Pp. Thomas et al., A SIMPLE METHOD FOR THE SEPARATION OF STONES FROM CORIANDER SEEDS BASED ON THE USE OF FLUIDIZATION TECHNIQUE, Journal of Food Science and Technology, 30(4), 1993, pp. 303-305
Coriander seeds available from the market invariably contain about 5%
stone particles. These, in turn, increase the ash content of the coria
nder powder and can damage the grinder, if not removed. A simple metho
d has been developed for the removal of stones from coriander seeds. I
t works on the principle of minimum fluidization velocity differences
of stones and coriander seeds, when the mixture is subjected to fluidi
zation.
