A group of us went to the northern part of Ohio to do some fishing. We had a great time. We caught a variety of fish; even some small ones like above. We had one person that could fillet fish; and, we definitely let him do the work. I enjoy eating fish, but I do not enjoy the fish bones. If the fish is filleted correctly, finding a bone is rare. Now, traveling from a small boat in Ohio to an international commercial fishing company, it is also important to keep the bones at a minimum. A salmon processing plant contacted EXAIR about our Line Vacs for removing fish bones.
In 2014, this processing plant purchased two 1 ½” 316SS Line Vacs, model 6063-316, to remove bones from salmon fillets. The Line Vacs were positioned after the “bone removal” rollers. Cups that spanned across the salmon fillets were attached to the vacuum end of the Line Vacs. They loved how the product worked without any moving parts, and how compact and reliable they were since they were in operation for over 6 years. But they needed to increase fish production rates; so, they needed a higher conveyance rate to remove the bones. They sent me a photo of their current process (reference below).

The interesting thing was that they welded sanitary flanges to the ends of each Line Vac. Sanitary flanges are great for mandatory and frequent cleaning. And believe it or not, EXAIR introduced Sanitary Flange Line Vacs™ in yr2017. At EXAIR, we are always progressing with new products to solve different issues in a variety of industries. The Sanitary Flange Line Vacs were designed for food and pharmaceutical industries. For this customer above, they were surprised and amazed that we added the Sanitary Flange Line Vacs to our product line.
So, now they would not have to weld flanges. This would save them time from welding and buffering to remove any “catches” inside where bacteria could grow. They wished to replace their current Line Vacs with 2” size Line Vacs to increase the throat diameter and conveyance rate. Since they requested the 2” size, I recommend the model 161200-316.

The Sanitary Flange Line Vacs can fit within sanitary piping systems to convert pipes into a useful conveyor for bulk material and waste removal. They use an ISO2852 flange for easy disassembly and cleaning to reduce bacterial entrapment. They ae made from 316 stainless steel material for superior corrosion resistance. EXAIR manufactures four different sizes from 1 ½” up to 3” flanges. If we were three years earlier in production at EXAIR, it would have been an easy choice for this fish processing plant.
EXAIR Line Vacs use a small amount of compressed air to generate a powerful vacuum by a Venturi effect. The unique design of the generators creates a high velocity of air to create a low pressure on one side and a powerful thrust on the other. You can watch a video of the operation of a Line Vac HERE. Compared to other vacuum or conveying systems, the EXAIR Line Vacs are very quiet, rugged, and powerful. For sensitive applications where cleanliness is a major need, the Sanitary Flange Line Vac are designed for these conditions.
If you need to convey solid materials in a quick and easy way, an EXAIR Line Vac could be a solution for you. We have them in a variety of formats, materials, and sizes to easily match your application. For the salmon processing plant, it improved their operations in removing fish bones. EXAIR Line Vacs can save back-wrenching labor of picking up bags, climbing stairs, and dumping material into hoppers. If you want to know if the EXAIR Line Vac could work for you, please fill out the Line Vac Data Sheet (click HERE). An Application Engineer at EXAIR will help to recommend the best unit for you. But, if you want to catch fish, you may want to ask a professional 😊.
