Abstract
The continuous dryer of the invention is essentially characterized in that in addition to blades, said rotor is provided with at least one centrifuging element extending along the entire axis of the rotor advantageously in a helical pattern in the product discharge direction, said centrifuging element being shaped in the form of a rib with a height less than the height of said blades and so calculated as to act as a device for limiting the product layer present on the heated surface of said cylinder.
Claims15
A continuous dryer for a product, said dryer comprising:
- a) a substantially horizontal static cylinder, having product loading and discharge apertures in said static cylinder and heating means associated with said static cylinder for heating a cylindrical inner surface of said static cylinder;
- b) a substantially cylindric rotor in said static cylinder and defining a substantially cylindrical gap with said inner surface;
- c) at least two angularly displaced blade arrangements on said rotor, each arrangement extending along a generatrix of the substantially cylindric rotor and for substantially the whole length of the rotor and each arrangement comprising a plurality of spaced blade means (16) inclined with respect to a plane perpendicular to said rotor and extending within said gap for a certain radial height;
- d) driving means for transmitting rotation to said rotor;
- e) at least one centrifuging means (13) extending between the two blade arrangements along a generatrix of the substantially cylindric rotor and for substantially the whole length of the rotor and extending within said gap for a radial height less than said certain radial height of said plurality of blade means.
