Abstract: A roller for a conveyor system comprises a nonlinear bore hole to facilitate retention of the roller on a roller-receiving portion of a corresponding shaft. A nonlinear bore hole comprises a central cylindrical portion for receiving a roller-receiving portion of the shaft and unaligned slots in communication with the central cylindrical portion to prevent migration of the roller from the roller-receiving portion.

Abstract: A cleanable conveyor frame and a method for making a cleanable frame having a simplified frame design. Infeed and outfeed assemblies are movable between operating and cleaning positions. An outfeed assembly includes a drive for a conveyor belt and a position limiter-scraper assembly. The position limiter-scraper assembly comprises a roller extending between two connecting plates mounted to outfeed mounting plates, a scraper assembly having a scraper blade mounted to a mounting bar extending between the two connecting plates and a leaf spring extending rearward from the mounting bar for biasing the scraper blade into contact with the conveyor belt.

Abstract: A cleanable frame and a method for making a cleanable frame having a simplified frame design. A hygienic conveyor frame assembly comprises a plurality of hollow tubular sections joined together to form an evacuated, sealed conveyor frame support structure that functions as a sterilization zone. An integral carryway is placed on the support structure. Lifters coupled to the conveyor frame can lift the carryway and conveyor belt for cleaning. Infeed and outfeed assemblies are also movable between operating and cleaning positions. A sensor can monitor the conditions of the frame interior to ensure that the vacuum is maintained and initiate a corrective action if the vacuum seal is breached.
