New way to dry PET will debut at NPE 2006.At the giant NPE NPE NullPointerException (Java) NPE Network Processing Engine NPE National Policy on Education NPE National Plastics Exposition NPE Natural Penis Enlargement NPE Nutrition Program for the Elderly show in Chicago this June, Baltimore-based Novatec, Inc. will introduce what it describes as a "revolutionary" new dryer/crystallizer for PET. This patented infrared rotary-drum (IRD IRD Institut de Recherche pour le Développement (French) IRD Inland Revenue Department (New Zealand's tax revenue collection department) IRD Integrated Receiver Decoder ) unit reportedly uses much less energy than a conventional desiccant desiccant /des·ic·cant/ (des´i-kant) 1. promoting dryness. 2. an agent that promotes dryness. des·ic·cant n. dryer, providing lower cost and fast ROI (Return On Investment) The monetary benefits derived from having spent money on developing or revising a system. In the IT world, there are more ways to compute ROI than Carter has liver pills (and for those of you who never heard of that expression, it means a lot). . The IRD reportedly can crystallize crys·tal·lize also crys·tal·ize v. crys·tal·lized also crys·tal·ized, crys·tal·liz·ing also crys·tal·iz·ing, crys·tal·liz·es also crys·tal·iz·es v.tr. 1. PET and reduce its moisture content to less than 50 ppm in under 15 min in one continuous operation. It's aimed at processors of thin sheet, film, and bottles. As shown in the diagram, a controlled flow of PET enters a large, rotating, stainless-steel cylinder that has an auger-like helix welded inside. Banks of IR heaters emit radiation that passes through the air without heating it, so all of the energy is directed into the resin. IR energy heats the resin particles from the inside out (the opposite of usual), driving the moisture to the surface to be evaporated evaporated reduced in volume by evaporation; concentrated to a denser form. . A stream of ambient air is forced through the drum to carry off the moisture. As the cylinder turns, the resin tumbles, exposing all the particles to IR heating. Due to the internal helix, cylinder rotation also transports the material along the drum in 8 to 13 min. The system has no desiccant, valves, regeneration heater, or cooling coil. Material temperature and other functions are monitored on a Siemens touch-screen controller. Five sizes of IRD process 400 to 8000 lb/hr. Larger sizes can be designed.
