Abstract
The invention relates to a method for manufacturing dehydrated sweet potato vine powder, belonging to the field of food processing technologies. The method comprises steps of selecting materials, chopping by a machine, washing and removing peel through ultrasonic, selecting by a machine for the first time, grading manually, steam exploding, rolling into powder, drying, sorting and packaging. The method comprises the step of steam exploding, under huge pressure difference, saturated steam carries out adiabatic expansion on the sweet potato vine so as to ripen the sweet potato vine, and the steaming step is omitted, so that energy consumption is reduced, after steam exploding, the material is cooled to room temperature rapidly, the step of cooling the material can be saved and the next production chain can be directly carried out, the production speed can be accelerated, labor cost is reduced, the cost price of the equipment is saved, and the method is sanitary.
