Knife peeler MS

The MS knife peelers 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 a large number of 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.

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 peels the potatoes perfectly with no flat peeling effect. Partly due to this, the peeling yield is higher than that of other machines."

  • Mr. Henk van Raalte, Schaap Holland B.V., The Netherlands

Product specification

Washed (round) tuberous products of a diameter of between 1 3/16″ and 7 3/32″. There must not be any stones or sand residues in or with the product.


The MS-20 knife peeler has a peeling waste capacity of 1,300 to 1,500 lbs per hour. With 40% waste, the input capacity is therefore 3,300 to 3,850 lbs per hour. When polishing a pre-peeled product (waste percentage of approx. 20%) the input capacity is consequently between 6,600 to 7,700 lbs per hour.
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.
