PhilRice lowers rice storage losses with carbonized rice hulls
Researchers from the Philippine Rice Research Institute have developed a rice silo insulated with carbonated rice hulls to reduce storage losses and maintain the viability of rice seeds for a longer period.
The PhilRice team, led by Engr. Lex Tagudo, won an Industry and Energy Research competition held at the Don Mariano Marcos State University.
“We used carbonated rice hulls for its wide availability, low thermal conductivity, high moisture retention, and pathogen-free capability,” Taguda said.
The study found that the insulated silo can maintain an acceptable moisture content and germination rate of rice seeds for 10 months and seed vigor for seven months in outdoor conditions although an average of 186 weevils were recorded and 1.47 percent of the seeds were damaged.
The insulated silo was also designed to allow for easy loading and unloading of rice seeds.
