BUILDING CHARACTERS THROUGH 3P IMPLEMNTATION (APPEARANCE-SERVICE-ACHIEVEMENT)
Authors: M. Iqbal
Published: January 2021

Character education in a micro context, centered on a holistic education unit. Education unit is the main sector that optimally utilizes and empowers all existing learning environments to initiate, improve, strengthen, and continuously enhance the character education process in educational units. Education is what will make serious efforts and always be at the forefront of efforts to form the true character of Indonesian people. Character development is divided into four pillars, namely teaching and learning activities in class, daily activities in the form of cultural development of educational units; co-curricular and / or extra-curricular activities, as well as daily activities at home and in the community. In order to realize the goals of education in schools, effective management is required, with the aim of ensuring: 1) community access to adequate education services; 2) the quality and competitiveness of education and its relevance to the needs of society; and 3) effectiveness, efficiency and accountability of education management. Appearance, service, & achievement (3P) are not new things in schools, but in fact there are still schools that do not pay attention to 3Ps properly. For example, there is still a school identity in the form of a school name board which is in a dull and rotten condition so that it cannot be read clearly & cannot provide accurate information about the school. Another example, there are still schools that ignore cleanliness, safety, comfort & beauty of the school environment such as yards, rooms (buildings) & others. Likewise, the school's lack of attention to neatness, cleanliness & harmony in the appearance and behavior shown by its residents. According to Simon Philips, character is a collection of values ​​that lead to a system, which underlies the thoughts, attitudes and behaviors that are displayed. Meanwhile, Doni Koesoema understands that character is the same as personality. Personality is considered as a characteristic, or characteristic, or style, or characteristic characteristic of a person that comes from formations received from the environment. In this sense the root of all evil and evil acts, evil acts, lies in the loss of character. Strong character is a fundamental view which gives the human population the ability to live together in peace and form a world filled with good and virtue, free from violence and immoral acts.

RESEARCH OF PUNCHING PROCESSES BY PACKING WITH USE OF SURFACE HEATING OF PREPARATIONS
Authors: Shtuts Andrii , Sluzalyuk Maxim
Published: January 2021

Despite the fact that stamping processes have been around for a relatively long time and have significant advantages compared to traditional approaches, as well as high technical and economic indicators, this process is not widespread.
The machine-building industry needs mass production and use of sophisticated parts of various designs. The need of Ukraine for the details of such a design varies significantly and can reach tens of millions of pieces. The need for ring blanks of type flanges (gear) of the total amount is more than 50% [1].
According to foreign enterprises, when cutting, the material utilization ratio is 40-50%, and when using stamping, it is pumped through using surface heating of workpieces - 75-80% [5]. If we take into account the use of energy for the production of steel and its processing per unit weight of the finished part, then it is 70–84 MJ / kg when machined, and 41–49 MJ / kg for plastic deformation.
To improve the ductility and deformability of the material, it is advisable to use induction plants for heating carbon steel preforms before pressure treatment. Two types of fundamentally different heating options are used: pass-through, when the workpiece warms up to its entire thickness with a temperature difference between the surface and the core of 50-100 °, and surface, when you need to heat only a relatively small layer of metal to a certain depth.
Before stamping, wetting requires the use of surface induction heating, which provides greater surface plasticity of the workpiece material without changing its structure [3]. In this regard, surface and end-to-end inductive heating installations are widely used in stamping processes for wetting.
The absence of theoretically justified parameters of the regime leads to the use in practice of induction heating of systems with unsuccessful design solutions and relatively low technical and economic indicators.
Thus, there is a need for relevant research aimed at determining the rational parameters of the heating mode, providing on this basis effective processing of workpieces.

