Embodiment 1

[0025] A method for oil production from rice bran, comprising the steps of:

[0026] (1) Cleaning of rice bran

[0027] The fresh rice bran is screened or winnowed to remove impurities in the rice bran, crushed, and passed through a 25-30 mesh sieve;

[0028] (2) Add shell and add water

[0029] Add 7wt% rice husks crushed to 1 / 6 of the cleaned rice bran in step (1), and mix evenly to increase the hardness of the billet. Steam can easily pass through the billet when frying the billet, and then spray it with water to moisten it. Make described rice bran water content be 15wt%;

[0030] (3) Steaming and frying of rice bran

[0031] Then steam and fry the rice bran treated in step (2) with a steam frying machine, the steam frying machine speed is 50-60r / min, the steam frying temperature is 112°C, and the steam frying time is 15min, so that the moisture content of the rice bran reaches 37wt %, to obtain cooked body;

[0032] (4) Fried billet

[0033] Put the cooked body obta...

Embodiment 2

[0040] A method for oil production from rice bran, comprising the steps of:

[0041] (1) Cleaning of rice bran

[0042] The fresh rice bran is screened or winnowed to remove impurities in the rice bran, crushed, and passed through a 25-30 mesh sieve;

[0043] (2) Add shell and add water

[0044] Add 5wt% rice husks crushed to 1 / 6 of the cleaned rice bran in step (1), and mix evenly to increase the hardness of the billet. Steam can easily pass through when frying the billet, and then spray it with water to moisten it. Make described rice bran water content be 18wt%;

[0045] (3) Steaming and frying of rice bran

[0046] Then steam and fry the rice bran treated in step (2) with a steam frying machine, the speed of the steam frying machine is 50-60r / min, the steam frying temperature is 120°C, and the steam frying time is 30min, so that the moisture content of the rice bran reaches 32wt%. get cooked body;

Abstract

The invention provides a method for producing oil by utilizing rice bran. The method comprises the following steps that 1, rice bran is cleaned; 2, shells and water is added; 3, the rice bran is steamed and stir-fried, wherein the rice bran processed in the step 2 is steamed and stir-fried by using a steaming and stir-drying machine to obtain cooked germs, the rotating speed of the steaming and stir-drying machine is 50-60 r/min, and the rice bran moisture is up to 32%-37%; 4, germ stir-drying is performed, wherein the cooked germs obtained in the step 3 are put in an iron pan for baking and stir-drying; 5, squeezing is performed, wherein a c cake block obtained in the step 4 is put in an oil press and is jacked in the oil pressing process, slow force exertion is performed for squeezing, the squeezing temperature is 80-90 DEG C, and the time is 3-5 minutes; 5, filtration is performed; 6, hydration and dehydration are performed. The method for producing oil by utilizing the rice bran uses the rice bran as a raw material, adopts a squeezing technology and is simple in process, high in oil yield and free of pollution, and process conditions are suitable.

Description

technical field [0001] The invention belongs to the technical field of grain and oil processing, and in particular relates to a method for producing oil from rice bran. Background technique [0002] my country is the largest rice producer in the world. Rice bran is the main by-product of rice processing. When rice is processed, about 7%-10% of rice bran can be obtained. Rice bran contains 16%-20% oil, and rice bran oil is a Vegetable oils with higher unsaturated fatty acid content have higher nutritional value. [0003] At present, the most widely used rice bran oil extraction processes are pressing and leaching. The leaching method uses organic solvents to soak rice bran to extract oil. This method is low in cost and high in oil yield, but it is prone to solvent residues. Hazard to people's health. Contents of the invention [0004] In view of the above technical problems, the purpose of the present invention is to provide a method of using rice bran to make oil. The met...
