Quinoa processing plant


  • Aspiration Channel

    The SCHULE aspiration channels AS and AS U are used for the separation of products with different specific gravities. The aspiration channel is primarily used to remove product particles with a lighter specific weight from a wide variety of cereals.

  • Dry Stoner

    The SCHULE dry stoners ST and ST D are used for the separation of stones in a continuous process. Due to its mode of operation, the dry stoner separates specifically heavier components from the lighter accepted product. Stones, broken glass and metal can be sorted out with a high degree of separation, even if they do not differ from the accepted product in size and shape.

  • Indented Cylinder

    The SCHULE indented cylinder is primarily used for cleaning. Alternatively, the indented cylinder is also used for sorting. By means of rotation, the indented cylinder sorts a wide variety of grains lengthwise and thus differentiates between hulled and unhulled oats.

  • Circular Screen

    The SCHULE circular screen is used in oat, wheat, rye, spelt, barley, maize, soya, pea, buckwheat, millet and rice mills as well as in silos for grain cleaning. The screens can be used to remove coarse and fine impurities from the grain as well as to classify products into different sizes.

  • Colour Sorting Machine

    To achieve the highest possible quality of the final product, SCHULE colour sorting machines are used. They can be equipped with different cameras depending on the application. Colour differences, different surface discolouration and concealed damage, e.g. below a husk, can be detected.

  • Scourer

    Unprocessed, quinoa is inedible because of the bitter-tasting saponins on its seed coat for protection against pests. Using the scourer developed by SCHULE the saponins can be removed in a dry process without the use of washing drums. As no fresh water is required, waste water is not produced. The process is simpler and the operating costs are reduced considerably.
