The Counterflow dryer operates by sucking hot air through one, two or three product beds which are each variable in depth. New product is continuously fed through the inlet valve, while the ‘swivel valve’ discharger ensures smooth discharging of dried product to the next drying deck or into the hopper.
Ottevanger Milling Engineers is making all the advantages of counterflow available to the drying of petfood, fish feed etc.
