The book is devoted to the issues of technology and technology of the process of drying drugs, which is determined by a complex of interrelated phenomena of a physicochemical, biological, hydrodynamic and thermophysical nature. Analysis and classification of drugs of chemical-pharmaceutical industry as objects of drying, numerical values of structural-mechanical, heat-and-business characteristics, forms of moisture and materials connection and methods of determination of these values are given. The state of the equipment design of the drying process of medicinal products, schemes and performance indicators of periodic dryers, as well as promising directions for the development of drying equipment (spray dryers, installations with active hydrodynamic modes, sublimation, etc.) for the purpose of their use in the chemical and pharmaceutical industry are considered. General principles of dryer design for chemical-pharmaceutical industry products, selection of optimal type of dryer and optimal operating parameters, issues of automation, occupational safety and health are considered.
