Grain bins are bulk storage structures for dry wheat, soybean, maize, oats, barley and more.
[1] Grain bins differ from farm silos which usually store foraged silage for animal feed and are made of concrete.
[3] The cold winter months are ideal for storing crops because of the low humidity levels, temperature, and pest problems.
Storing grain in the bins for more than six months into the spring and summer means they will have to be aerated more then to keep the temperature and humidity down.
Applying too much heat to the grain when attempting to lower moisture content can cause shrinkage which cuts into profits.
