The invention provides a solar steam hot air drier capable of drying crops. The device mainly comprises solar radiation, a water replenishing water pump, a solar thermal collector, a steam inflow valve, a steam flow direction, a moisture exhaust opening, circulating fans, a heat exchanger, a net belt, a heat exchanger and a belt drier. Firstly, water is replenished into the solar thermal collectorby a worker, under the solar radiation effect, the temperature of the water is increased, and the water is changed into steam; and the steam inflow valve is switched on, the steam flows into the heatexchangers of the belt drier, the steam in the heat exchangers heats air in the belt drier, under the effect of the circulating fans, the heated air is changed into hot air, when agricultural products pass the solar steam hot air drier, the hot air passes the net belt, moisture of the agricultural products on the net belt is brought away, cooled waste water is drained, and the drying process is completed. The solar steam
