Embodiments of the present disclosure provide a screw feeder apparatus for mixing wet and dry materials of grain byproducts, the apparatus including a screw conveyor mechanism, and a base. Two ends of the spiral conveying mechanism are provided with a feed inlet, a discharge outlet and a driving motor, and an enzymolysis liquid injection opening is integrated near the feed inlet. The dynamic inclination adjustment of the spiral conveying mechanism is realized through the base, the longitudinal support frame and the transverse rotating shaft, lifting mechanisms are arranged at two ends of the spiral conveying mechanism, and displacement increment in opposite directions is output through the two lifting mechanisms so that the spiral conveying mechanism rotates. The embodiment breaks through the limitation of the traditional fixed screw feeding equipment, dynamically tilts and changes the angle of the screw axis, so that the gravity component of the material and the pushing force of the blades form a multidirectional shearing force to strengthen the dispersion of the agglomerate, when the tilting angle is increased, the contact pressure of the screw blades is increased, the mechanical tearing effect on the viscous agglomerate is enhanced, the eddy effect is caused by the difference of the motion track of the material in the tilting and the horizontal direction, the stacking form is reconstructed, and the continuity adhesion layer is broken.
