For more than twenty years, the GrainPro Cocoon™ has proven itself as a viable and innovative solution for the long term storage of agricultural commodities worldwide. The Cocoon is originally designed for multiple indoor or outdoor use and is priced accordingly.
To meet the growing demands for affordable storage with a shorter useful life, GrainPro introduces the GrainPro Cocoon Indoor™ -- a low-cost Ultra Hermetic™ Cocoon for short-term indoor storage.
Made from lightweight materials, the patented Cocoon Indoor™ has all the gastight advantages of the Cocoon. It is designed for short-term use, but can be used again as long as the plastic material remains undamaged.
The GrainPro Cocoon Indoor™ acts like a large pouch. Commodities stored in boxes, bags or big bags are loaded through the top opening and sealed using the gastight zipper. Once sealed, oxygen (O2) is reduced thru insect respiration, while increasing carbon dioxide (CO2) levels to control the infestation, microflora and oxidation.
In some cases, speeding up the process of controlling infestation and oxidation is necessary. The GrainPro Cocoon Indoor™ uses the principles of modified atmosphere, and can also be used as a Gas-Hermetic Fumigation Self Verifying Cocoon™ (G-HF Self Verifying Cocoon™). It has a special inlet port to enable the flushing of liquid CO2, while excess air can be released through the zipper at the top.
Light, easy to handle and operate, the gastight features of the GrainPro Cocoon Indoor™ enable it to create and maintain a low oxygen/high CO2 environment for extended periods. This environment eliminates insects of all stages, while preventing the development of aflatoxin producing molds. Dry agricultural commodities can be stored long-term without the risk of moisture absorption and oxidation.
The GrainPro Cocoon Indoor™ can be customized with certain restrictions on its width and length. The perimeter of the Cocoon should be equal to a multiple of 10m (ex: 10m, 20m, 50m). No customization restrictions on height.
