Co-rotating screws and/or extruders are used in many branches of industry for producing, preparing and/or processing highly viscous materials. They find a wide variety of applications especially in the plastics, rubber and food industries. This book provides basic engineering knowledge regarding twin-screw machines; it lists the most important machine-technical requirements and provides examples based on actual practice. Better understanding of the processes is emphasized as this is a prerequisite for optimizing twin-screw designs and operating them efficiently.
Revision of The Extruder Book published in 2001. New images, updated materials.If you have an extruder and aren't sure what to do with it, Daryl's comprehensive book updates his best-selling first edition. You'll discover tips for setting up your studio, supplies you'll need to make extruding easier, and accessories that will help you with more complicated extrusions. Your extruder set-up can be as sophisticated as any pros with less effort than you think.Since his first edition, Daryl has expanded his offering of projects and you'll discover sixteen great demonstrations which will increase your confidence and challenge your skills. From using simple dies to constructing projects from multiple-part dies, Daryl carefully leads you step-by-step through projects that run the gamut of complexity. As you master each process, your imagination will inspire even more ideas to take on.If you don't already have an extruder, don't worry. Daryl describes what's on the market today from major manufacturers, but he also includes plans on how to make your own extruder from parts you can gather at a local home center. But the essence of an extruder is the die and here is where Daryl showcases his expertise. From altering stock dies to creating complex multi-part dies, you'll find instructions for making unique dies unlike any you can buy on the market.To illustrate just how versatile the extruder is, Daryl showcases the work of dozens of potters and artists using the extruder in their work. You'll be inspired by the creativity and you'll see that your extruder is capable of much more than just making test tiles or strap handles.
The result of years of experience by experts in extrusion technology, Extruders in Food Applications brings together practical experience and in-depth knowledge of extrusion cooking technology. This concise reference summarizes basic considerations for the application of extrusion technology to food industry processes and focuses on the various types of extruders available for a growing number of food applications.Chapters compare and describe the different types of extruders and their functions, including characteristics, advantages and disadvantages, and applications, providing a wealth of information about dry extruders, interrupted flight extruder-expanders, and single screw and twin screw extruders. The effects of preconditioning on the raw material and of extrusion on the nutrients of products are covered as well. This book is a valuable source for the technical and practical application of extrusion and will be useful for the selection of the proper equipment for this technology.
