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.
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.
Drying grain, especially corn, with conventional artificial drying methods requires great quantities of petroleum fuel during a short harvest period. Two systems of drying are used: high-speed, high temperature batch or continuous-flow and low temperature in-storage drying. Solar energy was studied as an alternative or supplemental source of energy for low-temperature drying at several different Midwest locations.

Drying is fundamental step in the maufacture of many foods. Although its primary function is to remove appropriate quantities of moisture it is, in many cases, also responsible for imparting the characteristic qualities that distinguish one product from another. This book provides a fundamental understanding of moisture transport in the drying of foods and of the physical and chemical changes that occur during drying. A comprehensive description and assessment of the different types of dryers available to the industry are given and factors effecting the operation, control and selection of dryers are described. The combination of practical information supported by relevant theory makes this an essential volume for industrial food engineers, those involved in equipment manufacture, process plant design and new product development in all food sectors where dried foods are used. It will also be of interest to academic researchers in this aspect of food engineering.
