(PDF) A Twin-screw extruder for oil
Nevertheless, recent technological advances have highlighted the interest of twin-screw extrusion, which favours both the obtaining of a high-quality oil as well as a co-valorisation of the cake

The oil levels remaining in the cake can be reduced to less than 2% by solvent extraction. However, the crude oil has to be refined as it contains many impurities and approximately 600 ppm phosphorus. A new process, in which sunflower seeds are pressed in a twin-screw extruder, is examined here. The screw profile was first optimized.

Lipids are traditionally removed from seeds by mechanical crushing and solvent extraction. During the mechanical crushing process the oilseed is cleaned, cracked, flaked, and cooked before entering a...

A new process, in which sunflower seeds are pressed in a twin-screw extruder, is examined here. The screw profile was first optimized. Oleic sunflower seeds were crushed and 80% of the oil was removed. The resultant oil was of good quality, with acid numbers below 2 mg KOH/g of oil and total phosphorus contents of about 100 ppm.
Extraction of sunflower oil by twin screw extruder: screw
The objective of this study was to investigate the screw configuration allowing oil extraction from sunflower seeds with a twin-screw extruder. Experiments were conducted using a co-rotating twin-screw extruder. Five screw profiles were examined to define the best performance (oil extraction yield,

Twin-screw extrusion technology for vegetable oil extraction
The twin-screw press operated at a feeding rate of 50?8 kg/h and attained a high oil recovery of 94% for dehulled sunflower seeds. The process was compared to a lab-scale single-screw pressing operation with a feed rate of 19?3 kg/h, which resulted in a low oil recovery of 20%.
