The PET bottles at Earth20 are received on pallets. After depalletizing, they are conveyed into an enclosed room for increased sanitation where rinsing, filling, capping and labeling take place. To start the operation, bottles enter an air rinser from Bevco Conveying Systems . At the entrance to the rinser, the bottles are picked up by parallel-gripper conveyors running at a higher speed than the infeed conveyor to pull a gap between the bottles.
