Rotocone Vacuum Dryers

In direct heat rotary dryers a continuous feed of wet particulate material is dried by contact with heated air, while being transported along the interior of a rotating cylinder, with the rotating shell acting as the conveying device and stirrer.  We offer rotary dryers in co-current (parallel) and counter-current operation.  In the former the wet material is exposed to the hottest air, which enables heat sensitive or sticky materials to be dried successfully. In the counter-current operation dried material is exposed to the hottest air helping to achieve very low moisture content.  The hot gases may enter the dryer at very high temperature.
