A Decade of Spinning on

The Same Bearings!

Koninklijke Vezet BV, the market leader in Europe in fresh food
processing, is a fan of innovation and technology. Not in the sense of
a goal to achieve, but as a means of providing their customers with
the best possible service. Notably, the production team is expressly
involved in any innovations.

Vezet processes a huge variety of produce. This is done on largely high pressure air knife
automated production lines, with a minimum of manual labour. Innovative which cleans all residual
