Industrial refining production method of rice bran oil and equipment thereof

Abstract

The invention relates to a rice bran oil industrialized refining method and a device for implementing the method. The invention effectively satisfies the rice bran oil refining demands in the rice bran oil industrialized refining. The method is implemented by degumming with water, dewaxing, primary alkali refining, secondary alkali refining, cleaning with water, drying and decolorization, as well as deacidification and deodorization in turn. The device is characterized in that a first crude oil temporary storing tank is connected with a fourth oil pump sequentially through a first oil pump, a hydration kettle, a second oil pump, a pre-cooling tank, a third oil pump and a crystallizing tank, which are connected in series; the fourth oil pump is connected with a first oil refining caldron sequentially through a first frame filtering machine, a second crude oil temporary storing tank and a fifth oil pump; the first oil refining caldron is connected with the water-cleaning caldron sequentially through a sixth oil pump, a second oil refining caldron and a seventh oil pump; the water-cleaning caldron is connected with a decolorization oil pump, a second frame filtering machine, a decolorization oil tank and a deacidification and deodorization kettle through a drying and decolorization kettle; and the deacidification and deodorization kettle is connected with a polishing filter through a shielding pump and a condenser. The invention has the advantages of low production cost, high efficiency, good effect, capability in industrialized mass production and great economic and social benefit.

Description

1. Technical field [0001] The invention relates to the field of chemical industry, in particular to an industrial refining production method of rice bran oil and equipment thereof. 2. Background technology [0002] Rice bran contains not only rich and high-quality protein, but also rich and high-quality fat. In the fatty acid composition of rice bran oil, the unsaturated fatty acid is more than 80%, and the essential fatty acid (mainly refers to linoleic acid) reaches 20-30%. The rice bran oil produced from rice bran has a low content of linolenic acid and a high content of vitamin E. Compared with other edible oils, rice bran oil has the functions of clearing blood cholesterol, lowering blood pressure, accelerating blood circulation, stimulating hormone secretion in human body, and promoting human development. Rich oryzanol can regulate brain nerves and improve intelligence. Therefore, rice bran oil is a nutritional oil beneficial to human health. Due to the particularit...

Problems solved by technology

Due to the particularity of rice bran, the acid value of crude oil is high, and the color is difficult to remove. In the traditional simple production process and equipment, it is difficult to meet the requirements for refining rice bran oil. It is a kind of oil that is difficult to handle. If the rice bran oil is not processed in time, the acid value will rise rapidly with the extension of time, which will have a great impact on the refining rate and color. Therefore, after the rice bran oil is produced, it must be refined in time.

With the development of the oil industry and the continuation of deep processing of oil, my country has also begun to conduct scientific research on the comprehensive utilization of rice bran and rice bran refining. However, due to various reasons, there has not been a mature production method and equipment for rice bran oil refining that has been publicly reported.
