Abstract
A technique facilitates mixing operations by removing foaming that results from air entrained during mixing of constituents. A mixing system comprises a container body having an interior and an inlet through which material enters the interior for mixing. The container body also comprises a discharge through which the mixed material is delivered downstream. A mechanical foam breaker is disposed within the container body and extends upwardly a sufficient distance to extend through a surface level to which the material rises during mixing within the container body. The mechanical foam breaker is oriented to break down foam along the surface of the material as the material moves through the interior.
