  • Patent number: 4234612
    Abstract: A frying method in which hot oil is discharged upward from nozzles at the bottom of a frying tank at high pressure while a perforated container holding tightly packed noodles is conveyed in a horizontally extending path through the oil. The pressure of the hot oil forces the noodles apart so that they are fried uniformly. The frying of the noodles dehydrates them to the desired degree.
