Flow diversion in aseptic processing and packaging systems: how guidelines allow avoiding bad design

Flow diversion is a matter of concern for Food Hygiene in Aseptic Processing and Packaging Systems. The relevant standards and guidelines have been examined: since the Aseptic Processing is a widely used and well-established technology, there is quite a lot of available material. The flow diversion topic is also addressed, particularly by EHEDG Guidelines. The correct choice of the temperature probe, also plays an important role in the successful design of a flow diversion system. A procedure, which also includes simple simulation tools, has been developed in order to properly design the flow diversion device. A real case study is also reported. This research reaffirms that it is necessary to have more regard to standards and guidelines and also shows how guidelines allow avoiding bad design.
