“…The phases of the technology of drying fodder by air ventilation are: 1. harvesting the furrows of the plants, at a humidity of 80… 85%; 2. drying in furrows until it reaches a humidity of 35… 40%; 3. assembly and immediate transport of feed for storage on the drying platform; 4. finalizing the drying by ventilation with cold air or hot air, until a humidity of about 17% is reached [6].…”

The fodder plants necessary in the field of animal husbandry have an essential characteristic, namely, the full use of plant mass, thus, imprinting their more efficient use in environmental conditions, it is among the intensive crops. The technology of conservation of fodder plants is useful for the capitalization of fodder from meadows and fodder crops, especially from the surfaces in the hilly and mountainous areas. The areas of the exploited meadows must ensure the necessary animal feed throughout the year. The article addresses certain experimental aspects of how it influences the environment of the aeration process in order to dry the fodder plants, a technology based on conservation, storage and maintenance of the nutritional qualities of the fodder. In the technology of drying fodder with heated air, it is necessary to continuously control the temperature in the fodder mass during the aeration process. The results of the experimental research were carried out in a technology to reduce the drying time from harvesting the fodder plants to obtaining hay at the storage humidity. A special aeration installation with a monitoring and control system of work processes was used to carry out the research. During the research the environmental parameters were analysed, the flow and the parameters of the aerating agent (temperature and humidity), as well as the characteristics of the feed mass structure: humidity, temperature, drying uniformity, obtaining information on their influence on reducing the drying time. In the controlled process of feeding aeration, conducted in climatic conditions, there is additionally an influence of the linear speed of the aerating agent on the duration of the process, the degree of humidity of the feed, at approx. 18%, recommended for preservation.

“…Analysis of modern technological equipment for spreading straw bedding (mainly fan type blowers) [4] allows us to draw conclusions that the disadvantages of the existing equipment for the making and forming of straw bedding for box-type housing livestock are high energy consumption of vane technical means and dustiness of the premise [8][9][10]. One of the ways to solve these problems is the usage of a working body for spreading straw bedding material in the form of a rotor with fingers [11][12][13][14][15][16][17]. This issue was studied by such native and foreign scientists: V.D.…”

This article presents methods and results of experimental research to determine the power consumed when driving the working bodies of the straw bedding mobile spreader to cover cow stalls (boxes). Analysis of the design and mode parameters of the rotary finger working body influence on the energy consumption of the bedding material spreading process is carried out. Using the experimental data, it was established that the power consumed to drive the rotary finger working body of the mobile straw bedding spreader, at the tractor power take-off (PTO) shaft rotation speed of 540 min−1, the forward unit speed of 2 km/h, and performance of 1.5 kg/s, is equal to 7.633 kW. In this case, due to the installation of a rotary finger working body for spreading straw bedding, the power consumption increased by 9%. This increase will not have a significant impact on the overall energy consumption of the spreading bedding material working process, because this class tractor power reserve allows its use.

Annotation Purpose. To analyze theoretical research of domestic and foreign scientists on extrusion of plant materials to identify areas for improving the quality of the process. Methods. Methods of mathematical description and solution of models of functioning of machines and mechanisms by branches on the basis of theoretical mechanics, higher mathematics, analysis and synthesis are used. Results. According to the results of the analysis, ways to improve the technology of extrusion of vegetable raw materials by moving to less energy-dependent methods with improved quality of raw materials. Conclusions. The analysis of the studied works showed that from the point of view of rheology, the process of compound feed production in the extruder is little studied; the main works are performed in the field of extrusion of plastics and metals. The result of the analysis showed that all extruders for plastics operate at high temperatures (from 120 to 200 Celsius degrees). Such temperatures for the production of compound feeds have a high energy consumption, which allowed directing the research towards less energy-saturated technical means in extruding technologies. Theoretical research and experimental verification of the proposed technological solutions are planned in the near future. Keywords: extruder, screw, feed pressing, mathematical model.
