The invention discloses solar fruit and vegetable hot air vacuum combined drying equipment and a drying method. The solar fruit and vegetable hot air vacuum combined drying equipment mainly comprises an air pre-heater, an intelligent controller, a solar water heater, a vacuum pump, a water catcher, a drying box, a hot air auxiliary heater, a draught fan and the like. A 'hot air-vacuum' combined drying technology is adopted, not only can the advantages of high drying efficiency and good economy of 'hot air' be displayed, but also the advantages of dryness, sanitation, sterilization, freshness preservation, low temperature, high efficiency and the like 'vacuum' can be utilized, so that not only can the final product which is dried maintain the original color, flavor, taste and appearance, but also various physical activity nutrients in fruit and vegetables can be best preserved; solar energy serves as a main drying heat source, so that solar radiant energy can be fully utilized, a lot of conventional energy can
