Therefore, this scientific research is aimed at minimizing the consumption of energy resources by technological machines – crushers and improving the energy efficiency of the process in general is an urgent issue. \u0000A powerful modern research method of studying complex objects is system analysis, which enables to modernize existing machines and design new ones without conducting a large number of expensive physical experiments. Unfortunately, this method is not yet widely used in the research and design of new machines for processing agricultural products, since there are no developed and substantiated engineering theories describing the behaviour of the processed material in the workspace of the technological machine.\u0000Grinding grain with a moisture content indicator at the level higher than the base condition, there is a low efficiency of the method of impact grinding, that is determined by the increased plasticity of the material and an increase in the value of the marginal deformation, which can lead the grain towards destruction. A partial solution of this problem is possible when combining the method of cutting and hammering, which has formed the basis of a technical solution implemented in the scientific laboratory of Vinnytsia National Agrarian University, where the design has been developed and experimental verification of the vibrating crusher have been carried out.

Such a solution was proposed to stabilize the hydraulic movement of the cut off wave flow due to the reflective surface of a certain geometric shape for the forced direction of the cut raw material to the heating surface. Autonomous heating of the reflecting surface additionally provides a temperature effect in the conditions of movement of raw material particles after cutting.\u0000As a result of the analysis of the experimental and theoretical parameters of heat transfer, the criterion equation for the heat transfer coefficient of the evaporator with the proposed film-forming element, which has a reflective heated surface for calculating the heat transfer coefficient from the working surface to the raw material, is substantiated. The resulting equation takes into account the influence of the vertical component of the motion of the raw material film, the centrifugal movement during the rotation of the film-forming element, the mixing of the boiling film of the raw material with steam bubbles, the geometric characteristics of the film-forming blade on the hydrodynamic flow of the raw material.\u0000Calculation of a rotary-film evaporator using a criterion equation and a useful heat exchange surface of 0,75 m2 was obtained. The specific metal content in a rotary-film evaporator with a film-forming element having a reflective surface is 57 kg/m2 compared to the vacuum evaporator traditionally used in canning industries 410 kg/m2, which is 7,1 times less. Also, the duration of the temperature effect on the raw material is reduced: a rotary-film evaporator - 200 s and 3600 s in a traditional apparatus. The obtained data will be useful for designing rotary-film apparatuses of various geometrical parameters using hinged blades with a reflective plate.","PeriodicalId":173336,"journal":{"name":"ENGINEERING, ENERGY, TRANSPORT AIC","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115199028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The operation of the internal combustion engine is accompanied by the formation of emissions of sulfur dioxide and nitrogen oxides, which is the cause of acid precipitation. Smog and the greenhouse effect due to hydrocarbon emissions are inevitable, and solid dust and soot particles cause weather changes (cold, fog and rain).

It is only a means of obtaining the information needed by the management system to make a particular decision, behavioral strategy or management strategy. As a result, the recognition system must be designed in such a way as to ensure the greatest efficiency of the control system above the recognition system.
