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, and New Zealand for 20 years. This course has been presented annually in Norway since 2015, with excellent feedback from participants.
We appreciate support/sponsorship from companies involved in providing equipment and services relevant to extrusion or aquafeed. Download information on sponsorship opportunities.
The course will be presented in English.
pdf information brochure will be available for download soon.
This 3-day course covers the principles of extrusion, the design of extrusion processes for aquatic feeds, as well as how the formulation interacts with the extrusion process. Principles learned will be demonstrated using the extruder in at the Fish Nutrition and Physiology Laboratory (Unidad de Nutrición y Fisiología de Peces).
The program provides a good background in general extrusion technology, but is specifically directed at aquafeed extrusion. The course is relevant to both single and twin screw extrusion technology.
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.

The main presenter is Mr Dennis Forte, a chemical engineer with extensive experience in extrusion processing and die design, including aquafeed production. Dennis has worked with a wide variety of companies and extruded products.
Mr Gordon Young is a food process engineer who has worked in extrusion technology in both University research and with private companies. He is also experienced in a wide range of other food processing technologies, including specific expertise in drying technology and thermal processing.
Who Should Attend?
This program is relevant to technical staff interested in the formulation of extruded aquafeeds and the use of extrusion technology for aquafeed production. 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.
Participants must organise their own accommodation.
What participants need to bring
For safety and hygiene reasons, all visitors are requested to comply with the following clothing protocols on the second day for the demonstration:
- flat, fully enclosed footwear, or steel-toed industrial safety shoes, are to be worn
- full leg coverage (ie trousers) is required. Skirts, short pants or 3/4 length trousers are not suitable
- you will be asked to remove watches and all jewellery other than solid bands.
We also suggest usual items such as notepad, pen or pencil, and highlighter.
Fees, less a 15% handling charge, will be refunded if participants cancel their registration prior to the closing date for registrations. Fees will not be refunded after that date, but a substitute participant will be accepted at any time.
FiE reserves the right to cancel or postpone the course if necessary (e.g. due to insufficient registrations). In this case a full refund of fees will be available. FoodStream’s Liability is limited to the registration fee only, and FoodStream cannot be held liable for air fares, accommodation, or other related expenses.
