| Abstract | ||||
| Wheat production and storage have become one of the most important issues facing Egypt at present and in the future due to the lack of suitable storage structures, which leads to large losses in food grains. The study was conducted to investigate the changes that may occur in some physical and mechanical properties of wheat grain during storage for 12 months in different vertical cylindrical silos with identical dimensions and sizes. Silos materials were Fiberglass, (FG), Plastic (PE), and galvanized steel (GS) and they were provided with mechanical aeration Strategy. Physical characteristics included grain moisture content, linear dimensions, geometric mean diameter, arithmetic mean diameter, volume, calculated surface area, spherisity, weight of one thousand grains, particle, bulk density and porosity. Mechanical properties included angle of repose, static shear stress, hardness and coefficient of static friction against three structural surfaces (plywood, galvanized iron, and rubber). Samples were analyzed before storage and after every 2 months during the storage period. Results showed that grain's moisture contents followed a fluctuating course for 360 days depending on the different storage methods. length (L), width (W), thickness (T) were influenced by the variation in the grain moisture content during the storage period. Geometric properties Arithmetic means diameter (Da), geometric mean diameter (Dg), sphericity (φ), grain surface area (Sa), and grain volume (V) have shown parallel changes to L, W, and T values. there was diversity in hardness, shear stress, angle of repose and the coefficient of friction on all surface (plywood, galvanized iron, and rubber) of stored grain this variation related to moisture variations during storage periods | ||||
