I have been drying the spices for my business in the open sun but they took a lot of time to dry, and also the color used to get fade. But as I have purchased the solar dryer my spices are getting dried in less than 3 days without any loss to the color and fragrance. After purchasing of the dryer my business has boosted up a lot. Thank you Raheja Solar!
