Sormac Knife Peeler MS

The Sormac knife peelers MS are suitable for continuous peeling of pre-washed or pre-peeled root products, like potatoes, red beet, celeriac, etc. The produce to be peeled is conveyed by a transport auger through a horizontal, rotating drum.

The inside of this drum is equipped with many knives. The dwell time and peeling effect can be controlled by varying the RPM of the drum and the speed of the transport auger. The special shape of the drum and the way the knives are positioned effectively avoids the produce from being flat peeled.

The peeling waste is separated from the peeled product immediately and ejected by the rotating drum. The waste can be collected for removal in a crate or waste transporter via the waste funnel at the base of the machine.

Potato knife peeler type MS-20 - Sormac

In the model MS-20/Combi, potatoes that have not been pre-peeled can be peeled as normal. The Combi-drum has several pre-peeling plates that replicate the effect of pre-peeling. The final peeling quality is equal in every respect to the MS-20 knife peeler.

The MS-20 knife peeler has a peeling waste capacity of 600 to 700 kg/h. With 40% waste, the input capacity is therefore 1,500 to 1,750 kg/h.

When polishing a pre-peeled product (waste percentage of approx. 20%) the input capacity is consequently between 3,000 to 3,500 kg/h. The capacities of the MS-30, MS-20/Combi, and MS-10 are approx. 150%, 80% respectively 50% of the capacity of the MS-20.

  • Waste transportation system
    Excentric type EAP waste pump.
