Abstract
A gizzard harvester is disclosed having a pair of opposed conveyors for receiving a gizzard and holding the same against rotation as the gizzard is advanced onto a rotating cone spindle which both washes foreign matter from the gizzard and removes its lining by rotating the lining with respect to the gizzard. Washing ports are provided at the tip of the cone, which ports also assist removal of the liner from the spindle.
Claims20
A device for removing foreign material and lining from a gizzard, comprising
- means for holding the gizzard against rotation,
- a tapered spindle head having a tip facing the holding means,
- means for producing relative linear movement between the spindle head and the gizzard so that said tip enters the gizzard,
- means for producing relative rotation between the spindle head and the gizzard,
- said spindle head being adapted to engage and rotate the gizzard lining as said relative rotation occurs, thereby to separate the lining from the gizzard,
- said gizzard advancing means comprising a lower endless conveyor and an upper endless conveyor,
- the paths of both said conveyors having portions parallel to and facing one another, and
- said holding means comprising two series of flights attached to respective ones of said conveyors,
- said flights being configured to form, between the conveyors over the portions facing one another, a series of pockets for holding a series of gizzards and preventing rotation thereof while advancing the gizzards onto said spindle head.

- loading a series of gizzards onto a conveyor,
- moving said gizzards along said conveyor onto a rotating spindle having a tapered head with irrigating means to remove the debris,
- forcing said gizzards over said head to remove the liners therefrom, and
- ejecting said liners from said head.
