Working principle

Counterflow cooling is the most efficient process for granular products and meal. The air flows in the opposite direction to the product which means that the product is gradually cooled on its way from pellet-mill to discharge hopper. The air is gradually warmed on its way from air inlet to cooler exhaust, thus preventing pellet damage due to a temperature shock.


Depending on the specific application special discharge systems are available.
