Eco-Refine - Model ATFD -Agitated Thin Film Dryer
We recommend the DRY CONTROL FILM ROTOR: We have special precision designed centrifugally balanced blade that has higher e?ciency compared with other types of dryers. The balance and weighing cause the blade to ride truer and quieter on the ?lm and give higher product quality due to heavily reducing entrainment. The advanced wipers geometry reduce splashing to a minimum, which means less wet salt gets into rotor blade slots.
The discharge system has also been enhanced in recent years and can be discussed personally. It is proprietary but not necessarily con?dential. Instead of providing any valves to discharge system we recommend maximum up time or directly trolley to removes the bottom products.
HOW ATFD WORK
Wet product in form of slurry (range from 30 to 50 % w/w) fed through the inlet nozzle is conveyed gradually by the rotor blades along the heated dryer wall in a thin ?lm (With the help of steam or Hot Oil or any heating media), normally in millimeters thick, preventing buildup and continuously exposing every particle of the product to the heated surface. Vapors pass counter currently to the product ?ow and exit the dryer through the feed nozzle, as con?gured above. Moisture levels from a few tenths of a percent up to 5%+ can be achieved. Residence time is typically controlled as per requirement.
