Dry fractionation, also known as crystallization from the melt, is fractional crystallization in its simplest form. The features of the technology allow it to be used for the production of commodity fats. Dry fractionation has long been regarded as an unpredictable, tedious and labor-intensive process. However, the relatively cheap dry ...

Layer melt crystallization was applied for the dry fractionation of multi-component mixtures using coconut oil as a model substance. The aim of the experiments was to optimize the crystallization parameters (e.g. crystallization temperature, melt temperature, cooling rate, agitation speed) in order to obtain the solid fraction with a higher melting temperature and solid fat properties.

Palm oil fractionation goes through the control of palm oil cooling and crystallization to make separation of palm oil into low melting point liquid (soft fat) and high melting solid (sterin). Fractionation of palm oil can be divided into three fractions: stearin (palmstearine), soft fat (palmolein) and middle section (palmmidfraction).
