Abstract:
1. A quasi-continuous centrifuge serving to remove surface oil coatings from snack food products upon their emergence from an oil cooker, comprising a upstanding frame, a shroud mounted upon said frame, a drive shaft, centrally mounted with respect to said shroud, shaft driving means operatively coupled to said shaft, a cylindrical drum having perforate wall structure permitting oil passage therethrough mounted radially inwardly of said shroud and constructed to be rotated by said drive shaft, a plurality of vertically spaced apart, conically formed baffles fixedly mounted upon said drive shaft with the baffle apexes projecting downwardly, a plurality of vertically spaced apart, frusto-conically formed internal chutes fixedly mounted upon said drum, each having a central opening permitting passage of product therethrough, a product input feed chute mounted with respect to said frame affording entry into the drum of product to be treated, a product discharge chute mounted with respect to said frame affording discharge from said drum of product treated in the centrifuge, and said shaft driving means including motor control means serving to permit rotation of said shaft, drum, baffles and chutes in an acceleration mode, a high speed running mode, a deceleration mode and a low speed dwell and product discharge mode so that oil coated product fed into the input feed chute and received upon one of said conical baffles, is thrust outwardly against said perforate drum wall and held there until the end of the high speed running mode wherein surface oil is stripped from the product which then cascades downwardly towards the product discharge chute and exits the centrifuge with low kinetic energy.
