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.

Drying grain is necessary for proper storage, handling and processing; the methods used for drying grain have an important influence on quality and the overall economics of the process. This book provides all the tools needed for effective grain drying, inculding mathematical theory, tabulated data on the physical and thermal properties of grains, and more.

Deals with the main aspects of preservation of grains after harvest in tropical and subtropical regions. Presents the entire range of technologies currently available, from the farm granary to large-scale storage facilities. Special emphasis has been placed on quality control as it is becoming more and more important in view of the marketable surplus. Aimed at private and public sector storage operators, extension workers, students and researchers.

This work takes a multidisciplinary approach to grain storage research, applying knowledge from the fields of biology, cereal chemistry, economics, engineering, mathematical modelling and toxicology to the study of the complex interactions among physical and biological variables in stored-grain bulks that cause the deterioration of stored grain. Details the prevention and control of pests and contaminants.

The Organic Grain Grower is an invaluable resource for both home-scale and commercial producers interested in expanding their resiliency and drop diversity through growing their own grains. Longtime farmer and organic pioneer Jack Lazor covers how to grow and store wheat, barley, oats, corn, dry beans, soybeans, oilseeds, grasses, nutrient-dense forages, and lesser-known cereals. In addition, Lazor argues the importance of integrating grains on the organic farm (not to mention within the local food system) for reasons of biodiversity and whole-farm management. The Organic Grain Grower provides information on wide-ranging topics, from nutrient density and building soil fertility to machinery and grinding grains for livestock rations.--COVER.
