The cleaning of glass bioreactor tanks is more important, and we are constantly striving to improve the cleaning technology of bioreactor tanks in order to make glass bioreactor tanks work for us. The most common cleaning method used in modern breweries is cleaning in place (CIP), which means that the equipment and pipelines are cleaned and sterilized under airtight conditions without disassembling the parts or pipes of the equipment.

Equipment such as bioreactor tanks cannot be cleaned by filling them with cleaning fluid. The in-situ cleaning of the fermenter is carried out through the scrubber cycle. The scrubber has two types: fixed ball type and rotary jet type. The cleaning fluid is sprayed onto the inner surface of the tank through the scrubber, and then the cleaning fluid flows down the tank wall. Generally, the cleaning fluid will form a film attached to On the tank wall. In this way, the mechanical effect is very small, and the cleaning effect is mainly achieved by the chemical action of the cleaning agent.

The fixed ball-washing scrubber has an action radius of 2m. For horizontal bioreactor tanks, multiple scrubbers must be installed. The pressure of the washing liquid at the nozzle outlet of the scrubber should be 0.2~0.3 MPa; for vertical bioreactor tanks and pressure measuring points In the case of the outlet of the washing pump, not only the pressure loss caused by the pipeline resistance, but also the influence of height on the cleaning pressure must be considered. When the pressure is too low, the action radius of the scrubber is small and the flow rate is not enough, and the sprayed cleaning liquid cannot cover the tank wall; when the pressure is too high, the glass bioreactor tank cleaning liquid will form a mist and cannot form a downward flow along the tank wall The water film or sprayed cleaning fluid is bounced back by the tank wall, reducing the cleaning effect.
