摘要
The present disclosure relates to the technical field of food equipment design and processing, and provides a high-efficiency water-saving separation screen for starch slurry and residue which includes a horizontal screen drum, a screen mesh, a screw propelling extrusion rod, a rotation drive unit and a flushing spray pipe; one side of the horizontal screen drum is provided with a feeding inlet, and the other side of the horizontal screen drum is provided with a slurry outlet and a residue outlet; the screen mesh is in a cone shape, and the cross-sectional diameter of the screen mesh gradually decreases from the feeding inlet to the residue outlet; the screw propelling extrusion rod is arranged in the screen mesh and includes a screw propelling extrusion rod shaft and a screw blade; the rotation drive unit drives the screen mesh and the screw propelling extrusion rod to rotate in opposite directions; and the flushing spray pipe is used for flushing slurry and residue on the screen drum. The present disclosure further provides a separation method adopting the aforementioned separation screen. The synergistic effects of mechanical disturbance and hydraulic overflow washing and screening are simultaneously exerted by the screen, compared with traditional curved surface screens and high-speed centrifugal screens, the usage amount of clean water and the generation amount of wastewater can be reduced, and the concentration of obtained starch slurry is increased; and the moisture content of potato residue extruded and separated out by the screen is low, and thus subsequent utilization is facilitated.
