Deodorizer is multi-compartment vertical vessel, where each and every tray are specially designed which Ensures uniform distillation of odoriferous substances. Oils overflow from specially designed trays to 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 countercurrent 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. VAPORS SCRUBBING The volatile matters consisting of free fatty acid and other odoriferous substances stripped from the deodorizer are led to the vapour scrubber located at the outside of the deodorizing column. In the scrubber, volatile material rises through the bed of pall rings and meets liquid fatty acid sprayed from the top. Vapours are condensed, cooled, and then recalculated to condensed fresh vapours. Excess distillate collected is led to the storage tank, whenever high level reached in storage space below the scrubber. Fatty acid scrubber is specially designed for minimum carryover of fatty materials, to the vacuum system .