Published: January 2021

The research results of the mathematical model development of dynamic processes in a peristaltic concrete pump with a hydraulic drive are presented. Cast concrete occupies a leading place in modern construction. Peristaltic concrete pumps are good proved in this area. Developing of devices for performance of such activities is an actual task. One of contemporary efficient directions in its solving is an adequate modeling of dynamic processes in mentioned devices. The model is development in the form of a differential equation for rotation angle of the pump rotor; contains general geometric characteristics, rotor’s mass characteristics, dynamic characteristics of the hydraulic motor, parameters of the hose and a structural mix. A method has been developed for the resistance torque forming to rotation of the pump rotor from rollers deforming the hose. A model of the friction forces during the movement of the structural mix is proposed. An expression is obtained for the resistance forces as result of gravity forces action on the mix particles in the outlet part of the hose. An approach is proposed for using catalog data to represent the torque of a hydraulic motor as a function of the angular velocity of its rotor.
Researches of dynamic processes by using the proposed model are carried out. Important technological regularities of the unit functioning have been established, in particular: the mortar speed may have a significant variable component; the mortar speed and the pump performance increase with a decrease in the length of the outlet hose and a decrease in its height, a decrease in the rolling friction coefficients for the rollers, and not using of the side rollers.
The conducted research show that an increase of an altitude leads to a decrease in the average speed of the mixture and the frequency of pulsations. In this case the amplitude of velocity pulsations increases. With an increase in the length of a deferent hose, the amplitude of velocity pulsations changes insignificantly. The rejection of side rollers leads to an increase in the average speed of the mixture motion with minor pulsations. The walls of the hose, however, in this case experience more intense bending stresses, which reduce the product life of the hose.

Authors: Stepanenko Sergey , Kotov Borys
Published: January 2021

Development of a mathematical model and calculated analytical dependencies for determining the trajectories and parameters of grain movement in a vibro-fluidized layer of grain material components under the action of a pulsating air flow.
They are based on the methods of deterministic mathematical modeling and theoretical mechanics based on the equations of motion of a material point at a variable air flow speed and the action of a pulsating air flow. Theoretical studies were carried out using the methods of mathematical analysis and modeling. The research results were processed using elements of the theory of probability and mathematical statistics using software packages; to determine the rational parameters of the process, the method of statistical experiment planning was used.
A mathematical description of the motion of the grain material particles in a combined vibration-air separator under the action of a pulsating air flow of variable speed is given. The trajectories of motion of particles with different sizes are obtained.
The obtained equation of motion of a particle under the influence of a pulsating air flow makes it possible to determine the dependence of the speed of movement of the material in a vibro-fluidized layer of grain material on a number of factors: the geometric parameters of the sieve-free sieve, the feed angle of the material, the initial kinematic mode of the material, the index of the kinematic mode of the sieve-free sieve, as well as the coefficient of windage of the grain.
On the basis of theoretical studies, the possibility of separating particles of grain material into fractions according to aerodynamic properties with vibropneumatic loading of grain into the channel has been determined. The use of a pulsating air flow as a separating carrier, and taking into account the deflecting forces, made it possible to significantly increase the splitting of the trajectories and the criterion for dividing the grain into fractions.

Published: January 2021

The article deals with one of the ways to improve the energy situation in agriculture of Ukraine, namely to increase the energy efficiency of solar air heaters through the use of granite heat accumulators.
In the world, in recent years, the share of energy produced by non-traditional sources has been steadily increasing. Unfortunately, in Ukraine this proportion is much smaller than in the first world countries. This problem is especially relevant for agriculture. The main renewable energy sources for Ukraine's agricultural sector are biofuels (solid, liquid, gaseous), wind and solar. The latter is the most attractive for widespread use in agriculture. After all, for the production of biofuels requires at least land, mechanization and chemistry, etc., for the production of wind energy requires appropriate weather conditions that are not available in most regions of the country. And only solar energy is everywhere and almost always. The difficulty of using solar energy at night is one of the main constraints on the widespread use of solar installations. The use of heat accumulators (in devices that accumulate heat during the day and give it away at night for production purposes) for solar heaters greatly enhances their technological capabilities. Battery material is a variety of materials - from soil to plastic water bottles. This article discusses the theoretical justification (confirmed by experimental studies) of the choice of rational size and shape of granite heat accumulator elements.
To simplify the task, it was assumed that the battery element has a spherical shape and its thermophysical characteristics remain constant throughout the process of heating and cooling. As a result of the solution of the differential equation of thermal conductivity for these conditions, the dependence of the liquid temperature distribution depending on the radius and time of heating was obtained. The battery element is fully charged when the liquid temperature in the center and on the surface is equal. The temperature distribution in the middle of the liquid was also determined when cooled. Theoretical calculations were confirmed by experimental studies. To determine the rational parameters of the battery cells, a criterion was proposed, the value of which depends on the ratio of heating and cooling time, heating and cooling temperatures, the location of thermocouples.
As a result of theoretical and experimental studies, it is established that the rational size of the granite element of the heat accumulator is an equivalent diameter of 0.3 m. The use of a heat accumulator of this type allows to evaporate more than 300 kg of moisture, which allows to reduce the hay ventilation period, to reduce nutrient losses.
THE CONTACT INTERACTION DYNAMICS OF THE WORKING TOOL OF THE MOLE PLOWSHARE WITH THE SOIL DURING FORMING PROSESS A CHANNEL FOR AN ANTI-FILTRATION SCREEN

