IRRI Super Bag
The IRRI Super Bag makes the principle of hermetic storage available to farmers and processors at low cost. The IRRI Super Bag is a farmer-friendly storage bag that allows cereal grains and other crops (e.g., maize or coffee) to be safely stored for extended periods. The Super Bag fits as a liner inside existing storage bags (e.g., woven polypropylene or jute bags).
Why is a Super Bag important and how does it work?
Relative to traditional storage systems, Super Bags have the following benefits:
Super bags reduce the flow of both oxygen and water between the stored grain or seed and the outside atmosphere. When properly sealed, respiration of grain and insects inside the bag reduce oxygen levels from 21% to 5%. This reduction reduces insects to less than 1 insect/kg of grain without using insecticides - often within 10 days of sealing.
The stability of controlled grain moisture inside the bag prevents wetting or drying of grain. This stability reduces the degree of grain cracking and so head rice recoveries are higher upon milling.
The super bag is currently designed to store up to around 50 kg of grain or seed. (Other similar systems can store large quantities of grain).
