    摘要： The present invention provides a method for determining if air is trapped within a centrifugal separator (100). The separator comprises a stationary frame (30), a rotatable assembly (101) and a drive unit (34) for rotating the rotatable assembly (101) relative the frame (30) around an axis of rotation (X); and further a feed inlet (20) for supply of a liquid mixture to be separated, a first liquid outlet (21) for discharge of a separated liquid phase and a second liquid outlet (22) for discharge of a heavy phase having a density that is higher than said liquid phase; wherein the rotatable assembly (101) comprises a rotor casing (2) enclosing a separation space (17) in which a stack (19) of separation discs is arranged to rotate around a vertical axis (X) of rotation. The method comprises the steps of a) closing one of the first (21) and second (22) liquid outlets and restricting the flow from the other outlet; b) supplying feed to the feed inlet (20) and measuring the flow to the feed inlet (20) and the flow from the restricted outlet (21,22); c) comparing the flow as a function of time between feed inlet (20) and the restricted outlet (21,22); and d) determining that air is trapped within the centrifugal separator (100) if the measured flow as a function of time flow deviates between feed inlet (20) and the restricted outlet (21,22).

    摘要： A centrifugal pellet dryer (100) is shown having a dryer housing (110) with a top cover (115) and a pellet discharge port (132). A perforated rotating basket (112) is disposed within the dryer housing (110) is configured to rotate substantially about a rotational axis (R) to cause pellets to migrate from a closed portion (116) to an open portion (117) is substantially open to allow pellets to escape. A pellet slurry conduit (121) conveys a pellet slurry received at pellet slurry inlet port (118) through the top cover of the dryer housing (110) to the pellet slurry outlet port (120) disposed adjacent the closed portion of the rotating basket (112). A seal assembly (138) is mounted within the dryer housing (110) having water outlet opening and a motor shaft opening that is disposed to intersect the rotational axis, where the seal assembly permits the passage of pellets between the dryer housing and the seal assembly. A water baffle (134) is coupled to the seal assembly (138) to form a water chamber that encloses the rotating basket (112) except for the open portion (117). A water outlet return (136) is coupled to the water outlet opening of the seal assembly (138). A pellet deflector (128) is disposed within the dryer housing (110) and in communication with the open portion (117) of the rotating basket (112) to form a pellet chamber within the dryer housing (110) that is external to the water chamber and in communication with the pellet discharge port (132).
