This course deals with the various engineering properties of AB materials such as physical, electrical, mechanical, rheological, thermal and optical. Background on these properties is necessary in the design, management and operation of agricultural equipment employed in the pre and postharvest processes. The basic knowledge on these properties are of great importance for agricultural and biosystems engineers towards efficient process and equipment development. Among the main goals of this course are to identify engineering properties of agricultural and food materials, explain related measurement methods, and relate engineering properties of agricultural and food materials to process design and quality control.
