Automatic fish filleting machines

A fish filleting machine removes the fillet (the boneless or near-boneless lateral muscle mass) from the headed-and-gutted round fish, leaving the backbone and ribcage behind as waste (frames). Automatic filleting machines use a combination of circular saw blades, flexible blades, and guide mechanisms to follow the spine and rib contour of the fish, separating the fillet from the bones with minimal flesh loss. The filleting yield (fillet weight as a percentage of the headed-and-gutted fish weight) is the key economic parameter — higher-yield machines leave less flesh on the bone and reduce raw material waste. Filleting yield varies by fish species, size consistency, and the adjustment precision of the machine for the fish size and species. Following filleting, pin-bone removal (the small intramuscular bones called pin bones in round fish — salmon, cod, hake) is required for boneless fillet products: pin-bone removal machines use rotating or oscillating rollers with fine pins to grip and pull the pin bones from the fillet.
