Energy-slashing dryers

A range of dryers employing a rotor wheel honeycomb structure promises significant energy savings over traditional technologies, according to its Italian supplier, Vismec Srl (Camposampiero, Italy).

The Dryplus series of dryers guarantee 40% less energy consumption compared with twin-tower desiccant drying technology, according to Carlo Bonaventura, operation manager at Vismec. “They also feature an auto set-up mode where the operators need only input resin type and desired output.”

Dryplus dryers also allow dew point to be set freely in order to reduce the stress on the polymer and to optimize viscosity in processing equipment. Furthermore, no water is required with the plug-and-play dryer range, and the desiccant operating life is five years.

In addition, Dryplus dryers feature a Safety Loading System that prevents the use of material before it has been properly dried. A countdown timer on the display indicates when the material is dry and ready to process.

The dryers can also be fitted with an integrated feeding system to convey undried material to the drying hopper and then dried material to the processing machine. In this case, a Material Protection Management (MPM) can constantly monitor the throughput of dried material and automatically adjust the airflow. If the processing machine stops due to a fault, for example, the MPM system recognizes this and the Dryplus automatically recognizes this and goes into standby mode. —Stephen Moore
