CONOVEY Spiral Conveyors
CONOVEY has a long history of building high quality spiral conveyors, coolers and spiral freezing systems.
Spiral conveying systems can be used effectively to elevate, lowerate, accumulate, proof, heat/hold, cool and freeze a near endless variety of food and CPG products. The single most important advantage of spiral conveying is its unique ability to provide hundreds or thousands of linear feet of conveying surface in a compact footprint. CONOVEY offers three different spiral conveying technologies, each with its own advantages.
CONOVEY Positive Drive Spirals
We recommend our Positive Drive Spirals for both new systems and when upgrading your older Conventional Slip Drive Spiral systems.
Positive Drive Spirals are an the preferred alternative to Lotension Slip drive systems. Positive Drive chain features a stainless-steel grid belt with driving tabs on the inside edge. The tabs engage and are driven by UHMW vertical ribs on the spiral center drum. PosiDrive Spiral™ is recommended particularly for applications where product movement is a problem, or where oils or other product characteristics cause operational issues with Lotension drive systems.
OutRunner Spiral Conveyors
CONOVEY manufactures these innovative OutRunner Spiral Conveyors under the Span Tech brand of quality conveyor systems.
The OutRunner Spiral Elevator conveyor is driven by a single gearmotor, but each 360-degree revolution is individually driven via vertical line shaft with sprockets at each tier driving the external edge of the chain. Rather than trying to drive all of the chain from one end, the spiral conveyor design allows each tier to share the load, offering many advantages including great flexibility in loads, speeds and incline angles.
Conventional Slip Drive Spirals
CONOVEY will build traditional slip drive spirals upon request. There is still a large market for these conventional spiral systems.
The main drive component of a slip drive spiral conveyor is the cage and it provides the main source of drive for the conveyor belt. The belt edge is held in tight contact with the cage so that the friction that is created by the wraps of the belt around the cage is sufficient to drive the belt through the system. An auxiliary drive is required to providing just enough pull force to keep the belt in tight contact with the drum and help set belt speed.
