AERATOR AND FERMENTER WITH AERATING AND FERMENTING APPARATUS Russian patent published in 1997 - IPC

FIELD: microbiology, food-processing, medical industry for anaerobic cultivation of microorganisms in cleaning units and units for providing basins with oxygen. SUBSTANCE: aerator has pump submerged into liquid water and provided with outlet ejector, whose inlet side is communicated with atmosphere. Pump is positioned in cup disposed perpendicular to surface of liquid medium. Outlet of ejector is inclined to vertical plane. Cup may be provided with guiding gas distributing devices. Fermenter has aerating and mixing device with pump submerged into liquid phase of fermenter. Pump inlet is communicated with air medium. Ejector inlet may be communicated with gaseous medium of fermenter, outlet may be inclined to vertical plane and pump may be placed in cup. Ejector may be equipped with air medium intake device with perforated flare and pump may be positioned in outer liquid circulation circuit. EFFECT: reduced power consumption, decreased production costs, increased efficiency of water medium aeration by continuous flow of circulating liquid phase. 8 cl, 1 dwg
