This article examines the design of rotary-pulsating units intended for intensifi cation of homogenization, dispersion, extraction, and absorption processes. The intensifi cation and effectiveness of the processes is provided by interaction between forces of a different nature, which develop as a result of complex-fl ow hydrodynamics, acoustic vibrations, and cavitation. Experimental investigations were conducted to determine optimal production and design parameters for implementation of these processes.Rotary-pulsating units (RPU) are universal designs for implementation of absorption, homogenization, dispersion, extraction, and other processes. Intensification is provided by a combination of processes and organization of directional recirculation of flows. Moreover, acoustic vibrations (20-2·10 4 Hz), and under certain conditions − such phenomena as cavitation and pulsating micro-flows that contribute to an increase in the rate of physicochemical processes in heterogeneous systems − develop in the medium being treated. As a result of multiyear studies under our guidance and direct participation, a group of rotary-pulsating units intended for intensification of processes of different purposes has been developed and investigated at the Kemerovo Engineering Institute of the Foodstuff Industry. The basic design of the RPU [1] is shown in Fig. 1.Two distributing baffles, one of which is mounted at the base of the rotor, and the other situated in the median section of the housing, are established on a shaft in the housing of the unit. A slotted stator is rigidly affixed to the cover. The jacket is intended for cooling of the medium being treated, and stabilization of the temperature regime. The function of the baffles is to distribute material flows within certain operating domains of the unit, contributing to rigorous circulation of the mixture within the volume of the unit.Design characteristics of the RPU dictate a complex path of displacement of the medium being treated within the unit. The initial components are delivered through the intake pipe to the central part of the unit. The flow is directed into the inter-cylinder gap by the centrifugal force that develops as the rotor turns; in this gap, the flow is subjected to the complex effect of forces of a different nature. Periodic covering of the slots of the rotor and stator contributes to generation of acoustic vibrations, and development of micro-flows with varying directions of motion. Moreover, the product is subject mechanical effects due to the impact of particles against the edges of the slots in the rotor and stator, the distributive baffles, and the internal surface of the unit. The complex flow hydrodynamics is supplemented by development of shear stresses, a hydraulic
