1. INTRODUCTION
The GrainPro®Cocoon™ Lite comes to improve the performance, handling and cost of the
previous generation of PVC Cocoons. It is made of a light-weight yet uniquely developed sturdy
laminated PE material for ease in handling. It has an extremely low Oxygen Transmission Rate
(OTR) and low Water Vapor Transmission Rate (WVTR) to improve storage performance and
it’s optimal UV Protection to make the Cocoon™ Lite applicable for outdoor installation.
Standard sizes of the Cocoon™ Lite are from 5 Metric Tons to 20 Metric Tons capacities. It may
also be used for Carbon Dioxide Fumigation by introducing CO2 gas into the side Inlet Port and
discharging the Oxygen on top by an Outlet Port. For a more confident storing, Relative Humidity
can be visually checked thru it’s transparent plug RH indicator, also a gas-sampling port for
monitoring the Oxygen Level inside the Cocoon™ Lite using the GrainPro®Oxygen Analyzer.

5. INSTALLATION
5.1. SITE SELECTION
5.1.1. In selecting a site, look for:
a. Cocoon™ Lite is designed for both
indoor
and outdoor installations.
b. A smooth area away from standing or
running water.
c. Ensure that the site is protected from
stray animals and from theft.
d. Shade (otherwise under a
GrainShade™) to minimize temperature
differences.
5.1.2. Prepare the selected site by clearing away all sharp objects (stones, broken glass, nails,
etc.) that may puncture the Cocoon Lite™. Sufficient space to accommodate the Cocoon™
Lite and an inspection path around (at least 50 cm each side).
5.1.3. If ground will be used as flooring, put a
layer (5cm) of fine sand (or any
equivalent) on top of the soil as ground
foundation.
5.1.4. During loading, make sure that workers do not wear shoes with spikes that may damage the
Cocoon™ Lite. Preferably, choose a site that offers ease in loading/unloading, away from
crowded areas and rubbish. For indoor installation, clean the area to remove sharp objects.

5.2. LOADING
5.2.1. Check the moisture content of the
commodity to ensure the MC is at a safe
level.
5.2.2. Loading the bottom section:
a. Unfold the bottom section of the
Cocoon™ Lite and lay it out on the
prepared site.
b. Start piling the sacks on the bottom
section.
c. Put down the first four bags on every
corner of the Cocoon™ Lite (one for
each corner).
d. Make sure that the bottom section is
stretched by pulling the corners with
the bags. Stretching will reduce the
risk of rodent damage.
5.2.3. Required stack height:
a. Load the first layer of sacks in one
direction.
b. Continue adding layers in an inter
locking manner (criss-cross), i.e. one
layer on the top of the previous layer.
c. Stack sacks to the corresponding
heights.
5.2.4. Mechanical loading of bagged commodity, optional for big sizes of Cocoon™ Lite:
a. Stacking of grains involves diverse operations such as conveyor, forklift or crane.
b. Operations provide continuous stacking without delays especially for outdoor installation.
Conveyor
Forklift
Crane
5.2.5 The top layer:
a. Continue piling the sacks until the desired
Cocoon™ Lite height is reached.
b. Once you have reached the required
stacking height, provide one line of sacks in
the middle along the longitude of the stack.
c. This creates a crest that will keep rainwater
from accumulating on the top of the
Cocoon™ Lite.

5.3. POSITIONING THE TOP SECTION
5.3.1. There are several ways to place the top section:
a. By the rolling.
b. Using a mechanical aid (forklift and conveyor).
Rolling method
Use of forklift
Use of conveyor
5.3.2. Unfold the top section over the stack, and be sure that the top and bottom section arrows
meet and make sure the tension straps are on the outside.
5.3.3. Pull the sides all the way down over the stack.
5.3.4. Do not pull or carry the top section by the tension straps.
5.4. USE OF DESICCANT (CALCIUM CHLORIDE, CaCl2) - (RECOMMENDED))
Note: Desiccant (Calcium Chloride, CaCl2) is not included in the package.
5.4.1. Required dosage of Calcium Chloride, CalCl2.
5.4.2. Place the packed desiccant (Calcium Chloride, CaCl2), at the middle-top portion of the
bags inside the Cocoon™ Lite before Zipping.
5.4.3. If six (6) months of storage, spread-out the packed desiccant (Calcium Chloride, CaCl2) at
the top portion of the bags inside the Cocoon™ Lite before Zipping.

5.5.3. Using the zipper slider:
a. After engaging the zipper slider, pull
the zipper to start the zipping/closing
process.
b. To make zipping easier, a second
person should pull the top and bottom
liners’ zipper tracks close to each other
which will serve as guide while the
zipper pull advances.
