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.
