Abstract: A spiral conveyor is described. The spiral conveyor provides an open design. The open design creates and defines a sanitary design. The combination of a cantilever frame construction (with no side frames) and the edge/side driven belting allows for access and cleanability of the spiral conveyor.

Abstract: A chain conveyor including: a frame; at least one chain configured to move on the frame, the at least one chain including a plurality of bearings configured to rotate freely; and a dynamic traction control system including: a flexible member provided to the frame adjacent to but not touching the plurality of bearings; a control body provided to the flexible member; a pressure device in fluid connection with the control body such that the pressure device is configured to selectively expand/contract the flexible member such that it comes into or out of contact with the bearings; and a controller in electronic communication with the pressure device to expand the flexible member to provide traction control when needed and contract the flexible member when traction control is not needed. A kit including elements of the dynamic traction control system may be provided to retrofit existing chain conveyors.

Abstract: A spiral conveyor is described. The spiral conveyor provides an extremely open design. The open design creates and defines a very sanitary design. The combination of a cantilever frame construction (with no side frames) and the edge/side driven belting allows for superior access and cleanability. This access and cleanability are of paramount importance to the food market, where sanitation requirements are stringent to maintain food safety by preventing bacteria growth.
