Post Harvesting

Post Harvesting 

Storage: 
Combining is usually done when seed moisture content is less than 15 per cent. Ten per cent moisture is considered dry, but buyers prefer nine per cent. Cylinder/rotor speeds should be set at approximately 500 rpm under dry conditions. An initial setting of 0.5 inches (20 mm) at the front and 0.25 inches (10 mm) at the back is suggested. Wind speed should be reduced to the minimum, and ground speed should be slowed. Coriander oil is very volatile, so the seed must be dried gently; avoid hot air drying. Aeration is useful for reducing moisture content; however, coriander seed readily takes up other odors, so store away from gasoline, herbicides, etc. Remove green material such as weed seeds as quickly as possible, since aeration will be diverted around these areas in the storage bin, resulting in the potential for spoilage. After drying, seeds are separated by light beating with sticks and winnowing.
