Overview

The course will be presented in English.

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 through an exercise run on a pilot extruder.

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.

PDF notes directly relevant to the presentations will be provided prior to course commencement. Participants can order a more detailed hardcover text book at additional cost.

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.
