This short course is presented by FiE in conjunction with FoodStream and the Faculty of Natural Resourses, Catholic University of Temuco, Chile.

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 almost 20 years. Programs in Europe commenced in 2015, with excellent feedback from participants.

A Food & Feed Dying Technology program is also being offered on 7 & 8 November - additional discount for those attending both courses.

Day 2 of this course is Sponsored by


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

The course will be presented in English, with simultaneous translation into Spanish.

This 3-day course covers the principles of extrusion and the design of extrusion processes for pet foods, as well as how the formulation interacts with the extrusion process.  Principles learned will be demonstrated using the extruder in the FôrTek pilot plant.

The program provides a good background in general extrusion technology, but is specifically directed at manufacture of extruded pet foods. 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 science – Ingredients & Recipe design

  • Product expansion

  • 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 petfoods and aquafeeds and the use of extrusion technology for petfood and aquafeed quafeed 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. The course will be presented in English, with simultaneous translation into Spanish.


Monday to Wednesday, 11 - 13 November 2019

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 4:00 pm on the final day.
