All versions of the sterilizer, the total effective cross-sectional area of the channels 7 is equal to the effective cross-sectional area of the inlet 2 of the housing 1, and a relatively movable surfaces of the channels 7 are made of heteropolar of electrets. In all variants, shown in Fig. 1, 2, 7-13, sources 6 ultrasound are sources of axial oscillations, while in Fig. 9-13 antiphase and in the variants shown in Fig. 3-6, the sources 6 ultrasound are sources radiantheat into the inlet 2 of the housing 1. Passing through the dividers 11 or 18, if they are necessary, the product is evenly distributed through the channels 7 between the relatively movable elements of the sterilizer. The formation of stagnant zones and local overheating of the product is excluded by the breakers 11 or 18, performing the pointed edges on the disks 5 and the rings 17, performing a total effective cross-sectional area of the channels 7 is equal to the effective area of the inlet 2 of the housing 1 and install petals 9 disc 5 with the formation of the flow channel relative to the surface of the dividers 11 in each end position with an effective cross-sectional area equal to half of the effective cross-sectional area of the inlet 2 of the housing 1, depending on the device run.

Dissipative heating of the product and its electrification occur uniformly throughout the volume due to the absence of dead zones, coaxial location of the hole is Oh by the formula (1) or (2), which provides a uniform deformation of the product in the channels 7, and ensuring coagulation and separation of the gas phase in the field of ultrasonic vibrations and inertial forces, eliminating the discontinuity of a deformable film product. In addition, ultrasound has a sterilizing effect, but a combination of thermal, electrostatic and ultrasonic treatment is synergistic with the destruction of the microorganisms. Obtaining contamination of the processed product at the outlet of the device is not more than the specified or the sterility of the product is determined by the moving speed of the movable elements and the power of ultrasonic vibrations. Processed pasteurized or sterilized product is removed from the housing 1 through the outlet 3. It is established by the vibrations of contamination of the processed product in time, regardless of its initial gas saturation or getvideoentry ability.
