The invention relates to a method for fast preparing dry pumpkin, and belongs to the technical field of farm product processing. The method comprises the following steps of firstly, uniformly and flatly laying fresh pumpkin slices onto a water-removing container, wherein the thickness is 3 to 5cm; feeding the fresh pumpkin slices into a water-removing chamber; performing water-removing for 42 to 52 seconds at 62 to 67 DEG C; obtaining the water-removing pumpkin; then, performing natural cooling and strong force cooling to 20 to 40 DEG C; then, putting the cooled pumpkin into drying equipment; drying the pumpkin in a multi-section drying mode to obtain the dried pumpkin (during the multi-section drying, the drying in a mode of hot air inlet at the upper side and air outlet at the lower side is used for the drying of odd number section, and the drying in a mode of hot air inlet at the lower side and air outlet at the upper side is used for the even number section; during the drying, the temperature is controlled to be 71 to 78 DEG C; the total drying time is 40 to 60 minutes); after the drying, performing resurgence to obtain a finished product. The method has the advantages that the process is simple; the efficiency is high; the performance of the obtained product is excellent and stable; meanwhile, the high-quality product yield is high; the production and application in the large-scale flow line can be convenient.
