The description of the reactor with symmetric oscillatory system of the acoustic cell, designed with application of mathematical model of multibubble cavitations and theories of similarity of acoustic cavitational processes is displayed. The example of the project of the reactor which will be made for republic Belarus is displayed. Is described its comparison with the known from technical and patent literature analogs of acoustic cavitational reactors suitable for application in food sonochemistry. The reactor is intended for physical and chemical processing the ultrasonic cavitations of true and colloidal solutions, and also disperse systems (emulsions and suspensions) by initiation in them sonochemical reactions and cavitational erosion of their phases. In addition to these solutions, emulsions and suspensions in these reactors can be processed chemically pure water and other chemically pure solvents. In them is the impact on their physical-chemical state of liquids, the intensification of in them chemical reactions and initiation of new by changing the dipole-dipole and ion-dipole interactions in their environments and phases, as well as increasing the dispersion of multiphase systems, the destruction of bacteria and stabilization of their number. It is shown that the proposed requirements to the size of the solid parts of oscillatory system acoustic cell cavitations power and performance of the reactor is increases, the cavitation erosion surfaces of its parts and useless loss of energy elastic wave is decreases.

In comparison with well-known, describes in the technical and patent literature counterparts acoustic cavitation reactors suitable for use in food sonochemistry, consider examples of the executed on the basis set forth in the  of theoretical bases of projects reactors, mastering the production of which started in Estonia and prepared in the republic of Belarus. They are intended for physic-chemical treatment by ultrasonic cavitation true and colloidal solutions, as well as disperse systems (emulsions and suspensions) by initiating in them the sonochemical reactions and cavitation erosion of their phases. In addition to these solutions, emulsions and suspensions in these reactors can be processed chemically pure water and other chemically pure solvents. In them is the impact on their physical- chemical state of liquids, the intensification of in them chemical reactions and initiation of new by changing the dipole-dipole and ion-dipole interactions in their environments and phases, as well as increasing the dispersion of multiphase systems, the destruction of bacteria and stabilization of their number. However, such reactors, though meet all requirements of developed in Russia the conception of a food sonochemistry , possess low productivity and have an appreciable cavitational erosion of surfaces of details of a design and loss of energy of an elastic wave.
2. REVIEW OF TECHNICAL AND PATENT LITERATURE
A typical example of a well-known classical design of the reactor is, for example, a device, patented in the united states for nearly half a century ago, and is called the "vibrations device" . It is equipped the reflecting wall, mounted so that his surfase is aimed in the liquid, is in one plane with the surface of ultrasound radiator, surrounding it. That is, surface of the front of ultrasonic wave, containing surface of the radiator, coincides with surface of the wall, which has contact with liquid. The second of reflective wall, located opposite first and radiator in the direction of propagation wave is part of the corps of reactor. But the energy of cavitation is the cause of erosion fracture of solids . Erosion may be subjected the structural elements design of cavitation reactor. The products of erosion, falling in the treated liquids, can irreversibly change its physical and chemical properties, which are strictly not allowed in the processing of medicinal and food raw materials, as well as the medical products and food products. Housing this device is exposed to cavitation erosion, caused by his contact with the perimeter of the cavitation areas, which related to it work . In addition, because the reflective the wall which is lying opposite the radiator is part of the hard corps, it not may fully reflect the elastic wave and its fluctuations partially transmitted the on the corps, which leads to energy losses. The surface of the radiator and the walls are exposed to erosion under the action of
|SUPERCRITICAL CO2 EXTRACTOR FOR SALE: 5L, 10L and 20L - 2,000 psi Complete Supercritical Fluid Extraction System - closed loop. Our systems are made at our fabrication shop in the state of Washington. Systems available: 5L, 10L, 20L, 100L, and larger custom. Typical build time is 2 weeks. This is not a Apeks Supercritical or Waters Supercritical CO2 Fluid Extraction System. We believe it is a better system, since we use 1/2 inch tubing for the CO2 flow, which is 4 times the flow rate of a Apeks, and up to 64 times the flow rate of a Waters system. We believe the result is faster processing time and better yield from increased exposure to CO2 solvent. Perfect for extraction of terpenes, trichomes, and Cannabinoids. Supercritical CO2 Fluid Extraction is a art, and the operator must have experience and training to obtain results. Go to website|
