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;

[0032] c. When th...

Embodiment 2

[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;

[0043] 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;

Abstract

The invention discloses a process for decoloring rice oil. The process includes (1), feeding oil into an argil mixing tank after the oil is subjected to a dewaxing procedure, and regulating a heater so that the temperature ranges from 95 DEG C to 105 DEG C under the control; (2), enabling oil to flow into a decoloring tank from an overflow pipe on the upper portion of the argil mixing tank after the argil mixing tank is full, and starting the decoloring tank to heat the oil by sandwich steam of the decoloring tank so that the temperature of the oil is increased and reaches 120 DEG C; (3), filtering impurities of the oil by the aid of a leaf filter so as to completely decolor the oil. The process has the advantages that the decolored rice oil is golden and is pure in color degree, nutritional components of the rice oil are unaffected by decoloring procedures, emission of other waste gas or residues is prevented, and environment-friendly production can be implemented; argil is adopted in the integral decoloring procedures mostly, accordingly, the cost is low, an effect is good, and the cost can be saved for an enterprise.

Description

technical field [0001] The invention belongs to the field of food processing and manufacturing, and in particular relates to a rice oil decolorization process. Background technique [0002] Rice is the most important food crop in Asia and the world. 64% of the nutrition of rice is contained in rice bran (rice husk and rice germ), and about 60% of the nutrition is contained in the paste Tianci Guyun rice oil, which is a well-known domestic brand in powder layer and germ (Mizhen). At present, rice oil is extracted from rice skin and germ, and 1 liter of first-grade rice oil can be extracted from 150 kg of rice. In Japan, Taiwan and Southeast Asian countries, it is also known as brown rice oil. It has a long history of research and development and consumption, and it will continue to accelerate. In the future, rice oil will be degreased and separated from rice. [0003] Rice oil alone contains oryzanol, and the content of vitamin E is much higher than that of other cooking oi...
