This article presents the results of research to determine the main technical and economic indicators of a new installation we have created for marinating cocoons with the help of solar radiation energy. The possibility of marinating cocoons both on sunny and cloudy days has been proven through direct and indirect use of the energy of solar radiation. The performance of the installation, the temperature inside the drying chamber and the time for complete marinating of cocoons were determined. On the basis of the data obtained, it can be said that the installation provides complete of marinating cocoons and the use of this installation contributes to 100 percent savings in energy resources spent for freezing cocoons.

This article discusses the construction of a mathematical model of accelerated chemical-technological processes. Usually, in practice, the problem of building models of multi-stage processes, as a rule, is complicated by the universality, uncertainty and nonlinearity of the objects being modeled, the complete or partial lack of expert experience and an analytical description of dependencies. Mathematical models describing chemical technologies are considered to break down the state into discrete stages. The study below allows us to recommend stage processes to be considered as continuous functions.

The paper presents the results of the mathematical modelling of external stimuli to improve the efficiency of the removal of grain material from the grinding zone. Thus, the authors proposed to improve the evacuation conditions of the finished product from the working chamber of the crushing plant, as one of these solutions to improve the grinding process in crushers. As a result of creation of external vibrating influence. For this purpose, the calculation chart for modelling the proceeding process of the crushing plant body movement is created which takes into account weight and sizes of the crusher, weight, angular velocity of rotation and eccentric piece location, as well as rigidity of an elastic suspension on which the crusher is established. For the solution of the posed problem, we used methods of analytical mechanics, the Lagrange equation of the second kind, for the mechanical system with two degrees of freedom. As a result of calculations amplitude-frequency characteristics of mechanical system are determined. The conclusion about the choice of the angular velocity of the eccentric rotation for creation of necessary external stimulating influence on the crushing system and improvement of conditions of evacuation of a ready product from a working zone is given. The resonance frequencies of firstand second-order system vibrations and the vibrator frequency are determined to achieve resonance frequencies. Keywords: vibration, modelling, Lagrangian equations of the second kind, grinding, crushing plant.

During the drying process, the more time the paddy pile is in the dryer, the higher the drying efficiency of the device. Thus, the movement of the paddy along the OX axis is one of the main factors affecting the drying efficiency of the device. Paddy movement along the OX axis depends on the speed of the drying agent. Therefore, in experimental studies, it is advisable to determine the optimal value of the speed of the drying agent in the range from 0,25 m/s to 0,75 m/s. The number of revolutions of the dryer drum provides mixing of the paddy mound. The mixing of the paddy during the drying process is one of the factors that leads to an increase in the drying efficiency of the device. Therefore, it is advisable to determine the optimal value of the number of revolutions of the dryer drum from 16 min-1 to 22 min-1.
在干燥过程中，稻谷堆在干燥机中的时间越长，设备的干燥效率越高。因此，稻谷沿OX轴的运动是影响设备干燥效率的主要因素之一。稻谷沿OX轴运动取决于干燥剂的速度。因此，在实验研究中，宜在0.25 m/s ~ 0.75 m/s范围内确定干燥剂速度的最佳值。干燥滚筒的转数提供了稻谷的混合。干燥过程中稻谷的混合是导致设备干燥效率提高的因素之一。因此，烘干机滚筒转数以16 min-1 ~ 22 min-1为最优值为宜。

Currently, there are great perspectives for the technology of manufacturing products and aggregates from PCM based on prepregs. Thus, the use of prepregs makes it possible to manufacture complex configuration parts in one technological operation. High competition and the increasing necessity of mass production of large-sized parts from PCM determines the emerging need for the use of automated layout equipment. The replacement of traditional, manual methods of layout by automated methods provides significant advantages, such as an increase in the quality of the resulting parts, a significant reduction in labor intensity of their production, an increase in accuracy and repeatability of the technological process of layout (reduction of defects) and, consequently, reduction of the cost of the finished product.

The article is devoted to the optimization of the design of the inlet zone of a centrifugal blood pump. One of the disadvantages of such pumps is the generation of turbulence in the flow of the pumped fluid, which contributes to high blood hemolysis. The reason for turbulence lies in a combination of geometric and kinematic factors, in particular, a 90 degree turn of the flow in the inlet part of the impeller channels and a high circumferential speed of rotation of its channels. The hydrodynamic consequence of this is an increase in the hydraulic resistance of the pump flow path and separation of the boundary layer from the streamlined surface. As a result, the non-uniformity of the flow velocity field increases and separation flow zones appear, stimulating vortex formation and turbulence of the blood flow. The article provides the derivation of an equation for calculating the optimal diameter of the impeller D1, which does not have a bushing in the inlet. This design is typical for centrifugal blood pumps. As a criterion for the optimal value of D1, the minimum level of hydraulic resistance in the inlet zone of the pump was considered. Based on the derived formula, a graph of D1 values was constructed in the range of parameters: blood volume flow 3…6 liters per minute, speed 4000-10000 rpm. With an increase in blood flow and a decrease in the number of revolutions of the impeller, the diameter of the inlet to the impeller must be increased from 6.4 mm to 13.8 mm.
