Rice parboiling using a dual-powered parboiler: Evaluation of energy consumption patterns and milling quality
Energy plays an important role in rice processing whereby the amount of energy consumed could influence the cost of production. Therefore, this study aimed to evaluate the energy consumption and milling quality of three rice varieties (FARO 15, FARO 60 and FARO 62) using a dual-powered rice...

Summary: | Energy plays an important role in rice processing whereby the amount of
energy consumed could influence the cost of production. Therefore, this
study aimed to evaluate the energy consumption and milling quality of three
rice varieties (FARO 15, FARO 60 and FARO 62) using a dual-powered rice
parboiler. The energy consumption patterns viz steeping energy consumption,
steaming energy consumption, total energy consumption and energy intensity
of the rice varieties using electricity and Liquefied Petroleum Gas (LPG)
combustion as the power source of the parboiler were determined using
standard equations. The milling quality in terms of milling recovery and
head milled rice were also determined using standard procedures. The energy
consumption during steeping and steaming ranged from 39.02 MJ to 40.00 MJ
and 12.90 MJ to 14.09 MJ, respectively. The total energy consumption and
energy intensity ranged from 31.62 MJ to 32.01 MJ and 7.90 MJ/kg to 8.00
MJ/kg, respectively. The milling recovery and the head milled rice of the
rice varieties ranged from 64.23% to 66.76%, and 55.45% to 59.18%,
respectively. The total energy consumption and energy intensity of the rice
varieties differ based on the power source of the rice parboiler. The power
source also influenced the milling recovery and head milled rice of the rice
varieties. The use of gas as a power source for the rice parboiler consumed
more energy than electricity. The information provided in this study would
guide energy conservation, prevention of production downtime and improving
rice milling quality. |
