EHEDG NZ has deployed its NEW Hygienic Design Interactive Educational Display known as the IED, used at several of its most recent events, firstly at Food Tech Pack Tech 2023. Then at the Nov 2023 Hamilton AHDC (Advanced Hygienic Design Training Course) held at the WINTEC Long Room, also at the last AHDC held in Christchurch’s Novatel Cathedral Square in March 2024 and most recently at the NZIFST Annual Conference in Hamilton Distinction Hotel.
Whilst it is not your usual IED it has been a huge success, delivering an explosion of interest from participants who can now see firsthand what features make a Good Hygienic Design OR NOT!
The display was designed by our very own NZ based EHEDG Certified trainer Shane Mason, who’s day job is Engineering Manager of PENTAIR SUDMO based in Hamilton NZ. The construction was also executed by PENTAIR under Shane’s close supervision and whilst materials and most labour were paid for by EHEDG, it was also generously subsidised by PENTAIR, again a great measure of the support we get from a long standing EHEDG Member Since 2000.
Some of the key features of the display are the three prominent hourglass type, pivoting coupling displays, that demonstrate how some of the most commonly used and supposedly Hygienic pipe couplings compare side by side with the aftermarket EHEDG compliant retrofittable gasket versions, see close up UV lite examples below. This Example shows an IDF type coupling to AS 1528.2 with a standard T-Ring seal in the top joint and an EHEDG compliant and certified aftermarket Composite T-Ring seal in the lower joint. Under the UV light the crevice created with the standard T-Ring seal, can be clearly seen. This highlights a serious cleanability issue, whereas the EHEDG Compliant T-Ring shows no product hang up, so very cleanable.
Other EHEDG compliant examples are shown for Tri-Clamp and RJT Variants. Other fabrication examples on the display include ways to ensure good drain-ability of external surfaces, Dead leg Do’s and Don’ts for cleanability and avoiding bugs traps with simple common sense designs and techniques.
How to identify Good welds from Bad! And many other commonly used features used in everyday Hygienic applications, but not always executed effectively.
Come and join one of our EHEDG Advance Hygienic Design Training courses or events we are attending to see this spectacular display and interact with it using the tilting coupling mechanism and UV light provided, to highlight the areas you should be concerned about.
