EHEDG Subgroup “Conveyor Systems”<br />
Jon J. Kold, e-mail: jk_innovation@yahoo.com<br />
In January 2011 the EHEDG Subgroup “Conveyor Systems”<br />
became active.<br />
The group has collected a huge amount of material and is in<br />
the process of editing the content.<br />
The purpose of the Subgroup is to prepare a new EHEDG<br />
Guideline on the hygienic design of conveyor systems to be<br />
used in food manufacturing or processing. The Subgroup<br />
consists of approximately 15 professionals from companies<br />
and institutions. This underlines the industry’s broad interest<br />
in the subject.<br />
Conveyor systems are widely used in food manufacturing<br />
for moving raw materials, processed food and packaged<br />
products. The upcoming guideline is primarily aimed at<br />
conveyors used in high risk areas, i.e. the processing of<br />
non-packaged foods in direct contact with the conveyor or<br />
transported in open boxes.<br />
There are several reasons to reduce the hygiene risk by<br />
applying hygienic design to conveyor systems.<br />
The guideline may be used as a communication tool<br />
between purchasing companies and suppliers making sure<br />
that new conveyors comply with hygienic requirements<br />
specification.<br />
The Subgroup “Conveyor Systems” is chaired by EHEDG<br />
Denmark who have previously elaborated a guideline for<br />
hygienic deign of conveyers for the food industry.<br />
Hygienic design of conveyor systems<br />
The hygienic design of conveyor systems is complex and<br />
demanding. Many solutions with regard to function, design,<br />
cleanability and service of the equipment must be considered<br />
thoroughly.<br />
The equipment should be as open as possible for easy<br />
accessibility and cleaning. The number of guards should<br />
be minimised to what is necessary for reasons of safety<br />
and should not prevent efficient cleaning. Guards should<br />
be removable during cleaning/disinfection, either through<br />
opening or by unhinging.<br />
Topics which are being dealt with during the working period:<br />
• Different types of belts<br />
• Lateral guides for belts<br />
• Lateral guides for product<br />
• Drive stations<br />
• Drum motors<br />
• Gear motors<br />
• CIP cleaning systems<br />
Time schedule<br />
The new guideline is intended to be finalized within the next<br />
12 – 18 months.<br />

EHEDG Subgroup “Dry Materials Handling”<br />
Karel Mager, e-mail: karel.mager@givaudan.com<br />
When the EHEDG started in 1989 most of the available<br />
knowledge on hygienic design was about liquid handling and<br />
liquid processing equipment.<br />
In the following years a couple of documents about test<br />
methods and design principles concerning this topic were<br />
published.<br />
In the area of dry particulate materials (powders) there was a<br />
need for similar documents: design principles and guidance<br />
for hygienic engineering for the safe processing of dry<br />
particulate materials.<br />
The subgroup started in 1998 and since then has published<br />
eight documents.<br />
Published guidelines<br />
• Doc. 22 General hygienic design criteria for the safe<br />
processing of dry particulate materials (2001)
