1. wheat-germ oil cold pressing method for distilling may further comprise the steps:

  • Fresh wheat germ is removed flour, wheat bran in the wheat germ through separator, and purity reaches 99%;

    With the softening sterilization treatment of wheat germ;

    The wheat germ oil press of packing into is extracted oil automatically;

    Washing, with the oil refining still of packing into of the crude oil after filtering, indirect to 75 ℃

    begins to stir, rotating speed 20-40 rev/min, add 85 ℃

    of hot water of 5% through shower nozzle, stop after 5 minutes stirring, leave standstill 2 hours after, emit water and sediment;

    Vacuum drying, when oily temperature reaches 75 ℃

    , vacuum drying, so that moisture reduces to 0.05%,Smart filter is cooled to 30 ℃

    with the circulation of embryo oil cold water, filters through 400 orders, removes suspension and impurity,Wherein, said softening sterilization treatment comprises;

    wheat germ was steamed in softening kettle 25-35 minute, and mixing speed is controlled at 20 rev/mins;

    Temperature is controlled at 75~

    80 ℃

    , and the wheat germ molecule is expanded, and increases plasticity;

    After stopping steam;

    Continue roasting and fry, when wheat germ moisture reduces to 10%, can the wheat germ oil press of packing into be extracted oil automatically.
