Problems solved by technology

[0010] In recent years, large domestic state-owned enterprises have attached great importance to this industry. COFCO, Arowana Group, and Zhonggu Group have invested in large-scale rice bran oil production lines in Liaoyang, Liaoning, Qinhuangdao, Hebei, and Bengbu, Anhui respectively. According to the traditional oil processing technology, most of the products are grade 4 rice bran oil, and only a few rice bran oil raw materials can be processed into grade 1 rice bran oil. High-grade rice bran oil production lines are mostly in the state of suspension and semi-stop production, while the rice bran oil market is in a state of short supply

Embodiment 1

[0031] 1) Deodorization, decolorization and deacidification

[0032] The raw material oil is grade 4 rice bran oil, which is transported to the preheater by the feed pump, heated to 200°C by the preheater, and then enters the separator. Under the high vacuum of 200Pa, the raw material oil is evenly distributed in the separator , and then heated to 250°C, reduce the pressure in the equipment to 150Pa, reduce the boiling point of the material, use the difference in boiling point of each substance in the raw material oil, heat the light components such as odorous substances, pigments and low-carbon fatty acids in the raw material oil To the boiling point, concentrate at the top of the separator, and after reaching a certain concentration, send it to the condenser to condense to 45°C and enter the light component receiving tank; the heavy component that has not evaporated is concentrated at the lower part of the separator, and sent to the heavy component receiving tank;

[0050] 1) Deodorization, decolorization and deacidification

[0051] The raw material oil is grade 4 rice bran oil, which is transported to the preheater by the feed pump, heated to 250°C by the preheater, and then enters the separator. Under the high vacuum of 300Pa, the raw material oil is evenly distributed in the separator , and then heated to 280°C, reduce the pressure in the equipment to 200Pa, reduce the boiling point of the material, use the difference in boiling point of each substance in the raw material oil to heat the light components such as odorous substances, pigments and low-carbon fatty acids in the raw material oil When it reaches the boiling point, it is collected at the top of the separator. After reaching a certain concentration, it is sent to the condenser to condense to 55°C and enters the light component receiving tank; the heavy component that has not evaporated is concentrated at the lower part of the separator and sent to the heavy component receiving...

Embodiment 3

[0060] 1) Deodorization, decolorization and deacidification

[0061] The raw material oil is grade 4 rice bran oil, which is transported to the preheater by the feed pump, heated to 220°C by the preheater, and then enters the separator. Under the high vacuum of 250Pa, the raw material oil is evenly distributed in the separator , and then heated to 270°C, reduce the pressure in the equipment to 180Pa, lower the boiling point of the material, and use the difference in boiling point of each substance in the raw material oil to heat the light components such as odorous substances, pigments and low-carbon fatty acids in the raw material oil To the boiling point, concentrate at the top of the separator, and after reaching a certain concentration, send it to the condenser to condense to 50°C and enter the light component receiving tank; the heavy component that has not evaporated is concentrated at the lower part of the separator, and sent to the heavy component receiving tank;

Abstract

The invention discloses a production method of edible rice bran oil. The production method comprises the following steps of: firstly, heating four-stage standard rice bran oil by a preheater and charging into a separator, evenly distributing the materials under high vacuum degree, due to the boiling point difference of various substances, separating light components of raw material oil in an evaporating way by a pressure reducing technology, heating heavy components, charging into a purifier, quickly evaporating, separating aflatoxin and pesticide residue in an evaporating way, filtering the treated rice bran oil, contacting with protective gas in a stripping tower, and discharging in a separating way, wherein the acid value of the rice bran oil discharged out of the tower bottom achieves the standard of first-stage rice bran oil; and dewaxing in a winterization way to obtain the first-stage rice bran oil. According to the production method, the first-stage rice bran oil product with high oryzanol content can be produced. The whole technical process separates by a pure physical method, so that nutrition components can not be damaged; the production method does not need adding of any annexing agents, so that the safety of the product can be guaranteed; and the production method does not generate any waste gas, sewage or solid waste.

Description

[0001] technical field [0002] The invention relates to a production method of edible oil, in particular to a production method of rice bran oil. Background technique [0003] Rice bran oil is a cereal "nutritional oil" obtained by pressing or extracting rice bran, a by-product of rice processing. At the 113th session of the World Health Organization (WHO), edible rice bran oil was selected as the best edible oil. The meeting pointed out that this oil contains a large amount of unsaturated fatty acids, which are essential components of human tissues and can reduce the risk of hyperlipidemia to a certain extent. , the risk of atherosclerosis and coronary heart disease. Rice bran oil is rich in essential fatty acids linoleic acid and α-linolenic acid, the ratio of which is close to 1:1, and the ratio of omega-6 fatty acid to omega-3 fatty acid is about 5:1. This ratio of edible oil is a nutritional Healthy oil recognized by academic circles. The fatty acids, vitamin E, ...
