Sustainable Solutions:
Hermetic Storage Systems
Hermetic storage systems preserve quality and allow the storage
of grains and commodities without the use of pesticide or
fumigants. The hermetic air-tight and water-tight food-grade PVC
Cocoons™ prevent moisture gain or loss and prevent the formation
of molds. Insects that infest grains are eliminated as insect
respiration within the Cocoon™ produces levels of carbon dioxide
that are lethal to insect pests.
MDI has researched the application of hermetic storage and
transport for coffee and cocoa in collaboration with industry
and research partners. Coffee stored under hermetic conditions
will not gain or lose moisture content even during long-term
storage in tropical regions (country of origin). This is
critical in maintaining quality and flavor, and in preventing
mold and associated ochratoxins that can pose a health risk to
consumers.
GrainPro
Inc manufactures and distributes
portable hermetic storage Cocoons™ for grains and commodities
stored in sacks and available in sizes from 5 MT to 150 MT. The
Cocoons™ allow for diversification for producer organizations to
provide new storage businesses without incurring infrastructure
costs associated with conventional storage methods.
For coffee in transport, hermetic liners called SuperGrainbags™
are available. Café Solar®, coffee dried using renewable energy
technology is shipped in SuperGrainbags™ to ensure quality
preservation during storage and transport. The patented hermetic
storage Cocoons™ can operate outdoors with a light-weight
reflective mesh to prevent heating from direct sunlight, which
can cause moisture migration due to differential heating.
Benefits of Hermetic Storage Systems
Hermetic storage systems are a well-proven technology with many
benefits to producers, exporters, and importers.
Hermetic Cocoons™ eliminate the need for
pesticide and fumigants for the storage of staple grains, such
as, rice, corn, beans, paddy, milled rice, and other cereal
crops.
Hermetic storage preserves quality and flavor.
Seed viability is greatly extended with hermetic storage.
Hermetic storage prevents moisture loss or gain even in
tropical climates.
Hermetic Cocoons™ provide a low cost opportunity
for producer organizations to diversify and offer storage
services as a new business.
