Embodiment 1
[0026] The rice oil decolorization process comprises the steps:
[0027] (1) After the oil has gone through the dewaxing process, it enters the clay mixing tank and adjusts the heater to keep the temperature at 95°C;
[0028] (2) When the clay mixing tank is full, the oil enters the decolorization tank from the overflow pipe on the upper part of the clay mixing tank, and the interlayer steam heating of the decolorization tank is turned on to raise the oil temperature to 120°C;
[0029] (3) Filter impurities through leaf filter to complete decolorization. The filtering of impurities through the blade filter includes:
[0030] a. Close all valves of the filter;
[0031] b. When the liquid level of the oil in the decolorization tank reaches half and the sight glass of the inlet pipe shows that the oil has entered, open the overflow valve of the filter and the decolorization pump, and slowly open the oil inlet valve, so that the oil slowly enters the filter;

[0038] The rice oil decolorization process comprises the steps:
[0039] (1) After the oil has gone through the dewaxing process, it enters the clay mixing tank and adjusts the heater to keep the temperature at 105°C;
[0040] (2) When the clay mixing tank is full, the oil enters the decolorization tank from the overflow pipe on the upper part of the clay mixing tank, and the interlayer steam heating of the decolorization tank is turned on to raise the oil temperature to 120°C;
[0041] (3) Filter impurities through leaf filter to complete decolorization. The filtering of impurities through the blade filter includes:
[0042] a. Close all valves of the filter;