Published: January 2021

Today's realities of agriculture are increasingly prompting the need for the introduction of technologies for subsoil irrigation, as a possible tool to obtain maximum efficiency indicators of agricultural activities of agricultural enterprises. At the same time, the large-scale introduction of intra-soil irrigation technologies at the enterprises of the agro-industrial complex is significantly complicated due to the poor practical and theoretical development of its methods, as well as the lack of extensive experimental verification of this method of irrigation.
The development of many processes in the construction of irrigation and engineering structures requires substantiation of the geometric parameters and operating modes of the working bodies that are used to implement these processes. One of the working bodies that is used to form the cavity along which communication is stretched is a mole plow, which, depending on the expected working conditions, may have a different geometric configuration and size.
The results of investigations of the interaction of the mole ploughshare with the soil in cavity formation for laying the anti-filtration screen are describe in this article. The authors propose to consider the soil in the form of an elastic-viscous model. By solving the contact problem of the interaction of a rigid body with a deformed medium, the stress components in the soil on the contact surface with the ploughshare are determined, and soil compaction is determined. The components of forces that appear on the surface of the ploughshare because of its interaction with the soil are determined depending on its geometric parameters and the mechanical properties of the soil. This solution is a general approach for the analytical solution of the class of problems of the contact interaction of a rigid body with a deformable medium possessing the properties of elasticity and viscosity.
RESEARCH OF CONSTRUCTIVE-TECHNOLOGICAL PARAMETERS OF WORKING BODY FOR SCATTERING BULK MATERIALS

Published: January 2021

Machines used in world practice for surface application of mineral fertilizers are often equipped with centrifugal devices with vertical or horizontal location of the axis of rotation. Having high productivity and reliability of technological process, they cannot always provide reception of a necessary dose and uniformity of scattering of fertilizers on width.
In Ukraine, currently produced machines for the application of mineral fertilizers, which we have not previously produced. Since about 2/3 of all available mineral fertilizers, as well as most of the limestone and gypsum-containing materials are applied in a continuous manner, it is necessary to have a certain fleet of machines for applying fertilizers available to consumers. Fertilizer application in a continuous manner is carried out by land and aviation.
One of the main agrotechnical requirements for machines for the application of bulk materials (mineral fertilizers) is their uniform distribution on the field surface. From uneven application of fertilizers, the reduction in grain yield reaches 10 ... 15%.
The main disadvantages of the machine for applying mineral fertilizers are: imperfect design of the spreading mechanism, which leads to uneven scattering of fertilizers on the field surface; a large number of gears, which affects the metal content and cost of manufacture and complicates the design.
Chain transmissions that drive the spreading device and the conveyor (during operation the chain is stretched, which requires the use of tension rollers, and take-off from the sprockets, especially on the drive of the spreading device); significant uneven application of fertilizers due to imperfect design of the spreading disc.
The main reason for the low quality of fertilizer distribution by scattering machines, most researchers see a significant impact on the technological process of external random factors: field relief, wind speed and direction, humidity, elastic, frictional, hygroscopic and particle size distribution of fertilizers. Therefore, the improvement of the technological process of fertilizer scattering, in order to ensure a given uniformity of their distribution on the field surface in the conditions of real functioning, is an urgent scientific and practical task. In order to eliminate these shortcomings, a new spreading working body is proposed.

Published: January 2021

Today the vibrodiagnostic method achieves the highest efficiency and manufacturability for the operation of the technical condition of the technological equipment of the agro-industrial complex. At the same time, this method is one of the most modern methods of technical diagnostics, indicating the kinematic warehouses of diagnostic objects. Vibration analysis is a fundamental tool for diagnostic monitoring of bearings. The vibration signal of defective rolling bearings and its spectrum contain characteristic features by which it is possible to fairly correctly identify the type and location of the defect. At the moment the defective element passes through the loaded zone of the rolling bearing, a pronounced peak, an energy impulse, appears in the vibration. Thus, when a bearing with internal defects is operating, characteristic components appear in vibration - harmonics with natural frequencies, the numerical values of which can be calculated using theoretical formulas using the geometric dimensions of the bearing elements and the rotor speed of the mechanism. In a loaded bearing, four characteristic frequencies can be distinguished that are used for diagnostics - the frequency of the outer bearing cage, the frequency of the inner cage, the cage frequency and the rolling element frequencies. The complexity of the analysis of vibration signals of rolling bearings for the purpose of their diagnostics lies in the fact that the signs of a defective bearing are distributed over a wide range of frequencies, have low vibrational energy and are somewhat random in nature. In addition, the vibration signal is, of course, removed from the body of the equipment containing the bearing, and therefore contains not only information useful from the point of view of bearing diagnostics, but also noise - vibrations produced by other parts of the mechanism. The analysis of methods for diagnosing bearing defects based on wavelet analysis of their vibration signals allows us to single out the most promising direction, which consists in the fact that the bearing vibration signal is decomposed into coefficients using wavelet analysis, after which the most significant coefficients are selected from these coefficients.
ENSURING CONTINUOUS HYSTERESIS OF SPROAD ACTION VALVE SAFETY VALVES
Authors: Stadnik Mykola , Shargorodskiy Serhiy , Rutkevych Volodymyr
Published: January 2021

