  • Pos 11: External preheaters allow to optimize treatment conditions and to make use of synergistic effects of heat. They can be used in a scale of 20 to 200 l/h. Pos 12: With an external cooler the product can be cooled after the treatment, in a scale of 20 to 200 l/h.
  • Transcript

    • 1. Pulsed electric field application as a cell disintegration and decontamination technique for food-, bio- and environmental engineering Stefan Toepfl
    • 2.
      • Increased competitiveness through efficiency improvements of the production processes used, e.g. by improved energy management, automation or application of novel technologies on material conversion.
      • Support of the industry with new production processes Focus of development:
        • Pulsed electrical fields
        • Extrusion
        • High pressure
        • Ultrasonic/shock waves technology
        • Application of supercritical fluids

    • 3. Pulsed Electric Fields Processing
    • 4. Pulsed Electric Field Processing Effects on biological tissue
    • 5. Impact of PEF-treatment (2 kV/cm) on Jona Gold (JG) and Golden Delicious (GD) juice yield using a decanter centrifuge. Juice yield including an eventual transition of solids to juice Pulsed Electric Field Processing Effects on apple tissue
    • 6. Olive oil recovery, Spain Replacement of malaxation process with same yield Pulsed Electric Field Processing Effects on olive tissue
    • 7. Cotton seed oil recovery, India ELCRACK-treatment: 2 kV/cm, 20 kJ/kg PEF Processing Effects on cotton seed
    • 8. The rockweed (Ascophyllum nodosum) is harvested mechanically on the littoral shore. Kelp (Laminaria digitata) is harvested by a coaster equipped with a dredge. The weed is brought to the plant in the coaster at the end of each day and landed. Products: Meal with variable particle size PEF Processing Seaweed processing
    • 9. PEF Processing Seaweed processing
