The „Air Blast“ Reject System
When it comes to the contactless, rapid, and material-friendly removal of contaminated or faulty products, the Air Blast (also known as the “Air Nozzle System”) is an unbeatable tool. It is particularly suitable for light, small, and sensitive goods from sectors such as food or hygiene.
How does the Air Blast Work?
The principle of the air blast is as simple as it is effective: When a contamination is detected – be it by a metal detector or an X-ray inspection system – the control valve of the unit is activated lightning fast. A precise, short, and powerful burst of air from the nozzle hits the product, contactlessly diverts it from the conveyor stream, and transports it into the designated reject container.
The entire process occurs within milliseconds. The air blast immediately returns to its resting state to be ready for the next product.
The advantages of the Air Blast
The Air Blast is characterized by its extremely fast reaction time. This allows for the reliable inspection and rejection of over a hundred individual products per minute. This makes it ideal for high-speed lines where products follow closely one after another.
Since no mechanical parts come into direct contact with the product, the air blast is easy to clean and meets even the strictest hygiene requirements – a must in the food industry.
Special Versions
For dual-lane operation, outward-facing air nozzles can be fitted in the middle of the belt. For heavier products, a double air blast nozzle may be necessary. Special nozzle shapes can also be customized to exactly match the air jet to the product profile, thereby maximizing efficiency.
Conclusion
Where speed and hygiene for light products are paramount, the Air Blast is the first choice. It ensures a highly precise, rapid, and gentle removal of contaminated and damaged products, thus guaranteeing uncompromising quality.