In the article principles of construction and design of spring valve units are considered, which allow to obtain a given dynamic quality to ensure constant hysteresis of spool safety valves of direct action. The analysis of efficiency of devices of correction of dynamic quality of spring valve units for ensuring their working capacity at variation of external operating factors by purposeful management of kinematic and force parameters of elastic-damping elements, and also the reasons influencing hysteresis
It is noted that one of the reasons for the increase in hysteresis is damage to the rubber seals of the spool safety valves of direct action. Identifying the main causes of damage to rubber seals: constant friction of the edge of the radial holes of the spool on the seal ring; reverse the direction of the operating pressure; the pressure drop created by the axial hole of the spool when the valve is fully open.
A spool spring valve with a mechanical spring having high throughput and low hysteresis is proposed. This characteristic was achieved through the use of high quality materials, which allowed to have a high throughput with minimal dimensions; optimization of geometrical characteristics of the flowing part of the valve; reducing the seal tension and, as a consequence, reducing the hysteresis.
It is noted that the absence of contact of the radial holes of the spool with the rubber seal in the extreme off position protects the seal from plastic deformation during reverse flow.
The prospect of further research in obtaining experimental dependences of the influence of spool speed, rubber stiffness, geometrical characteristics of the contact gap and pressure on the change of the valve hysteresis is revealed.
TECHNOLOGICAL METHODS OF INCREASING WEAR RESISTANCE AND DURABILITY OF DETAILS
Authors: Trukhanska Olena
Published: January 2021

Improving the reliability and service life of machines, components, units is an important factor in reducing the cost of restoration, downtime of equipment in repair, reducing the number of spare parts.
The introduction of the latest technologies of agricultural production, as well as constant modern improvement, the complexity of agricultural machinery is a natural result of its development.
Parts restoration technologies are among the most resource-saving, because compared to the manufacture of new parts costs are reduced by up to 70%. The main source of resource savings is the cost of materials.
At longtime use of machines wear of details is followed by decrease in operational indicators, causes deterioration of quality of products.
The tractor PTO shaft is subjected to significant static and dynamic loads. The high wear rate is due to constant friction with the grafting disc, gear, inner bearing rings. The production of a new power take-off shaft requires significant costs, so the development of new technological processes of repair and restoration is relevant.
It is rational at restoration of the previous sizes and return of a detail of normal mechanical properties. The remanufactured part is consuming its life, like a new part, and may exceed the service life of the new part.
With the increase in the equipment of agricultural production with more advanced equipment, the conduct of complex mechanization and increasing the efficiency of the use of equipment, repair production is developing and changing. The development of the field of restoration of worn parts is based on close cooperation of repair production with branch and basic science, and achievement of scientific and technical progress.
A promising direction of restoration technology in the organizational plan is the deepening of the method of group restoration technology - the creation of a unified group equipment for the restoration of surfaces. It is established that the majority of details of the restored cars are rejected at the expense of insignificant wear of working surfaces, making no more than 1% of initial weight of details. Experiments and practice show that the repair of agricultural machinery is technically impossible to avoid. Most worn parts have a high residual value: their restoration consumes 20-30 times less metal and materials than the manufacture of new ones, which is economically feasible.
Problems are considered: the choice of technological process of restoration, the choice of technological equipment, tools.

