    Abstract: The disclosed system comprises an apparatus and a method continuously removing air from a mixture of ground polyurethane particles and a polyol liquid. The apparatus for continuously removing air from a mixture of ground polyurethane particles and a polyol liquid comprises a deaerator having an inlet to receive a mixture of liquid and fine particles and an outlet to disperse the mixture. The deaerator further comprises a rotating bowl, wherein the bowl is attached to a shaft so that the bowl and the shaft rotate. The bowl has an inside and an outside surface that is coupled to the inlet of the deaerator to receive the mixture such that when the bowl is rotated, the mixture is spread on the inside surface of the bowl. A pickup tube is located in the bowl that catches the mixture and directs it through a conduit to the outlet. The rotation of the bowl imparts sufficient energy to the mixture to pump it through the conduit. A vacuum chamber that has a front plate and a back plate encompasses the bowl and the back plate contains an assembly by which the shaft rotates and the low absolute pressure within the vacuum chamber prevents bubbles from being re-entrained in the mixture as it is directed toward the outlet via the conduit.
