Course abstract
The aim of the course is to master the basic principles, technologies and techniques of conditioning of agricultural products: pouring of the materials, volume mass, friction coefficient, moisture, hygroscopicity, storage regimes, storehouse design, technical solutions for providing of the storage regimes; kinds of product conditioning: drying, active ventilation, hermetisation, storage in the absence of oxygen in carbon dioxide, nitrogen medium; conditioning equipment, energetic; conveyers and their selection criteria.
