In the can manufacturing process, most washers operate through a series of carefully structured stages, each designed to ensure optimal cleaning and preparation of cans. Here’s a breakdown of the stages involved:

The process begins with a pre-rinse stage, where cans are initially rinsed to remove loose debris.

Next, a heated and high-pressure pre-wash is conducted. This stage prepares the cans for deeper cleaning by loosening any stubborn residues.

Following the pre-wash, a second heated and high-pressure wash occurs, effectively removing contaminants from the can surfaces.

After the washing stages, the first rinse removes any residual cleaning solutions from the cans.

This stage involves a heated treatment to further ensure that all contaminants are eliminated and to prepare the cans for the final rinses.

The second rinse follows, ensuring that any remaining residues from the heated treatment are washed away.

In this critical stage, deionized (DI) water is used for rinsing. Unlike previous stages, the rinsing solution here is not pumped from a tank; instead, it is supplied directly from the deionizing system. Any overspray is then pumped back to the deionizing system for reuse.

Finally, the mobility enhancer stage is introduced to facilitate better handling and processing of the cans as they move through the manufacturing line.

Each stage of the washer is equipped with a recirculating tank, which holds the solutions applied to the cans. The system pumps these solutions through spray bars or risers, with nozzles positioned strategically above and below the conveyor mat to ensure thorough coverage. After application, the solution drains back into the tank, maintaining an efficient and effective cleaning process.

Each tank is equipped with a pump and a motor, ensuring that the cleaning solutions are circulated effectively throughout the washing stages. This configuration is essential for maintaining the performance and longevity of the washing system, ultimately leading to higher quality can production.

This structured approach to washing not only enhances cleaning efficiency but also plays a critical role in maintaining the integrity of the cans throughout the manufacturing process.
