From an exclusive construction company to market leader in seedprocessing equipment

Seed Processing Holland has its roots on the grounds of Royal Sluis (now part of Monsanto). IJsbrand van Dok and Karel de Boer started their own construction company there and manufactured and repaired parts for seed processing machines – exclusively for Royal Sluis.


to the extensive work and the already growing seed industry, there was soon a need for a larger workspace, which led to a move to ” Het Waaigat ” (1972) and again six years later to the current location of Seed Processing Holland; Zoutketen in Enkhuizen..


Expansion work in 1983 caused a major fire to burn the entire company to ashes. All that could be saved were the drawings. The reconstruction of the building also meant a new start: from now on van Dok & de Boer would operate worldwide.

Van Dok & de Boer built a worldwide customer base for more than 10 years, until they decided in 1992 to separate their ways. Van Dok & de Boer became history and Processing Holland B.V. was born.
