Resonance conveyors for sardine processing

Click2Contact

In March 2015, Vibration Systems & Solutions (VSS) was approached to design conveyors to transport 7 t/h of sardines for a pet food processing project.

Netter FlexiLink technology was used, in which the conveyor trough is mounted on blade springs, with special connections between the tray and base of the conveyor. The drive unit was by a Netter NTK pneumatic vibrator and uses the resonant frequency of the springs to move the tray. Much like pushing a car, where, once moving, little energy is required to keep it moving, so too with the FlexiLink system which needs little air to operate. This gives a smooth vibratory action, with no harsh jarring of the tray (and product) as with crank arm-type drives.

VSS supplied the links, blades and vibrator for two conveyors and the client made the trays in his own workshop.

Shortly after this order was completed, another processor requested a similar system, but this time to handle 15 t/h. VSS upscaled all the parts and created conveyors that can theoretically move 17 t/h of sardines, quietly and with minimal air use.
