Rapeseed oil production has been increasing globally over the last couple of decades. The rapeseed oil and its by-product, the rapeseed meal, are actively used not only for human and livestock consumption, but also in major industrial applications. In an industrial scale, the rapeseed oil production involves several steps of preparation of seeds for preliminary pressing, followed by several steps of extraction of oil. There has also been an interest in the small scale oil production for food consumption and for fuel purposes. In this regard, the educational institution IUT Nancy-Brabois created a research project for small scale oil production using the screw press Farmet UNO FM. The thesis work was based on this research project, which was implemented during the practical work in spring 2019 in IUT Nancy-Brabois.
The aim of the work was to define the optimal combination of press nozzle of diameters 6, 8, 10 mm with frequency of 30, 50, 70 Hz of the screw press to obtain the high production of rapeseed oil and least production of oilcake. The obtained oil was subjected to centrifuge filtration. The oil from oilcakes with diameters 6 and 10 mm was extracted with propan-2-ol (C3H8O) solvent. The soap was produced from mixture of obtained rapeseed oil with store-bought olive oil, followed by pH analysis. The biodiesel was produced from obtained rapeseed oil, followed by analytical chromatography analysis and viscosity testing. Both viscosities of biodiesel and rapeseed oil were compared.
The results showed the highest oil production was achieved with combination of 6 mm press nozzle and 30 Hz frequency. Pressing 38,65% of oil and 60,83% of oilcake per 500 g of seeds. The centrifuge filtration ran during 5 min and 10 min showed almost the same filtrated residue of 12,35 g and 12,57 g respectively. Therefore the set-up of 5 min was determined to be the most time efficient. The solvent extraction showed the 6 mm diameter oilcake contained the least amount of oil. The soap was produced with skin-safe pH of 8,5. The biodiesel was successfully produced with the viscosity close to standards. Analytical chromatography analysis indicated the formation of biodiesel. The obtained results were accepted and approved by IUT Nancy-Brabois and will be used as a base in future laboratory works and research projects.
