Although heat pump technology has been around for several decades, its advantages and limitations are largely unknown. This volume covers drying fundamentals, theory, and experiments - linking these essential elements to heat pump dryer (HPD) design and industrial practices. Integrating various fields, it describes experiments, governing laws, and analyzed results from examples and solved problems. It presents recent research and dimensioning of HPD based on operating conditions required for enhanced product quality, low energy use, and low environmental impact. It also presents new approaches, such as environmentally friendly working fluids, intermittent drying, and cold extrusion.
