Mustard Solvent Extraction Processes - An Insight
The Oil cakes obtained from expellers are cleaned to remove impurities like husk,
stone particles etc, through pre cleaner and de stoner which are further fed to the Cracker Breaker to make small pieces.
These cakes are then fed to the solvent extractor. In the solvent extractor food
grade hexane is sprayed through the cake to extract the oil content (7 to 9%) out of the cake.
This wet DOC is further fed to De solventiser Toaster to evaporate hexane
particles and oil particles.
Output of the toaster section at bottom is De Oil Cake and is separately collected,
conveyed and packed in Gunny Bag or PP bag.
Evaporated particles/ Miscella (mixture of oil and Hexane) is fed to distillation and
recuperation section to depart oil and hexane.
This recovered hexane is recycled in the process.
Solvent extracted raw grade oil is required to go through degumming and refining
to produce refined oil.
Crude oils having relatively high levels of phosphatides may be degummed prior to
The process generally involves treating the crude oil with a limited amount of
water to hydrate the phosphatides and make them separable by centrifugation.
