Abstract

To obtain a spouted-pouch package having a high degree of deoxidation by a method in which even a liquid filling which readily lathers can be packed while being inhibited from lathering. [MEANS FOR SOLVING PROBLEMS] A before-packing deoxidation step (1) is performed before a liquid filling is packed into a pouch. The step (1) comprises: a vacuum step (1-1) in which the pouch is evacuated under vacuum; an inert-gas blow step (1-2) in which an inert gas is blown into the pouch after the vacuum step; and a gas-diminishing vacuum step (1-3) in which the gas in the pouch after the inert-gas blow step is discharged under vacuum to diminish the gas in the pouch to a given amount. Thereafter, the pouch is evacuated in a second before-packing evacuation step (2-1) and then packed with the filling. After the packing, gas replacement is conducted.

Description

technical field

[0001] The present invention relates to a method and device for filling and sealing liquid content into a pouch with a spout, in particular to a method for filling and sealing a liquid content into a pouch with a spout, which is suitable for filling and sealing liquid content that is prone to foaming and requires high deoxygenation packaging Method and device thereof. Background technique

[0002] In recent years, people have proposed a kind of scheme that fills and seals liquid foods such as porridges such as cool drinks, gelatinous foods, high-calorie or high-nutrition porridge to the mouth bag. When the content is perishable weakly acidic content with a pH value above 4.6, it needs to be sterilized at a temperature above 100° C., and the liquid content is filled and sealed before being sterilized by distillation. In addition, after filling, the inner lid sealing material such as aluminum foil composite film is melted to seal the opening end of the spout. ...
