1. Fumina Tanaka, Tanaka Fumihiko, Ai Tanaka, Toshitaka Uchino, Mathematical modelling of thin-layer drying according to particle size distribution in crushed feed rice, Biosystems Engineering, 10.1016/j.biosystemseng.2015.05.007, 136, 87-91, 2015.08, A thin-layer drying model taking into account the particle size distribution of crushed feed rice was developed to simulate moisture content during high-temperature drying. The model was based on the Page equation, which was regarded as a suitable empirical equation to describe the thin-layer drying of rice. The proposed model, with an assumed a Rosin-Rammler distribution, successfully predicted the mean moisture content of rice during drying experiments with a mean error of 0.5% dry basis at 60, 70, and 80°C. In order to investigate the effect of particle size distribution of rice on the drying process, a stochastic model based on Monte Carlo simulations was developed. The model developed here could provide useful information on the drying behaviour of rice particles, individually and collectively, in a thin layer bed. It was clear that uniform drying could be achieved by increasing the drying temperature..

Fumina Tanaka, Tanaka Fumihiko, Kotaro Yamashita, Ai Tanaka, Daisuke Hamanaka, Toshitaka Uchino, High temperature drying characteristics of crushed rice for animal feed, Engineering in Agriculture, Environment and Food, 10.1016/j.eaef.2014.05.002, 7, 3, 133-138, 2014.01, Thin-layer drying experiments of rough, brown and crushed rice for animal feed were conducted to determine drying characteristics. Since optimization of the drying process reduces cost, we also investigated the conditions for improving the efficiency of rice drying. Rice samples were dried at 40-80 °C with 10%RH. The results showed that 1) the time required for drying crushed rice was shorter than for rough and brown rice, 2) the Page equation was a suitable model to explain the drying characteristics of crushed rice, 3) the drying constant of crushed rice showed the highest value and had Arrhenius-type temperature dependence, 4) the optimum drying temperature of crushed rice was 80°C..
