The article explores the issues of the objective approach to managing the educational process allowing to effectively update and monitor it. The study is aimed at organizing the processes of control and management of the quality of educational programs with reduced time costs. The authors have researched the processes of methodological support of the educational process and the corresponding documents of an educational organization. An information system for monitoring and managing the quality of educational programs has been developed. The authors have developed models of the problem area, allowing one to determine the bottlenecks in organizing education quality control. The results of the study are meant for the internal audit of educational services and carrying out the procedures of public control, accreditation, or licensing of an educational organization. They allow for the quantitative evaluation of the educational program content and unambiguous interpretation of the obtained result. For this, the authors have developed an objective system for assessing the quality of educational programs. The assessment includes a set of objective indicators with a certain significance: for example, compliance with certain standards, the use of relevant peer-reviewed literature, agreed forms of education, a point-rating system, etc. All criteria are divided into blocks, each of which has a corresponding conformity assessment system. The developed assessment scale unifies the quality monitoring procedure, reduces subjective evaluations, and ensures less time-consuming monitoring of the quality of an educational program at the different stages of its life cycle.

A high yield of grain and green mass of corn can be obtained only when using the seeds of the first generation of zoned hybrids, which are threshed in the conditions of processing enterprises after pre-drying the cobs to a humidity of 12…18 %. At this humidity, the strength of the shell of corn grains is maximal and the connection of the grain with the rod is weakened, which allows for threshing with minimal damage to the grain. An experimental design of an axial-rotary threshing device, which rotor is equipped with multi-helical spiral winding of variable height, is developed. The winding height decreases from the entrance to the threshing chamber to the exit from it. Rotor fully covered pneumatic-adaptive studded deck is installed so that the gap between the rotor shaft and the independent movable pins decreases from the input to the output. All pins are pressed against the deck by means of rubber pneumatic bags with an internal overpressure. In addition, the threshing chamber has the ability to change its spatial position relative to the horizon. These dimensional characteristics are justified foe a stationary axial-rotary threshing device with a productivity of up to 4.5 t•h -1 . As the result of experimental studies, the following rational intervals of values of the modes of operation of the threshing device were established: the rotor speed 150…170 min -1 , the angle of inclination of the threshing chamber 10…14º, the force of pressing the movable pins to the cobs 35…55 N, feed 0.8…1.1 kg•s -1 . As a result, the productivity of the axial-rotary threshing device is in the range 2.88…3.96 t•h -1 and the energy intensity of the threshing process is 0.5…0.7 kWh•t -1 , grain on the cob after threshing is less than 1.5 %, free grain in threshed corn cobs 1.16 %.

The damages of corn grain during threshing depend on many factors, the main of which is timely removal of grain from the threshing chamber what depends on the design of the deck. The functional parameters of the deck in self-propelled combines and stationary threshers used for threshing of seed corn have been studied. Studies of factors affecting the separation process of a mixture consisting of grain and other parts of corn cobs in the threshing chamber were carried out. It has been proved that the shape, size and layout of the deck holes have the greatest impact on the timeliness of the output of the threshed corn grain from the threshing chamber. In this case the deck should consist of three parts of different lengths: 1) a part of the deck of the chamber of the primary damage of the integrity of the cob grain structure; 2) the deck part of the main threshing chamber; 3) the deck part of the finish threshing chamber. The evaluation criteria for choosing the lengths of the deck parts are the average of the double ratio of the linear dimensions of the corn grain of the six main subspecies and the maximum length and diameter of the cobs of 65 main varieties cultivated in Russia. The ratio of the lengths of the first two sections of the deck should correspond to the Fibonacci golden section-1.618 and the double ratio of the linear dimensions of all three sections-1.29. The studies have evaluated the effect of the shape of the holes: round, round lunate, square, rectangular, and hexagonal. At the same time, the pattern of holes on the hexagon and the square and the square holes, additionally, at an angle 45 º to the rotor axis was studied. The feasibility of using round holes in the deck with a diameter of at least 10…14 mm has been established. As a result of using the deck of the proposed design, the conditions for timely removal of threshed grain from the threshing chamber with a reduced probability of damage are created.

Currently, the technological process of grinding stalked feed in a multi-plane horizontal grinding machine has not been studied enough, and the physics of the process remains poorly understood. The purpose of theoretical research is to study the physics of the process of material movement in a vertical-type cutting grinding machine, and the tasks are to determine the absolute speed of particle movement and the vertical speed of material passing through the grinding chamber. The hypothesis of the physics of the process of stalked feed grinding was put forward, an analytical model of the functioning of the grinding machine was developed and the forces affecting the stems in the inlet chamber and the grinding chamber were revealed. Material in the inlet chamber in spiral air flow descends along the screw line onto rotating knives and presses against the inner surface of the grinding chamber, along the perimeter of which segment contradictions are installed. The knives of the grinding drum for each phase make the selection of the material and its subsequent grinding from the impact in flight and when interacting with contradictions. Based on the analysis of the trajectory of particles, the mathematical model and theoretical value of absolute speed of particle movement along the inner surface of the grinding chamber -23.25 m•s -1 , values of vertical speed of material passing through the grinding chamber -3.95 m•s -1 and the dropping angle of the helical line -10º are obtained. The obtained results confirm the hypothesis of the physical essence of the process of grinding stalked feed about the possibility of regulating the vertical speed of material passing through the grinding chamber, the degree of grinding, energy intensity and productivity of the grinding machine. Due to this, the investigated multi-plane horizontal grinder has significant advantages over special and universal hammer grinders of stalked feed.

Modern continuous drying equipment does not allow in one pass of the drying chamber to obtain seed grain of conditioned moisture from freshly released seeds of melon crops. To solve this problem, a high moisture melon crop seed dryer was designed, in which the principle of differential heat supply to forced mixed material was implemented. The design of the drying chamber provides for the supply of a heat carrier to the zone of predried seeds, which withstand a higher temperature, and then at a lower temperature to the zone with high moisture seeds that prevents them from cracking. Design and technological parameters and operating modes of the experimental dryer were experimentally investigated. Studies were carried out by means of a series of one-factor experiments in three stages: determining the productivity of the device for supplying seeds to the drying chamber, studying the transport ability of dryer elastic agitators, choosing a rational angle of inclination of the gas distribution sieve of the unloading device. The following parameters and consistent patterns are established: angle of inclination of gas distribution sieve of unloading device 14º; seed supply to drying chamber 24-18 kg•h -1 ; revolutions per minute of elastic agitators, when the seeds are supplied to the drying chamber 24 kg•h -1 -4 min -1 ; when the seeds are supplied 22 kg•h -1 -4.75 min -1 ; at 20 kg•h -1 -6 min -1 and at 18 kg•h -1 -7 min -1 ; drying agent speed 5 m•s -1 ; specific energy intensity of pumpkin seed drying process was 1.27 kWh•kg -1 with the dryer productivity 18 kg•h -1 . The given research results make it possible to determine the rational rotation interval of the transporting working element, within which elastic agitators provide the required productivity and high quality of seed drying to conditioned moisture in one pass of the drying chamber against the direction of the drying agent movement.
