摘　　要：开放式热风干燥(AD)工艺以其设备成本低、操作和维修简单等特点,在国内大批量脱水蔬菜生产中仍占有较高的比例。但开放式AD蔬菜的能耗高,故对其进行节能技术研究是项急需而有意义的。我们可以从AD工艺前处理、AD和其它干燥方法联合、干燥系统改进、余热回收以及工艺参数再优化等5个方面来降低AD蔬菜生产中的能耗。In Open-Type Air Drying（AD） process, the equipment is cheap and its operation and management are easy, so it is still widely used in domestic vegetables drying industry. But it takes a high proportion of energy consumption. Studies on energy conservation are needed （1）drying methods, （2）optimization of the and important. The energy conservation can be reduced in following aspects, process, （3）dryer＇s improving, （4）waste-air recycling and （5）application of regenerative energy.
