Filleting fish is a skilled, somewhat messy and time-consuming job. Hundreds of tiny pin bones have to be removed before the fish goes on sale in food outlets.
To automate the process, a Swedish company has developed a machine driven by a motor that runs on compressed air.
A stainless steel air motor supplied by Parker Pneumatic is at the heart of the patented Ergo-Light pin bone remover.
The motor was chosen because of the fine degree of speed control and pulling power it provides to the mechanical plucker, which gently removes the pin bones.
The Ergo-Light, designed to work continuously for more than eight hours in the worst conditions, removes pin bones from most fresh, defrosted or smoked fish fillets, delivering the best results after rigor mortis has set in.
The unit can be immersed in water and is easily cleaned.
Parker produces air motors to customer specification. The standard range delivers powers from 90W to 1200W, providing speeds between 50rpm 2200rpm.
