 Seed Drying
Placed the washed seeds in fine-mesh bags. Excess water can be removed by hanging the seeds in the shade for a day.

spin-drying seeds
An even quicker way to remove excess water from seeds is to spin them in a washing machine. Use the spin-cycle of a clothes washing machine (don't wash the seeds, only spin dry them). 

loosening clumps
After the excess water is removed, uniformly spread the partially dried seeds in a flat plastic container or aluminum pan. Loosen any clumps of seeds. Enclose this container with its seeds into a net nylon bag.

placing seeds in seed dryer
Place the container in a seed dryer. Drying continues for 3-4 days, maintaining a temperature of 28-30ºC. Higher temperatures at the time of drying may cause seeds to germinate.

Stir the seeds 2-3 times daily so that seeds dry uniformly. Loosen any seeds that clump together. These procedures will get the seeds to the desired 6-8% moisture content.
