The cleaning of the glass fermenter is more important, and we are constantly working to improve the cleaning technology of the fermenter, in order to make the glass fermenter work for us better.
The most common cleaning method used in modern breweries is cleaning in place (CIP for short), which is a method of cleaning and sterilizing equipment and pipelines without dismantling the parts or pipes of the equipment under airtight conditions.
Equipment like glass fermenters cannot be cleaned by filling them with cleaning fluid. In-situ cleaning of the fermenter is performed through a scrubber cycle. There are two types of scrubbers: fixed ball washing type and rotary jet type. The cleaning liquid is sprayed onto the inner surface of the tank through the washer, and then the cleaning liquid flows down along the tank wall. on the tank wall. In this way, the effect of mechanical action is very small, and the cleaning effect is mainly achieved by the chemical action of the cleaning agent.
The radius of action of the fixed ball scrubber is 2m. For the horizontal fermentation tank, multiple scrubbers must be installed, and the pressure of the washing liquid at the nozzle outlet of the scrubber should be 0.2-0.3 MPa; for the vertical fermentation tank and the pressure measurement point In the case of the washing pump outlet, not only the pressure loss caused by the pipeline resistance, but also the influence of the height on the washing pressure should be considered.
When the pressure is too low, the action radius of the scrubber is small, the flow rate is not enough, and the sprayed cleaning liquid cannot cover the tank wall; and when the pressure is too high, the cleaning liquid of the glass fermentation tank will form a mist and cannot form a flow down the tank wall. The water film, or the sprayed cleaning liquid, bounces back from the tank wall, reducing the cleaning effect.
