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. This course was first presented in Norway in 2015, with excellent feedback from participants. A program in Food and Feed Drying Technology is also being offered on 11 & 12 April, and a Pet Food Extrusion Technology course from 8 to 10 April.
We appreciate support/sponsorship from companies involved in providing equipment and services relevant to extrusion or aquafeed. Download information on sponsorship opportunities.

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 the Centre for Feed Technology pilot plant.
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
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 course will be presented in English.
Monday to Wednesday 15 to 17 April 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 4:30 pm on the final day.

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. Some options include:
a. Thon Hotel Ski. Special course price NOK1215 per night including breakfast. Book directly with the hotel using booking code "NMBU"
b. Reenskaug Hotel Drøbak. Special course price single room with breakfast NOK1090 per night. Book direct with the hotel and say you are attending the course at NMBU.
c. Hotels in Oslo (within commuting distance – see below).
Getting to the Venue
The bus, train and public transport in general is administered by Ruter in Oslo and Akershus. A bus ticket costs between 50 – 100 NOK depending on how far you are travelling, and can be bought directly on bus.
The train to Oslo is called “Skøyen” and leaves from Platform 1 in Ås station 51 minutes past every hour, and arrives in Oslo 30 minutes later. The train back to Ås is called ”Moss” and leaves 18 minutes past every hour, usually from platform 9 or 10 in Oslo Central Station. Make sure to keep tickets/receipts of all kind of transportation, while you are on board. Random checks are performed by MInistry of Transport and a fine of 900NOK or more may be enforced in case of absence of proof of ticket.
You can buy tickets from the ticket machine in the station, which accepts coins and bank cards only. You can also buy tickets on board the train, but it will cost 20Nok extra for each trip. The train tickets are also valid on public buses and are valid for more than 1.30 hours, so with a train ticket from Ås to Oslo for example you can also have a bus ride in Oslo for some time. Similarly with the return ticket to Ås you can take the bus back to Pentagon with the same ticket.
The monthly card will take you all over Oslo and Akershus by all means of public transport for 920 NOK a month, and is the best option if you intend to travel every day. For single trips the prices are 70 NOK one way to Oslo. There are no student discounts on this route.
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 provided with a visitor dust coat and hair net
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 10% 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.
We reserve 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.
