DESCRIPTION § The Grain. Pro® Self Verifying Cocoon (S-VC) is a sealed flexible structure that is specifically designed to provide protection to dry agricultural commodities without the use of fumigants; § It is made from a specially designed flexible polyvinyl chloride (PVC) with an airtight zipper system; § It utilizes the principle of hermetic storage to prevent insect infestation during storage; § The S-VC has sealed structures that enable insects and other aerobic organisms in the commodity, or the commodity itself, to create a modified atmosphere by reducing the O 2 and increasing the CO 2 concentrations; and § The modification process often tries to lower the amount of O 2, moving it from 20. 9% to 0. 1%, in order to slow down the growth of aerobic organisms and the speed of oxidation reactions.
PROCEDURES 1 SITE SELECTION AND PREPARATION: Choose a flat, elevated site for installation. For indoor installation, clean the area to remove sharp objects. 2 FOR OUTDOOR INSTALLATION: Prepare a 5 -cm layer of fine sand (or equivalent) as ground foundation. 3 LAY-OUTING OF THE BOTTOM SECTION: Place one sack in every corner and stretch the bottom to prevent folds. Load the first layer of sacks in one direction.
4 REQUIRED STACK HEIGHT: Keep the sacks stable by loading the succeeding layers in a crisscross manner. Continue piling until the desired Cocoon height is reached. 5 BAGGED LOADING (MECHANICAL): Stacking of grains involves diverse operations such as conveyor, forklift. 6 TOP LAYER (OUTDOOR): Put an extra layer of bags to serve as a slope or peak of the stack.
7 PREPARING TO ZIP: Engaging the zipper pull using left and right keys. Continue zipping until starting flap is reached again. 8 COMPLETING THE ZIPPER PROCESS: In case of mal-alignment, pull the upper and lower sections of the liner walls in opposite directions. 9 ENGAGING THE TENSION STRAPS: The tension straps positioned along the wall of the upper section must be inserted through their respective buckles.
10 RAISING THE COCOON WITH TENSION STRAPS: The required tension can be achieved by attaching the cords to the buckles. 11 SETTING-UP THE GRAINSHADE: For outdoor installation, install poles and position the Grain. Shade™ at least 1 m above the Cocoon. 12 PRESSURE DECAY TESTING: A commercially available or improvised U-tube manometer can be used to monitor the pressure to ensure gastightness.
13 OXYGEN MONITORING: Using oxygen analyzer. 14 REPAIRING PUNCTURES AND OTHER DAMAGES: Punctures, cuts, and holes should be patched immediately. 15 CLEANING THE BOTTOM AND TOP SECTIONS: Maybe cleaned with soap and water, when dry, folded, rolled up and place them in the carrying bag.
