Industrially, seed oil recovery is achieved by a sequential process of mechanical expression and hexane extraction. Mechanical expression is generally considered as the most efficient technique to recover virgin oil of high quality, but it only allows a partial defatting of the seeds. Therefore, the resulting press cake is usually defatted by

The oil extraction by mechanical pressing is the most common method for continuous treatment of oleaginous seeds without solvent. Different types of presses can be used depending on the purpose (expeller, expander, and twin-screw extruder) and on the capacity range (3 kg h鈭? to 150 t day鈭?). At the laboratory scale, many authors have highlighted the effect of operating parameters (screw
