Feed production, feeding of animals and poultry is an integral part of animal husbandry and poultry farming. Proper feeding of animals and poultry, which implies the making of an optimal diet with the input of useful premixes and vitamins, can increase their productivity. In Russia the predominant type of feeding is complete feed, which includes compound feed. Regardless of the type of feed in the process of its production, it is necessary to observe the proportions of its components. Dispensers are used for dosing, which depending on the purpose, are divided into mass and volume. We have made an attempt to generalize, systematize and implement the accumulated experience in the form of a scheme that allows us to understand the principle of operation of modern systems for dosing feed components, in which augers are used as feeding mechanisms. The purpose of the research was to build a scheme for selecting parameters and develop a methodology for studying the dosage system of feed components based on it. The results of the analysis of intellectual property protection documents and scientifi c works in the fi eld of dosing have been used to make a scheme for selecting parameters of the feed components dosing system. The results of observations on the operation of the developed system under production conditions and design features have been also taken into account. As a result of the research developed the scheme of selection of the operating parameters of the dosing system, revealed its shortcomings in the form of lower dosing accuracy with the decrease in the mass of the weighed components and the long search settings when composing the new diet. The methods have been developed to address the identifi ed defi ciencies in the determination of limit values of technological parameters.

The article presents an approach to the formation of a decision support system in the management of energy consumption of production technological systems. Such systems allow the company to detect and respond in a timely manner to the appearance of hidden energy losses, to carry out organizational measures aimed at energy saving and to optimize the timing and scope of repair and restoration work. The approach is based on the modeling of stationary sections of energy consumption, presented in the form of precedents, their accumulation and subsequent analysis in the space of influential technological parameters. In addition to the base of precedents, the system includes software modules for assessment and formation of the profile of hidden energy losses, modules of technical condition, forecast and formation of precedents. The analysis of precedents consists in the selection of similar cases of energy consumption, the formation of efficient energy consumption functions and the calculation of energy losses with its help. Hidden energy losses can be calculated in real time for all technological systems of the enterprise. This allows you to build a profile of energy losses of the enterprise. The advantage of this approach in comparison with the known ones is that it allows to adapt to technological systems with different energy sources. The article emphasizes that the method can work with the energy manager with both linear and nonlinear dependence of energy consumption on process parameters. However, the limitations of this approach are noted. Thus, the determination of latent energy losses and technical condition of the equipment requires the participation of qualified specialists of the enterprise, who must be able to analyze the results and propose measures to eliminate energy losses.

Aim. The experimental determination of rational parameters and modes of the vibrational digging-up working tool to ensure the required quality of conducting the technological process of digging sugar beet from soil. Methods. The methods of planning a multifactor ex- periment, fi eld studies, statistical processing, regression analysis of the experimental data with building graphic curves were applied. Results. A new model of a tool for vibrational digging-up of sugar beet from soil has been elaborated. The accepted program and method were used to conduct experimental research on the impact of the main construction and technological parameters of the vibrational digging-up working tool of the beet harvester on the quality indices of performing the technological process of harvesting sugar beet. The energy parameters of new vibrational digging-up working tools were studied in fi eld conditions via registering the values of tenzometric sensors in different modes of the device and different parameters and working modes of the vibrational digging-up tools. Conclusions. It was established that there is a value of the vibration frequency and running depth in soil of the vibrational digging-up working tool for each value of the translational veloc- ity of the vibrational digging-up machine which corresponds to minimal losses and damage to crop roots. It was also found that the degree of crop root damage depends on the conditions of performing the technological process of vibrational digging-up (soil solidity and humidity), and the weight of damaged crop roots increases with the increase in solidity and the decrease in humidity of soil.
