The study of rapeseed oil production technology of reduced macronutrients content as an engine fuel

The evaluation of rapeseed oil production technology of reduced macronutrients content was executed on the specially made experimental production line. The scope of the study included the process of rape seed pressing and oil refining. Performance screw press FARMET DUO, level of oil yield and the impact of montmorillonite-based products to reduce phosphorus magnesium and calcium in raw rapeseed oil was evaluated. With the press capacity of about 10 kg of oil per hour, the oil yield was about 30%. The technology has allowed the reduction of phosphorus, magnesium and calcium to trace amounts <0.5 ppm. Based on the results, the compatibility of oil quality with the applicable quality standard of vegetable oil used as fuel for diesel engines DIN V 51 605 was proven.
