Method for sterilizing instant balls

The present invention relates to a method for sterilizing instant balls. The sterilizing method comprising the steps of instant balls: After the balls cooked before frozen, then vacuum packed at -26 ℃ ~ -22 ℃; 0.11Mpa ~ 0.12Mpa under pressure, the discharge ball after vacuum packaging into water of 108 ℃ ~ 115 ℃ for 12 minutes to 18 minutes sterilization; raising the pressure to 0.12Mpa ~ 0.15Mpa within one minute, the water temperature was raised to 115 ℃ ~ 122 ℃ sterilization continued for 5 minutes to 15 minutes; the after sterilizing water discharged while injecting cooling water and slowly cooled under reduced pressure to make balls, when the ball was cooled to 20 ℃ ~ 30 ℃ can. Sterilizing method of the present invention is a ready-ball method ball sterilized directly in the frozen state, the ball will adopt -26 ℃ ~ -22 ℃ frozen after vacuum packaging, while maintaining the original shape, but also to ensure the product quality.
