Circulating pressurized nitrogenization stirring method for blending edible blend oil

The invention provides a circulating pressurized nitrogenization stirring method for blending edible blend oil. The method is characterized in that a sealed blend oil tank is used; the upper of a tank top is provided with an oil inlet and an inlet regulating valve, wherein an air inlet is connected with an air inlet regulating valve and a nitrogen generator; an exhaust port and an exhaust valve are arranged at the lower part of the tank top; and an oil outlet and an outlet regulating valve are arranged at the lower part of a tank body. The technology adopted by the method of the invention comprises the following steps: the first step: feeding oil ingredients; the second step: communicating the inlet air pipe of a wheel gear pressure pump with an oil inlet regulating valve, and communicating an outlet air pipe with an oil outlet regulating valve; the third step: starting the nitrogen generator, and using nitrogen to replace air in the cavity of the tank; and the fourth step: starting the wheel gear pressure pu
