Counterflow pellet coolers

Optimize temperature control and enhance product integrity in your feed production line with precise and efficient cooling technology, designed to handle high-speed operations for granular and powdered products.

Cools and Conditions Pellets and Extrudates

The OM Series Counterflow Pellet Coolers from Ottevanger Milling Engineers offer robust and efficient cooling for a variety of feed and processing applications. Designed for high-speed, continuous operation, these coolers efficiently reduce the temperature of pellets and extrudates by utilizing a counterflow air movement system. This system cools products on their journey from the pellet mill to the discharge hopper, preventing thermal shock and preserving pellet integrity. Commonly used in aqua feed, pet food, and oilseed processing, these coolers handle capacities up to 30 tons per hour. Integrated seamlessly into existing lines, their PLC control provides intuitive operation. Constructed from durable materials, they offer long-term operational reliability, with customizable discharge systems to fit specific needs.

Benefits