MODERNIZATION OF THE DESIGN OF THE MIXING AND FUEL SUPPLY SYSTEM FOR TRACTOR DIESELS FOR BIOFUEL OPERATION
Authors: Anisimov Victor , Ryaboshapka Vadym , Yelenych Anatoliy
Published: January 2021

In diesel engines, the combustion process takes place over a very short period of time (0.001 s). As a result, complete and timely combustion of fuel and good use of the air available in the engine cylinders can be achieved only with very high-quality mixing. The use of biofuels in modern diesel engines causes a number of problems associated with changes in the parameters of fuel supply and mixing. All types of fuel have different characteristics: density, viscosity, lubricating properties, self-ignition temperature, compressibility and. in this regard, the laws of fuel supply: spraying, combustion, will be different.
The viscosity of biofuels is higher than that of diesel fuel. For this reason, its capacity through small holes in the nozzle of the nozzle (dh= 0.25...0.40 mm) lower than diesel fuel. Due to the small diameter of the holes in the nozzle nozzles and the increased viscosity of biofuels, the nozzle holes are quickly coked. At the same time, the shape and direction of the jet initially changes, and then the hole is completely coked and the fuel supply stops. Thus, for high-quality operation of the diesel engine on biofuels, it is necessary to modernize the design of the mixing and fuel supply system. This problem can be solved by using systems with separate combustion chambers, i.e. using vortex chamber mixing.
In the vortex chamber, 60-80% of the fuel burns, the pressure increases and the burning torches of the fuel flow at high speed into the main over-piston plane of the combustion chamber, where there is a significant supply of air that is not used during the combustion of the charge in this chamber. At the same time, oxygen from the air is well used, and the operation of the diesel engine becomes more efficient at relatively low values of the excess air coefficient at the nominal mode and less toxicity of exhaust gases than for single-chamber diesels.

FEATURES OF THE STAND AND METHODS FOR EXPERIMENTAL STUDIES OF PUMP-DOSING PUMPS OF HYDRAULIC STEERING SYSTEMS OF SELF-PROPELLED VEHICLES UNDER THE ASSOCIATED LOAD
Authors: Motorna Oksana
Published: January 2021

The article discusses a special stand for experimental research of dosing pumps of hydrostatic steering systems of self-propelled machines, which makes it possible to analyze the quality of the dosing pump under conditions that correspond to different control actions and loads that arise during the operation of the steering system. An electro-hydraulic scheme of the stand has been developed to determine the characteristics of a dosing pump under the action of a associated load. The characteristics of control and measuring devices for determining parameters that are controlled both in statics and in dynamics are presented. To record changes in signals over time, a recording system has been developed that realizes the recording of signals on a computer and their processing using the «PowerGraph» program.
A feature of this stand is that the load for the dosing pump is formed in the form of a pressure drop in its outlet channels. This makes it possible to evaluate the performance of these products regardless of their working volume and facilitates the experimental study of the behavior of the system when reproducing certain modes of its operation over a period of time that is not limited to the stroke of the executive hydraulic cylinder of the steering system.
The stand implements an original technique for reproducing the associated load in the outgoing channels of the dosing pump, for which an additional pump driven by a hydraulic motor is installed in the outgoing channels of the metering pump. Regulation of the speed of rotation of the drive motor makes it possible to set the required value of the associated load.
The method for determining the quality indicator of the dosing pump operation under the action of a associated load is briefly described In this case, the indicator of relative flow rates in the outgoing channels of the metering pump is determined, which shows how many times the actual flow rate of the working fluid increases in comparison with the nominal one, which is determined for the dosing pump with a certain working volume by the speed of rotation of the input shaft.
IMPROVEMENT OF TECHNOLOGICAL PROCESS OF DRILLING THIN SHEET STEELS
Authors: Ostrovsky Anatoliy
Published: January 2021

This article considers the technological process of drilling holes in sheet metal. The existing typical technological process, with detailed analysis, provides grounds for substantiating the idea of an innovative solution. There is a connection between the improvement of economic indicators of this technological operation with the change of geometric parameters of the tool.
The comparison of existing technological processes, operations, and transitions of production of round openings with the use of spiral drills is given. The traditional technique involves a clear sequence of the technological process with the use of tools for marking, kerning, and sequential use of screw drills of different diameters.
Therefore, after the previous operation of marking the center of the two holes, perform the operation of kerning. The core (recess in the metal) prevents the deviation of the small diameter screw drill from the marking lines. After the above steps, the traditional technological process involves drilling a small diameter hole in order to direct the main tool in the right direction. To make the main hole perform special sharpening of the working part of the twist drill so that the diameter of the Central part of the tool is equal to the diameter of the first guide hole to avoid further displacement of the main hole and the next operation is to drill the hole to the desired diameter.
As a result, the article raises the topic, given the widespread use of sheet metal, including in the agricultural sector, the feasibility of using an innovative idea to improve the technological process associated with the processing of sheet material, namely thin metal sheets. It is worth noting that for example, we consider a material that is characterized by its versatility, namely steel Ст 3. Despite the numerous sources devoted to the study of improving the drilling process, there are a number of issues, including the extension of this direction surfaces with a covering and without it, various thicknesses within the thin-walled hire. The most significant result of the improved technological process of drilling will be used in the system of efficient maintenance of agricultural machinery.

