Small-Scale Milling A Guide for Development Workers

About this book

Small-scale Milling is a comprehensive and practical guide to improved food processing in both rural and poor urban areas, bringing together the authors' many years of practical experience in this field. It has been written because of a lack of practical guidelines for designing and managing viable milling programmes. This book is essential reading for anyone involved in milling in developing countries, and the target reader is the extension worker promoting improved small-scale milling techniques. The book can be used as both a manual and as course material for training at all levels.
