Description
This article studies the influence of various methods of thermal, acoustic and electromagnetic exposure on free lipid content, acid and peroxidation number of oil in sunflower seeds during their after harvesting ripening. We have investigated the influence of traditional and microwave heating on lipase activity of seeds. We have also founded the most efficient conditions for the rate and the temperature of microwave heating of freshly harvested sunflower seeds and determined their effect on the rate of drying

Description
The purpose of work is increasing the efficiency of the inertial conveyor by applying the link of preacceleration of the linear induction electric drive (LIED). One of the tasks is creation a mathematical model and its research. LIED design with the link of preliminary dispersal was chosen during the work, its installation coordinated on the inertial conveyor. The mathematical model created and its researches conducted. The results of the researches confirm the increasing of the efficiency of the inertial conveyor
