Reclaimers and suppliers of Bio-Based, and Biodegradable polymers, and processors of PET -particularly Post-consumer regrind -- are currently using drying and/or crystallizing procedures to prevent splay and imperfections in product, as well as maintain intrinsic viscosity. This "conventional" drying process, which has been used for many years, may take as long as six hours. New technology has recently become available which allows moisture removal for processing PET in as little as 8 minutes. This results in substantial energy savings, coupled with allowing the flexibility associated with reduced inventory. The process of Infrared Drying is covered worldwide through several patents resulting from the original filing in Germany. This new drying technology has been improved through years of continuing testing and research to the point that it is now proven to be extremely successful in commercial applications.
