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据较高的比例。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任务。可以从AD工艺前处理、AD和其它干燥方法的联合、干燥系统改进、余热回收以及工艺参数再优化等方面来降低AD蔬菜生产中的能耗。Air Drying （AD） process was widely applied in the drying vegetable because the cheap equipment and easy operation. However, the main disadvantage of this process is the high energy consumption. Therefore, in order to further extend the application, it must be reduce the cost of energy. It is conceived that drying method, optimization of the process, dryer＇s improving, waste --air recycling and application of regenerative energy could further decrease the cost of energy, and discussed in this review.
