The relevance of the study to establish methods of storing corn grain is related to the problem that exists in the technology of storage of crops of different crops. Methods and material and technical base with preservation do not fully take into account the characteristics of individual crops as objects of storage, which leads to loss of products and deterioration of its quality. There is also no technical and technological assessment of new methods of storage and granaries, including metal type. The article presents the results of research, which revealed the peculiarities of storage of corn grain in metal granaries. The temperature regime, which is formed in different places of the embankment and grain quality indicators - humidity, purity, acidity, viability (germination) depending on the thermal protection of the storage are established. Layers of grain embankment were found in the warehouse, where unfavorable conditions for preservation and stable condition of products are created. The technical and technological assessment was carried out and the efficiency of different granaries was determined depending on the storage and the direction of its use. As a result of the conducted researches the technical and technologicalcharacteristic of various ways applied to storage of grain is made, their advantages and lacks are established. For the purpose of safe storage in metal granaries it is recommended to carry out their thermal protection by drawing heat-insulating material on external walls of storage. For long-term storage of corn grain stocks, its humidity should not exceed 12% with the removal of the total mass of the unstable fraction. In the long run, it is necessary to reduce the storage of grain in a controlled gaseous environment, as one that increases a high degree of preservation of products and their quality.
