Indirect Drying Drums Optimum drying of solvent-based products with Indirect Drying Drums Indirect Drying Drums use hot air as a convective drying technique. This enables significant savings in primary energy and fuel by using the preheated, dust-free and dry cooler exhaust air. The reduced oxygen atmosphere makes it particularly suitable for use in drying products containing solvents. Indirect Drying Drums are particularly suitable for non-adherent, easy-flowing and fine-grained bulk materials such as zeolite, gypsum, silicate powder and titanium dioxide. Benefits: High efficiency: Low investment costs for exhaust air filters, low electrical energy requirements due to low process air volumes. High safety: A reduced oxygen atmosphere is possible to avoid product oxidation or to avoid/reduce harmful exhaust gas flows. Minimal process costs: No filter systems necessary for after-treatment of the warm cooler exhaust air. Robust design: Robust and long-lasting construction.
