In addition to the usual benefits of heat processing, extrusion offers the possibility of modifying and expanding the functional properties of food ingredients. Designed for both the active and future food scientist, this book is an exciting addition to a creative and ever-evolving field.

The second edition of Extrusion is designed to aid operators, engineers, and managers in extrusion processing in quickly answering practical day-to-day questions. The first part of the book provides the fundamental principles, for operators and engineers, of polymeric materials extrusion processing in single and twin screw extruders. The next section covers advanced topics including troubleshooting, auxiliary equipment, and coextrusion for operators, engineers, and managers. The final part provides applications case studies in key areas for engineers such as compounding, blown film, extrusion blow molding, coating, foam, and reprocessing. This practical guide to extrusion brings together both equipment and materials processing aspects. It covers basic and advanced topics, for reference and training, in thermoplastics processing in the extruder. Detailed reference data are provided on such important operating conditions as temperatures, start-up procedures, shear rates, pressure drops, and safety. A practical guide to the selection, design and optimization of extrusion processes and equipment Designed to improve production efficiency and product quality Focuses on practical fault analysis and troubleshooting techniques

Offering an engineering perspective and the latest information on the application of this rapidly expanding technique, this practical book covers the technology, engineering, materials and products, as well as economic and ecological aspects. In addition to the theory, it also utilizes case studies that can easily be put into industrial practice. Each step of the process is discussed in terms of sustainability, and all data complies with the EU and FTA environmental regulations.

The first edition of Pharmaceutical Extrusion Technology, published in 2003, was deemed the seminal book on pharmaceutical extrusion. Now it is expanded and improved, just like the usage of extrusion has expanded, improved and evolved into an accepted manufacturing technology to continuously mix active pharmaceutical ingredients with excipients for a myriad of traditional and novel dosage forms. Pharmaceutical Extrusion Technology, Second Edition reflects how this has spawned numerous research activities, in addition to hardware and process advancements. It offers new authors, expanded chapters and contains all the extrusion related technical information necessary for the development, manufacturing, and marketing of pharmaceutical dosage forms. Key Features: Reviews how extrusion has become an accepted technology to continuously mix active pharmaceutical ingredients with excipients Focuses on equipment and process technology Explains various extrusion system configurations as a manufacturing methodology for a variety of dosage forms Presents new opportunities available only via extrusion and future trends Includes contributions of experts from the process and equipment fields

Extrusion cooking is an ideal method for manufacturing a number of food products from snacks and breakfast cereals to baby foods. However, as a complex multivariate process it requires careful control if product quality is to be maintained. Edited by a leading authority in the field, and with an international team of contributors, this important collection reviews the key factors affecting quality and how they can be controlled in manufacturing a range of extruded products. The first part of Extrusion Cooking looks at general influences on quality. There are chapters on the selection of raw materials, criteria for selecting the right extruder, analysing and optimising thermal performance in extrusion cooking, and effective process control. There is also an important chapter on maintaining nutritional quality in extruded products. The second part of the book looks at the application of extrusion in particular product groups. Each chapter examines the range of extruded products within the product group, the specific production issues and future trends. It also includes chapters on key products such as breakfast cereals, snack foods and baby foods. Extrusion cooking will be widely welcomed as a major reference in maximising the quality of extruded products. A key reference to improving efficeincy and quality on extruded products
