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.
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.
