ATFD
Agitated Thin Film Dryer (ATFD) is a very modernized and a dynamic equipment.
This shall be used majorly for product layer concentrations and in ETP (Effluent treatment plants).
The working principle of this equipment is vaporization under vacuum and atmospheric condition.
Sizes Available in design
Optimum overall heat transfer co-efficient for design.
Design of ATFD will be done on 8 kg/cm2.
Operation of ATFD will be done majorly on 6 kg/cm2.
Inlet TDS to ATFD will be 35%
Dry Powder with 5-10 % Moisture will be collected from bottom of ATFD
Why VZLD ATFD
Trouble free operation
Design as per ASME
Investment casting blades are use as a scrapper
Heavy duty SKF bearing of 32 series will be used for top support
Minimum wash water required for CIP of ATFD.
Damaged blades can be easily replaceable
Graphite bush is used as a bottom support which will given more life as compare to bearing and Teflon bush
Less power consumption
