<p>Agitation for gas/liquid reactor for fermentation processes. Dished annular stationary guide plate has radial guide blades round the upper edge and immediately above it is rotated a blade-wheel. Specifically the guide blades may be curved, and their height may be reduced outwards. The assembly may be set in the bottom of a tank through which flows material under treatment, gas being admitted at the bottom under the guide plate.</p> |
