Multi-disc-peeling machines MSS (8000 ff., 8040 ff.) 

    convertible to carborundum and blade-type and onion peeling machines, 
also available with special design discs. Continuous development of 
the machines.


Construction and mode of operation: numerous small peeling discs (blade, carborundum or onion peeling discs), arranged on a horizontal plane with a moving conveyor unit. Very smooth peeling results are possible! With required additional equipment, the machines are able to operate without generating waste water in almost all areas of use. - For the peeling of potatoes and many varieties of tubers and root vegetables (even partially cooked), and some varieties of fruit, including tropical fruit. Gentle peeling procedure! 

The universal peeling machines are quickly convertible to carborundum, blade-type and onion peeling machines. Our topping and tailing machines TT will remove tops and tails of the onions: please see section D.-15.

Blade-type version machines are also used as re-peelers for still-blemished steam-peeled potatoes.

Some critical products can be peeled with specially designed discs, developed by us.

Continuous universal-multi-disc peeling machines (MSS) are distinguished by an extremely gentle peeling procedure, greater flexibility in the exchange of various peeling tools, and by a peeling process without the generation of waste water. The speed of peeling discs and conveying equipment is continuously adjustable.

the machines with the other mentioned peeling discs. The machines can therefore be used as 
blade-type, carborundum or onion peeling machines. In this respect all below-mentioned machines 
are universal peeling machines.

2.5.2 BU series
2.5.3 CU series


Explanation of the series codes for the machines:

  A = 1 peeling unit
  B = 2 peeling units
  C = 3 peeling units
  M = blade-type version (installation possible of all other peeling discs)
  K = carborundum version (installation possible of all other peeling discs)
  KM = combination carborundum-blade-type version (installation possible of all other peeling discs)
  Z = Onion peeling version (installation possible of all other peeling discs)
  U = Universal version (with all aforementioned peeling discs, without special design peeling discs)

Performances may vary greatly according to product, season, quality of raw produce, desired degree of cleaning 
and area of usage. 
Feeding e.g. prepeeled potatoes will increase the machines' performance considerably.

A number of special design peeling discs are available, including peeling discs especially for the peeling of root 
celery, as well as other custom-made discs, for instance for the re-peeling of still blemished, steam-peeled potatoes. 
We continually develop further discs for different areas of application!

The brochure of these machines can be found under P117.

Pictures (among other things), of various produce peeled by universal-MSS-machines

Potatoes Carrots Celeriac Radish Kohlrabi Mangos
Nectarines Kiwi Avocado Pomegranates Papayas Pineapples
Melons Oranges Apples Onions Shallots  


1. Blade-peeled potatoes 


Surface of peeled potatoes after blade-peeling with universal-multi-disc peeling machine MSS-AM
variety: Cilena. Notice the distinct blade-like cut, similar to a housewife's hand peeled potatoes



2. Carborundum-peeled potatoes


Surface of peeled potaotes after carborundum-peeling with universal-multi-disc peeler MSS-AK, variety: Cilena

The surface may be very smooth due to "micro-fine grain peeling", smoother than is visible in these pictures. A very smooth surface 
can be achieved, very close to the smooth surface of steam-peeled potatoes.

MSS-machines are able to peel very gently, which ensures a longer shelf-life for the finished product.

3. Carrots, cut into cubes, then peeled "round":

The peeled carrot pieces look like "pommes parisiennes". They can also be used as a snack.

Exceptionally good (sweet) taste e.g. the species "Sugarsnax 54 F1", "Primecut F1" and "Topcut 93 F1" from the 
company Nunhems.
