The technological value of sunflower seeds is determined by their oil content. Therefore, it is important to preserve the quantity and quality of oil. Under optimal drying conditions, the oil content in sunflower seeds increases. Therefore, the question of selecting technological equipment for the drying process arises. Analysis of the mechanical and technological parameters of series-produced dryers showed that these machines are mainly intended for the processing of grain crops. The disadvantages of well-known mine grain dryers are low moisture removal during one pass of the material through the dryer, overheating of the seed and a decrease in its quality in the area of contact with the surface of the intake boxes, increased fire hazard. Drum grain dryers when drying sunflower seeds are very fire-hazardous and do not allow obtaining seeds with uniform moisture content, and the use of high-temperature modes leads to a decrease in the sowing qualities of seeds due to overheating. When drying sunflower seeds in recirculation type dryers, it is very important to evenly distribute the seeds over the entire cross-section of the chamber, as well as to prevent the accumulation of oil dust in the heating chamber and to eliminate the ingress of sparks from the furnace into the heating chamber. One of the promising methods of drying bulk materials is the method of drying in a vibrating fluidized bed, which can be achieved on vibrating dryers of various types. A number of experiments were conducted to substantiate the technological and technical proposals for the process of drying sunflower seeds and to determine the operating parameters of the dryer. Based on the results, graphs were constructed. The results of the research proved the expediency and necessity of using vibrating dryers during drying of sunflower seeds. The best parameters of the infrared radiation drying process with a selected wavelength of 1,5-3,0 μm , a sunflower seed layer height of 15 mm, and a heat flow density of IR radiation were found. 5 kW/m 2 , the height of the placement of the IR generator blocks relative to the layer of the irradiated product is 25 mm, while the drying time will be 11 minutes.","PeriodicalId":173336,"journal":{"name":"ENGINEERING, ENERGY, TRANSPORT AIC","volume":"6 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139187549","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}

From the point of view of zootechnics, it is important not only to include in the fodder mixture the components provided for by the diet in the required ratio, but also to ensure an even distribution of all components throughout the volume of the mixture. The homogeneity of the mixture ensures the same nutritional value of the feed in all parts of its volume.\u0000Currently, when creating a new generation of mixers for dry fodder mixtures, preference is given to rotating mixers. The advantages of mixers of this type compared to stationary intermittent mixers of any type are: a reduction in feed unloading time, a fully automated chamber cleaning cycle, the absence of stagnant zones and rubbing parts.\u0000The purpose of the research is to determine the rational structural and technological parameters of the intermittent rotary mixer and to study the change in the homogeneity of the mixture when varying their values.

As research factors, we accept the following parameters: angle of inclination of the blade α (0 °, 45 °, 90 °), mass of material m (0.1 kg, 0.2 kg, 0.3 kg), rotation frequency n (30 rpm min, 60 rpm, 90 rpm), mixing duration t (1 min, 3 min, 5 min).\u0000Experimental studies were carried out on a laboratory installation of a periodic rotary mixer.\u0000As a result of numerical modeling and experimental studies of the mixing process in a rotary mixer of batch feed, the dependences of the change in the homogeneity coefficient of the mixture in the mixer h on the angle of inclination of the blade α, the mass of the material m, the rotation frequency n, and the duration of mixing t were established.

An analysis of the main malfunctions of structures that occur during the harvesting of grain, leguminous and other crops, both of the combine itself and of the headers for them, was made. This is especially emphasized during harvesting with high humidity, which significantly worsens the conditions for harvesting crops, and thereby increases the likelihood of frequent emergency stops of grain harvesters. Constructive and technological solutions have been revealed that allow harvesting various crops with minimal possible losses. Based on the given analysis of structures, the possibility of effective use of grain harvesters during the implementation of agrotechnical evaluation indicators, i.e. productivity, throughput capacity of the thresher, grain losses, as well as the avoidance of regular stoppages related to malfunctions, which should be paid special attention, is considered. CLAAS LEXION combine harvesters designed for harvesting grain, legumes and other crops, including soybean and rapeseed, are the basis of the analysis. The analysis of the main malfunctions and ways to improve the performance of CLAAS LEXION combine harvesters shows that during their use in production conditions for harvesting grain, legumes and other crops, positive results, high quality and reliability of work will be obtained, and at the same time increasing productivity due to the avoidance of emergency stops.","PeriodicalId":173336,"journal":{"name":"ENGINEERING, ENERGY, TRANSPORT AIC","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116410523","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 physico-mechanical properties of seeds include: size and shape, aerodynamic properties, surface condition, specific gravity, porosity and flowability of the grain mass, packing density of the grain mass, bulk and absolute weight, color, hydraulic resistance.\u0000The chemical and mineral composition of rapeseed was analyzed, it is rich in oil content (40-45%), proteins (25-26%), and also rich in potassium (979 mg) and phosphorus (840 mg).Hygroscopic characteristics include studies of the equilibrium humidity of rapeseed under the influence of relative humidity and air temperature. The need to dry rape to 8% reduces biochemical processes in the middle of the material, which improves the quality and does not spoil the seeds. Thermophysical characteristics increase with an increase in the temperature of the coolant and the moisture content of rapeseed. Formulas for calculating the specific heat capacity and thermal conductivity coefficient of rapeseed from the humidity of the material and the temperature of the heat carrier are given. To determine the qualitative characteristics of rapeseed, a method of determining biochemical parameters is presented. Determining biochemical indicators such as germination and germination energy of rapeseed before and after drying allows finding rational regimes. Determined factors of intensification during drying of rapeseed are as follows: increase in driving force, increase in kinetic coefficients, increase in the contact surface of the grain with the coolant. An increase in driving force due to an increase in the difference in moisture content and temperature of the coolant and grain. An increase in the kinetic coefficients is achieved due to an increase in the coefficients of heat transfer, thermal conductivity and drying. An increase in the contact surface of the grain with the coolant is possible due to the activation of the surface and the creation of a loose, pseudo-liquefied or suspended grain layer.","PeriodicalId":173336,"journal":{"name":"ENGINEERING, ENERGY, TRANSPORT AIC","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126140248","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}
