APPARATUS FOR SUSPENSION CULTIVATION OF TISSUE OR MICROORGANISM CELLS Russian patent published in 2009 - IPC C12M3/06 C12M1/02 

FIELD: microbiology instruments.

SUBSTANCE: invention relates to suspension cultivation of tissue or microorganism cells and can be used in food industry, biotechnologies and medicine. Proposed apparatus comprises cylindrical vessel with cover and device to aerate and mix suspension of mentioned biological substances. The said apparatus allows producing, on suspension surface, aerating gas swirled flow flowing along the vessel edges, potential vortex rate field being located at the vessel edges and axial countercurrent in near-axis zone. Note that the pressure difference between the vortex edges and centre varies from 10 to 2000 Pa. Axisymmetric body of revolution is arranged inside the said vessel, on its bottom and aligned with it, the body height being equal to or exceeding the level of the apparatus maximum filling. Side surface of aforesaid body of revolution smoothly mates the vessel bottom surface. Aforesaid body of revolution represents a cone or a cylinder with aerodynamic nose fairing arranged on its upper end face.

EFFECT: higher efficiency of cultivation due to more regular distribution of cless culture in fluid substrate.
