Industry Organic Polymer KJG-5 Harrow Paddle Rotary Vacuum Dryer

Industry Organic Polymer KJG-5 Harrow Paddle Rotary Vacuum Dryer

The continuous horizontal paddle dryer consists of a jacketed trough and two hollow shafts with hollow paddles. On the trough is a cover with the inlet for the material to be dried. The material is dried by heat transfer with the heating medium like steam, thermal oil or hot water which is flowing through the hollow shafts, hollow paddles and dimple jacket or half pipe jacket. The dried product is removed from the discharge chute via a shaftless screw conveyor. The exhaust vapors leave the dryer through an exhaust outlet on the cover. The absence of air during the drying process results in a very safe operation due to lowest oxygen content, a small and compact odour treatment and it offers the possibility of a heat recovery system in the vapour condensing unit due to the high dew point of the off-gas.

The trough is omega shaped with a jacket. The material is fed at one end of the machine and will be transported by gravity, under a slight angle of the trough or by asymmetric paddles, to the outlet of the machine at the other end. During the residence time of the material in the machine, a perfect plug flow is maintained, guaranteeing perfect uniform product quality. The product level inside the machine is secured by an adjustable overflow weir. Overflow weir at the product outlet side has manually operated emptying valves at the bottom of the product removal before a production stop. Product outlet chute at the bottom of the trough has a rectangular flange to connect to the downstream equipment.
