Sludge Dryer

Sewage and waste water sludge drying

? Avoid high-viscosity state of the sludge (water content 60~40%) by allowing drying even without a recycle structure

? Relatively less mechanical abrasion and sealed-structure contains undesirable odor

? Food waste drying

? Indirect drying type minimizes gas from leaking outwards when drying food wastes, and minimizes complaints concerning odor.

Adhesion of drying wastes is relatively small, enabling wastes with a limited amount of viscosity to be dried.

Advantages:? Externally: composed of 2 or more axes for high-temperature steam inflow and for jacket and paddle, and an inlet on the upper side for drying-materials and, also an extraction point and a gas discharge component for discharging exhaust gas.

? Internally: 2 or more axes for the inflow of high-temperature steam has attached crescent-shaped paddles which rotate, allowing contact with input wastes for drying It also acts as screw, and transports the wastes along the structure.

? High-temperature steam enters from the paddle axis, and delivered to the inner side of the paddle.

? As the paddle rotates, the wastes get in contact with the slanted walls, and the moisture vaporizes.

? Drying wastes are transferred by the slanted plane of the paddle.

? Drying wastes do not stick due to the slanted plane of the paddle.
