ABSTRACT:
An apparatus and process for removing blowing agent from polymeric foam. The apparatus comprises a comminution zone into which extraction liquid and polymeric foam may be introduced. The upper end of the zone is of larger cross-sectional area and tapers to a lower end of a smaller cross-sectional area. A plurality of blades are located within the comminution zone, and are adapted to comminute the polymeric foam and impart a vortex to the liquid and foam. A quiescent zone is directly connected to the lower end of the comminution zone so that comminuted polymeric foam and extraction liquid may be passed directly from the comminution zone to the quiescent zone. Baffles for attenuating the vortex created in the comminution zone are located within the quiescent zone. The foam then rises to the top of the quiescent zone and is removed.
