Embodiment

[0031] Examples, reference figure 1 , An efficient deodorization method for rice bran oil, including the following steps:

[0032] S1: The rice bran oil to be deodorized is heat exchanged with steam condensed water, heated to 50°C, then heated with steam, heated to 120°C, temporarily stored and degassed;

[0033] S2: The rice bran oil degassed in step S1 is subjected to heat exchange through the first heat exchanger, and the rice bran oil is pumped into the deodorization tower through the first canned motor pump, and the rice bran oil is heated to 200°C with steam;

[0034] S3: Input heat transfer oil into the deodorization tower and heat it to 250°C, then enter the deodorization tower for deodorization;

[0035] S4: The deodorized qualified rice bran oil enters the bottom of the deodorization tower, and the deodorized qualified high-temperature rice bran oil is used to exchange heat with the rice bran oil to be deodorized, which reduces the temperature of the deodorized qualified rice...

Abstract

The invention provides an efficient rice bran oil deodorization method, which comprises the following steps: S1, carrying out heat exchange on rice bran oil to be deodorized by using steam condensate,heating to 50 DEG C, then heating to 120 DEG C by using steam, and carrying out temporary storage and degassing; S2, performing heat exchange on the rice bran oil degassed in the step S1 through a first heat exchanger, pumping the rice bran oil into a deodorization tower through a first shield pump, and heating the rice bran oil to 200 DEG C by steam; S3, inputting heat conduction oil into the deodorization tower, heating to 250 DEG C, and deodorizing in the deodorization tower; S4, enabling the qualified deodorized rice bran oil to enter the bottom of the deodorization tower, and performingheat exchange between the qualified deodorized high-temperature rice bran oil and the rice bran oil to be deodorized, so as to reduce the temperature of the qualified deodorized rice bran oil; and S5,after the rice bran oil in the step S4 passes through cooling water and the temperature of the rice bran oil is lower than 30 DEG C, conveying the rice bran oil into a crystallizing tank to obtain deodorized rice bran oil. Through a self-designed heat exchange scheme and the deodorization tower, heat is fully utilized.

Description

Technical field [0001] The invention relates to the technical field of rice bran oil processing, and mainly relates to an efficient deodorization method for rice bran oil. Background technique [0002] Rice bran oil refers to the by-product rice bran obtained in the process of rice processing. It is a kind of rice oil prepared by pressing or leaching. Because of its reasonable fatty acid composition, and containing vitamin E, sterol, oryzanol and other lipids, it is beneficial to the human body. Absorption, it has the beneficial effects of removing cholesterol in the blood, reducing blood lipids, and promoting human growth and development. It has become a recognized nutritious and healthy oil at home and abroad. At present, rice bran oil has received widespread attention from all over the world, becoming the next sunflower oil and corn germ oil. Then another new type of edible oil. [0003] In the existing rice bran oil deodorization process, because of the use of high temperature...
