Abstract: The invention relates to a method for dry fractionation of fatty substances by a counter current dry fractionation operation, comprising at least two dry fractional crystallization treatments;a first dry fractional crystallization treatment comprising the steps of:1a) dry fractionating by crystallization the fatty substances into a higher melting first stearin fraction and a lower melting first olein fraction;1b) separating the first stearin fraction from the first olein fraction by membrane filter pressing; and1c) feeding the separated first olein fraction to a second dry fractional recrystallization treatment; anda second dry fractional crystallization treatment comprising the steps of:2a) dry fractionating by crystallization the first olein fraction into a higher melting second stearin fraction and a lower melting second olein fraction;2b) separating the second stearin fraction from the second olein fraction by membrane filter pressing; and2c) feeding the separated second stearin fraction to the first dry

Abstract: The process is a discontinuous process wherein the oil is subjected to interesterification in a discrete charge and comprises bringing together streams comprising respectively at least a portion of a charge of triglyceride oil and catalyst solution of water, alkali metal, hydroxide and glycerol, homogenizing the mixture, reducing its water content, and interesterifying. The process can be performed either as a semi-continuous process or as a circulatory batch process. Preferably the homogenization and drying steps are combined and are performed by passage through a spray drying nozzle. The spray drying nozzle preferably sprays the mixture directly into the reaction vessel.

Abstract: The process is a continuous process and comprises bringing together streams comprising a triglyceride oil and a catalyst solution of water, sodium hydroxide and glycerine respectively, homogenizing the mixture, reducing its water content, and interesterifying. Preferably the homogenization and drying steps take place consecutively and are combined and are performed by passage through a spray drying nozzle. The efficiency of the homogenization and drying steps allows the interesterifying step to take place in about 4 minutes and thus permit operation of the process in a continuous manner.
