Abstract

A method and apparatus for drying particulate material such as bark by forming a circulating bed of other material to be dried, which bed, being guided by wires, moves on an endless web around two wire turning rolls. Material to be dried is continuously fed onto the bed and dried material is continuously discharged from the innermost layers of the bed, such that the thickness of the bed remains constant. The material to be dried is discharged by means of a dosing cell roll, which is disposed in the opening between the horizontal section of the first wire loop and the horizontal section of the second wire loop.
