continuous deacidification deodorization

The Deodoriser is a double shell design with 5 stages. The oil is heated and drops to the prestripping section with open steam sparging. The carrier steam takes all the volatile components like fatty acid, tocopherols sterols etc. away. These are recovered in the fatty acid condensing system. The prestripping is done by mamuth pumps, the oil then flows to deodorizing section where steam sparging at full deodorizer vacuum takes place to yield a high quality heat bleached oil. Here complete deodorization of oils take place as residence time is high, the hot oil then enters a heat exchanger.
