The Hard Bunch Separator & Crusher assists to segregate HB and USB. It will crush and loosen the USB just like any ordinary bunch crusher. For those poorly sterilized HB, the helical strip design on the rollers will help to push the HB forward, entering the splitting section at discharge end. The HB will be split in this section. After split, the HB will be recycled back into cages for re-cooking process therefore proper stripping can be achieved thereafter.
