  • Publication number: 20230302458
    Abstract: In a hulling apparatus for producing hulled spelt seed including a lower course hulling device, and a method for producing hulled seed of a spelt grain, the hulling apparatus contains two disks, as rotor and stator, which are movable relative to each other, wherein at least one disk can be driven about a vertical rotation axis, and the disks enclose a flat annular working chamber between disk faces which face each other and are vertically spaced apart from each other, for receiving spelt products to be hulled, wherein at least one of the disk faces has a surface made of a plastic material, and the temperature of the apparatus can be controlled in the region of at least one of the disk faces.

  • Publication number: 20230149936
    Abstract: An apparatus for removing the husk from grain, in particular as a laboratory or small-scale grain kernel peeler, and for producing dehusked grain seeds, has a peeler including a first disk and a second disk movable relative to the first disk and drivable about a vertical axis. The disks enclose, between main faces made of a temperature-stable and elastic material, a working space fillable with grain from the side opposite the second disk through a central first disk filling opening. By rotating the second disk, the kernel and husk can be separated by a radial movement along the disks so that kernel and husk leave the peeler on its outer circumference via an outlet which opens via a chute into a collecting bin, the chute having a lateral air inlet supplied with an air stream so that the husks leave the chute laterally in front of the collecting bin.

  • Patent number: 6869355
    Abstract: An apparatus and method for determining grain loss of a harvesting machine. The harvesting machine has a crop-separating region with separating members. The separating members each have separation sensors for generating a signal corresponding to the crop quantity separated. This signal is delivered to an evaluating unit for further processing. Processing includes determining a separation curve for at least some of the separating zones and converting the separation curve to a characteristic quantity. From this measured characteristic quantity, a loss is determined based on a characteristic curve deposited in the evaluating unit. By avoiding direct loss measurement on the harvesting machine, the negative crop-related effects on determining grain loss are considerably reduced.
