Whether manufacturing in a batch process or in higher volumes via continuous methods, Coperion and Coperion K-Tron feeders and material handling equipment as well as Coperion high efficiency extruders are used throughout the dry pet food and pet treat manufacturing processes. Screw feeders (both volumetric and loss-in-weight), liquid loss-in-weight, and weigh belt feeders are used for metering and highly accurate feeding of ingredients into mixers (batch or continuous) and extruders as well as portioning end products for the packaging line. In addition, Coperion pneumatic conveying systems and components are used for the transfer of dry powder materials, such as grains, premixes, vitamins and even probiotics. Finally, the use of the Coperion ZSK MEGAvolume PLUS twin screw extruder delivers an extremely high product output for optimal efficiency in dry pet food and treat production.
