EVALUATION OF THE EFFECT OF THE AIR GAP SIZE TO THE AIR DISTRIBUTION IN CHAMBER DRYING EQUIPMENT VIA CFD METHOD

Abstract

This study evaluates the effect of the air gap size (d) on the air uniformity in the chamber
dryer with the most appropriate air blade angle value inherited from the previous study.
Several case studies with different values of “d” are tested. The most appropriate ratio value
is 1/2; when criterion values reach the best values, show a significant improvement in the air
received by the trays and the air uniformity in the equipment. Furthermore, several cases of
tray and equipment length are also tested, and they also affect the air distribution.
