The Vacuum Deaerator is used for derating / removing gases and air from liquids, semi-liquids
and semisolids pasty materials. It is a continuously operating machine consisting of tank having
deep cone and shallow shell with closed top end. Top entering rotating disc with suitable drive
will be provided underneath top end. Product is fed into vacuum vessel at the center of rotating
disc. Due to centrifugal forces product is passed through peripheral screen of rotating disc and
layered on inner vessel wall. Due to this action any pockets / gases in the product are braked
and released from vessel by means of vacuum pumping action.
Oxygen pockets emended in viscous liquid offer products negative effects like – oxidation, decom position of fat and oil degeneration of test and smell, porosity in coating and paints surfaces.
