Effects of Discharge Fan on the Drying Efficiency in Flat-bed type Dryer
— The study of interaction among the grain, moisture, and the surrounding space (air) is key to understanding the grain-drying process. In Iran, rice (mostly Indica type) is dried by flat bed type dryer until the final MC reaches to 6 to 8%. The experiments were conducted to examine the effect of application of discharge fan with different heights of paddy on the drying efficiency. Experiments were designed based on two different configurations of the drying methods; with and without discharge fan with three different heights of paddy including; 5, 10, and 15 cm. The humid heated air will be going out immediately by the suction of discharge fan. The drying time is established upon the average final MC to achieve about 8%. To save energy and reduce the drying time, the distribution of temperature between layers should be fast and uniform with minimum difference; otherwise the difference of MC gradient between layers will be high and will induce grain breakage. The difference of final MC between layers in the two methods was 48-73%. The steady state of temperature between the two methods has saved time in the range of 10-20%, and the efficiency of temperature distribution increased 17-26% by the use of discharge fan.
Moisture Adsorption in Cereal Grain Technology – A Review With Emphasis on Rice
Effects of moisture adsorption on low-moisture rice were recognized as early as 1930. However, as rice production became mechanized, research emphasis changed to drying. Effects of moisture adsorption by low-moisture wheat grains were also observed. For the last 25 years, the moisture adsorption phenomenon has been gaining recognition and is rapidly becoming an area of primary research in post harvest rice technology.
