Material Drying Equipment

It may sound to good to be true, but Italian auxiliary maker Moretto SpA (Massanzago, Italy) is offering its fully automatic high-volume modular Eureka drying systems, combining the new X Max dryer, the Flowmatik controller, and the new OTX hopper at no up-front cost to the processor. Visitors to the upcoming K Show can learn more at Stand 11/H57.

Loss-in-weight control, airflow management and stabilization, an intelligent regeneration process, and advanced industrial PC-based control combine in an auto-adaptive PET resin drying solution that claims to deliver the lowest possible energy consumption.

The Genesys desiccant dryer from Piovan (Venezia, Italy) features integrated automatic air flow control and adjustment to reduce energy consumption by a reported 30%–55% compared with today’s conventional resin drying systems.

Loss-in-weight control, airflow management and stabilization, an intelligent regeneration process, and advanced industrial PC-based control are hallmarks of this next-generation system for PET resin drying, and Piovan claims that it is the only “auto-adaptive” system available on the market today.

A new range of plastics dryers is targeting processors’ increasing desire for auxiliary equipment able to help them process low-throughput, high-end materials. Called Precision Micro dryers and made and marketed by Dri-Air Industries (East Windsor, CT), these dessicant dryers are able to process from two pellets to 20 lb/hr, with drying temperatures from 70–400°F. No cooling water or after coolers are needed. A continuous stream of –49°F dew point air is generated regardless of the ambient conditions in a facility.

A new drying system from The Conair Group Inc. (Cranberry Township, PA) is said to allow processors to optimize drying conditions and thereby save energy. The EnergySmart Single-Stage (ES-1) system was developed for processors of PET and other polymers that require high drying temperatures, applications in which throughput varies, and where electrical costs are high.

Novatec (Baltimore, MD) has added a 75-lb/hr compressed air-type dryer to its existing range of cost-effective NovaDrier models with throughputs of 7, 25, 50, 100, 150, and 225 lb/hr.

New from auxiliary equipment manufacturer Koch (Ispringen, Germany) is the KEM range of direct-dying machines, marketed as a value-for-money piece of kit when a processor needs to dose masterbatch directly into the input area of a plasticizing screw.

A unique airflow pattern and a new wheel dryer design on the new InteliPET drying system is made to help PET processors save on energy, maintenance, and plant space.

A new dryer that uses the rapid application of heat to increase vapor pressure inside plastic pellets and to force entrapped moisture to the pellet surface is said to cut hygroscopic resin drying times down to as little as 30 minutes. The Speedryer uses a counter flow of heated air to strip moisture from the pellet and jettison it out to the ambient atmosphere leaving dry plastic behind. Speedryer users attest that the system has corrected moisture problems, lowered material degradation, and increased processing windows, particularly with nylons.
