青藏高原牧草太阳能烘干温室及干燥装置的设计

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

为了低成本的干燥新鲜牧草,本研究设计了以青藏高原丰富的太阳能资源为干燥能源的牧草烘干温室及干燥装置。该装置用太阳能空气集热器加热空气,热空气进入高温温室,对牧草进行加热干燥。将它与小型滚筒式牧草干燥机相结合,可提高工作效率,节约常规能耗,显著地降低牧草干燥成本,有效解决青藏高原新鲜牧草的干燥问题。

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.
