Raisin is popular dry fruit item with long life around 6 months if stored properly. Apart from use as a dry fruit item, it is used in large quantities in many sweet preparations, some bakery product items and desserts. Raisins are also used in some herbal medicine preparation. Harvesting of grapes start from January and ends by may every year. Hence this business is seasonal and factories work for 6 months every year.

It requires sun rays which is dependent on time and season as well as it changes with day time. In rainy season it is very difficult to dry the raisin because of lack of sun rays and procedure adopted for this very sophisticated.
