This book covers the technology of vegetable oil extraction, including theory, process technologies used for various oilseeds, machinery operation and design aspects. Pertinent topics are covered in two parts: mechanical expression and solvent extraction. The importance of each preparation operation is explained as related to oilseed structure, outlining the differences in the quality of prepared material from various oilseeds. It also covers modern press designs, designs of extractors, desolventisers and distillation line, and support equipment. Effect of each unit operation on final product quality, levels of safety and precautions in plant operation, and plant automation, are discussed. Finally, the book takes a peek at possible novel and green technologies to find solutions to problems faced by the industry.
Features:
- Provides comprehensive coverage of vegetable oil extraction technology as applicable to major and minor oil-bearing materials.
- Explains the effects of each of the seed preparation steps on cell structure, and how it improves oil extraction.
- Describes mechanical expression technology in detail, including the design aspects of presses and seed preparation equipment.
- Explores the design of solvent extraction process equipment, including extractor, desolventiser, distillation and support.
- Discusses extraction plant safety, plant automation and utilities.
This book is aimed at professionals, students and researchers in chemical and food engineering.
