Coperion system uses hot air for degassing

EcoFresh technology is available in single- and twin-silo versions, and a design for batch processes.

EcoFresh Coperion’s degassing system uses hot air to deodorize recycled plastics in a silo. Coperion offers both a single-silo and twin-silo design, as well as a design for batch processes. Coperion designed both the single- and twin-silo technologies for continuous operation. The twin-silo technology uses one silo to heat and deodorize the granulate and another to cool the granulate with cold air.

What’s new? The technology, which Coperion introduced at the K show.

Benefits Effective deodorization, resulting in recycled plastics comparable to new plastic in terms of odor quality. Also, both the single-silo and twin-silo technologies are energy-efficient. The single-silo technology uses two heat exchangers so heating, degassing and cooling can take place in one unit, while the twin-silo technology uses all the process heat from the cooler to heat the pellets in the deodorization unit.
