Problems solved by technology

Since the air cannot be effectively isolated during the production process, especially the oxygen in the air dissolves in the oil during the stirring process, the oil is easily oxidized and rancid, and the quality stability is poor, which cannot meet people's demand for high-grade and high-quality edible blending oil.

Embodiment 1

[0020] Such as figure 1 As shown, the present invention adopts a sealed oil transfer tank 1, an oil inlet and an air inlet are arranged on the top of the tank, and an inlet regulating valve 2 and an inlet movable joint 3 connected with a flexible pipe are installed on the inlet pipe connected to the oil inlet. The intake pipe connected to the intake port is equipped with an intake control valve 4, an intake pressure gauge 5 and a nitrogen generator 6 (model: CA-T-20), and an exhaust port and an exhaust valve 7 are located at the bottom of the tank top. There is an oil outlet at the lower part of the body, and the outlet pipe connected to the oil outlet is equipped with an outlet regulating valve 8 and an outlet movable joint 9 connected with a hose, and a gear pressure pump 10 is matched with the oil transfer tank 1, and the outlet pipe of the gear pressure pump Outlet pressure gauge 11 is housed on.

[0021] The production technology that the present invention adopts is as f...

Embodiment 2

[0034] This embodiment is basically the same as Example 1, except that the outlet pressure of the gear pressure pump is 0.6Mpa in the process of filling nitrogen and stirring.

Embodiment 3

[0036] This embodiment is basically the same as Example 1, except that the outlet pressure of the gear pressure pump is 0.1Mpa in the process of filling nitrogen and stirring.

Abstract

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 pump, when the exhaust air pressure reaches 0.1-0.6 Mpa, the nitrogen is fed into the blend oil tank from the oil outlet, and the nitrogen with higher pressure is used for stirring the mixed oil in the tank, so that the mixed oil can be blended evenly. In the method of the invention, oxygen which is easy to result in oxidative rancidity of the oil is completely isolated in the stirring process, thereby realizing sufficient mixing and homogeneous blending, and ensuring production of high-quality blend oil.

Description

technical field [0001] The invention relates to a blending method of blended edible oil, which belongs to the field of edible oil production. Background technique [0002] At present, the blending method of edible blending oil is a mechanical stirring method, that is, mixing several different oils in the container according to the weight ratio, and using a motor to drive the mechanical blade to rotate, stirring the mixed oil to make it evenly blended. Since the air cannot be effectively isolated during the production process, especially the oxygen in the air dissolves in the oil during the stirring process, the oil is easily oxidized and rancid, and the quality stability is poor, which cannot meet people's needs for high-grade and high-quality edible blending oil. Contents of the invention [0003] The purpose of the present invention is to provide a circulating pressurized nitrogen-filled stirring method for preparing edible blending oil, so as to isolate the contact betw...
