Counterflow is not only the most efficient method to transfer heat, but also moisture. When combined with the recovery and re-use of energy from the cooler and the lower dryer decks, this means that counterflow dryers can achieve energy savings of at least 24% (*), when compared to best available alternatives.

When replacing existing dryers, savings of up to 50% have been achieved. For most extruded petfood or aquafeed the energy requirement for drying is below 2600 kJ per liter of evaporated water.
