The technological process model of post-harvest grain processing

A large number of technological operations and technical means, the complex nature of relationships between individual operations make it necessary to consider post-harvest grain processing as a large or complex system. In the article the technological process model of post-harvest seed grain processing that is applicable for the analysis of the factors determining a technological process, scientific justification of ways and methods that save energy at post-harvest seed grain processing is presented.

Formation of steadily productive annual mixed sowings based on optimization of mineral nutrition

Complex researches have been conducted in the Tver region on sod medium podzolic sandy loam well-cultivated soil. We have studied implementation of crop yield programmable levels by means of vetch-barley-oats mixtures different in composition. The advantage of their cultivation on grain-and-hay has been revealed, when the program both at the background of 2.5 thous. feed unit /ha and 5.0 thous. feed unit /ha on all variants of mixed crops was exceeded. Program has been carried out only at the programming level on 2.5 thous. feed unit / ha when growing mixtures for grain.

Study of fodder grain grinder rotary centrifugal type with various working items

The experimental studies results of fodder grain grinder rotary centrifugal type with different working bodies (knives) are presented in the article. They The optimum geometrical form of fodder grain grinder is determined taking into attention minimum energy consumption for grinding and adjusting the particle size of grain on leaving a chopper.
