Unit for separation of seeds (Fig.1, Fig.2) contains four roller supports 1, which has a circular shells 2 and 3, which set forth the net body 4 qi�andrijeski shape coaxially with and rigidly mounted therein by known means perforated hollow rotor 5. The rotor 5 is formed as a hollow perforated surfaces convex shape with the centers of curvature of the inside of the rotor and also the sewing on the inside of the rotor in the form of a perforated screw blades and fitted with a receiver device 6 made in the form of a hollow perforated conical multiple-screw-shirts. Receiving a screw device 6 is rigidly fastened to the rotor 5 by known methods. The cell sizes of the perforations of the rotor 5 and the receiving devices 6 greater than the maximum size of the seeds, and the size of the mesh cells of the body 4 is less than the minimum size of the seeds. Housing 4, and with it the hollow rotor 5 with the receiving device 6 are rotated by the actuator 7. The unit is equipped with a host of water supply, including a collector 8 and two pipes 9 and funnel 10 to the substrate, a discharge tray 11 for receiving ruined fruit, a discharge tray 12 for receiving seeds and a tray 13 for the collection of fibers and water.

Thereafter, the perforated strip 16 deformity removed from the mandrel 36 is either fixed on the mandrel. Processed in the same way the rest of the perforated strips 11, 12, 13, 14. Next five deformed thus perforated strips 17, 18, 19, 20 after aligning the longitudinal edges of the perforated strips with the formation of perforated inlets 31, 32, 33, 34, 35 connected, for example by welding. As a result, the perimeter of the rotor 5 (Fig.3) on the outer surface are formed five smooth spiral lines 21-22, 23-24, 25-26, 27-28, 29-30 and five smooth inner screw grooves.

Unit for separation of seeds is as follows.

Crushed cucurbits, for example pumpkin, go through the hopper 10 in a rotary screw receiving device 6 and then into the rotor 5. Moving the crushed raw material is due to the presence of helical lines and helical blades. This provides not only transportation melons along the horizontal axis and discharge in the discharge tray 11 crushed pumpkin without seeds, but the melon split pieces into smaller fractions due to the growth of energy intensity, the power and frequency of hypervelocity flows of crushed melon with one another and with the screw surfaces of the walls of the hollow fixture 6 and the rotor 5, resulting in intense separation of seeds. Separating the seeds are removed through the openings of the rotor 5 and the fixture 6 and fall into the inner cavity of the housing 4.The removal of adhering to the rotor 5 and the housing 4 seed and fiber is water supplied to the manifold 8 and the nozzles 9. The seeds separated from the pulp of melons in the housing 4, are transported helical guide 14 to the discharge tray 12 of the reception of the seed. The use of the invention allows to increase the efficiency of the separation of seeds, expanding technological capabilities, simplifies manufacturing.

Unit for separation of seeds, containing provided with a screw guide cylindrical body mounted rotatably and mounted therein a hollow perforated rotor, fitted with a receiver screw fixture, made in the form of a hollow perforated conical multiple-screw-shirts, a host of water supply, loading and unloading device, characterized in that the rotor is made around the perimeter of five or more perforated strips of the convex curved shape, folded in a vertical plane in the longitudinal direction and curved in a spiral lines in the transverse direction of the barrel on the mandrel with the formation around the perimeter of the rotor screw lines and screw perforated surfaces convex shape with the centers of curvature of the inside of the rotor and also the sewing on the inside of the rotor in the form of a perforated screw blade along the entire length of the rotor from loading to unloading.
