Extrusion workshop: Practical extrusion and diet development for extrusion processing

Peter Hutchinson, Director, E.N. Hutchinson, Auckland, New Zealand

The workshop will comprise two sessions: Practical Extrusion and Diet Development for Extrusion Processing. Practical Extrusion will focus on feed extrusion principals such as screw designs and profiles; die design, extruder trouble shooting, drying and cooling. The session on practical nutrition will look at diet development for extrusion processing and cover such topics as sourcing locally available material, matching extruder profile to formulation, die design in relation to species, high retention (water stable) diets, optimizing the pellet through extruder settings (cook, minimizing nutritional damage, stability and density), basic quality control, post coating and density control through coating and dryer design. Practical problem solving is at the heart of the workshop and Peter will be joined by an international panel of extrusion experts to answer your extrusion questions.
