The present disclosure relates to the technical field of solid-liquid separation of grain fermentation, and provides a solid-liquid separation mechanism and solid-liquid separation method for grain fermentation. A filter screen cylinder mechanism is inserted and mounted at an upper end of a rotating seat. According to the present disclosure, the rotation of the filter screen cylinder mechanism and a rotating disc mechanism has a speed difference, to realize the rolling and solid-liquid separation of fermented grain on an inner wall of the filter screen cylinder mechanism by rolling cylinders; and the rolling and solid-liquid separation is performed on fermented grain on an inner wall of the filter screen plate by the rolling cylinders, and the liquid in the fermented grain on the inner wall of the filter screen plate is rolled out, achieving a more thorough solid-liquid separation.

A centrifugal solids-liquid separator system has a drum that spins about a rotational axis with a helical channel for moving solid particles up into a blower channel and out a blower outlet, wherein the drum is moved with a variable speed to cause the solid particles to move up the helical channel. The helical channel is configured along an inside wall of the drum and the solid particles from a slurry move up along the helical channel to a top flange and over this top flange into the blower channel. The blower then forces the solid particles out of the system. The liquid of the slurry flows from a receiving base configured at the base of the helical channel or drum, out of a liquid outlet to exit the system for collection or disposal. A motor spins the drum and may power the blower to operate the system.
