In recent years, with the promotion of mechanization of agricultural operations, grain dryers play an important role. In the case of rice, if there is no good weather after harvesting, and the drying is not sufficient, the germination and mildew may occur. Grain dryers greatly facilitate agricultural production activities and, to a certain extent, enhance farmers' benefits. Therefore, Ruian City continued to increase subsidies for grain dryers, and guided local governments to rely on large grain farmers and farmers' professional cooperatives to promote the construction of drying centers and play a demonstration role. After the introduction of drying equipment by large grain growers, the rice will no longer rot. In the rainy season, the grain can be dried for other large grain growers, and processing fees will be charged. Enterprises and cooperatives will be able to acquire wet rice when they introduce drying equipment, which will save the company's expenses.
