PREVENTING CONDENSATION
8.1. WHY DOES CONDENSATION OCCUR?
8.1.1. Condensation is caused by temperature difference i.e., hot weather by day and cool at night
or sudden rains in a hot sunny day. When air collides with a cool surface at dew point
temperature the water in the air condenses on the surface. Air movement inside the
Cocoon
TM
Lite follow the natural forces i.e., in convention currents hot air rise and cool air
sinks (except for the phenomenon called inversion). Hence, when warm air inside the
Cocoon
TM
Lite rise and hit the cool Cocoon
TM
Lite top cover at dew point temperature,
condensation reaction occurs, and water condenses.
8.1.2. Therefore, avoiding trapped warm air inside the Cocoon
TM
Lite can prevent condensation at
the top layer. This is the role of the GrainShade
TM
i.e., prevents heating up the air inside the
Cocoon
TM
Lite by repelling solar radiation. Condensation can be checked manually through
the inspection port. Close the inspection properly after checking.
8.2. MOISTURE CONTENT (MC) REQUIREMENT FOR SAFE STORAGE
8.2.1. Commodities should be dried before storage to at least 12% MC for sorghum, 9-10% millet,
12-14% for paddy, and maize, and 13% wheat.
8.2.2.
When the commodity is properly dried, there is virtually no “free water” that the
microorganisms can use to process the nutrients in the stored product for their growth and
development.
8.2.3. This condition can be maintained by avoiding ambient air (with variable moisture content) to
be in contact with the dried product using the hermetic storage technology.
8.3. SETTING-UP THE GRAINSHADE (OUTDOOR INSTALLATION)
8.3.1. Ensure that the poles are rigid and stable:
a. Use poles (pipe, lumber, or bamboo) at
least 1.5 meters away from each corner
and 1.0 meter higher than the Cocoon
TM
Lite.
b. Connect the corners of the GrainSahed to
apex of the poles, maintaining at least 1
meter clearance between the top surface
of the Cocoon
TM
Lite and the
GrainShade
TM
.
c. Additional wires to reinforce the pole by tying at the top with the other end pegged to
the ground away from the pole.
8.3.2. If poles are not feasible, tie the GrainShade
TM
to nearby posts, walls, tree branches, or pegs
for support.
8.3.3. To prevent from sagging and flapping during rain and strong wind, install a wire or rope
beneath and above the GrainShade
TM
.
