alkaline solution, CIP cycle heating to 80 ~ 85 ℃ for 30 min. Then rinse 5-10min with water, and then allocate 1 ~ 2% nitric acid or sulphate solution to the CIP cycle 30min at room temperature. The CIP circulates for 30min with 0.35% ~ 0.5% of fungicide, and then rinsed 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 alkaline cleaning, use hot water to wash away the remnants of lye.
Bioreactor plant remind you both beer and food safety is the first, then what should pay attention to safety in the process of beer production, purpose and the role of cleaning is clear the yeast on the tank wall, pipe, protein coagulum, hop resin, oxalic acid, tartaric acid salt, salt carbonate and other organic and inorganic substances, prevent beer non-biological pollution in production; The purpose and function of sterilization is to use suitable fungicide to kill bacteria, fungi and other microorganisms to prevent the biological pollution in beer production.
We all know that small bioreactor to produce contains a certain amount of active yeast in beer, so we say that under certain conditions active yeast for secondary fermentation, therefore save protoplasmic home-brewed beer needs some necessary condition, according to the character of the beer is necessary to determine the specific conditions.
1. Protoplasmic small bioreactor to produce beer preservation must be strictly in accordance with the production time, product categories, respectively, placed neatly done disinfection warehouse first and then sales, it is important to note that not in the refrigerator for too long.
2. The temperature requirement of the original beer is more strict than that of other beer without yeast. The temperature in the cold storage must be suitable and can have certain inhibitory effects.
Ventilation is also key, and we say that if the ventilation is not good, maybe I make our label go bad.
4. The original beer can not be placed directly in the outdoor environment, so as to prevent sunshine and rain, avoid direct sunlight.
That needs to be suitable for small bioreactor in home-brewed home-brewed conditions, to produce high quality of beer, the above is the basic condition of home-brewed small bioreactor, to professional must understand oh!
