Hygienic design

THIS COURSE IS A DEVELOPMENT OF THE ADVANCED COURSE ON HYGIENIC DESIGN

In this challenging and comprehensive 3-day Hygienic Design course, all relevant topics for producing food safely with a to be designed or existing device or entire production line are covered in depth. The course focuses on the collaboration between machine designer and user, and is constantly adapted to new developments.

GOAL:

1. Understanding the necessity of hygienic design (cleanability to microbial level)

2. Evaluating the purchase of equipment for microbial cleanability

3. Designing, outsourcing, and supervising projects related to hygienic design (incl. outsourcing hygienic welding)

4. Recognizing, signaling, and reporting non-hygienic situations

5. Motivating production and technical staff to work hygienically

This course fits into a cycle covering Zoning - Building (including interaction with machines), CIP cleaning, and, where relevant, Dry processes.

EXPERIENCED TRAINER

Burggraaf & Partners has specialized in advising the food industry and pharmaceuticals since 1993, and the machinery builders in this field. The firm is active in virtually all sectors (bakery, fruit and vegetables, dairy, meat, beverages, biotechnology) and has provided dozens of training sessions and courses in this area together with various organisations.
