Operations of cavitation reactors are based on activation of ultrasonic cavitation in the thin layer, processed liquid pumped over through the reactor as a result is formed stable dispersion of mixed components.
On an entry of reactors, liquid is supplying and it has the greatest volume in a received emulsion. Through the second entry is supplying liquid component. Both entry fittings are located below oscillator to provide supply of two initial working liquids in a cavitational zone which is located below a face surface of a oscillator. After l processing of two and more a mixes in cavitation reactors there is ready emulsion. Such design can be applied and to intensive discrete processing of working liquid.
Cavitation reactors are used for implementation of the following technological processes: dispergating, homogenization, preparation of resistant emulsions, effective mixing and disintegration.
Dispergating is a thin crushing of hard components in liquid as a result of which disperse systems are formed: powders and suspensions.
Homogenization is process of reduction of mixes heterogeneity in the liquid environment by crushing and their uniform redistribution on volume. Homogenization process in essence represents operation of crushing and dispergation of particles for receiving completely uniform structure of substance. For example using homogenization process, fat in milk can be broken so carefully that particles repeatedly aren’t recombined, and cream isn’t formed.
The emulsion is dispersion of microscopic particles of one liquid in another. Emulsions can be formed by any immiscible liquids. In most cases one of phases of emulsions is water. Resistance to stratification of emulsions received in the ultrasonic reactors equals to several months.
Mixing – receiving substance uniform in structure at simultaneous processing in the ultrasonic reactor of two or more different substances. It is applied at dissolution of hard substances in liquid and at liquid dissolution in liquid. Reactor accelerates the process of dissolution by 3-5 times, when processing slightly soluble substances process of dissolution is accelerated by 10-30 times, and when mixing soluble substances process of dissolution is accelerated by two orders.
Disintegration is a division of substance into components or disintegration of difficult particles to fragments.
Cavitation is the main process which is influencing to dispergating. It allows to receive materials extra small dispersion and is widely used both in laboratories, and for receiving steady suspensions and emulsions in a number of technological processes such as chemical, food, pharmacological, textile, paint and varnish industry, petrochemical and etc. It is possible to receive rather steady emulsions, for example water-kerosene, water-oil, water-gasoline, water-glycerin, etc. substances which among themselves don’t mix up without ultrasonic influence.
Cavitation reactors are the base for blending systems manufactured by GlobeCore blending company. The main purpose of our systems is the intensification of dispergating, homogenization and emulsification of various components which would be mixed up by regular hashing. Liquids and suspensions form the steady fine mix, the received product has resistance to a long uniform period of storage and is steady against stratification. The company makes hydrodynamic blending systems: compounders, cavitators, blenders, dispergators, homogenizers and mixers of other types.
