Heat waste recovery in rotary dryers

The dryer incorporates a waste heat recovery system providing hot water for other process uses. Gases discharged from the dryer are passed through a cyclone to remove dust and then cooled down through a shell and tube condenser. Up to 50% of the air flow is then recycled back to the dryer and the remainder

    Steam rotary dryers | IDRECO S.r.l

    In Steam Rotary Dryers steam is used as heating medium: steam is conveyed inside a series of tubes. The heat transfer occurs from the tubes wall to the product by radiation and conduction even if the temperature of metal surfaces is generally low, as a result of the saturation temperature of steam which depends on its inlet pressure

    Direct heat dryers, where the heat transfer occurs by convection of hot air or gas inside a rotary cylinder, are the most common and used thermal dryers. Hot air or gas flows through the cylinder and then transfers to the product, warming it and evaporating the water, therefore temperature of heating media inside the dryer is the mean parameter
