3. DESCRIPTION
The GrainPro® 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 O2 and increasing the CO2 concentrations; and
The modification process often tries to lower the amount of O2, moving it from 20.9% to 0.1%, in order to slow down the growth of aerobic organisms and the speed of oxidation reactions.

4. 1 2 3 PROCEDURES 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.

5. 4 5 6 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.

6. 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.

7. 10 11 12 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 GrainShade™ at least 1m 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.

8. 13 14 15 OXYGEN MONITORING: Using oxygen analyzer.
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.
