Method for manufacturing dehydrated vegetables by taking goldball onion as raw material

The invention discloses a method for manufacturing dehydrated vegetables by taking goldball onion as a raw material, so as to increase the kinds of the existing dehydrated vegetables, and solve the problems that the dehydrated vegetable product is discolored, the rehydration property is poor, the taste is poor, and the nutrient content is seriously lost. The method comprises the following steps of raw material selection, brining, draining, prefreezing, sublimation drying, postprocessing, packaging and storing, and concretely comprises the following steps of: selecting and cleaning goldball onion, cutting to strips with 5-8cm length, brining according to a ratio of 1:0.002 and draining; rapidly freezing the material after draining, wherein the freezing temperature is below zero 27 DEG C, and the next-step vacuum drying is prepared; pushing from an outer layer to an inner layer after the material is subjected to freeze dehydration, wherein the drying cycle is 6-8hours, the material loadage of a drying plate is 10-15 kg/m , the temperature of the drying plate is controlled at 70-80DEG C in a drying initial stage of sublimation blooming, the drying intermediate stage is 60 DEG C, and the drying later stage is 40-50 DEG C; and discharging under the environment temperature of 20-23 DEG C and the air relative humidity of below 35%, and finally packaging.
