Technologies for processing (manure processing) manure depend on the system and method of keeping animals. This is due to the physical properties of the obtained manure, primarily its moisture content. By using litter, solid (litter) manure is obtained, which has a moisture content of 60...80%. If litter is not used when keeping pigs, then manure without litter is obtained, which is divided into two groups by moisture content: solid (60-80%) and liquid (82-98%). Vortex layer devices are equipped with different types of working bodies and layout of the working area. When carrying out liquid-phase processes, using ferromagnetic elements as a working body, trap screens or labyrinths designed to keep ferromagnetic particles in the working area can be installed on the ends of the non-magnetic insert (or only at the outlet). Grinding and mixing can occur not only with the help of ferromagnetic particles, but also with the help of knives, tubes or a rotor. In these cases, the sieves act as filters (separators). Ferromagnetic elements are added to the working area using an electromagnetic dispenser. Analyzing the results of previous scientific studies, it can be stated that increasing the efficiency of the vortex layer devices is proposed due to the improvement of the design or the substantiation of the structural and technological parameters of individual systems, without taking into account their interconnection. It should be noted that most of the obtained results from the substantiation of structural and technological parameters are experimental and do not have a theoretical justification. In order to solve the problems, the structural and technological scheme of the vortex layer apparatus for liquid manure processing, which allows to obtain liquid organic fertilizers of high quality with increased productivity and level of automation, is substantiated.

The main requirements for manure transportation and treatment systems are the following: ensuring the isolation of manure flows from air, soil, water; ensuring the maximum possible disinfection; ensuring the conversion of chemical elements into a form suitable for consumption by plants. The aim of the research is to analyze the technical and technological equipment of liquid manure processing processes using the process activation unit (UAP) using vortex layer devices (VHF) of ferromagnetic elements. As a result of the analysis of liquid manure processing technology of pigs it is established that the most effective technology in the conditions of Ukrainian farms is liquid manure processing by means of process activation unit (UAP) using vortex layer devices (VHF) of ferromagnetic elements. The essence of the proposed technology is that the manure together with the appropriate reagent in the working area of UAP is activated, which significantly accelerates the chemical reactions associated with the hydrolysis of fatty substances contained in effluents (alkaline environment). At the same time suspended substances in the manure are mechanically treated with ferromagnetic elements. Disinfected liquid manure at the exit of UAP has no specific odor, can accumulate in open manure storages (lagoons) directly on the farm. As a result of the analysis of the principle of work of installation of activation of processes features of its use are established: reception of multicomponent suspensions and emulsions; acceleration of the processes of obtaining fine mixtures, activation of substances both in the dry state and in the form of aqueous dispersions; for purification of industrial wastewater from phenol, formaldehyde, heavy metals, arsenic, cyanide compounds, acceleration of heat treatment processes, obtaining protein substances from yeast cells; increasing the microbiological stability of food and yeast activation in the bakery industry; intensification of extraction processes, including during the preparation of broths, production of berry drinks (juices), pectin, etc .; to obtain suspensions and emulsions of increased microbiological safety in the food industry without the use of stabilizers, as well as increase the yield of finished products.
