Effects of Oven Drying Temperature and Drying Time on Rough Rice Moisture Content Determination
نویسندگان
چکیده
T HE effects of oven drying temperature and drying time on whole-kernel, long-grain rough rice moisture content determination were investigated for different moisture content levels ranging from approximately 9 to 22% (w.b.). The results showed that a simplified oven method can be used for rapid moisture measurement with accuracy comparable to that of a standard Association of Official Analytical Chemists (AOAC) method. An equation was developed that relates the apparent moisture content determined using a given drying time and temperature to the moisture content determined by the standard AOAC method.

Experimental 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 use of low air temperatures (79 to 93 °F) and relative humidities (19% to 68%) to dry thin-layer samples of rough rice to the desired 12.5% moisture content was investigated. Drying rates and durations and their effects on the quality parameters of head rice yield, color, and pasting viscosity of longand medium-grain rice cultivars harvested at 19.6% and 17.5% moisture contents, respectivel...

متن کاملKernel Moisture Content Variation in Equilibrated Rice Samples
An individual kernel moisture meter and an individual kernel oven drying procedure were used to quantify the kernel-to-kernel moisture content (MC) variation in equilibrated rough rice samples varying in MC from 9 to 37%, w.b. Average, bulk sample MCs were also determined using an oven drying method. No difference (p < 0.05) was found in the average MCs measured by the meter at three weeks or t...
