Abstract

The invention relates to a method for preparing crispy dried sweet potatoes and belongs to the technical field of agricultural product processing. According to the method, fresh white sweet potatoes which are free of worm damage, large in size, smooth in surface and easy to clean are adopted as the raw material, pretreatment including cleaning, peeling and slitting is conducted, then the sweet potatoes are cooked in a pot to be medium-well, transferred to an oven to be baked till surfaces become crispy, soaked with baijiu till the sweet potatoes become wet and soft, taken out, dried, placed in a vacuum fryer to be fried, subjected to centrifugation with a deoiling centrifuge, cooled and subjected to nitrogen-filled packing, and finally the crispy dried sweet potatoes which taste delicious, strong and pure and have a durable aftertaste are obtained.
