Embodiment 1
[0034] A physical deacidification and deodorization system for vegetable oil, including a set of processing devices;
[0035] The treatment device includes a dehydration tower 1, a deacidification tower 2, a decolorization tower 3 and a deodorization tower 4;
[0036] Dehydration tower 1, deacidification tower 2, decolorization tower 3 and deodorization tower 4 are packed towers;
[0037] The oil outlet of dehydration tower 1 is connected with the oil inlet of deacidification tower 2, the oil outlet of deacidification tower 2 is connected with the oil inlet of decolorization tower 3, the oil outlet of decolorization tower 3 is connected with the oil inlet of deodorization tower 4 Port connection; the vegetable crude oil is processed in a progressive temperature manner to avoid energy consumption caused by temperature fluctuations in the processing process of the vegetable crude oil, making the design of the deodorization system more reasonable;
[0038] The oil outlet of deod...

[0049] The vacuum degree of deacidification tower 2 is 1mbar, the temperature is 230°C, and the deacidification time is 3min;
[0050] The vacuum degree of the decolorization tower 3 is 1.5mbar, the temperature is 240°C, and the decolorization time is 2min;
[0051] The vacuum degree of the deodorization tower 4 is 0.8mbar, the temperature is 260°C, and the deodorization time is 1min.
Embodiment 3
[0053] The difference from Example 1 is that the vacuum degree of the dehydration tower 1 is 11 mbar, the temperature is 150° C., and the dehydration time is 2 min;
[0054] The vacuum degree of the deacidification tower 2 is 1.5mbar, the temperature is 220°C, and the deacidification time is 10min;
[0055] The vacuum degree of the decolorization tower 3 is 1mbar, the temperature is 240°C, and the decolorization time is 8min;
[0056] The vacuum degree of the deodorization tower 4 is 1 mbar, the temperature is 270° C., and the deodorization time is 5 min.
