Rice is best stored as paddy because the husk provides some protection against insects and prevent grain quality deterioration. A safe or hermetic storage system prevents the grain from getting wet after drying and also gives protection from insects, rodents, and birds.
Rice can be stored for longer periods if:
- Moisture content is maintained at less than 14% for grain and 12% for seed;
- Grain is protected from insects, rodents, and birds; and
- Grain is protected from re-entering of moisture by rain or from the surrounding air.
A rule of thumb for seed is that the life of the seed is halved for every 1% increase in moisture content or a 5°C increase in storage temperature above recommended levels.
Rice storage systems
Bag storage system
- Bags should not be stacked higher than 4 meters.
- Bags should be stacked under a roof, in a shed or under water-proof tarpaulins.
- A one-meter gap should be kept between and around stacks.
- Bags should be stacked on pallets above ground.
- Bags should be stacked so that fumigation can be undertaken, if necessary.
Hermetic or sealed storage
