VORTEX BIOREACTOR

摘要

The invention relates biotechnology. The vortex bioreactor comprises a cylindrical tank with a lid, a device for agitating a medium, said device being located in the tank and consisting of a bladed wheel secured horizontally on a vertical shaft in the upper portion of the tank and a horizontal annular baffle mounted in the tank with a gap relative to the cylindrical walls of the tank and having a central axial orifice. The horizontal annular baffle is situated on a vertical rod that is capable of rotating. A mechanism for adjusting the position of the horizontal annular baffle on the rod is disposed on the vertical rod. A tube or telescopic tube is disposed inside the cylindrical tank and is joined to the axial orifice of the horizontal annular baffle. Said tube is affixed to the baffle from below and is disposed around the rod. The top surface of the horizontal annular baffle is provided with radial channels that are positioned from the axial orifice to the edge of the annular baffle with a downwards incline toward the bottom of the cylindrical tank.
