: -The article presents a new development of the Moscow State University of Technology and Management -sonochemical reactor for water processing. A mission of sonochemistry is described and her factors that can effectively apply her to the food industry, disclosed. The results of studies of the food sonochemistry described, mainly for technology of dairy industry. Considered the problems of sonochemical reactors, which prevent the use technology of nonparametric amplification of cavitation in the food industry. The project of reactors of the cylindrical wave and nonparametric amplification of cavitation, which can be effectively used for the industrial preparation of the mixtures from dry dairy components proposed and was compared with the known reactors.
