Powder dryer heaters are steam heaters used in the production of hot air which is utilized in spray drying machines. They are widely used in the production of powdered milk and other such food products that undergo powder drying. Steam pressure is available up to 3MPa. The powder dryer heaters can also be equipped with high efficiency HEPA filters to remove foreign particles.
Used widely for drying applications such as spray-drying of powdered milk, powdered food seasoning and herbal medicines, as well as for drying compounds such as sucrose and starch.
Air flows through a pre-filter and an intermediate filter before it enters the air heater to prevent entry of foreign material.
To prevent adherence of foreign matter, the connection gas side is polished with a buff grinder (except for the fin tubes).
