In particular, they are widely used in confectionery, oil and fat, flour milling, pharmaceutical, chemical, fodder, paint and other industries. To ensure the safety of the walnut crop, it is necessary to condition them. Moisture requirements for whole walnuts are not higher than 10%. Moisture content of whole nuts after harvesting can reach 35-45%. Therefore, it is necessary to carry out drying to bring them to condition. Drying of whole nuts in Ukraine is usually carried out under natural conditions in covered, ventilated rooms. This is due to the fact that it is physically difficult to significantly speed up the process of drying whole nuts with the help of special equipment. In addition, it is economically inefficient, as it requires significant expenditure on energy carriers. However, if the volume of walnuts is significant, it is difficult to do without special drying equipment. Therefore, some enterprises apply forced drying of whole nuts with the help of various drying chambers in order to prevent their spoilage.\u0000The purpose of the research is to justify the structural and technological scheme of a convective dryer for walnuts and carry out a simulation of the technological process of drying.\u0000Based on the results of the research, the structural and technological scheme of the convective dryer for walnuts, which is made in the form of a mixer with a vertical screw working body with a lower flow of warm air, has been developed and substantiated.\u0000Using the Star CCM+ software package, the technological process of drying was simulated in the developed convective dryer. A visualization of the process of redistribution (mixing) of walnut fruits in the drying chamber under the action of the screw working body and the distribution of air flow speed and temperature in the drying chamber of the convective dryer was obtained. According to the coefficient of variation, it was established that the quality of mixing is the best (δ = 0.92±0.02) and remains at this level after 392 s from the moment of the start of rotation of the screw working body. It was established that there is a temperature gradient in the working area of the dryer: the temperature in the lower part is 58±2 °С, in the upper part - 43±2 °С. Given the rather fast mixing (392 s), such a temperature difference is not critical.\u0000For a more detailed substantiation of the structural and technological parameters of the developed convective walnut dryer, it is necessary to carry out a full-fledged numerical simulation. It is proposed to choose the following research factors: the angle of the cone-shaped grid, the volume of the drying chamber, the diameter, the step and speed of rotation of the screw working body, the speed and temperature of the incoming air flow. The evaluation criteria should be the coefficient of variation of the redistribution of walnut layers","PeriodicalId":173336,"journal":{"name":"ENGINEERING, ENERGY, TRANSPORT AIC","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122047310","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 open network is laid in the form of temporary pipelines, channels or trays, from which water is supplied by pumps to sprinklers and watering machines. Near cities and large livestock complexes, fields are irrigated with wastewater, which is also used with fertilizers.\u0000Water is supplied to the soil by sprinkling, surface, and subsoil and drip irrigation. Water is broken into drops and distributed over the irrigated area in the form of rain. The size of the drops should not exceed 1...2 mm. Rain intensity should be no more than 0.1...0.2 mm/min for heavy soils, 0.2...0.3 mm/min for medium loams, 0.5...0.8 mm/min for light soils. Under such conditions, raindrops do not damage plants, compact the soil less and do not destroy soil clods, water has time to soak into the soil, and puddles do not form on the surface of the soil. It is important to evenly distribute water over the irrigated field and ensure the specified irrigation rate. Fertilizers are applied at the same time as watering.\u0000Water is also supplied in furrows, in strips or by flooding the entire irrigated area. When irrigating the subsoil, water is fed into the soil through pipes with holes, through mole holes located at a depth of 40...50 cm.

