PROCESS EVALUTION OF SEEDS PRE-SEEDING TREATMENT WITH INFRARED RADIATION
05.20.00 Processes and machines of agroengineering systems
Description
The main subject spotted in this article is a calculation method which helps to depict optimal temperature conditions for seeds stimulation by infrared radiation useful for electromagnetic processing and seed-pelleting with perlit next. The analysis helped to depict that the convenient technical aspects of shortwave infrared radiation is in range 0,76-1,4 mcm. This kind of infrared radiation has the greatest penetrating power into the grain to stimulate. According to the methodology a rapid increase of the temperature of seeds after the critical point reaching during IR treatment leads to the properties deterioration of the of thermolabile materials. The temperature gradient during the IR treatment of seeds has the opposite direction of moisture content and depends on the preliminary humidity of the material. This affects the pre-planting cultivation quality of seeds. To avoid overheating and seeds damage there was a mathematical model of the optimal temperature of the IR radiation calculated. As the result of this method there was obtained the calculation of temperature conditions for IR treatment and heating rate depending on seeds humidity. This calculation method helps to define optimal temperature conditions to avoid harmful influence on seeds due to heating. There was data fitting during this method creation and evaluation which defines the effectiveness and perspective of this elaboration
