Embodiment 1

[0026] The rice oil degumming and drying process comprises the following steps:

[0027] (1) Close the oil discharge foot valve and the oil outlet valve, add the crude oil into the hydration tank, turn on the agitator, and start adding acid after heating the crude oil to 60°C, the amount of acid added accounts for the mass of the oil 0.05%% of the percentage, continue stirring for 30 minutes after adding the acid, and control the oil temperature at 50°C;

[0028] (2) When the stirring period in step (1) expires, continue to keep the agitator open, add hot water to the oil, and then add brine, the amount of brine added accounts for 7% of the oil mass percentage, continue Stir for 30 minutes, then let stand for 4 hours;

[0029] (3) When the standing period in step (2) expires, open the oil discharge foot valve to release the lower oil foot, then heat the oil to 110°C and enter the drying heat exchanger;

[0030] (4) The oil feet in step (3) enter the oil feet pot, turn on the...

Embodiment 2

[0033] The rice oil degumming and drying process comprises the following steps:

[0034] (1) Close the oil discharge foot valve and the oil outlet valve, add the crude oil into the hydration tank, turn on the agitator, and start adding acid after heating the crude oil to 60°C, the amount of acid added accounts for the mass of the oil 0.3% of the percentage, continue stirring for 30 minutes after adding the acid, and control the oil temperature at 60°C;

[0035] (2) When the stirring period in step (1) expires, continue to keep the agitator turned on, add hot water to the oil, and then add brine, the amount of brine added accounts for 15% of the mass percentage of the oil, and continue Stir for 30 minutes, then let stand for 8 hours;

[0036] (3) When the standing period in step (2) expires, open the oil discharge foot valve to release the lower oil foot, then heat the oil to 130°C and enter the drying heat exchanger;

[0037] (4) The oil feet in step (3) enter the oil foot p...

Embodiment 3

[0040] The rice oil degumming and drying process comprises the following steps:

[0041] (1) Close the oil discharge foot valve and the oil outlet valve, add the crude oil into the hydration tank, turn on the agitator, and start adding acid after heating the crude oil to 60°C, the amount of acid added accounts for the mass of the oil 0.2% of the percentage, continue stirring for 30 minutes after adding the acid, and control the oil temperature at 55°C;

[0042] (2) When the stirring period in step (1) expires, continue to keep the agitator turned on, add hot water to the oil, and then add brine, the amount of brine added accounts for 11% of the mass percentage of the oil, and continue Stir for 30 minutes, then let stand for 7 hours;

[0043] (3) When the standing period in step (2) expires, open the oil discharge foot valve to release the lower oil foot, then heat the oil to 120°C and enter the drying heat exchanger;

[0044] (4) The oil feet in step (3) enter the oil foot p...

Abstract

The invention discloses a manufacturing process of rice essential oil. The manufacturing process is mainly implemented by acidifying and adding salt water, so that no harmful substance can be generated, and no pollution to humans and environment occurs. The degumming is thorough without any other impurity, thus being favorable for processing of the next step. Moreover, nutrients in the rice oil can be effectively protected, a heat exchanger can also effectively protect the nutrients in the rice oil during drying, and the efficiency is high.

Description

technical field [0001] The invention belongs to the field of food processing and manufacturing, and in particular relates to a rice oil degumming and drying 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 (Mi Zhen). 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 coo...
