The article analyzes the effect of particle size of corn and wheat middlings on energy costs at temperature cooking. It shows a graphical depiction time of cooking on the particle size of middlings grits. We have also defined the equivalent diameters of seed corn and wheat. We have found that the minimum energy correspond to a particle size of 1 mm, is widely used in alcohol plants in Russia
In the article, we have described an electro solar water heating system for agricultural consumers. The results of computer modeling in the “Modeling in technical devices” software package have been given
Constructive-technological parameters of a hopper feeder have been established. They help to synchronize feeder’s flow and feed consumption by animals. Synchronization of these factors eliminates the initial cause of feed loss during fattening. It was found out that the main influence on feed loss is exerted by shape and geometrical parameters of feedstuff fill at the bottom of feeder, which depend on their physical and mechanical properties and on the feedstuff level in a hopper feeder. The fill balance condition at the bottom of a feeder is provided by compensation of feedstuff weight pressure inside a hopper due to the weight of a surcharge layer. The thickness of layer is proportional to the height of feedstuff volume inside a hopper and does not depend on technological gap between discharging feed line and the bottom of a feeder. It is found out that the discharging feedstuff is distributed throughout the bottom of a feeder. There is a central nonmoving area in the cone shape in alignment with the axis of the discharging feed line. This area functions as a shutter, which reduces the effective area of discharging channel. It is determined that the flow of feedstuff is set by adjusting the technological gap between discharging feed line and its bottom within defined limits. In accordance with physical and mechanical properties of feed this dependence of feedstuff flow allows to determine corresponding functional parameters of discharging feed line in order to meet the needs of a group of fattening animals
In this article we have considered the possibility and the availability of cold plasma technologies application in different branches of industry. The investigations of cold plasma treated water in potato growing technologies which have been conducted in PetrSU at the Agricultural faculty are described. The basic parameters of the device for water with cold plasma treatment are shown. The results of experimental investigations about cold plasma treatment of water influence on potato growth and yield are presented
To solve the problem of reprocessing and use of rubber waste in Russia it is necessary to develop and adopt a set of measures regulating the procedure for their accounting, collection, storage and delivery for processing, as well as preparation and promotion of legislative acts at federal and regional levels, stimulating an increase in complete renovation and recycling of used tires. Russia has seen a steady increase in quantity of waste; fundamental changes to this trend in the nearest future are not expected. This is obviously due to the growth of industrial production and the level of final consumption. In this case, wastes of consumption will grow faster than production waste due to advanced growth of products of final consumption - primarily household, computer and electronic equipment, household items, clothes, cars, etc. [2]. There are several methods of used tires and rubber waste reprocessing in general, but we focus only on the pyrolysis process, as one of the most efficient and environmentally friendly. Pyrolysis is thermal decomposition of many organic and inorganic compounds. In a narrow sense, the natural decomposition of organic compounds with air deficiency. In a wider sense - decomposition of molecular entities constituting less heavy molecules or elements under the action of raising the temperature
The article presents a study of parameters and modes of operation of machines for soil cultivation. In determining the parameters and modes of operation of machinery for tillage we have applied the theory of similarity and dimensions of physical quantities. We have obtained the regularities of disclosing the relationship of the parameters from the medium to the energy characteristics of the process. As the initial data we used test protocols of machines for soil cultivation (Central - Black Earth, Kubanskaya, Sibirskaya, of North - Caucasion MIS, RosNIITiM) : KPI - 3.8, AРC - 3.9, AKV - 4, AKM - 6 - V, AMP - 4 APC - 4 A, AРC - 10 APR - 4.4, APU - 6.5 APSH - 6 , CNC - 6.0, CSТ - 3.8, APC - 4. We defined the formula оf dimension parameters and modes of operation of machines for soil cultivation and properties of soil (traction resistance, depth, width, speed, hardness of the soil, acceleration). Based on dimension theory we have received similarity criteria. Based on the correlation analysis and the least squares method we determined the nature of addiction and the coefficients for it. We have also received a graph for determining the operating modes and parameters of machines for soil cultivation
