Food & feed drying technology
Overview
|
Drying is one of the most common operations in food and feed production. It is used across virtually every sector/commodity. It is critical to the quality and/or functionality of many products, and it is one of our most energy-intensive process operations. Yet it is often poorly understood and inefficient.
This short course in Drying Technology combines the practical perspective of experienced industry professionals with the in-depth technical knowledge of drying processes. The course will start by explaining water activity in products, and how it relates to both the quality/preservation of the product and the efficiency of the drying process. We will then go on to the basics of drying theory and how this theory relates to practical application. Different types of drying systems will be explained. Principles of psychrometrics will be combined with heat & mass balance techniques to analyse and design drying processes, demonstrated using practical examples. On Day 2, more advanced drying concepts will be explained, using practical examples to demonstrate how drying curves can be modeled and predicted based on real data. Quality issues in dried products will also be discussed in more detail, and a case study presented to show how existing drying processes can be improved. The program will finish with a series of case studies about different drying technologies. This course is about understanding the drying technologies used commonly across the food and feed industries - and how we can use that understanding to improve current processes and products, or design/select new systems that are both effective and efficient. |
This short course is presented by FiE in conjunction with Australian company FoodStream and ExtruAfrica. Foodstream has been presenting extrusion training in countries including Australia, Thailand, Norway, Chile and New Zealand for over twenty years. |
Who should attend?
|
This program provides value to those planning or running extrusion operations - from engineers, managers and line supervisors, to extruder operators. Note that many topics are quite technical in nature, but we start from basics, assuming no prior knowledge, so that participants can take understanding at a level appropriate to their requirements.
