I was recently contacted by a manufacturer of specialty food products that was looking to increase productivity on one of their packaging lines. In order to do so, they needed a longer Super Air Knife.
They manufacture a variety of different products, but this application was involving small snack-size blocks of cheese. They’re placed into individual plastic containers and before they seal the packaging any residual particles must be blown off or it will affect the seal. Any residual particles of cheese around the container would allow air to come into contact with the product and affect shelf-life.
In the current setup, they were using EXAIR’s Model 110012SS-316 a 12” 316 grade Stainless Steel Super Air Knife and the Model 9060 Universal Mounting System. They wanted to add in an additional two rows of cheese to help increase throughput. To do so, he needed an overall width of 18”. We do have an 18” available from stock, but rather than having a spare 12” model lying around he wanted to try and utilize what he had without having to purchase an entirely new knife.
Fortunately, EXAIR’s Super Air Knives can be coupled together to create a wide variety of different lengths. From stock, the Super Air Knife is available from 3”-108”. With the help of a Super Air Knife Coupling kit, we can achieve much longer lengths. In this case, although we did have an 18” knife available, we could also couple the existing 110012SS-316 (12”) with our Model 110006SS-316 (6”). This option was a bit cheaper than going with a new knife, and still allowed them to utilize the 12” that they already had.
While this isn’t the typical place we’d recommend a coupling kit, it was an option that allowed the customer to save a bit of money but still get the same effect that they’d achieve with the 18” single piece knife. We also manufacture a wide variety of custom knives per customer specifications. If you’ve got an odd application that you don’t think is best served by a stock offering, give us a call. An Application Engineer will be happy to take a look at your application and help recommend the most suitable product.
