Spiral conveyor for continuous cooling/cooking of food stuffs has belt tensioner to maintain belt tension at level so that belt is driven only by drive force of drum turning drive
The conveyor system (1) has a first continuous conveyor belt (2), a vertical conveyor drum (3) with turning drive. A belt tensioner (6) maintains the set/setable belt tension at such a level, that the belt is driven only by a drive force transmitted via the turning drive to the belt. The belt tensioner and a belt length compensator form a modular unit. Tensioning force is generated by gravity using a tensioning weight (60), or by spring force.
