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. rst optimized. Oleic sunower seeds were crushed and 80% of. the oil
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%.

(NF V03-905) was 52%. The dry matter content at storage was 93.7% (NF V03-903). The oil content of the oleic sunflower seeds used in the second set of tests was 50.9% in relation to the dry matter.
An increase of oil extraction yield was observed as the reversed screw elements were moved with increased spacing between two elements and with smaller pitch elements. In addition, oil extraction yield increased as barrel temperature, screw speed and feed rate were decreased. Highest oil extraction yield (85%) with best cake meal quality

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 mechanical screw press. Seventy-five percent of the oil of sunflower seeds can be extracted by crushing, and the fatty cake then contains about 15% of oil. The oil levels remaining in the cake can
A new application of twin-screw extruder as a machine to conduct a thermo-mechanical pressing and a solvent extraction of sunflower oil in a single step and in a continuous mode was studied.
Extraction of sunflower oil by twin screw extruder: Screw
The screw configuration and the operating conditions had an important influence on the oil extraction yield, the energy input and the quality of oil extracted during the extrusion of sunflower seeds. Higher oil extraction yield and specific mechanical energy were reached as the reversed screw elements were moved with increased spacing between
The oil yield for the aqueous extraction stage was calculated according to the following formula: RL2 = QF2 × TL2 × LL2 × 100, ′ ×L QC1 C1 459 Fig. 3 – Schematic modular barrel and screw congurations of the Clextral BC 45 twin-screw extruder used for aqueous extraction of residual oil from press cake A (proles 3 and 4), and press

Comparison between the Clextral BC 45 twin-screw extruder and the Waring blender mixer The twin-screw extruder showed a better aqueous oil extraction than the Waring blender. The best RL obtained with the twin-screw extrusion technology was approximately 55% (Table 4; trial 5), 34.5% higher than what was obtained from the Waring blender.
- What is industrial pressing of oilseeds?
- Industrial pressing of oilseeds is realized using continuous screw presses. The presses are fed with crude or pre-treated seeds. Types of pre-treatments (thermal pre-treatment, size reduction, mechanical sieving, etc.) differ for various seed species (Carr 1997). Each type of seed pre-treatment provides its own advantages.
- Does a twin-screw extruder reduce oil recovery?
- As an illustration, a decrease in oil recovery from 82 to 62% was found during the thermomechanical pressing of sunflower seeds using a twin-screw extruder of increasing volume and an increased feed rate from 14 to 22 kg/h, respectively, while maintaining the raw material characteristics and operating conditions (Dufaure et al., 1999a).
- How to extract oleaginous seeds without solvent?
- 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).
- What is a screw press expeller?
- The expellers (named after the first screw press founded by Anderson in 1902) are the screw presses most often encountered in the industry. They consist of a screw rotating in a horizontal perforated barrel formed by regularly spaced metal bars (this space can vary from 0.5 to 0.1 mm); the oil flows along the barrel.
