Hygienic building

This course gives a reason for the necessity of hygienic design. It also gives engineering guidelines to ensure that buildings, building related aspects and also accessibility of equipment (when integrated within the plant layout) are designed in a way that aspects of the process operation, cleaning and maintenance comply with hygienic design standards. It details requirements related to plant enclosure, including hygienic zoning, building structures and elements (from floor to ceiling) as well as process line installation. It contains the main aspects of EHEDG Guideline no. 26 and 44, including the latest developments regarding zoning, HVAC and cabling.

14. Case studies

  • A ready meal factory is shown on iPads as base for risk analysis and the need for zoning.
  • During the whole course a baby food plant (dry powder handling, recipe formulation, wet processing, spray drying and bag filling) is worked out step-by-step for proper zoning and HVAC; in the last lecture (no.13) the actual realisation is shown in a video.
