Most often, the value of the grain (in dollars-per-tonne) is usually greater than the cost of the structure in which it is stored. Minor expenditure in improving the quality of the storage can thus be quickly recovered if commodity losses are commensurably reduced.
Compared to most other foodstuffs, such as meats and vegetables, grains are relatively easy to store. If grain is
kept insect-free and below
i
ts safe moisture content
, it will keep for many years with minimal loss of quality or nutritional value.
Whilst the choice of storage design is wide, the essential requirements needed to store grain safely remain the same.
These are:
Sealing
. The storage structure must keep the grain free from water ingress, insects, rodents and birds.
Cooling
. If grain is to be stored at moisture content above ‘safe’ levels, provision should be made for cooling the grain.
Easy disinfestation
. The storage facility should also permit easy and economical disinfestation of grain in the event of insect infestation.
And remember, a minor expenditure in improving the quality of the storage can be quickly recovered if commodity losses are commensurably reduced.
