20130287925 | PHYSICAL REFINING OF TRIGLYCERIDE OILS AND FATS - A process for the physical refining of edible oils and fats, said process comprising three consecutive stages, whereby in a first stage at least 60% by weight of the volatiles are evaporated in a flash vessel, in a second stage some residual volatiles are evaporated by countercurrent steam stripping using a packed column ( | 10-31-2013 |
20100240917 | Enzymatic oil recuperation process - A process for the recuperation of acylglycerols or acylglycerols containing free fatty acids from gums, present as aqueous emulsions, said gums being obtained by subjecting triglyceride oil to one or more degumming processes, said recuperation process comprising the steps of: subjecting said gums to enzymatic hydrolysis catalysed by one or more enzymes with phospholipase activity; allowing said gums to separate into two or more phases, said two or more phases including at least an oily phase and an aqueous phase; and recuperating said oily phase comprising acylglycerols or acylglycerols containing free fatty acids; wherein said enzymatic hydrolysis is accelerated by adding at least part of the one or more enzymes with phospholipase activity to at least part of the water used in the recuperation and/or at least one degumming process; and/or at least part of said triglyceride oils treated in said degumming process; and/or by facilitating mixing at least part of said one or more enzymes with phospholipase activity into said gums by increasing the triglyceride oil content of said gums; and an oil obtained by this process. | 09-23-2010 |
20090246339 | CRYSTALLIZATION APPARATUS AND PROCESS FOR MOLTEN FATS - Methods and apparatus are described for the production of a crystal slurry during the crystallization step of fractionation processes of edible oils and fats and related oil derivatives. The crystallization process for edible oil and fats is carried out in a crystallizer with stationary heat exchange elements, wherein the contents of said crystallizer are made to move along said heat exchange elements in an oscillatory manner without the use of an internal agitator. The crystallizer for edible oil and fats with stationary heat exchange elements is also described. | 10-01-2009 |
20090158640 | PROCESS FOR PRODUCING BIODIESEL WITH IMPROVED FILTRATION CHARACTERISTICS AND BIODIESEL THUS PRODUCED - A process for the production and purification of fatty acid esters of lower alkyl alcohols with improved filtration characteristics comprising the steps of: a) transesterifying a mixture of fatty acid esters of glycerol with a lower alkyl alcohol while using an alkaline catalyst; b) separating the reaction mixture resulting from step (a) into a glycerol phase and a fatty acid lower alkyl ester phase; c) inactivating the catalytic intermediates present in said fatty acid lower alkyl ester phase; d) removing the lower alkyl alcohol from the mixture resulting from step (c) by evaporation at reduced pressure to a value of less than 2% by weight; e) treating the evaporation residue resulting from step (d) with water; and f) isolating the fatty acid esters of lower alcohols by drying the product resulting from step (e); and biodiesel containing FAME produced according to this process. | 06-25-2009 |
