Custom China KJG Series Sewage Stainless Steel Sludge Blade Dryer
Product Description:
The Hollow Paddle Dryer has a metal wall which separates the
process mass from the heat source (steam or hot oil). High thermal
efficiency is obtained because the heat from the thermal medium
goes directly into the process mass. As the material comes into
contact with the heated through and agitators, the process mass is
heated via conduction. With an insulated dryer, very little heat is
lost. To evaporate 1kg of water only requires about 1.2kg of steam
for slurry materials. Exhaust gas is minimal and at a low
temperature. Therefore, the volume of non-condensable gas from the
dryer, which might require treatment, is minimal.
Working Principle
The cylinder is a jacket structure in which hot steam circulates
inside. During operation, water vapor is introduced into the jacket, hollow
shaft, and blade to provide the heat required for drying; a very
small amount of air is introduced into the dryer and used as a
carrier for the steam (or organic steam) that evaporates during
drying; the material enters the machine from the feed port, and is
conveyed by the hollow blade to the discharge port for discharging.
The material is heated and evaporated by the hollow blade and the
jacket during the conveying process to be dried. The heat transfer
surface of the wedge blade has a self-cleaning function. The
relative motion between the particles and the wedge surface
produces a washing effect that washes away the adhering material on
the surface of the blade, which allows the material to have a long
residence time and a high fill factor.
