Most overflow separators are installed in the wrong place.
When the gin is ginning wet cotton the overflow feeds wet cotton into the conveyor
distributor, this just killed the gins drying system.
All of the gins the overflow separator is feeding have trouble ginning because the
cotton they are getting is cold and wet. All of the gins the overflow separator is not
feeding are ginning fine.
After wet cotton sits in the overflow pen or automatic overflow control for a few
minutes, it gets cold and hits dew point, which causes it to collect water on the
surface of the cotton. Then when you pick up this cotton with cold moist air it gets
colder yet and picks up more moisture out of the cold moist air that is handling the
cotton. This wet cotton is then fed into the conveyor distributor where it mixes with
the cotton you have dried in your overhead and this mixing undoes what your drying
system did to dry the cotton. Now all of the cotton so mixed is cold and wet.
This action kills the drying that the overhead did and wastes the money the gas cost
to dry the cotton in the first place. The ginner then turns the heat up, burning more
gas and costing more money.
If the overflow separator is over the module feeder belt or feeding back into the No. 1
drying system, none of the above happens. The ginner can run a more even heat
and possibly a lower heat, saving the gin money with the overflow separator in this
position. The gin plant will produce more uniform grades and usually better grades.
The gin stands and the plant are easier to run with more bales per day ginned will
result.
