This article deals with the rules of observance of agriculture technology requirements for the production of potatoes in particular. On the example of the combine PDA 1.2, we have considered the places having the greatest damaging effect on roots. One can also find a summary procedure for calculating the probability of defective products

This article deals with the present level of harvesting and transport operations in the production of potatoes and methods of improving the operational and technological parameters of machines with which they are carried out by introducing into their design of innovative devices

The research results presented in this article are intended to familiarize themselves with promising avenue to improve the quality of potato harvesters by improving the process of separation, as well as working bodies for its implementation

The mathematical model presented in this article is designed to assess the probability of occurrence probability of technological failure potato harvester according to the specific conditions and usage

The mathematical model presented in this article allows you to choose rational values and ranges of design and technological parameters of body separation, as well as their further optimization

We have presented the technological scheme of a dispersal device which allows to increase the efficiency of cleaning and disinfection of automotive vans with specialized solutions

For cleaning and disinfection of motor vans we can effectively apply installation for the treatment of work surfaces with a disinfectant spray. Disinfection unit is a generator of hot mist with a device for dispersing

The most labor- and energy-intensive part of potato machine production technology is harvesting which is done mainly with harvesters. Modern potato harvesters meet the required efficiency data in favorable conditions. In erroneous conditions (primarily characterized by high or low soil moisture) the efficiency of separating the tubers from impurities is reduced, and the loss and damage of the products increase. This situation is due to the imperfection of the separation device of potato harvesters. Up to 1000 tons of soil per 1 ha is separated at the separation device in the process of harvesting. As a result, the potato harvesters capacity on the whole is determined by their separators output. Nowadays, rod elevators are most widespread and used. One of the main drawbacks is the significant increase of tubers damage in a case of low soil moisture mainly caused by the contact of the tubers pile with the side frames of the harvesting machine. From the above reasoning, one can confirm that the increase of capacity and functioning quality of potato harvesters’ separation devices is an urgent scientific-and-technical task of agriculture

The effectiveness of disinfection depends on used disinfecting materials for vans, their actions and technological parameters of the installation for applying disinfectants. Hot mist generators provide uniform distribution of particles of disinfectant solution inside the van for transportation of agricultural products. The parameters of the generator of hot mist affecting the quality of disinfection were investigated. Tests were conducted for the vans used to transport agricultural products. For studies we used the vans in operation, which transport farm animals (pigs) and had been disinfected before. Sampling for the research on contamination was performed with pre-prepared swabs. Factorial experiment was planned with using scheme #32, and as a result of significant factors in the univariate experiments we set a temperature of the aerosol disinfectant solution and the duration of surface treatment. As an optimization function we have chosen disinfection efficiency of bodies of vehicles carrying agricultural products. Comparing the results of the experiments on different groups of microorganisms we have found that the optimal mode of hot mist generator with a dispersing device are: the processing time of 1 m2 - 8.5 at the processing temperature - 65º C

Based on the previous investigations we have underlined the need to increase fruit and vegetables preservation quality while transporting them from the producer to the consumer at the expense of improving the road transport operation for its intended purpose. We have made a conclusion about the need to develop strategies for maintenance and repair as for the actual technical state at the expense of developing the diagnosis system based on the development of a math model of changing the technical state of the diagnosis object, developing a method of rational set of objects to be diagnosed and determining the technical state optimal control frequency. We have confirmed that the above mentioned is possible when considering the system of technical operation of road transport as an organization-production system and applying the engineering-cybernetic approach to improve this system. We have considered the basic requirements for the efficiency indexes when investigating and improving the operation system that will allow achieving the aim we have had and can be described mathematically. We have made a conclusion about the urgency of the issue we studied and the possibility to develop the efficient operation system of road transport based on the provided criteria
