The Heat Systems screw conveyor is a simple, robust and flexible device, which is often employed to adjust the temperature of a solid material prior to storage or further processing. The unit is essentially a screw conveyor with heat transfer capability, providing both material movement and temperature adjustment in one device.
Other suppliers typically employ an external jacket to act as the sole heat transfer surface. The problem is that this surface has limited contact with the material due to voidage and movement, generally resulting in a larger unit than necessary being specified to compensate. However, the Heat Systems conveyor also uses the screw itself to supply or withdraw heat, thereby penetrating deep into the solid which is often a poor conductor (e.g. spent carbon). This effectively results in a smaller, more compact footprint and cost.
A liquid heat transfer medium ensures stable and precise control of the final product temperature (e.g. cooling water, thermal oil, glycol etc). As always, custom designs are available to suit your individual need.
