Many variables exist in the food extrusion process. While things like barrel temperature, screw speed, and water content are frequently adjusted, changing a screw geometry is a variable seldom touched by developers due to the complexity and unpredictability that may result. However, changing a screw geometry is one aspect that can rapidly change your process from something difficult to control to a process that runs smoothly and hits product targets all the time. In this webinar, we will discuss the different types of geometries commonly available for single and twin-screw extrusion and how you can begin to change them to unleash their potential for product and process development.
Learning Objectives:
- Understand what type of screw to use in single screw extrusion of different pet food and aquafeed products.
- Be able to identify different elements used in twin-screw extrusion and what the purpose of each one is.
- Know the steps needed to design a twin-screw profile targeted toward snack foods and meat analogs.
- Predict what elements will be needed and where to develop extrusion products faster.
