VORTEX BIOREACTOR Russian patent published in 2015 - IPC C12N1/00 C12M1/04 C12M1/06 

FIELD: machine building.

SUBSTANCE: vortex bioreactor includes cylindrical vessel1 with lid 2 provided with a device for medium mixing. Mixing device consists of bladed wheel 7, horizontally fixed on vertical shaft in upper part of vessel 1 and horizontal annular partition 9, installed in vessel 1 with a gap relative to its cylindrical walls, rod 10 vertically installed along axis. Horizontal annular partition 9 is located with possibility of rotation on vertical rod 10 and has retention mechanism of horizontal annular partition 9, installed on rod 10. Bioreactor is provided with pipe 19 or telescopic pipe 20, mated to axial hole 13 of horizontal annular partition 9, attached to the bottom of the last one and located around rod 10. On upper surface 11 of horizontal annular partition 9 there made are radial channels 12, located from axial hole 13 to the edge of annular partition 9 inclined downwards to the bottom of vessel 1. Horizontal annular partition 9 is designed floating, for example, from polypropylene. Inner diameter of pipe 19 or telescopic pipe 20 corresponds to diameter of axial hole 13 of horizontal annular partition 9. Area of axial hole 13 of horizontal annular partition 9 equals to cross sectional area at inlet 14 to radial channels 12 and total cross sectional area at outlet 15 from these radial channels 12.

EFFECT: improving efficiency of mixing and speeding up biochemical processes upon their carrying out using fluid mediums of various viscosity.
