303 Stainless Super Air Knife in Mango de-watering process

Recently, I was working with a customer who specializes in post-harvest fruit processing. In this case, they were processing mangos from complete fruit down into cubes which are subsequently cleaned and packaged into plastic bags and then cardboard boxes for use in other food products.

When the customer contacted me, they were using a stainless steel pipe with holes drilled into it to de-water the fruit chunks after being sprayed to clean the individual pieces. They were using stainless steel pipe as they had a requirement for stainless steel construction due to being food grade facility. The problem with the pipe was that the airflow didn’t provide an even blowing force across the full, 30 inch width of the vibratory conveyor. The pipe solution also used quite a lot of compressed air. Unfortunately the customer could not measure what it was, but they gave me the number and size of the holes drilled into it. From that information, we could determine that they were using about 150 SCFM of compressed air at this one location.

And so, with the ineffectiveness of the pipe as well as the high air consumption, the customer went looking for something better. That’s when they found EXAIR Stainless Steel Super Air Knives on our web site. After some quick discussion to sort out the width of the conveyor and to establish what the need was, we settled on model 110030SS (30” 303 Stainless Steel Super Air Knife) to be mounted across the width of the conveyor (see photo above).

With the Super Air Knife installed, the customer was able to achieve the effectiveness he needed for the de-watering and at an airflow rate that was 42% less compressed air use than what he had before. Some of the other benefits that they were able to achieve without even being conscious of it were the enhanced safety of the OSHA compliant Super Air Knife and the sound level was cut dramatically as well.

EXAIR’s Super Air Knives are used many times in processing and packaging applications to provide a non-contact method for de-watering, blowing off dust, moving product off to one side, drying, ejecting and many more applications like these.
