Deodorizer is multi-compartment vertical vessel, where each tray are specially designed which Ensures uniform distillation of odoriferous substances. Oil is overflows from tray to tray. Specially designed trays provide sufficient mass transfer surface for effective removal of volatile matters. Flow control system at the outlet of the deodorizer, ensures the maintenance of required level at the bottom tray. The steam used for stripping off volatile matters in the oil is distributed evenly and intensively, the steam meets the deodorized oil. Stripped off the volatile matter and rises through the vacuum. Stripping the volatile matter from the oil. The counter- current flow of steam and oil like this in specially designed trays lower steam consumption, than the conventional deodorizers. The deodorized oil leaving regenerative heat exchanger and finally cooled by water in heat exchanger finally this oil is passed through the alternatively operating set of polishing filters.
