#67. Drying bottles after washing

The company had problems with the bottle drying process after washing. After washing, the bottles are checked to make sure that they are sufficiently dry. If the bottles are not approved when checked, they are sorted out as scrap. Initially, the company used a fan for drying the bottles. This led to problems, as the fan only moved large volumes of air with low blowing force. Because of this, the bottles did not dry sufficiently and were sorted out as scrap.

Result
To reduce the number of scrapped bottles, the company was compelled to make its drying process more effective. By replacing the fan with an air knife, it was possible to improve drying quality. The air knife generated a much sharper air jet with a higher velocity, which ensured much better drying.
Solution
The size of the bottles meant that the best possible solution was to install a custom air knife to ensure drying that was as effective as possible. Standard air knives were either too small and failed to cover all of the intended area, or too powerful, which would have led to the use of more air than necessary. The engineer-designed air knife was optimized for the application, which allowed the company to reduce the number of bottles removed as scrap.
