Design of the solar drying greenhouse and drying equipment for the QinghaiTibet Plateau

In order to dry fresh forage with low cost in QinghaiTibet Plateau, a scheme is presented which utilizes solar energy to work in this study. In the scheme, air is firstly heated by a solar collector, and then the hot air enters a hot greenhouse to dry the forage. The forage can be further dried by a rotary dryer. The cost of the scheme for drying is expected to be reduced remarkably since a little of regular energy is needed, so it is suitable for drying forage in QinghaiTibet Plateau.
