Sample Location Effects
Table 3 gives the apparent moisture content determinations of whole-grain rough rice samples made at different locations on the two shelves after drying for 4 and 20 h in an oven set at 130°C. The standard deviation of moisture content on both the upper and lower shelves for each drying time was less than 0.1 % w.b. However, individual moisture contents showed a deviation from the associated shelf/drying period mean of up to 0.24% w.b. It was observed that an increase in the drying time from 4 to 20 h resulted in lower standard deviations in mean moisture contents.
