Abstract: The present invention relates to a semi-continuous deodorizer comprising at least one stripping section, which stripping section comprises a feed buffer tray for liquids, a liquid flow regulating means, a liquid distributor, a structured packing, and a receiver tray, wherein the regulating means are regulating the liquid flow from the feed buffer tray to the distributor to distribute the flow of liquid over the structured packing. The liquid is in the packing contacted in counter-current flow to an already once-used stripping agent which is recovered from one of more of the trays installed in the apparatus. The invention relates further to a method for refining fats and oils in a semi-continuous deodorizer, a method for re-using stripping agent in a semi-continuous deodorizer, segregating the recovered distillate into high purity types matching the feed type, and a use of the semi-continuous deodorizer.
