2014 petfood industry extrusion round-up

Petfood safety, innovation the key targets for industry experts

Every year brings unique challenges to the extrusion segment of the petfood industry, and 2014 has been no different. Two key factors, brought on by significant industry events, are foremost on expert minds as the year closes: petfood safety and innovation.

Coperion (www.coperionktron.com) is meeting the food safety challenge through ease of machinery cleaning. For example, the process sections of the Coperion ZSK extruders consist of several barrels in which the screws co-rotate. The closely intermeshing, self-wiping screws prevent stagnant zones along the whole length of the process section, for constantly high conveying and optimum self-cleaning. The recently introduced Coperion K-Tron Sanitary Filter Receiver has a top entry and custom-engineered side access filter assembly that allows for high efficiencies, with minimal degradation of the product due to decreased can velocities, and extremely high access to all internal areas of the receiver for cleaning.

Bühler Aeroglide (www.buhlergroup.com/drying) is another company with petfood safety on its radar. “The…
