Equipped of drying equipment should not be too small, because in the case of meeting the rainy season in harvest season. It needs to dry by the drying equipment, the amount is larger, small productivity is useless.



State and local repository, centralized grain production areas should use large, medium-sized drying equipment. The service radius of stationary grain drying equipment should be smaller than bigger, to reduce the transport distance, reduce cost and improve efficiency. Mobile grain dryer can be used to focus on rural areas and southern small grain-producing areas. The productivity of generally 2 ~ 5t / h is appropriate. Too small is not welcomed, the best choose is a machine multi-purpose. Not only applies to drying grain and grain seeds, but also applies to a number of economic crops. The service radius should be bigger in order to play the role of mobile dryer.
