INJURY AND QUALITY GRAIN CROPS SEED DURING THE TECHNOLOGICAL PROCESS OF THE PREPARATION
Abstract
The production and provision of people with quality food becomes especially important due to the increase in population of the planet in the next 20-30 years to 10 billion people and the deterioration of the ecological state of the environment namely the pollution of soil, water and air. Therefore, the production of 100 million tons of grain in Ukraine is an important task of nationwide scale. A prerequisite for its implementation is the preparation of at least 2.5 million tons of high quality seeds which largely depends on the availability of technical facilities and technological capabilities of the national agro-engineering branch. The main purpose of the research is to obtain high quality seeds for all technological processes of their preparation from harvesting to sowing by reducing grain macro- and micro-traumas and improving the optimum performance of various technical means namely design improvements and modernization. As a result of research it is established that injury of seeds during technological process of their preparation depends on quantity of loading, properties of components, technical characteristics of technical means and their working bodies, in particular speed of movement, rotation, placement of turns, diameter, angle, material, etc. The number of injured grains increases when tilting the turns of the auger conveyor during mordanting more than 15 ° and the rotation of the mass in the cabinet during the process at a speed of more than 6 rad. s-1. In the direction of future research of the working bodies of various technical means influence on the technological processes of high quality seeds preparation, it is necessary to conduct them in a complex and interconnected way.
