The Mechanical Foam Breaker is used to efficiently break down and reduce the foam generated during the brown stock washing.
In operation, the foam produced during the pulping process is piped to a foam collection chamber, on top of the mechanical foam breaker.
By its continuous formation, the foam is forced upward through the Foam Breaker where it is reduced to liquor by a specially designed high-speed rotor.
The liquor is then centrifugally discharged to the outer chamber and flows through the return line to the lower portion of the tank.
Vapor is exhausted through the Foam Breaker’s upper housing and directed to a vapor-abatement system.
