Abstract
A rotary particle dryer has a shaft extending along an axis and a hollow drum coaxially and spacedly surrounding the shaft and rotatable about the axis in a direction. A set of axially extending inner baffles fixed to the shaft extend radially outward therefrom and each form at least one angularly open inner pocket. A set of axially extending outer baffles fixed to the drum extend radially inward therefrom and each form at least two angularly open outer pockets. Structure mechanically connects the inner baffles directly with the outer baffles.
Claims13
A rotary particle dryer comprising:
- a shaft extending along an axis;
- a hollow drum coaxially and spacedly surrounding the shaft, rotatable about the axis in a direction, and having one end forming around the shaft an axially open inlet and an opposite end forming around the shaft an axially open outlet;
- a set of axially extending inner baffles fixed to the shaft, extending radially outward therefrom, having radially outer ends, and forming radially outwardly and axially open inner pockets radially inwardly closed by the shaft;
- a set of axially extending outer baffles fixed to the drum, extending radially inward therefrom, having radially inner ends, and forming radially inwardly and axially open outer pockets radially outwardly closed by the drum, the inner-baffle outer ends being spaced radially inward of the outer baffle inner ends;
- and
- structure connecting the inner baffles directly with the outer baffles such that particles can flow freely radially between the inner and outer pockets.
