Check for leakage, and do repairs. If the cause is not found, consult GrainPro’s
Technical Support Department immediately at [email protected].

DISMANTLING
5.9.1.
The commodity will only be unloaded
at the end of storage
.

PREVENTING CONDENSATION
6.1.
WHY DOES CONDENSATION OCCUR?
6.1.1.
Condensation is caused by temperature changes 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 vapor in the air condenses on the surface. Air movement
inside the GS Bag-1.0/GHF follow the natural forces i.e. in convection currents hot air
rise and cool air sinks (except for the phenomenon called inversion). Hence, when
warm air inside the GS Bag-1.0/GHF rises and hits the cool GS Bag-1.0/GHF top cover
at dew point temperature, condensation occurs.
6.1.2.
Therefore, avoiding trapped warm air inside the GS Bag-1.0/GHF can prevent
condensation at the top layer. This is the role of the roof cone (shade/cover). It
prevents heating of air inside the GS Bag-1.0/GHF by repelling solar radiation.
6.2.
MOISTURE CONTENT (MC) REQUIREMENT FOR SAFE STORAGE
6.2.1.
Commodities should be dried before storage to at least 12% MC for sorghum, 9-10%
millet, 12-14% for paddy and maize, and 13% for wheat.
6.2.2.
When the commodity is properly dried, there is virtually
no “available water”
that the
microorganisms can use for growth and development.
6.2.3.
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.
