METHOD AND DEVICE FOR PURING OF OXYGEN-ENRICHED AIR LIQUIDS Russian patent published in 2010 - IPC A23L2/54 

FIELD: food industry.

SUBSTANCE: method for pouring of oxygen-enriched or oxygen-gas liquid mixtures or other gases, specifically drinks into pots such as bottles or jars, provides liquid pouring into pots and the enriched liquid is held in nitrogen atmosphere during pouring process with excessive pressure, mainly in the range of 1-10 BARs, after that it is corked up gastight. The pot is being held in the nitrogen atmosphere, especially pressure which corresponds liquid filling pressure, with excessive pressure before liquid supply and before pressure treatment the pot is blown at least one time, mainly with nitrogen, or vacuumised. Also multiple combined pot treatment by blowing and preliminary vacuumisation can be held. Liquid gas, especially liquid nitrogen or oxygen can be added before vacuumisation. Also before liquid supply into the pot, extruded return gas can be collected and used for blowing treatment of the following pots. Device consists of at least one re-entry component with valve for liquid, at least one gas valve for blowing and/or pressure generation in the pot by nitrogen and partially filled with liquid ring boiler with ability to resist nitrogen pressure in the range of 1-10 BARs. The device also includes inductive sensor for consumption measuring and filling component is connected to supplying channel for liquid with lower side of the ring boiler.

EFFECT: invention provides oxygen consumption decrease in the filling process, because liquid is in the system for a short period of time and there is no oxygen absorption by liquid.
