热带牧草的干燥方式主要是自然晾晒和利用物理化学方法的耗能干燥，干燥技术落后，耗能大，营养损失较大，效率较低。针对热研2号柱花草设计研制出一种太阳能热带牧草干燥机，利用海南丰富的太阳能资源，采用3层网状输草装置和匀风控温系统，实现牧草均匀干燥加工。该干燥机试验时段平均工作温度为58℃，干燥室最高温度为67℃，太阳能集热器效率达到57．2％，牧草干燥效率为0．52t/d，干燥后湿基含水率≤17％。牧草营养成分与自然晒干相比总体保留较好，满足热带牧草干燥的生产要求。

The drying methods of tropical forage are mainly natural drying method and energy -consuming drying physico-chemical method .The drying technology is backward , which can lead to larger energy consumption, losing nutrient and lower efficiency .Based on stylosanthes cv .Reyan 2 design , a solar tropical forage drier can be invented .We can make full use of abundant solar energy in Hainan Province .Forage uniform drying can be achieved after using the three-layer mesh transmission apparatus of grass and air uniform temperature control system .The average operating temperature of this drier on the experiment is 58 centidegrade;the maximum temperature of the hothouse is 67 centidegrade;the efficiency of the solar collector reaches 57.2 percent;the efficiency of forage drying is 0.52 t/d, the wet basis moisture content af-ter drying is 17 percent or less .Compared with natural drying method ,the nutrient of forage dried by solar tropical forage drier can be generally better saved , which can meet the production need of tropical forage drying .
