    The combined exhaust air volume produced by sugar drying and cooling can thus be reduced dramatically, resulting in far lower costs for exhaust air dedusting equipment, and smaller exhaust-air fans with lower power requirements. This energy saving effect makes the combined drum dryer fluidized-bed cooler system a highly energy efficient option.
