The new Trio FDS 35 (standard) & 35i (Industrial hi-stability knife) are the latest industrial scale freeze drum skinning machines from Trio Food Processing with improvements in design that will increase yield by 2-5% compared to older Trio skinning machines. The new design is more hygienic and makes it easier and safer to operate and service. The FDS 35 is designed on a substantial steel frame made from 18/8 stainless steel. All parts that come into contact with the fish are made from stainless steel and plastic.
