Explore the Social, Technological, and Economic Impact of Heat Pump Drying Heat pump drying is a green technology that aligns with current energy, quality, and environmental concerns, and when compared to conventional drying, delivers similar quality at a lower cost. Heat Pump Dryers: Theory, Design and Industrial Applications details the progression of heat pump drying—from pioneering research and demonstration work to an applied technology—and establishes principles and theories that can aid in the successful design and application of heat pump dryers. Based on the author's personal experience, this book compares heat pump dryers and conventional dryers in terms of performance, quality, removal rate, energy utilization, and the environmental effect of both drying processes. It includes detailed descriptions and layouts of heat pump dryers, outlines the principles of operation, and explains the equations, diagrams, and procedures used to form the basis for heat pump dryer dimensioning and design. The author also proposes the use of heat pump dryers that operate on natural fluids and considers their potential for providing ecological benefits and easing environmental issues relative to conventional drying. The use of natural fluids in heat pump dryers is consistent with the Kyoto and Montreal Protocols. Highlights includes coverage of: Single-stage and multi-stage vapor compression heat pumps for drying A dryer design utilizing single-stage vapor compression heat pumps Design of a two-stage vapor compression heat pump for drying green peas and aromatic leaves Psychrometry of humid air and includes the various types of humidification processes Thermodynamic properties of refrigerants for heat pumps Heat Pump Dryers: Theory, Design and Industrial Applications discusses the ready-to-use technology of heat pump drying. The book compares conventional and heat pump drying, addresses the confines and limitations of conventional drying, and proposes viable solutions using this novel process.

Drying of solids is one of the most common, complex, and energy-intensive industrial processes. Conventional dryers offer limited opportunities to increase energy efficiency. Heat pump dryers are more energy and cost effective, as they can recycle drying thermal energy and reduce CO2, particulate, and VOC emissions due to drying. This book provides an introduction to the technology and current best practices and aims to increase the successful industrial implementation of heat pump- assisted dryers. It enables the reader to engage confidently with the technology and provides a wealth of information on theories, current practices, and future directions of the technology. It emphasizes several new design concepts and operating and control strategies, which can be applied to improve the economic and environmental efficiency of the drying process. It answers questions about risks, advantages vs. disadvantages, and impediments and offers solutions to current problems. Discusses heat pump technology in general and its present and future challenges. Describes interesting and promising innovations in drying food, agricultural, and wood products with various heat pump technologies. Treats several technical aspects, from modeling and simulation of drying processes to industrial applications. Emphasizes new design concepts and operating and control strategies to improve the efficiency of the drying process.

Drying is fundamental step in the maufacture of many foods. Although its primary function is to remove appropriate quantities of moisture it is, in many cases, also responsible for imparting the characteristic qualities that distinguish one product from another. This book provides a fundamental understanding of moisture transport in the drying of foods and of the physical and chemical changes that occur during drying. A comprehensive description and assessment of the different types of dryers available to the industry are given and factors effecting the operation, control and selection of dryers are described. The combination of practical information supported by relevant theory makes this an essential volume for industrial food engineers, those involved in equipment manufacture, process plant design and new product development in all food sectors where dried foods are used. It will also be of interest to academic researchers in this aspect of food engineering.
