Course description

The Dry Processes working group of the EHEDG (European Hygienic Engineering & Design Group) has published seven guidelines. This course provides a clear overview of the most important topics from these guidelines. 

Companies affiliated with OOM or OTIB may be eligible for a contribution towards the costs. For more information, see www.oom.nl, respectively wij-techniek.nl.

TOPICS

1. Zoning

The sense and nonsense of hygiene measures based on risk analysis.  Wet, dry, and controlled wet cleaning of equipment and spaces.

2. Dry cleaning

To what level should cleaning be done: Allergen-free or low allergen? What dry cleaning techniques are available? Effect of dry cleaning compared to other wet cleaning techniques.

3. Specific design rules for Dry Processes

The materials to be used, surface roughness, magnets, sliding behavior, couplings, flexible connections, and seals.

4. HD - discharge systems

The hygienic design of discharge installations for big bags, sack goods, and bulk trucks with a case study on discharge cabinets. 

5. HD - conveying systems

All known conveying systems for dry products compared. Screw conveyors (trough, pipe, flexible), jacob's ladder, belt conveyors, reddler, aeromechanical, vibrating chute, and pneumatic conveyors (under and overpressure, various types).

6. HD - valve

Hygienic design criteria for butterfly valves, slide valves, pinch-off valves, ball segment valves, ball valves, cone valves, rotary valves, and changeover valves.

7. HD - building

The minimum design criteria for spaces to be cleaned dry.

8. Wet & Dry separation

Concept for dumping dry powders that are dissolved. Where the separation between wet and dry cleanable parts occurs.

9. CIP-cleanable components

The state of the art for EHEDG certified components that are cleanable with CIP (automatic cleaning).

10. Fluidized bed & spray dryer

All HD rules applied to a fluidized bed and spray dryer. 

11. Case studies

Depending on the participants' interest: mixer, rotary sieve, drum dryer, and/or bagging installations.
