1. A conveying system for transporting a product in vertical direction, comprising:
a drivable endless first conveyor belt and a drivable endless second conveyor belt, each having a conveying section configured to support and transport a product and a return section, which conveying section extends along at least a helical path including a plurality of windings about a centerline between a lower end and an upper end of the helical path, wherein the lower end of the helical path of the conveying section of the first conveyor belt is located at a lower level than the lower end of the helical path of the conveying section of the second conveyor belt, wherein the upper end of the helical path of the conveying section of the second conveyor belt is located at a higher level than the upper end of the helical path of the conveying section of the first conveyor belt, and wherein the upper end of the helical path of the conveying section of the first conveyor belt is located between the lower end and the upper end of the helical path of the conveying section of the second conveyor belt; and
a transfer region between the lower end of the helical path of the conveying section of the second conveyor belt and the upper end of the helical path of the conveying section of the first conveyor belt where the first and second conveyor belts extend parallel and next to each other and move in the same direction of movement under operating conditions and with a transfer member configured to displace a product between the first and second conveyor belts at the transfer region.
