Embodiment 1

[0025] The corn oil drying process comprises the steps of:

[0026] (1) Close the oil discharge foot valve and the oil outlet valve, add the crude oil into the hydration tank, turn on the agitator, and start adding acid after heating the crude oil to 60°C, the amount of acid added accounts for the mass of the oil 0.05%% of the percentage, continue to stir for 30 minutes after adding the acid, and control the oil temperature at 50°C;

[0027] (2) When the stirring period in step (1) expires, continue to keep the agitator open, add hot water to the oil, and then add salt water, the amount of salt water added accounts for 7% of the oil mass percentage, continue Stir for 30 minutes, then let stand for 4 hours;

[0028] (3) When the standing period described in step (2) expires, open the oil discharge foot valve to release the lower oil foot, then heat the oil to 110°C and enter the drying heat exchanger;

[0029] (4) The oil feet in step (3) enter the oil feet pot, turn on the s...

Embodiment 2

[0032] The corn oil drying process comprises the steps of:

[0033] (1) Close the oil discharge foot valve and the oil outlet valve, add the crude oil into the hydration tank, turn on the agitator, and start adding acid after heating the crude oil to 60°C, the amount of acid added accounts for the mass of the oil 0.3% of the percentage, continue stirring for 30 minutes after adding the acid, and control the oil temperature at 60°C;

[0034] (2) When the stirring period in step (1) expires, continue to keep the agitator open, add hot water to the oil, and then add salt water, the amount of salt water added accounts for 15% of the oil mass percentage, continue Stir for 30 minutes, then let stand for 8 hours;

[0035] (3) When the standing period described in step (2) expires, open the oil discharge foot valve to release the lower oil foot, then heat the oil to 130°C and enter the drying heat exchanger;

[0036] (4) The oil feet in step (3) enter the oil feet pot, turn on the s...

Embodiment 3

[0039] The corn oil drying process comprises the steps of:

[0040] (1) Close the oil discharge foot valve and the oil outlet valve, add the crude oil into the hydration tank, turn on the agitator, and start adding acid after heating the crude oil to 60°C, the amount of acid added accounts for the mass of the oil 0.2% of the percentage, continue stirring for 30 minutes after adding the acid, and control the oil temperature at 55°C;

[0041] (2) After the stirring period in step (1) expires, continue to keep the agitator open, add hot water to the oil, and then add salt water, the amount of salt water added accounts for 11% of the oil mass percentage, continue Stir for 30 minutes, then let stand for 7 hours;

[0042] (3) When the standing period described in step (2) expires, open the oil discharge foot valve to release the lower oil foot, then heat the oil to 120°C and enter the drying heat exchanger;

[0043] (4) The oil feet in step (3) enter the oil feet pot, turn on the ...

Abstract

The invention discloses a corn oil drying technology. According to the corn oil drying technology disclosed by the invention, by mainly adding acid and brine, no any hazardous substances can be generated, no pollution to human and environment is generated, degumming is complete, no other impurities are generated, next procedure processing is facilitated, nutrients in corn oil can be effectively protected, the nutrients of the corn oil can also be effectively protected by a heat exchanger during a drying process, and the efficiency is high.

Description

technical field [0001] The invention belongs to the field of food processing and manufacturing, and in particular relates to a corn oil drying process. Background technique [0002] Corn oil contains oryzanol alone, and the vitamin E content is much higher than other edible oils. In addition, corn oil has a higher smoke point. Compared with other household oil products, frying oil has a little less smoke and is healthier. The content of saturated fatty acid per 100 grams of corn oil is 23.2, the content of monounsaturated fatty acid is 42.2, and the content of polyunsaturated fatty acid is 34.5, the ratio is close to 1:1:1, which is close to the standard recommended by the World Nutrition Association. It is a high-quality natural Healthy Oils. [0003] Corn oil needs to be dried during the production process. The drying process pollutes people and the environment, and the degumming is not complete, and impurities are often mixed in the oil. Contents of the invention [0...
