Dry Materials Handling

Chairman:
Gabrie Meesters

E-Mail: gabrie.meesters@dsm.com

When EHEDG started in 1989 there most of the knowledge available was about liquid handling and liquid processing equipment. Also the design principles were known but not written down as practical guidance documents for engineers in the food industry. In addition, there were no standard test methods to establish the cleanability, pasteurisability and sterilisability of equipment. In the following years a couple of documents about test methods and design principles where published.

In the area of dry particulate materials (powders) there was a need for similar documents: design principles and guidance for hygienic engineering for the safe processing of dry particulate materials.

The Working Group started in 1998 and has published several documents since then.

Published Guidelines:
Doc. 22 - General hygienic design criteria for the safe processing of dry particulate materials (2014)
Doc. 26 - Hygienic engineering of plants for the processing of dry particulate materials (now integrated into Doc. 44)