The article covers the methodological issues of mathematical and statistical evaluation of the information technology use. The necessity of using information technologies to ensure control system flexibility has been substantiated. The impact of the level of integration of implemented information technologies on the increase of production management efficiency through data processing models and use of a single information space has been determined. To achieve the appropriate characteristics of stochastic processes of information technology, it is proposed to use methodological approaches to modeling on the basis of mathematical and statistical evaluation with elements of correlation and regression analysis.
We have established the features of regression model development on the basis of which the estimation of the modeled process is carried out in the forecasting period. The paper investigates the issue of modeling methodology based on correlation and regression models and special cases in their evaluation. The main stages of model development and the sequence of their implementation are given.
The impact on the number of enterprises that use computer technology in their activities, such factors as: Internet connection, the use of social media and the availability of websites has been assessed. Particular attention is paid to the use of social media as one of the key resources in defining the ideology of using information resources. The model parameters were estimated by the least square method. The analysis of the influence of the studied factors has been carried out based on the obtained regression model parameters taking into account their significance on the influence of the process of information technology use. The necessity of theoretical substantiation of interdependent factor effect with the application of variance analysis and mathematical theory of hypotheses has been proved.

The development of modern technologies, equipment for the production of agro-industrial products and the growth of competition in the production of gross crops leads to the fact that farmers are increasingly trying to occupy their own niche. After all, the production of such products does not require special equipment, but allows you to get the maximum profit. Such a niche was the cultivation of crops, which later form condiments and spices. Such production has successfully adapted to market changes in recent years and met domestic demand in this food segment.
Global demand for spices, herbs and spices averages 6,5 million tons per year. 90% of this consumption is provided by Asian countries. Among them, India is a world leader in the production of more than 3 million tons of spices annually. China, Indonesia, Vietnam, Thailand, Bangladesh, Turkey, Pakistan and Nepal also have significant market shares. The European Union produces only 1,7% of the world's spices. This is due to the culinary demand of the region, the peculiarities of the climate and growing conditions. However, the last ten years have shown an increase in the production of spices by 4,3%. This growth is primarily due to the development of food culture and the need for quality food.
The article presents methods of mixing bulk products. There are basically two ways - gravitational and forced (mechanical). The first is carried out under the action of gravity in drum, tray and hopper mixers, the second in auger and vane. Many years of production practice have shown that static mixing methods do not achieve homogeneity, do not increase the activity of the components, there is a change in the particle size distribution of the mixture. Satisfactory quality of mixing is observed only at small degrees of filling of the chamber that leads to increase in dimensions and weight of the mixer.
The scheme of the vibrating mixer which can be widely used in food and processing productions is offered.

There is known equipment for mixing of heterogeneous food mixtures analyzed in this article. Some part of this equipment provides qualitative mixing at macro-level (mixing of large portions of processed material), for example, paddle, propeller, turbine, anchor, screw, gravitation and drum mixers. Another part of mixing machines on the contrary, allows to achieve of effective micro-level mixing (mutual movements of adjacent particles of material) – vibratory and centrifugal mixers. In some cases there is important to provide well mixing both at macro- and at micro-level, when it is accompanied by thermal, diffusion or chemical processes and from its efficiency depend energy expenses and qualitative characteristics of product. Therefore, a task of elaboration of schemes of improved apparatuses for effective macro- and micro-mixing of dry and liquid multi-component food materials is resolved in the article. Authors are proposing to create these apparatuses at the base of well known equipment – gravitation and screw mixers by way of their additional equipping with serial electromagnetic vibro-exciters of ultrasonic oscillations. As a result, a main drive of a base mixer will provide working process at macro-level and an additional drive – micro-level movements of material particles. The proposed apparatuses have a simple and reliable construction, don’t consist of original parts and at the same time, provide necessary efficiency of working process. Equations of movements of processed components particles in course of their different loading stages, with examination of physical-mechanical properties of the components are also presented in the article. These equations can be used as a base for further creation of methods of design calculation of proposed apparatuses.
