Definition of silos for grain storage The grain silos are constructions designed to store bulk products such as seeds, feed, fertilizer or other granular products in the absence of moisture. This idea of collecting grains and seeds dates back to at least, 8th century BC from which archaeological remains of ancient Greece are found that attest to it. In ancient Rome, there were underground silos with hardened clay coatings to obtain better preservation of the products that were stored in them. The first silos that are known from the modern era were built in wood with zinc, straw or tile roof. The silos for grains are elevated on the ground located on piles or posts either of concrete or wood so that some animals do not eat the stored grain contained. The shape or dimension of grain silos vary according to the needs of the industries and can be rectangular, square or cylindrical. The grain silos are located in areas away from walls and trees to prevent insects and rodents
SILOS It is obtained from a Greek word – silos which means ‘’pit for holding grain’’. Silo is used to store materials in huge amount such as grains, cement, coal, carbon black,etc. Since different industries use silos for different purposes hence many different conditions need to be undertaken while deploying them and get the most out of them. Mostly stored items are either solid or in powder forms. CONSTRUCTION Generally, one can easily find cylindrical shaped silos with a metal support although there exists rectangular and square ones also. They can be built with a metal, stainless steel, reinforced concrete, wood, reinforced plastic, etc. The interior of silos is generally smooth and has a special coating inside. Also. During construction of a silo, the amount of product to be stored in it, location, weather conditions as environmental factors such as temperature, humidity are also taken into account. CLASSIFICATION Depending on the raw material to be stored 1.