Among which, a significant part of production equipment requires the use of electric motors, the power of which exceeds hundreds of kilowatts. Such electric machines have also become widespread as generating equipment, where they are an integral part of power plants, both using traditional energy sources (thermal power plants, nuclear power plants, etc.), and renewable (hydroelectric power plants, wind farms, etc.), where the unit power of a single electrical machine is usually higher than in other sectors of economy.\u0000When operating such equipment, systems for monitoring a significant number of technological parameters are often used, and in real time it characterizes the modes of their operation. This approach makes it possible to increase the reliability of operation and, with a fairly high probability, to avoid large-scale man-made threats that can be caused by an emergency failure of power electric machines (including powerful electric generators), which are quite often accompanied by the destruction of supporting structures, structural elements of industrial premises and can pose a threat to the life and health of production personnel. But the use of even the most modern systems for monitoring the technical condition does not provide one hundred percent reliability, and when operating electrical machines with a nominal power of the order of units of MW Today, the vast majority of technological processes, both production and agriculture, are based on the use of electrical equipment. A similar situation occurs in the household sector, where we can also note a significant increase in energy consumption in recent decades. Given this, it is obvious the need to ensure the transfer of significant amounts of electricity, which is not possible without the use of transformers and power electric devices, the construction of the lion's share of which provides insulation of live parts and excess heat using transformer oil. Such equipment, in particular, includes: oil transformers, oil and low oil switches, which are characterized by a relatively low cost at sufficiently high rated currents and voltages.\u0000One of the most significant disadvantages of this equipment is the need for constant monitoring of the condition of transformer oil, the physical properties of which largely determine the dielectric strength and overload capacity of the equipment as a whole. The mass fraction of moisture in the latter is one of the key indicators that determine its dielectric and thermally conductive properties. Therefore, the existing technical regulations for the operation of the latter provide for regular laboratory examination of the physical properties of the latter during the technical inspection of equipment, which usually requires quite a lot of time.

Often, a variable value whose value must be maintained constantly or changed according to the desired law is called a controlled value (coordinate). It is customary to call the required value of the regulated value (coordinate) set, and the actual value - current. The difference between the setpoint and the actual value is a deviation or error signal. A set of devices that affect the object of control, maintaining the current value of the controlled quantity (coordinate) equal to the given one, is called an automatic regulator or a dynamic system.\u0000The influence of the regulator on the object with the aim of bringing the current value of the controlled value closer to the set value (or adding the desired properties to the closed system) is called the control influence, and the set of devices and physical environments through which the control influence acts on the controlled value is called the control channel.\u0000The control process carried out by the regulator manifests itself in a change in the set value of the regulated quantity or a deviation of at least one of the unregulated quantities that affect the regulated one through feedback circuits. A change in the set value of an adjustable quantity is called a controlling or internal setting influence, and a change in unregulated quantities is called an external disturbance. The principle of deviation control is to compare the set value of the regulated value (setting) with its current value. In this case, the error signal Δ is used to create such a regulatory influence on the control object that this error, regardless of the reasons that caused it, does not go beyond the permissible values.\u0000In order to protect the environment and reduce the effect of greenhouse gas emissions, regulations are being introduced all over the world that require manufacturers of household electrical equipment and industrial enterprises to produce products that use electricity more economically.

The article is devoted to the development and research of dies capable of significantly (tens or more times) reducing the power of the used forging and pressing equipment due to the use of energy-saving dies that can significantly increase the deforming force. A stamp capable of significantly increasing the deforming force is called energy-saving . The article shows that using different types of levers, it becomes possible to significantly increase the useful force of stamping tools acting on a deformable workpiece. Thus, it becomes possible to use relatively low-power pressing equipment to achieve significant forces of the working tool. Based on the given mathematical dependences of the geometric and power characteristics of the energy-saving stamp, a computer program was developed in MS Excel and modeling was carried out, with the help of which it was studied how the deforming force R changes depending on the change in the angle of inclination of the punches  and the corresponding graph was plotted at a predetermined constant pushing force F = 1 N. After analyzing the resulting graph, it can be argued that a tenfold increase in the deforming force R compared to the pushing force F, which is created by the pressing equipment, is observed at an angle of  = 5.35 degrees, fifty times at an angle of 1.1 degrees. At angles approaching 0 degrees, the increase in the deforming force can reach significant values and is limited only by the strength of the energy-saving stamp itself.
