Twin-screw extruder for oil processing of sunflower seeds
In addition, oil extraction yield increased as screw rotation speed and feed rate were simultaneously increased to Q S /S S ratio of 0.2. Highest oil extraction yield (98%) with best cake meal quality (residual oil content lower than 3%) was obtained under screw rotation speed of 185 rpm, feed rate of 30 kg/h, and solvent-to-solid ratio of 0.55
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

Furthermore, an investigation of continuous oil extraction using an extruder divided into two zones, (i) twin-screw zone, which was built from two co-rotating and co-penetrating screws and (ii) double single-screw zone, which was constructed from two co-rotating single-screws, increased oil yield up to 90% with residual oil content in cake meal
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−1 to 150 t day−1). At the laboratory scale, many authors have highlighted the effect of operating parameters (screw
Aqueous extraction of residual oil from sunflower press cake
When oleic sunflower oil is expressed, a longer reversed pitch screw improves oil yield, which can rise 80% in the optimized operating conditions (LacazeDufaure et al., 1999a ). When two reversed pitch screws are used, the oil yield increases with the distance between them and with the decrease of the screw pitch (Amalia Kartika et al., 2005a
The twin-screw press operated at a feeding rate of 50–58 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 19–23 kg/h, which resulted in a low oil recovery of 20%.
A Twin-screw extruder for oil extraction: I. Direct
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
corotating twin-screw extruder (BC 45, Clextral-France) was carried out in this study. Five screw profiles were examined to define the best performance (oil extraction yield and oil quality) by studying the influence of operating conditions: temperature pressing, screw rotation speed and seed input flow rate. The position and the space
Oil extraction of oleic sunflower seeds by twin screw
Oil extraction yield (standard ISO 3657), is the amount of alkali necessary The position of BB, DM and CF elements and the to saponify a definite quantity of the oil; (iv) the spacing between two elements affected generally the phosphorus content, expressed in mg of phosphorus oil extraction yield R and Ro (Fig. 3). High oil extraction per kg
Experiments were conducted using a co-rotating twin-screw extruder. Five screw profiles were examined to define the best performance (oil extraction yield, specific mechanical energy and oil
