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 centerline adjustable conveyor system and method may include a plurality of conveyor beams for conveying product within the system and an adjustor for controlling the outer width of the plurality of beams. The system and method may include a second adjustor that operates in conjunction with the adjustor for controlling the outer width of the plurality of beams. The system and method may also include an adjustor belt coupling the adjustor and the second adjustor that transfers activation of one of the adjustor and second adjustor to the other of the adjustors. The system and method may use an adjustor that is a trapezoidal lead screw. The adjustor may be a 5 mm per rev. pitched screw having opposite direction pitches emanating from the center of the screw and each opposite pitch of the adjustor may adjust one of the plurality of conveyor beams.
