A silo (from Ancient Greek σιρός (sirós) 'pit for holding grain') is a structure for storing bulk materials. Silos are commonly used for bulk storage of grain, coal, cement, carbon black, woodchips, food products and sawdust. Three types of silos are in widespread use today: tower silos, bunker silos, and bag silos.
Once the grain is sufficiently dry it can be transferred to a granary for storage. Today, this can be done using a mechanical grain auger to move grain from one granary to another. In modern silos, grain is typically force-aerated in situ or circulated through external grain drying equipment.

Grain loss can be caused by mold growth, bugs, birds, or any other contamination. One method of preventing loss is hermetic grain storage. Hermetic grain storage strives to eliminate all exchange of gases within the storage system. This mitigates bacterial activity and prevents rodents and bugs from being able to breathe inside the storage ...
