Some materials in medical applications, such as high temperature polymers, cannot be cooled due to their moisture absorption properties. For these situations, one solution is the Stainless Steel Conveyor (SSC), which cools highly hydroscopic materials during strand pelletizing. The cooling conveyor is for materials such as bio-based plastics, highly filled metal compounds, and certain polymers used in the medical industry that are water soluble.
The cooling conveyor uses a solid stainless-steel belt instead of the standard perforated plastic belt, which typically allows water and air to pass through it. The conveyor belt employs a thin continuous sheet of solid stainless steel to carry the strands, and cooling water under the belt provides the majority of the cooling by transferring heat through the thin layer of metal. Fans placed over the conveyor bring the temperature down an additional few degrees.
The cooling conveyors are available as custom-built units to meet unique requirements of laboratory and specialty compounders.
