A Unique Approach to Applied Extrusion Training

We have been presenting “Food and Feed Extrusion” courses in Australia and internationally since 1996. That course, while very practically oriented, is dominated by lecture-style presentations, supported by a single practical demonstration.

This “applied” extrusion course, which we have presented in Thailand since 2011, takes a different approach, providing participants with an understanding of the theory of the extrusion process, combined with pilot plant exercises demonstrating how the principles are applied across different products and extruder types.

Introductory sessions cover relevant extrusion theory, followed by discussion in which the product formulation, and screw configuration/ process parameters are “designed”. Then we go to the pilot plant and make the product – running the formulation with the designed screw profile.

While a limited number of specific products can be made during the program, the range is selected to demonstrate the principles and issues involved across the range of types of extruded products – including expanded snacks and breakfast cereals, pastas and third generation snack pellets, textured vegetable proteins, pet foods and aqua-feeds. Five different products are made on three different types of extruder (long barrel single screw, twin screw, and collet extruders) during the three-day course.

Topics covered include:

  • Principles of extruder configurations (single and twin screw)

  • Role of rheology in extrusion

  • Die types and effects, die design

  • Ingredients used in extrusion

  • Causes and effects of extruder instability

  • Screw, barrel, and die-plate wear

Exercises in product formulation, screw configuration and process design include:

  • Textured vegetable protein, TVP (similar operation to pet/fish feeds)

  • Direct expanded breakfast cereal

  • Third generation snack pellet

  • Co-extruded expanded snack

  • High moisture meat analogue

These exercises are chosen to reflect the range of processes/ configurations used across both human food and animal/fish feed applications.
