The course provides knowledge of and insight into the hygienic design of equipment and processes for the food, feed and pharmaceutial industry, to better fulfil the wishes of purchasers and retailers. These include minimising down time, maintenance, cleaning costs and environmental impact, but also efficient cleaning, optimal product safety and constant product quality. The design should comply with present legislation and standards, but can also anticipate future changes.
The course is meant for mechanical engineers, constructors, draughtsmen, project managers and sales-engineers, active with machine building for the food industry, including the engineering offices. Participants can originate from different sub-branches.
The course is also excellent for the technical and quality assurance staff of the food, feed and pharmaceutial industry itself.
Previous training and working experience
The participants should have a minimum of two years of relevant practical experience. Participants with equivalent training or experience may be able to participate after consultation with the course director.
The course duration is 4 days, starting at Monday 27 November at 13.30 and ending Thursday 30 November at 12.30. There is an optional part with a choice out of two subjects Thursday 30 November afternoon.
Form and content
The course is given from a very practical viewpoint. The theoretical fundamentals of the different subjects are presented in a short and concise way, continuously relating to practice by means of examples on video or pictures or samples. By studying cases of equipment present and in drawings on iPads the participants gets the opportunity to apply the knowledge. The course gives you tools to solve hygienic problems within your own organisation. Because of the small groups the course is very interactive.
The cost of the course is Euro 2,295 ex. VAT, including handout, coffee, tea, lunches at full days, three times dinner and travelling during the Course.
When a company is EHEDG member its employees are entitled to a Euro 200 reduction. This does not apply to individual EHEDG members.
The optional part, including hand-out and lunch, costs an additional Euro 350.
Via email to Burggraaf & Partners before 20 October 2017. In case you need a visa, please register before 6 October 2017.
