Abstract. 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

Hydraulic pressing of oilseeds: Experimental
The possibility of using the oil‐point and compression tests for evaluation of dried rapeseeds processability was examined. Seeds of initial moisture 10, 14, 18 and 22% (w/w) were dried at 60, 80, 100 and 120°C to a final moisture of 6·5% (w/w).

The use of pump pressure in filtration represents the simplest hydraulic deliquoring process. In expression operations, pistons, membranes, rollers or belts are employed to squeeze the particulate cake after filtration is complete.

Heavy metals including Lead (Pb), Cadmium (Cd), Arsenic (As) and Aluminium (Al) were analysed in oilseeds, noodles, tea leaves and their processed or cooked products to study the effects of food processing methods on migration of heavy metals. The heavy metals were determined with ICP-MS and ICP-OES following microwave-assisted acid digestion.
- Can a hydraulic laboratory press be used to press oilseeds?
- In this paper are presented the results obtained from oilseeds pressing, using a hydraulic laboratory press. Based on the experiments, the material balance was made, taking into account the piston speed and its applied force, for both types of oilseeds used (sunflower seeds and rapeseeds).
- Which mathematical models are used in oilseed expression?
- Mathematical models previously used in oilseed expression are either empirical (Fasina and Ajibola 1990), based on the nature of cell structures (Lanoisellé et al., 1996)) or Terzagi type models (Mrema and McNulty, 1985, Shirato et al., 1986). The first type is limited to specific seeds and equipment on which the measurements were done.
- Do hydraulic press parameters affect crude palm oil yield?
- Ajiboye Osunleke Oyebamiji B.E An investigation was carried out on the effect of hydraulic press parameters such as press cage diameter (D) (80, 120, and 150 mm) and wall pore diameter (H) (4, 6, and 10 mm) and expression pressure (P) on crude palm oil yield.
- What is oil extraction method?
- One of the most usually method for oil extraction is the mechanical expression, also known as pressing. Pressing represents the operation which separates the oil from the oleaginous material (solid-liquid mixture), under the action of external forces, resulting crude oil and cake.
- How a seed press is used in agriculture & food industry?
- DESIGNED TO AGRICULTURE AND FOOD INDUSTRY –INMA from Bucharest, Romania. For the experiments, 120 g of seeds was placed in the press chamber, after which the piston was lowered on top of the seeds. With the help of electromechanical universal testing machine, the piston starts compressing the sample seeds. For each type of seeds,
- Does hydraulic extraction improve oil extraction efficiency?
- CONCLUSIONS AND FUTURE WORK Many researches focused on the hydraulic pressing, one of the most utilized methods of oil extraction, in order to improve the extraction efficiency. Hydraulic extraction is influenced from various parameters, asit results from the researches, one of the most important being the pressing time.
