4. Discussion
In this study we evaluated the impact of using eolic exhausters
in metal silos as a complement to conventional aeration during
paddy rice storage on energy consumption, head rice yield, percentage
of stained kernels, rice whiteness, cooking time, hardness,
and as well as pasting and thermal properties of rice flour.
The head rice yield during 9 months storage was greater in
grains stored in silos equipped with exhausters. The increase and
subsequent decrease of the HRY during storage without the
exhauster system was reported by Daniels et al. (1998). This phenomenon
can be attributed to the time during which the grains
remain at a warmer ambient temperature. The smaller decrease in
the HRY observed in grains that were stored using exhausters can
be linked to the more uniform and lower temperature inside such
silos, as described by Wongpornchai et al. (2004), indicating that
the use of exhausters can reduce the HRY loss from the sixth to the
ninth month.
