The bottled water industry has been around for a long time, annual beverage consumption continues to increase. As a multibillion-dollar industry, bottling and co-packing regularly emerge the use of packaging machines to meet high production requirements. Listed below are some of the packaging equipment common to the bottled water industry.
Bottled water is a product that is ingested by the end-user. Therefore, it is important – in some cases necessary – that the filler product protects the product from contamination. Inverting air purifiers is used to remove dust and dirt from water bottles before adding water.
Each bottle cycle is indexed in the machine wash area, where they are secured with a bottle clamp and turned over at the sink. Once turned over, a burst of air is blown into the container to remove dust and dirt that may have accumulated during bottle making or bottle transport or storage. The waste goes into the sink and the cleaned containers are returned to the feed conveyor to reach the filling machine. Dishwashers can also use water or other solutions to clean bottles, and special dishwashers are available for semi-automatic or manual processes.
Overfilling machines can be produced as automatic, semi-automatic or desktop packaging machines depending on the level of production required. The main advantage of overfilling equipment is the machine's ability to fill bottles to the same level even when the internal volume of the bottles is slightly different. Since most bottled water is packaged in clear plastic containers, the overflow filler helps make each bottle look equally full and serves to add aesthetic appeal to the product on the shelf.
Overfill fillers achieve this goal through the use of a submerged nozzle which forms a seal at each bottle opening. The product enters the bottle through the hole at the top of the nozzle. Once the water reaches a certain level in the bottle, it returns to the product feed tank through the overflow opening, ensuring that each bottle reaches its target height.
