• Where can I test rapeseed from industrial oil mills?
  • The EthaNa ? pilot plant at Fraunhofer CBP is now available for test runs with the rapeseed from industrial oil mills, to provide product samples on a larger scale. New systems can also be integrated into the existing infrastructure at oil mills as alternative processing lines.
  • 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 is rapeseed processed?
  • Schematic representation of the processing of rapeseed: conventional processing in industrial oil mills (left) compared to the EthaNa process based on ethanolic native extraction (right). In the de-hulling plant, up to 100 kilograms of rapeseed per hour can be de-hulled in continuous operation.
  • How to maximize rapeseed oil yield?
  • In the present study, the optimization aimed to maximize rapeseed oil yield by selecting the suitable screw pressing conditions, i.e., the best nozzle diameter, press head temperature, and screw frequency in the applied experimental domain, by employing the desirability function method.
  • Can rapeseed be used in the production of oil and protein?
  • In this review, the use of rapeseed in these applications is presented, starting with the preparation of oil and protein from the seeds, before their release in the market, to the utilization of natural unprocessed rapeseed.
  • 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 ¡ãC 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.
