PEMAC offers a wide range of batch & continuous dry fractionation plants. Most of the natural oils & fats have only a limited application in their original forms as a consequence of their specific chemical composition. In order to widen there uses the oils goes through Varity of modifications, fractionation is one of them. Fractionation is the fully reversible modification process.
It is basically a thermo chemical separation process in which a multi component mixture is physically separated in to two or more fractions with distinct physical & chemical properties that can be based on a difference in solidification, solubility or different compounds.
PEMAC’s dry fractionation plant is a custom design to allow you to achieve selective crystallization of different triglycerides in edible oil. This is plant you can count onproducing stable & filterable crystals giving you a product fit to your standards and quality requirements.
PEMAC’s Dry Fractionation System is designed to process crude, pre-treated or RBD palm oil. The process is divided in few steps as below.

IV is a measurable degree of instauration. Duringcrystallization more saturated &. hence higher melting triglycerides concentrate in to solid phase, whereas the olein fractionsbecomes enriched in more unsaturatedtriglycerides. The change in IV also measurable forseparation efficiency as it can be used to quantity theseparation.
