What are the different processing techniques of oilseeds?
Understanding of various processing techniques of oilseeds is very important. Pre-treatments like cleaning, dehulling, decortications, flaking and heat treatments assist to enhance the recovery and quality of oil during processing. Oil extraction methods including ghanies, hydraulic press, screw press and solvent extraction are discussed in detail.
How is crude oil extracted from hydraulic press and screw press?
The crude oil obtained from hydraulic press and screw press needs filtration, which is performed using filter press (Fig. 12.6 ). The filter press contains papers or cloth as filter, which is supported by vertical plates and fixed on frames.
How to extract groundnut oil?
