OTB50 Derinding and defatting skinner

Maximized yield and minimized rework

• Ideal operator ergonomics
• Space-saving designs for processing lines
• Highly flexible setup
• Class-leading hygiene
• Low cost of ownership


The OTB50 has been designed for open-top derinding and defatting of meat cuts of boneless pork shoulders and legs (only derinding).

The OTB50 performs highly effectively, precisely and powerefficiently and achieves a perfect skinning result. The symmetrical sides of the machine, together with the recessed front panel, allow operators to stand closer to the skinning mechanism.

An outstanding feature of the OTB50 series is the Variable Frequency Drive that can be used to control the speed of the tooth roll, to adjust to a specific application or operator skill level.

Side panels without control levers or handles ease the integration into any processing line. The system can be operated left-sided or right-sided without compromising operator ergonomics.

To start the skinning process, the operator utilizes a flat foot treadle, allowing to take an easy and comfortable position while operating the machine.

For skin trim collecting purposes, Marel’s OTB50 offers plenty of space at the rear end of the machine for a wide variety of trim conveyors. The design also allows standard skin boxes to be pulled from the front end of the machine.
