GrainPro Cocoons™

GrainPro Cocoons™ are airtight (hermetic), unsupported rectangular structures made of lightweight UV resistant PVC. The simple two-piece Cocoon consists of a top cover and bottom floor piece joined together with a PVC tongue-&-groove zipper similar to those used to close environmental safety suits. Insects trapped in the bagged grain expire in a matter of days as a result of an increase in carbon dioxide and reduction of oxygen. Cocoons are packed folded in a carry bag for transport and can be made ready for use in minutes.

Cocoons are designed to store bagged commodities such as:

  • grains and flour
  • seeds and pulses
  • cacao and coffee beans (in modified or regular atmospheres)
  • other dry agricultural products

    • Cocoon capacity based on wheat: 5 Tonne, 10 Tonne, 20 Tonne, 50 Tonne, 100 Tonne,
    150 Tonne, 300 Tonne sizes, and MegaCocoon 1050 Tonnes
