Thermal Properties

This textbook on the thermal properties of food and agricultural material has chapters which deal with the following subjects; basic concepts of heat transfer, as related to thermal processing and techniques for determination of available data on specific heat of raw and processed food and feed products, soil and wood a number of illustrated examples are included to demonstrate the use of a given technique or principle ; methods for determinaion of data on thermal conductivity, thermal diffusivity, unit surface conductance or the heat transfer coefficient of foods and agricultural materials; and, the applications of thermal properties in relation to cooling, freezing, drying, heat treatment, heat of respiration, and thermal expansion.
