　　目前我国已成为世界干果蔬生产和出口的主要国家之一，但是果蔬脱水烘干装置存在加工工艺落后、产品质量较低及能耗大等问题，严重影响经济效益。为此，提出了基于 PLC 控制的太阳能低压果蔬干燥机的设计方案。该方法主要利用太阳能来提供设备能源，在低于50℃的环境下让果蔬近似自然脱水，达到节能环保和降低成本的目的。利用 PLC控制器、干燥箱、增压泵、真空泵、电磁阀和传感器等器件搭建实验样机，初步实验结果表明，太阳能低压果蔬干燥机生产的脱水果蔬具有品质好、色泽好和产品等级高等优点。同时，设备的制造市场经济规模非常可观，产品具有很好的市场前景，极具推广价值。

At present, China has become one of the major countries in the world , which produce and export fruit and vegetable directly , but the present fruit and vegetable drier has several problems that backward processing , lower product quality , energy consumption , which serious impact on economic efficiency .In view of this status , it proposed the re-search of the PLC based solar energy low-voltage fruit vegetable drier .This method mainly makes use of the solar energy to provide equipment energy , and let fruits and vegetables natural dehydrated in below 50℃ an environment to achieve energy saving and reduce costs .It has been built the experimental prototype , which contained the PLC controller ,a drier, a booster pump , a vacuum pump , solenoid valves and sensors etc .Through do the experiment , the preliminary results show that the dehydrated fruits and vegetables production of solar energy fruit vegetable dryer have good quality , good col-or , high grade product advantages .And it has very substantial economies scale for the equipment manufacturing market , so the product has good market prospects and great promotional value .
