FIELD: machine building. ^ SUBSTANCE: invention refers to flour-milling industry and can be used during development of non-bolting, high-capacity, compact, economic flour-milling complexes, including on the basis of rolling machines. Vacuum sieving machine includes housing with two sieving chambers divided with a central partition, two inlet branch pipes for supply of air mixture, two sieve frames with a sieve, two outlet branch pipes for passing fractions and one outlet of tailing fractions of each of the chambers, two rotors with guides, which are located on common shaft. Outer hub (relative to central partition) of each of the rotors is offset to the rotation side relative to inner hub through an angle of 1-30 for offset of guides and providing the direction of movement of ground materials with guides of each of the chambers towards central partition to common tailings outlet located in the middle of the machine housing. ^ EFFECT: increasing sieving capacity, as well as simplifying the design and improving the reliability of the machine. ^ 4 dwg |
