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 ...
