The invention relates to a full-automatic instant vermicelli production line, and comprises a starch agitating device, a self-curing scroop machine which can produce instant vermicelli only by one time curing, a time-effect aging device, a washing fluffer device, a quantitative cutting device, a powder agglomate drying device, a powder agglomate cooling device, and a package conveying device which are all sequentially arranged along the direction of transmitting materials. The time-effect aging device comprises a first natural time-effect aging machine, a vermicelli refrigerating machine, a washing fluffer machine, and a washing bean jelly machine for the secondary natural time-effect aging. The producing process sequentially comprises the starch agitating, the self-curing scroop, the time-effect aging, the quantitative cutting, the powder agglomate drying, the powder agglomate cooling, and the package conveying, and also comprises the merely primary self-curing scroop. The time-effect aging comprises the first natural time-effect aging, the vermicelli refrigerating, the washing fluffer, and the secondary natural time-effect aging which can lead the self-curing scroop machine which can produce instant vermicelli only by one time curing to extrude the vermicelli, and the vermicelli is not adhesive. The instant vermicelli cannot become burnt when the instant vermicelli is placedin the boiled water, and the flavor is good.
