ABSTRACT:
Herein described is a machine for removing raisins spoiled by mold from good raisins. An angularly disposed rotating screened cylinder causes raisins to be lifted and dropped to the bottom of the cylinder. Because of the fact that the bad raisins are soft and sticky they will stick to the screen. Good raisins will be tumbled towards the bottom of the screened cylinder and out. Spray nozzles force water through the screened cylinder washing the stuck raisins into a trough where they are kept separate from the good raisins.
