ABSTRACT:
A vacuum transfer system for transferring food grade products. A biased ball in a cage with a substantially uninterrupted cage wall is utilized as a check valve. The ball may be biased by a weight to float in a predictable orientation relative to the cage. The biased ball assures that a certain portion of the ball will consistently engage with and aperture. The biased ball also minimizes chattering of the ball in the cage under high flow conditions.
