Abstract

Distillers syrup or similar liquid solutions or suspensions of organic solids and oil and water is dried to obtain granular solids with improved syrup content by continuously spraying the syrup or liquid onto the upper surface of a previous bed of granular solids while passing air through the previous bed to dry the syrup from the bottom of the bed upwardly. The upper surface layer of the previous bed is maintained at near saturation temperature of the air entering the bottom of the bed due to the cooling effect of evaporation. The syrup or liquid is continuously mixed into the upper surface layer of the granular solids to significantly increase the dried syrup or liquid content. The bottom layer of the graular solids is continuously cut and continuously removed. The bed is rotated relative to apparatus for spraying the syrup or liquid onto the bed, apparatus for mixing the syrup or liquid into the granular solids, apparatus for cutting the bottom layer of the granular solids and apparatus for removing the cut bottom solids from beneath the bed.
