Drying And Storage Of Cereal Grains

Finite Element Analysis and Computational Fluid Dynamics have been introduced in modelling and simulation of drying and storage systems, these techniques are expected to dominate the future research and development of drying and storages, and should reduce losses and improve the quality of agricultural products, enhancing food security globally. Drying and Storage of Cereal Grains, Second Edition, covers the wide spectrum of drying and storage methods applied to economically important cereal produce, providingnumerical examples for better understanding the complexity in drying and storage systems through modelling and simulation, aiding design and management of drying and storage systems. Chapters 1 to 8 look at air and grain moisture equilibria, psychrometry, physical and thermal properties of cereal grains, principles of air flow, and provide detailed analyses of grain drying.Chapters 9 to 13 focus on temperature and moisture in grain storages, and provide comprehensive treatment of modern grain storage systems. The book also includes a number of unsolved problems at the end of each chapter for further practice. This revised second edition includes new sections on - heat of sorption finite element modeling of single kernel CFD modeling of fluidized bed drying exergy analysis and neural network modeling numerical solution of two dimensional temperature and moisture changes in stored grain This book will provide students in agricultural engineering and food engineering with a wide spectrum of drying and storage studies previously unavailable in a single monograph. It will also serve as an excellent reference for practicing agricultural engineers, food engineers and food technologists.

This text and reference discusses the drying of grains, in particular the staple cereals, maize, rice, and wheat, and the oilseeds, soybeans and canola. The basic physical and thermodynamic properties of grain and air are examined, and the theory of the drying process is developed. Design of the optimum operating conditions for on-farm and off-farm dryers are presented. The book is written as an engineering text, but should also prove beneficial to all who are interested in the proper drying and storage of grains. Examples and problems are given in both S.I. and Imperial units.

Drying and storage are two significant unit operations in the food industry and are applied to both raw and processed products including cereal grains, oilseeds, legumes, flour, noodle, coffee, and cornstarch. The common characteristic of these materials is that all of them are hygroscopic and contain water. The hygroscopic properties are influenced by their physical properties, which are influenced by their storage environments such as bins, warehouses, bunkers, and temporary storage structures. This book focuses on the storage and drying of bulk products in these storage structures. On many occasions in our work with the grain storage and drying personnel especially our graduate students and industry contacts, we found a book explaining the fundamental principles of grain storage and drying is needed. Therefore, the primary objective of this book is to help readers understand the fundamental principles of grain storage and drying and develop a well-informed approach to solve grain storage and drying problems. Technologies for grain storage and drying are advanced through research; therefore, literature review and background on each topic has also been included. The book is generally intended for grain storage and drying students, engineers, and scientists. As reflected in the contents which are presented at several levels of depth, this book will serve well readers with different backgrounds and interests. An effort has been made to allow for independent reading of different sections, and to make a large part of this work accessible to a non-mathematical audience. The authors have combined their experience of teaching grain storage and drying to undergraduate and graduate students in the faculties of Agricultural and Food Sciences and Engineering. Material in the book is organized into broad topic areas: physical properties (Chapters 1 and 2), grain temperature and moisture (Chapters 2 and 6), water in biomaterials and relationship with its environment (Chapter 3), fundamental principles of aeration, drying, and rewetting (Chapter 4), and mathematical modelling of isotherm, drying, and re-wetting (Chapter 5). We hope our readers will benefit from the contents of the book for many decades.

Principles of grain drying; Moist air properties; Grain quality deterioration; Grain equilibrium moisture content; Air movement; Introductory analysis of fixed bed drying systems; Grain drying system; Controls for dryer operation and safety.

Storage of Grains and Their Products, Fifth Edition, presents the most authoritative reference on the principles and practices of storing and handling grains and their products. Divided into four main sections, the book covers the range of storage systems available in both the developed and developing world, the practicalities of the design and implementation of grain storage systems, looking in detail at handling, cleaning, drying, aeration, instrumentation amongst other topics, specific threats to stored grains, pulses, oils and pseudocereals from chemicals, rodents, insects and biosecurity, and the economics of grain storage, government regulations and future considerations. Professionals responsible for the storage and handling of grains will find this book a great resource, however, it will also be of interest to academic researchers and postgraduate students in both cereal science and food processing. Presents an up-to-date, end-to-end overview of the processing and storage of grain and grain related products Includes eleven new chapters that provide the latest insights into grain storage Edited by active cereals researchers working in industry, with experts from both academia and industry supplying chapters Includes essential information on the design and operation of grain facilities Provides coverage of the preservation of grain quality against specific threats

This unique book is written specifically for those in grain operations and addresses the full range of topics related to maintaining the quality of grain stored on the commercial scale. It demonstrates how science-based information can be incorporated into grain storage operations to increase efficiency and decrease the risk of grain deterioration. Written in layman?s language, it will be comprehensible to every reader regardless of academic background. The focus of the book reflects the author?s many years of research experience in farm bins and grain elevators, in addition to his extensive contact with grain operations? professionals, both on the job and in the more than one hundred storage meetings he has conducted. The text was reviewed by grain industry leaders to ensure that it speaks to the information needs of real grain handlers and by leading scientists to ensure the accuracy of the information.This book will not duplicate any book on your shelf -- it does not merely summarize the information already available to grain operations personnel. Rather, the text guides the reader to the existing publications before proceeding to information not available elsewhere. Topics covered include: grain quality factors and terminology; grain insects and molds; physical processes affecting stored grain; grain sampling and monitoring; sanitation in grain elevators; aeration management; grain dryer management; and bulk grain fumigation. This resource will be of use to grain handlers, grain storage managers, grain elevator managers, bulk handlers, and grain merchandisers. It will also be an excellent teaching tool for courses in Agricultural Systems Management, Transport and Distribution - Grain Handling, Grain Processing, Feed Manufacturing, Grain Drying & Storage Systems, Grain Storage, Flour Milling, Applied Entomology, Applied mycology, and related areas of study.
