884 A New Twin-Screw Press Design for Oil Extraction
Dehulled se are sflaked from dehulled sunflower se with d atwin,crew pr iss to 0.35 mm to rupture cell structures and free the oil, highly efficient. steam-cooked and partially dried, then expressed at 80-105°C and 4-7% moisture until 15-18% oil remains. KEYWORDS: Dehulled sunflower seeds, oil expression, The twin,screw 3-4 mm thick presscake
Transport of material in a single-screw press depends mainly on friction between the material and the barrel’s inner surface and the screw surface during screw rotation. Thus, a solid core component, like seed hulls, is often necessary to produce the fraction. This sometimes causes excess frictional heat, large energy consumption and oil deterioration. Furthermore, if single-screw presses
Twin-screw extruder for oil processing of sunflower seeds
This study showed that the new application of twin-screw extruder as a machine to conduct simultaneously thermo-mechanical pressing and solvent extraction of sunflower oil in a single step and in a continuous mode have been successfully carried out, and was a promising alternative technology for oil processing of sunflower seeds.
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 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 pressure on screw was determined & applied in the created meshed design in Ansys. From the achieved stress analysis it can be concluded that the screw used in this project is within safety
Twin-screw extrusion technology for vegetable oil extraction
Twin-screw extrusion technology exhibits promising perspectives in the field of vegetable oil extraction, especially when integrating several extraction stages in a single extruder passage. However, extensive additional research is crucial in order to further develop these processes and assess their industrial feasibility.
A twin-screw press (screw diameter=136 mm, length/diameter=6.5, screw speed 15–100 rpm, feed rate=50–150 kg/h) was designed with partially intermeshing and counter-rotating screws and was tested on dehulled sunflower seed. The results were compared to a single-screw lab-scale press. Dehulled sun-flower seed (wt, 6.0%; oil, 58.6%) without
- What percentage of oil is used in sunflower seeds?
- To be specific, oil-used sunflower seeds contain 45%~60% of the oil which is suitable for the pre-pressing and leaching method: In the 1 st, the raw seeds are pre-squeezed by means of a continuous screw press.
- What is the oil extraction ratio of oil palm screw press?
- … Plate 1: Side View of the Oil Palm Screw Press (Adetola et al., 2012) Results of performance test showed that the highest oil extraction ratio (OER) of 17.90% and oil extraction efficiency (OEE) of 79.56% were obtained at the sterilization time of 60 min, digestion time of 10 min and screw speed of 10 rpm (Adetola et al., 2012).
- What is a professional sunflower seed oil press?
- The professional sunflower seed oil press is ZY24 (202-3) continuous oil extraction machine. In small and medium-sized vegetable oil plant, ZY24 (202-3) continuous pre-pressing machine is a popular equipment for pre-squeezing and leaching process.
- How is sunflower seed oil extracted?
- Sunflower seed oil is extracted from oil-type sunflower seed by the mechanical pre-pressing method with subsequent hexane extraction of the remaining oil in the meal.
