As agriculture becomes increasingly mechanised, it becomes pertinent to consider not just the proper application of the best engineering technology to agriculture, but also its relevance, and agricultural process engineering provides a step in the right direction. The current text aims to delineate for the readers about what entails agricultural process engineering. Discussing its principles, concepts and practices, the book seeks to acquaint the reader with the primary concerns of this field which includes such practices as designing agricultural machinery, power system design, environmental science, food and bioprocessing technology soil and water conservation, etc. The aim of the text is to not just list and discuss these endeavours, but to infact make assessment of the opportunities, challenges and prospects offered by it. In addition, it vies coverage to current trends and developments in the field, lending its contents a more relevant outlook.
