A deflector mounted on the internal surface of a cylindrical screen in a centrifugal pellet dryer. The deflector is one or more vertical strips mounted in spaced relation on the interior surface of the screen by bolting to mating mounting strips on the outside of the screen. The deflector strips deflect the pellets moving along the interior surface of the screen. The edge of the deflector strip facing the direction of movement of the circulating pellets is inclined to deflect the pellets back toward the rotor. In another form, the deflector strip has angled flanges with one flange clamped between outwardly extending vertical side edge flanges on the cylindrical screen. The other flange extends at an oblique angle to deflect the circulating pellets back toward the rotor.
A deflector for the interior surface of a generally cylindrical vertically disposed screen in a vertical centrifugal pellet dryer, said deflector comprising at least one vertical deflecting strip supported from said screen and positioned along the interior surface of the screen in generally parallel relation to the rotational axis of a driven bladed rotor operating within the screen for lifting and moving water laden pellets outwardly in a circular path to impact with the screen to separate water from the pellets for discharge of the water through the screen, said vertical strip including an inclined surface forming a leading edge oriented in opposed relation to circular movement of the pellets along the interior surface of the screen to deflect the pellets toward the rotor.
In combination with a dryer having a cylindrical screen and a driven bladed rotor disposed within said screen for moving moisture laden particles longitudinally of the screen and radially outwardly for impact with said screen for separating moisture from the particles and discharge of the moisture through the screen, said cylindrical screen having vertical aligned end edges, said combination further including at least one generally vertical extending deflector strip mounted on an inner surface of said screen spaced from said vertically aligned end edges for interrupting a flow of particles moving along an inner surface of the screen.
A cylindrical pellet dryer which comprises a generally cylindrical vertically disposed screen or aligned screen sections, a driven bladed rotor operating within said screen or screen sections for lifting and moving water laden particles outwardly in a circular path to impact with the screen to separate water from the particles for discharge of the water through said screen or screen sections, and at least one vertically extending elongated deflecting strip positioned on an interior surface of said screen in generally parallel relation to a rotational axis of the driven bladed rotor to interrupt a flow of particles moving along an inner surface of said screen or screen sections.
