ABSTRACT:
A double spiral conveyor includes two spiral chutes, each chute being positioned diametrically opposite the other in a helical relationship about a central axis of a central tubular support. The spiral chutes begin in the same upper horizontal plane and terminate in the same lower horizontal plane. The spiral conveyor further includes a rotatable discharge pan that receives the transported product as it is discharged from the two spiral chutes and directs the product to a predetermined location.
