Pisces - Model 400 - Pin Bone Removal Machine

The Uni-Food Technic Pin-bone Remover machines remove up to 95% of pin-bones.

After pin-bone  removal the fillets pass a table for manual inspection.

The machines can work in a one-way flow with automatic in-feed  after the trimming line.  Regardless if the fillet has been pre-handled in a filleting machine or if it has been cut by hand, the pin-bone machines remove 90-95% of all the pin-bones.

We have obtained optimum utilization by using the machine for salmon and mackerel 18-24 hours after slaughtering depending on the structure of the fillet. Hereby we minimize gaping issues and problems with broken pin-bones.

On fresh fillets, water is used for cleaning of the roller and knife. Air is used for cleaning of the rollers when smoked fillets are processed.

As a standard the machines are supplied with water cleaning, but can be provided with both water and air connection, in order for it to be used for both kinds of products. The machines are built in a strong stainless steel construction. All parts used are made in FDA approved materials.

• Adjustment of the pressure on the fillet is made by spring pressure.
• Tooth roller with built-in water/air nozzles for automatic cleaning of the roller and knife.
• Adjustable knife holder.
• Fine adjustment of belt angle to obtain a bend on the fish to visualize the pin-bones before removal. Adjustment depends on the thickness of the fillets.
• Quick-release for removal of conveyor belt for cleaning. When the belt is removed the machine is open for cleaning. The belt can then be put into a disinfecting bath.
• Waterproof cabinet for motor and electrical parts. The electrical parts are protected in an extra box inside the cabinet.
• The knife and roller have a width of 230 and 350 mm, respectively. The width of the knife makes in-feed precision less important. The machine can therefore easily be placed after an automatic in-feeding machine.
• Can be provided with an underlying dripping tray.

• Extremely efficient
• Gentle to the fillets
• Minimizes production costs
• Fewer operators are needed
• Return of investment

• Capacity: Our models range from 10 to 50 fillets/min (depending on size and species)
• Process temperature: +4°C to +6°C (the machines are not suitable for frozen fillets)
