DEAERATOR AND DEAERATION METHOD Russian patent published in 2017 - IPC B01D19/00 C02F1/20 C02F103/02 

FIELD: food industry.

SUBSTANCE: fluid deaeration method comprises the stages at which the fluid is compressed to a pressure above atmospheric pressure, the fluid is heated to a predetermined temperature, the compressed fluid is guided to the site of mixing, an inert gas is admixed to the compressed fluid, the compressed fluid comprising an inert gas is fed to the separation tank through the depressurization valve, the pressure in the separation tank is reduced to a pressure above the vapour pressure for said fluid at said predetermined temperature, the separated gases are pumped from the separation tank, and the deaerated fluid is pumped from the separation tank for further processing. The fluid deaeration system comprises the heater (108) of the fluid to a predetermined temperature, the means (104) for fluid compression, the pipe for guiding the heated fluid into the separation tank (114) through the depressurization valve (110), the adjustable vacuum pump (116) for pumping deaerated gases from the tank (114), the pipe for guiding the deaerated fluid from the tank (114), the inert gas source and the mixer (106) for supplying an inert gas into the fluid.

EFFECT: improved energy efficiency of the deaeration process.
