Below 9% moisture content, grains can be stored safely for more than one year, but it may result in loss of germination. A corn silo made from corrugated sheet was the subject of a complete structural failure during standard operation. When the grains are at 14% to 18% moisture level, the storage period is reduced to only 4-8 weeks due to problems of mould growth resulting in discoloration of grains. As a rule of thumb 9% to 13%, moisture content of grains may give a storage life of 8-11 months, however, there still may be some infestation problems, which have to be tackled with effective fumigation. Developed through experiments in the 1800s, silage is essentially a foliage cropperhaps an entire corn stalk, perhaps an entire alfalfa plant, perhaps something elsethat has been finely chopped and then stored while the moisture content is still high, somewhere near 60 percent. We have a wide variety of bulk bin sizes for you to choose from. The storage period of grains depends upon the moisture content of grains. Our hopper bottom feed storage bins silos are made in the USA from high quality galvanized steel and provide the perfect storage for your feed or any dry free flowing material, such as seeds, grain, corn, dried beans, and more. In general, relative humidity of 65% or less is considered safe for the storage of grains. For best results, chop corn and sorghum silage at 1/4 inch and hay silage at 3/8 inch theoretical length of cut. Silo Management Bunker silo management begins at harvest. Not only could you suffocate from being buried in the corn/grain, but both release fumes that will kill you. Grain storage facilities ensure that harvested goods will preserve the highest quality and allow you to. Silos full of corn or grain are extremely dangerous. Table 2 gives approximate bunker silo capacities for alfalfa, corn and sorghum silage. Silos are the best way to add value to your grain. Understanding the EMC concept of grains is very important to understand how grains will behave in various temperature and relative humidity conditions. Although the first cost of a concrete or steel silo for grain storage is usually somewhat higher than the cost for a comparable volume round metal bin storage. a common wall height for all silos helps make multiple silo design more manageable. This EMC value is different for different grains based on RH and the Temperature of the surrounding air. This final moisture content of the grain is called Equilibrium Moisture Content (EMC). Grains absorb or desorb moisture based on temperature and relative humidity of air surrounding them and continue to absorb or desorb moisture until it attains equilibrium with the surrounding air.
