ABSTRACT:
A frozen comestible freezer with a freezing chamber, a receiving chamber, and a tank of liquid comestible fed to the receiving chamber through an aerator proportioner which provides the correct proportion of liquid comestible and air for the freezing chamber. The aerator proportioner further contains means for isolating pressure exerted by the comestible product in the chamber from the combined pressures exerted by the liquid comestible and atmospheric pressure of air admitted into the receiving chamber, and thereby minimize backflow concerns brought about by pressure imbalance.
