ABSTRACT:
The gas dual-dynamic solid state fermentation technique consists of placing the solid materials to be fermented in an air environment with pulsating pressure and cyclic flow to carry out fermentation, the fermentation apparatus comprises a horizontal cylindrical tank with a quick door mechanism, in the tank are axially disposed rectangular spacer barrels of square cross-section constructed by four baffles, in the space between baffles and the tank wall are provided cooler tubes in parallel with the baffles, in the middle of the spacer barrels are provided vertically many sets of cooler tubes, on the lower baffles in the tank is provided axially an fixed track, on which are movable tray racks that can roll on the track, the tray racks having thereon a plurality of layers of trays, at the rear of the tank is provided a centrifugal blowers for forcing gas cycling in the tank. The inventive technique and apparatus allows microbial pure cultivation, is easy for scaling up and high in fermentation virulence titre and produce no pollution. It is useful for fermentation production of biological pesticides, enzyme preparations, agricultural antibiotics and unicell albumen.
