The sterilization (disinfection) of biomedical objects and raw food materials is one of the topical areas of microwave radiation application. The most sterilizers known in Russia and the world use the principles of thermal action and require a long processing time (at least an hour). These installations are stationary, with large dimensions and weight. Therefore, the possibility of employing electromagnetic radiation in sterilizing processes distinguished by ease of control, inertia-free, selectivity, energy and economic efficiency is of particular interest. Mentioned properties open up the possibility of designing ultra-fast compact sterilizers with small weight, adapted for manual transportation. Such sterilizers are able to provide prompt medical care not only in the daily practice of clinics, but also in field hospitals, in zones of military conflicts and in emergency situations. The objective of the present study is the experimental and theoretical substantiation the possibility of realization an ultra-fast (operating time: several minutes) microwave sterilizer with the simple application technology and pilot set-up of low-intensive pulse action for treatment of biological materials. The experimental installations allowing exposing the objects under study with microwave radiation both in continuous generation and in pulsed regimes have been developed. The parameters of containers for placing objects of sterilization have been selected. Modes of complete sterilization of the studied objects are established. Mathematical models for calculation the elements of the waveguiding feeders, the operating chamber, and the magnetron oscillator are built. The possibility of developing a magnetron with a power of 1,5 kW in continuous mode allowing increasing the number of sterilized objects and reducing the processing time is shown using numerical model.
