Hermetically sealed storage involves putting grain into sealed containers that stop the movement of air (oxygen) and moisture between the outside
atmosphere and the stored grain. The system can use special plastic
containers (such as the volcanic cube and grain cocoons) or smaller
containers made of plastic or steel or even clay water pots. The size of the
systems can range from 25 litres to 300 metric tons. The system can be used for paddy, milled rice and other cereal crops such as corn.
