Test peelings with various mechanical peeling systems in our peeling test center: with onions,
potatoes, carrots, various turnips, celeriac, parsnips, beetroot and other tubers and root vegetables, and some fruit.

The aims of our peeling test center are to demonstrate to everyone who has to peel tubers and root vegetables the advantages of our large range of peeling machines and to develop the logical set-up of peeling lines together with interested parties. 


Peel your own raw produce (tubers, root vegetables, some fruit, tropical fruit etc.) in the DORNOW peeling test center! Certain products such as waxy potatoes, beetroot etc. can also be peeled after cooking. Also tests can be made with the above presented onion top-and-tail cutting machine for removing leaves and roots.

If you are interested in visiting our peeling test center or would like to carry out a “remote diagnosis” (see below), please fill in the accompanying reply sheet and arrange an appointment with us.  

Would you like to save time? Then we can give you the chance to test the results of your peeling system and get to know our latest peeling technology without spending much time on it – by means of a so-called “remote diagnosis”. Just send us the produce you would like us to peel after a short telephone consultation with us. Just 10 kg is often enough. We will draw up a report of the results with details, amongst other things, on peeling waste as well as photos. If you wish, we can also send the peeled produce back to you.  

The cost of a demonstration or a “remote diagnosis” is EUR 175 plus VAT/sales tax. - This amount will be offset against the
purchase price of any machine ordered. In case several days will be necessary, additional EUR 175,-- plus VAT per day
will be charged (for personnel, cleaning, etc.).
Before visiting or before sending us the produce that has to be peeled for “remote diagnosis”, please give us a call so we can
discuss the demonstration peelings in detail first.
