Moisture Transfer in Blended Long-grain Rough Rice
نویسندگان
چکیده
Moisture transfer in mixtures of lowand high-moisture content (MC) rough rice (ranging from 9.5 to 18.0% w.b.) was investigated with a single-kernel moisture tester over a period of30 days. The intergranular air attained constant relative humidity corresponding to the mean MC of the mixture within afew minutes ofmixing. About 90% ofthe change in the MC of lowand high-MC kernels occurred within first one or two days of mixing even though moisture exchange continued over a period of30 days. Changes in standard deviation (SD) ofMC of the mixture with time, when normalized as a SD ratio, were similar to simulated changes in MCs of lowand high-MC fractions relative to their mean Me. The developed relationships can be used to estimate the MC variation with time in lowand high-MC fractions of mixed rough rice.

Development and Validation of Mass Transfer Model for rough Rice (Sepidrod) Kernel drying
Rapid drying can increase brittleness and induce internal cracks which predispose the product to breakage during subsequent activities. The drying process must be understood and controlled so that design guidelines which reduce or minimize drying damage to rough rice can be established and improved. This study is to give a mathematical model with numerical solution to follow the mass distributi...
متن کاملExperimental and Theoretical Investigation of Moisture Dynamics in Intermittent Drying of Rough Rice
Intermittent drying is a satisfactory technique for drying of heat sensitive grains especially rough rice. This method consists of two separate stages applied intermittently: drying and tempering. In this work, intermittent drying of rough rice is investigated both theoretically and experimentally. In order to characterize this process; a multi-scale model consisting of macroscopic and microsco...

THE effect of moisture content, fine material con centration and bulk density on the airflow resistance of long-grain rough rice was determined. Airflow resistance was measured at air velocities ranging from 0.013 to 0.387 mis, bulk densities from 480 to 604 kg/m3, fines concentrations from 0 to 30% and moisture contents from 12 to 24 %. Airflow resistance was accurately described by an empiri...
