FERMENTER FOR CULTIVATION OF BIOMASS OF METHANE-OXIDISING MICROORGANISMS METHYLOCOCCUS CAPSULATUS Russian patent published in 2020 - IPC C12M1/04 C12M1/00 

FIELD: biotechnology.

SUBSTANCE: invention relates to biotechnology, in particular to fermenters for cultivation of biomass of methane-oxidising microorganisms Methylococcus capsulatus used in fodder production, which is used in livestock sector, poultry keeping and fishery. Fermenter for cultivation of biomass of methane-oxidising microorganisms Methylococcus capsulatus contains two and more coaxially heighted reaction chambers (1, 2) in cylindrical housing of fermenter (7). Inside each chamber contains circulation tubes (8, 9), at the bottom of which there are bubblers for oxygen-containing gas (5) and natural gas (4). In each chamber under circulation pipes (8, 9) transverse partition (6) with nozzles (3) is made. At that, nozzles are arranged so that axes of nozzles coincide with corresponding circulation tubes and are directed with narrowing upwards. Diameter of narrowing of each nozzle is smaller than inner diameter of corresponding circulation pipe. Above the top edge of each circulation pipe there are profiled deflectors (10) directed with smaller diameter downwards. In each reaction chamber height of end clearance between circulation pipe and located under it transverse partition (6) with nozzles (3) and above it deflectors (10) is 0.35-0.8 of outer diameter of circulation pipes. In lower chamber of fermenter there are branch pipes of liquid process flows (11, 12, 13, 14), and in upper chamber there is branch pipe for outlet of formed gas-liquid mixture (15).

EFFECT: invention provides a technical result consisting in improvement of efficiency of the process of producing protein mass in the reaction volume of the apparatus of a homogeneous, fine gas-liquid medium due to exclusion of stagnant zones and increase of speed of mass exchange processes in gas-fluid-cell system with simultaneous reduction of specific energy consumption.
