Efficiency of the gravity table in the processing of coriander seeds
ABSTRACT This study aimed at assessing the quality of the physiology and health of the coriander seeds processed in a gravity table. This was investigated at two settings namely, I with angle X 3.5° and angle Y 3.1° and II with 3.9° and 2.7° angles, with five gravity table discharges (high, high intermediate, intermediate, low intermediate and low) besides feeding. The experiment adopted the 2x6 factorial scheme, in a completely randomized design, with four replications. Two coriander seed batches of cultivar Verdão were used. The gravity table was adjusted to have 2.9 m s-1 air speed on the platform. The seed fractions discharged in the lower portion of the gravity table revealed poorer physiological performance than that of the others. Regulation I (angle X 3.5° and Y 3.1°) was sufficient for the coriander seeds to be processed in batch 1 and regulation II (angle X 3.9° Y and 2.7°), was adequate for batch 2. The processing of batch 1 in regulation II was effective in separating seeds of higher sanitary quality by rejecting the contaminated ones.
