Title

RESISTANCE OF POTATOES TO AIRFLOW

Pages

  1-9

Abstract

 Knowledge of AIRFLOW RESISTANCE is an important consideration in designing an appropriate ventilation system and for proper fan selection. An AIRFLOW RESISTANCE device was designed and fabricated to measure the AIRFLOW RESISTANCE of potatoes. The device the composed of an air compressor, a Rota meter, a cylindrical bin to contain the potatoes and an inclined u-tube manometer, AIRFLOW RESISTANCE of potatoes was measured as a relationship between the airflow rate and pressure drop per unit depth (Pa/m) at 12 airflow rates of 0.085 to 0.55 m3 s-1 m-2. Two AIRFLOW RESISTANCE models, namely, Shedd’s and Hukill and Ives’, were fitted to measured data by using PROC NLIN of SAS. The effect of POTATO SIZE below 120 g (small), at or above 120g (large) and unsorted (mixed size), and BED DEPTHs of 25, 50, 75and 100 cm of potatoes on resistance to airflow was determined. Results showed that the AIRFLOW RESISTANCE of small size potatoes for a 100 cm BED DEPTH was 1.6 times higher than that for large size potatoes, and as the BED DEPTH of potatoes was increased, the AIRFLOW RESISTANCE was increased.
