A SIMPLE METHOD FOR THE SEPARATION OF STONES FROM CORIANDER SEEDS BASED ON THE USE OF FLUIDIZATION TECHNIQUE

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.
