Working principle of hollow paddle dryer:
Thermal drying is an intermediate sludge treatment process that consists of evaporating the water in the sludge. It significantly reduces the volume and weight of the sludge so that it is easier to recover.
The hollow paddle dryer is an indirect heating type composed of the casing with a jacket and shaft with a disc that contains steam or other heating media, Hollow paddle dryer (also called disc dryer) can dry all kinds of animal waste in an atmosphere controlled environment with multipoint thermal control, such as poultry entrails, municipal sludge, textile sludge, catering sludge, chemical sludge, etc.
The paddle (discs) cover 80% of the total heating surface.
