Resumen:
The National Institute of Agricultural
Technologies of Argentina
(INTA) developed a new software, named AireAr, for sizing and selecting grain
aeration fans. AireAr can be used for selecting aeration fans for corn, wheat,
soybean, sunflower, canola, barley, oats and sorghum. The user can select two
different storage structures, round bin or flat storage, and enter its
dimensions as well as the grain depth. The user can also chose between flat
bottom or conned bottom, and between leveled grain surface or grain peak. Based
on this information the software computes the total grain volume and grain
depth. AireAr takes into account the grain moisture content in order to adjust
grain density. The user enters the desired specific airflow (0,1 m3min-1t-1
for maintenance aeration, 0,3-0,5 m3min-1t-1
for wet grain aeration and 1-2 m3min-1t-1 for
in-bin drying) and the software computes the total airflow (m3min-1),
the air resistance due to the grain using the Shedd´s equation (the resistance
of the airflow distribution system is also considered), and the fan power. The
user can select from a database a suitable commercial fan that would met the
requirements predicted by the software (fan power, total resistance and total
airflow). The fans are ordered in the database by power, type (axial or
centrifugal) and manufacturer. Once a candidate fan is selected, the user can
compare the performance of the selected fan (airflow-static pressure curve provided
by the manufacturer) with the requirement of the system estimated by the
software for different depths. The software provides charts and tables with the
performance of the selected fan if it were installed in the user´s bin, so the
user can compare the desired airflow rate with the airflow rate obtained with
the selected fan for different grain depths. If the selected fan does not
satisfy the desired airflow requirement, the user can select another fan from
the database, or add a second fan in parallel or in series configuration. The
user can select between Spanish or English language, and International or
British unit system. The software is available on-line (http://online.inta.gov.ar:8080/aireAr/login.jsp),
and registration and use is for free.
