The Thermal Dynamical Properties and Mathematical Simulation Analysis Studied by Dynamic Mechanical Analysis
The thermal dynamical properties and mathematical simulation analysis of rice seeds were studied by dynamic mechanical analysis (DMA). A long grain hybrid rice variety (Jinyou 974) grown in Hunan province of China was used in this investigation. The results snowed that the thermal transition was observed obviously by the peak temperature of tan delta curves. The glass transition temperature increased from 58.87±2.76℃to 80.19±1.62℃with decrease in moisture content from 23.8±0.7％ to 11.2±0.3％. Through detailed analysis of the tan delta peak value of rice seeds, the values of both storage modulus and loss modulus were significantly different while the significant differences among the values of tan delta only appeared for the rice seeds with very low moisture contents, or with significantly different moisture contents.
