Abstract:

In this study, determination of minimum fluidisation velocity of rice, effects of temperature on drying rate and puffing quality of pre-conditioned rice were investigated. The experiments were conducted on two varieties of rice namely parboiled Polished rice namely medium and long. The drying behaviour in a fluidised bed was studied at three different temperatures of 50, 60 and 700C and the air velocity 3.6 m/s. Moisture reduced exponentially with time and dependent upon drying temperature. Minimum fluidisation velocity at 10 and 30% (wb) moisture content is 0.95 and 0.87 m/s respectively. Puffing characteristics like Expansion ratio and % puffing of low amylose content of rice was greater than more amylose content of rice. It was noticed that expansion of rice during puffing correlated strongly with amylose content.
