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.

Theoretical prerequisites for studying the seeds ozonation

The paper presents the theoretical prerequisites for studying the problem of seeds ozonation. The analysis of scientific papers describing the results of experimental studies in the field of agricultural crops seeds ozonation has been carried out. Based on this analysis, the theoretical system for determining the seed germination after treatment with ozone has been proposed. This theoretical approach can be useful for studying the ozone concentration effect on seed germination for further agricultural crops productivity improving.

The impact of variability of the type of Siberian cedar by seed scale apophysis on the seed peel firmness

The seed peel firmness of Siberian cedar morphological forms (by seed scale apophysis) has been studies. The existence of differences on the seed peel firmness indicators between the forms is theoretically based by the nutcracker’s activity. The results of the experiments prove the given assumption. It is shown that nuts from the cones with plain apophysis type require the relatively less maximum power and tension, but more time on their cracking. To use the seeds of the given morphological trees’ forms is prospective for the production of cedar kernel.
