Putting an eel on a spear to smoke can be a time-consuming and dangerous job. ST915 passes a rod through the eye area of the farmed eels (100-250g) and places them at a good distance for smoking. The preformed tray allows the operator to easily manually feed the machine into the pneumatic spear +/-20 eels per minute. By pressing both buttons at the same time, the operator's hand cannot get close to the system, as this would turn off the guard and push the spear. When the pusher system retracts, the machine loads new spears for the next batch.
