Food Extrusion Technology, Europe (Switzerland)

  • HES-SO Route du Rawyl 64 1950 Sion 2 Switzerland (map)

This short course is presented by FiE in conjunction with FoodStream and the University of Applied Sciences and Arts Western Switzerland Valais (Hes-So Valais), Institute of Life Technologies.

FoodStream is an Australian company which, working with Gordon Young of FiE and extrusion specialist Dennis Forte, has been presenting extrusion training in countries including Australia, Thailand, Norway, and New Zealand for over 20 years. 

This course has been held annually in Switzerland since 2018, with excellent feedback from participants. A program in the Design of Food Extrusion Dies is also being offered on 13 & 14 February..

Day 2 of this course is Sponsored by


We appreciate support/sponsorship from companies involved in providing equipment and services relevant to food extrusion operations.


The course will be presented in English.

Being independent of all extruder suppliers, we offer unbiased training based on the science and engineering of extrusion. This 3-day course covers the principles of extrusion, the design of extrusion processes for human foods, as well as how the formulation interacts with the extrusion process. Principles learned will be demonstrated using the extruder in the Hes-So Valais  pilot plant.

The program provides a good background in general extrusion technology, but is specifically directed at extrusion of human foods. The course is relevant to both single and twin screw extrusion technology, and all types of extruded foods - breakfast cereals, snacks, texturised proteins, pasta, etc.

The course will cover topics from the basics of extruders and their configuration, through what is happening chemically and physically inside the extruder barrel, to an understanding of extruder dies and extruder instability.

Topics covered include:

  • Principles of extruder configurations (single and twin screw)

  • Role of rheology in extrusion

  • Die types and effects, die design

  • Extrusion chemistry – Recipe design

  • Product density control

  • Preconditioning for Extrusion

  • Causes and effects of extruder instability

  • Screw, barrel, and die-plate wear

  • Extrusion troubleshooting

Examples in product formulation and the design of extrusion processes will be included to demonstrate application of the theory. Principles learned will be applied during the practical demonstration on Day 2. Important aspects of peripheral systems (eg raw materials pre-processing, preconditioning) are also covered.

Handout notes directly relevant to the presentations are included in the registration fee. Participants can order a more detailed hardcover text book at additional cost.

*Course program may be subject to minor changes.

Who Should Attend?

This program is relevant to technical staff interested in the formulation of extruded foods and the use of extrusion technology in food processing. The program takes participants from the basics of what extrusion is and what it can do, through to a detailed understanding of the design of formulations and processes, and the operation and troubleshooting of extrusion systems.


Monday to Wednesday, 10 to 12 February 2020

Tea/coffee will be available from 8:15 am on the first day, ready for the program to start at 8:30 am. Presentations will conclude by 4:30 pm on the final day.
