The basic method of cleaning the fermenter Flush all the foam inside the fermenter with water —–>Cycle cleaning with 2.0%-4.0% alkaline solution for about 30 minutes —–>Flush water to ph value of neutral —–>Cycle cleaning with disinfectant for more than 10 minutes. According to the above theory, we can design the following CIP cleaning process. 1）Alkaline wash + acid wash + disinfection 2）Alkaline wash + sterilization 3）Acid wash + sterilization
Normally, the washing solution should be discharged every 6-8 weeks.
Washing solution and disinfectant should be checked twice a week.
Check regularly whether the detection accessories of CIP system are working properly.
