July 30, 2017

As the people are the heart of Tummers, R&D is the backbone. Tummers is continuously working on improving their machinery, the process, service or other aspects to apply to the demands of the market, within the Tummers Group.

Tummers is not improving just to improve, but improving based on feedback from its customers.

Once in a while this contains a drastic development like the ZicZac brusher, Switcher, Autotrax or washer/destoner, but mostly this contains subtle improvements on already existing processes or machinery.

These are the most recent developments in the range of potato processing machinery of Tummers:

  • Redesigned Tummers washing line

  • UV-treatment on the Roller dryer.

    Tummers added UV-treatment to the Roller dryer. This is used for disinfection or de-activating the bacteria on the potatoes. Bacterial DNA bonds will be broken and can’t reproduce so the colonies die.
