    The invention relates to the sorting of seed by width, thickness, length and weight of grain. The purpose of the invention is to improve the quality of the finished products. For this, the working channel (RK) 1 of the device is annular and consists of two opposite curvilinear segments 2, 2b and the upper 3 and the lower 3b straight linear segments associated with them. The inlet slot 6 (VP) 6 is located in the inner wall 5 of RC 1 in the interface of segment 3b with segment 2, and the discharge device 10 for the light fraction in the outer wall of 7 RC1 in the interface of segment 3b with segment 2. On the outer wall 7 of the RK 1, opposite the VP 6, there is an outlet opening 8 for seed material, and in the interface area of segment 3 with segment 2 - a fan 4. Section 2, located after VP 6, is made of two sections 9, 9b with different radii curvature. Moreover, the radius of curvature of section 9 adjacent directly to VP 6 is larger than the radius of curvature of section 9b adjacent to segment 3. The air flow describes a curve around VP 6 a trajectory. As a result, each individual particle encounters airflow across its flight path and forms the largest possible fan of material. Lightweight material is divided into three partial streams. Lightweight material is diverted through device 10, medium to sieve unit 11, and heavy is used as seed. 1 il.

    adjacent to segment 3. The air flow describes a trajectory around EP 6. Due to this, each separate particle is encountered with an air flow across its trajectory.
    This is a fan of material. Lightweight material is divided into three partial streams. Lightweight material is discharged through tool 10, medium to sieve device 11, and heavy
    flight and is formed as much as possible as a seed. 1 silt
    The invention relates to a method for preparing a seed material in which the seed material is freed from light impurities such as straw, husk, weeds, and sorts the seed material by width, thickness, length and weight of grain. The invention also relates to a device for pre-sorting seed.
    The purpose of the invention is to improve the quality of the finished products.
    The drawing shows the device9 overall view.
    A device for preliminary sorting of seed material consists of an annular working channel 19 made up of two opposite curvilinear segments 2S2 and the upper 3 and lower 3 straight line segments matching them. In the annular working channel 1 there is a turbo-blower or axial fan 4, B . the inner wall 5 of channel 1 in the junction zone of the lower segment 3 s. a curved segment 2 is located inlet slot 6. In the outer wall
    7 annular channel 1 opposite the inlet slot 6 provides an outlet 8 for seed material.
    In the illustrated embodiment, the curved section 2 of the annular channel 1, located immediately after the inlet slot 6, consists of two sections 9.9 with different radii of curvature. In this case, the radius of curvature of section 9 adjacent directly to the inlet slot 6 is larger than the radius of curvature of section 91 s adjacent to the upper segment 3 of the channel, 1. At the end of section 2, a discharge device 10 for a light fraction, such as dust and husk, is located.
    The device works as follows.
    Airflow describes around the slot. 6 curve trajectory. Due to this, each individual particle encounters an air flow across its flight path and forms the largest possible fan of the material. Separate particles after exiting the air flow through the outlet 8 to the flight trajectory, subject exclusively to the force of gravity, and the boundaries of separation are further stretched until the particles go to free fall. In the illustrated embodiment, the ill material is divided into three partial streams LG, MG and SG. Lightweight material LG is diverted through tool 10, Medium material MG is brought to conventional sorting devices, for example, to a sieve 11, Heavy SG material bypassing conventional sorting devices is directly used as seed material. Under the known conditions, as shown in the drawing, they are. the material may still be screened with a sieve 12, and at position 13 a coarse sifting transition is obtained, at position 14 - a partial material and at position 15 - a screening of a sorting screen,
    Spirits are guided in a circular motion around the seed inlet, and light particles that are entrained during the sorting process enter the outer zone of the annular channel 1, where they are separated from approximately 10% air, 90% of the total the amount of air circulates through the turbocharger or axial fan, with approximately 10% of the air being continuously updated. Separate air through the Tyler and Cyclone, respectively filter, is directed to the atmosphere. The missing amount of air is sucked through the release of seed, namely in the zone of heavy material.
