What is the mass flow rate of pressed rapeseed oil?

The temperature of the pressed oil at the exit from the press was 40 °C. The mass flow rate of the press cake and pressed rapeseed oil under these pressing conditions were 174?±?22 g/min and 52.7?±?0.1 g/min, respectively. Optimization of screw-pressing process factors can involve the oil recovery yield or quality properties.

How is rapeseed oil obtained?

Rapeseed oil was obtained by cold pressing in a laboratory hydraulic press (Sirio, Mikodental, 10-ton strength, 40 MPa maximum pressure) at room temperature. The procedure was done in triplicate. Upon pressing, oil samples were immediately analyzed.

How screw press conditions affect rapeseed oil yield?

The operating screw pressing conditions can significantly affect the oil yield from rapeseed. For a given screw press and seed, the main factors affecting the rapeseed oil yield are nozzle diameter, head press temperature, and screw frequency.

How much rapeseed oil can be extracted by cold pressing?

A nozzle diameter of 10 mm, a screw frequency of 50 Hz, and a press head temperature of 80 °C ensured the maximum pressed rapeseed oil yield of 26.65% within the applied experimental domain. The crude oil extraction degree achieved by cold pressing was 60.8% of the rapeseed oil yield obtained by the Soxhlet method.
