Through
the use of fertilizer in agriculture is seasonal, it's production
especially in modern fertilizer plant, is essentially a continuous
process.
Most commercial fertilisers especially if there is a high concentration
of nutrients, are hygroscopic and have a high solubility in water.
When subjected to high humidity and varying atmospheric conditions
it leads to caking and loss in its properties and strength.
The fertilizer, when taken out of silos for bagging, is very hot and
thus, extremely hygroscopic. It is essential to control humidity levels
in the area during this period for free flow of fertilizer, through
auto-bagging machines into the polythene bag without lumping and caking.
Some high-speed, auto-bagging machines have a filling accuracy of
±10 gms weight per bag of fertilizer. High Humidity in the
bagging area causes this machine to break down frequently, leading
to loss in production and thereby profitability.
Another side effect of high humidity is that in contact with hydrocarbon,
the ammonium nitrate becomes explosive i.e. dangerous in nature. Hence,
it becomes very important that humidity be kept or held below 40%
Bry-Air Solution
To avoid moisture regain during bagging, it is necessary to condition
the air inside the bagging areas, so that the fertiliser does not
absorb moisture from the atmosphere.
Bry-Air Dehumidifiers maintain these conditions with ease regardless
of ambient temperature
Dehumidification is essential/ critical in the following areas
- The prilling tower - low humidity improves the prills
- Bulk Storage - to protect the prills etc.
- Bagging operations - for the ease in handling of prills etc.
