Fraktionierung von Palmöl durch selektive Kristallisation an einer gekühlten Fläche

Fractionation of Palm Oil by Selective Crystallization on a Chilled Surface A new process for the fractionation of palm oil was studied, which enables the crystallization and separation of the components in a single processing step. The higher melting fraction is selectively crystallized on a chilled surface, while the lower melting fraction is enriched in the liquid. The influence of processing parameters on the separation was studied experimentally. It was found that the extent of separation is determined by the rate of growth of the phase interface, thickness of the boundary layer between the phase boundary and liquid, and time of fractionation. Optimum conditions are given for all parameters.
