But at present with the energy crisis and the environment problem gradually grave, the solid state fermentation technology arouses people with whose proper merit extremely large interest, there is existing very big degree of difficulty in solid state reactor design. How the temperature controlling the reactor inners effectively , humidity , the amounts being ventilated and the matters concerned PH etc. have become the call for designing important few of solid state fermentation reactor. Time of graduation practice is that a few specifically for solid state fermentation require that the first step makes the solid state fermentation equipment according with call for out originally mainly. This solid state fermentation reactor designing that out is by the fact that cooling liquid flows in the box body mainly, quantity of heat by the fact that thin-wall absorbs the box inner fermenting. Let the solid state thing blend equation , heat dissipation equation at the same time by the fact that ceaseless mixer mixing and inside are ventilated, the humidity also being able to pass the inside coming to control the box fermenting air is isoparametric. The drive part arrives at a shaft coupling by planet reduction gear , stir the axis and the transmission shaft among them passing spline interlinkage , make mixer working especially stable.
