The first source book in the field, this book gives an overview the fundamental principles of electrical techniques, electrophysical properties of foods and agricultural products, application of various emerging electrotechnologies for enhancing the solid-liquid separation and drying processes, extraction techniques of pigments, processing methods of different in-plant tissues and biosolids, electro-osmotic dewatering and electrofiltration of biomaterials, recent industrial- scale gains, and other aspects. Each chapter is complementary to other chapters and addresses the latest efforts in the field.
This book has several purposes: (1) to serve as a source of information about a representative collection of food processes with which Clark has had experience; (2) to convey some practical lessons about process development and plant design; and (3) to serve educators as a resource for class problems and discussion.
The book is organized in three broad sections. The first concerns processes that are primarily physical, such as mixing. The second concerns processes that also involve biochemical changes, such as thermal sterilization. The third section addresses some broader issues that have not been discussed elsewhere, including how to tour a plant, how to choose among building a new plant, expanding or renovating; and how to develop processes.
The book begins with an overview of solvent extraction technology. It examines pulsed electric fields and their effect on food engineering, and the potential and limitations of microwave-assisted extraction. It explores diffusion processes and reviews what is known about electrical discharge processes in the extraction of biocompounds.
Next, the book summarizes current knowledge on conventional and innovative techniques for the intensification of extractions from food and natural products, focusing on environmental impacts. It reviews recent developments in supercritical CO2 extraction of food and food products, describes the pressurized hot water extraction (PHWE) process, and examines future trends for PHWE. The book also examines essential oil extraction, and the tools and techniques of high pressure-assisted extraction. The authors demonstrate its application using litchi and longan fruits as examples.
The final chapters focus on extrusion-assisted extraction, gas-assisted mechanical expression, mechanochemically assisted extraction, reverse micellar extraction, and aqueous two-phase extraction. The book concludes with a chapter on the treatment of soybeans through enzyme-assisted aqueous processing, examining the economics involved as well as the development of the process.
A solid review of modern approaches that enhance extraction processes, this volume is destined to pave the way for future research and development in the field.
Gas-Liquid And Liquid-Liquid Separators is divided into six parts: Part one and two covers fundamentals such as: physical properties, phase behaviour and calculations. Part three through five is dedicated to topics such as: separator construction, factors affecting separation, vessel operation, and separator operation considerations. Part six is devoted to the ASME codes governing wall thickness determination of vessel weight fabrication, inspection, alteration and repair of separators500 illustrationsEasy to understand calculations methodsGuide for protecting downstream equipmentHelps reduce the loss of expensive intermediate endsHelps increase product purity
