Embodiment 1

[0020] The deep processing method of the rice in the present embodiment, comprises the following steps:

[0021] S1. After washing the paddy, soak it in warm water at 36°C for 1.2 hours, then take it out and drain it, put the paddy into the water, and stir it at a stirring rate of 120r / min for 12min to separate the rice husk from the brown rice;

[0022] S2. Soak the brown rice obtained in step S1 in a 2% sodium citrate aqueous solution for 4 hours, then put it into warm water at 28° C., and stir for 10 minutes to obtain shelled rice;

[0023] S3. Spray the nutrient solution on the surface of the shelled rice obtained in step S2. The nutrient solution is made by mixing carrot juice and kiwi juice at a volume ratio of 1:3; wherein, 0.06 kg of nutrient juice is sprayed per 1 kg of rice ;

[0024] S4. Spray the mixed solution with proportioning concentration of ascorbic acid: 0.08% w / v and cysteine: 0.05% w / v on the rice treated in step S3, spraying 0.02L of the mixed solution p...

Embodiment 2

[0029] The deep processing method of the rice in the present embodiment, comprises the following steps:

[0030] S1. After cleaning the paddy, soak it in warm water at 38°C for 1.8 hours, then take it out and drain it, put the paddy into the water, and stir it at a stirring rate of 140r / min for 16min to separate the rice husk from the brown rice;

[0031] S2. Soak the brown rice obtained in step S1 in a 4% sodium citrate aqueous solution for 6 hours, then put it into warm water at 32° C., and stir for 15 minutes to obtain shelled rice;

[0032] S3. Spray the nutrient solution on the surface of the shelled rice obtained in step S2. The nutrient solution is made by mixing carrot juice and kiwi juice at a volume ratio of 1:3; wherein, 0.08 kg of nutrient juice is sprayed per 1 kg of rice ;

[0033] S4. Spray the mixed solution with proportioning concentration of ascorbic acid: 0.22% w / v and cysteine: 0.2% w / v on the rice treated in step S3, spraying 0.04L of the mixed solution p...

Embodiment 3

[0038] The deep processing method of the rice in the present embodiment, comprises the following steps:

[0039] S1. After washing the paddy, soak it in warm water at 37°C for 1.4 hours, then take it out and drain it, put the paddy into the water, and stir it at a stirring rate of 130r / min for 14min to separate the rice husk from the brown rice;

[0040] S2. Soak the brown rice obtained in step S1 in a 3% sodium citrate aqueous solution for 5 hours, then put it into warm water at 30° C., and stir for 12 minutes to obtain shelled rice;

[0041] S3. Spray the nutrient solution on the surface of the shelled rice obtained in step S2. The nutrient solution is made by mixing carrot juice and kiwi fruit juice at a volume ratio of 1:3; wherein, 0.07kg of nutrient juice is sprayed per 1kg of rice ;

[0042] S4. Spray the mixed solution whose proportioning concentration is ascorbic acid: 0.12% w / v and cysteine: 0.1% w / v on the rice treated in step S3, and spray 0.03L of the mixed solut...

Abstract

The invention discloses a deep processing method for rice. The deep processing method is characterized by comprising the following steps that after being washed, unhusked rice is firstly immersed in warm water at 36-38 DEG C for 1.2-1.8 hours, is then taken out and drained, and is put into water to be subjected to stirring treatment for 12-16 minutes at the stirring rate being 120-140 r / min, and rice husks and brown rice are separated; the brown rice is placed in a sodium citrate aqueous solution with the concentration being 2%-4% to be soaked for 4-6 hours, and then is placed in warm water at28-32 DEG C to be stirred for 10-15 minutes, and shelled rice is obtained; a nutrient solution is sprayed onto the surface of the shelled rice, and the nutrient solution is prepared by mixing carrotjuice and kiwi juice according to the volume ratio being 1:3, wherein 0.06-0.08 kg of the nutrient juice is sprayed onto per 1 kg of rice; a mixed solution comprising, by compounding concentration, 0.08%-0.22% w / v of ascorbic acid and 0.05%-0.2% w / v of cysteine is sprayed onto treated rice, and 0.02-0.04 L of the mixed solution is sprayed on per 1 kg of rice; the obtained rice is dried under hot air at 30-36 DEG C for 1.6-2.4 h, and then polishing is carried out; and the polished rice can be irradiated with ultraviolet light, and deep processing of the rice is completed. Pesticides can be effective degraded, and the nutrient composition of the processed rice is improved.

Description

technical field [0001] The invention relates to a rice processing method, in particular to a rice deep processing method. Background technique [0002] Rice is the product obtained after cleaning, husking, milling, finishing and other steps of rice paddy. Among them, the cleaning step is to use appropriate equipment to remove all kinds of impurities mixed in the rice through an appropriate process to improve the quality of the finished rice; at the same time, use a magnet to remove iron nails and iron filings in the rice to ensure The production of rice is safe. The hulling step is to use a rubber roller huller or an emery huller to remove the chaff of the rice and separate the chaff from the brown rice. The rice milling process is to use a rice mill to grind and rub the brown rice to separate the cortex and endosperm, and then to brush the rice, remove the bran, crush the rice, and dry the rice, so that the rice of the required grade can be obtained. [0003] However, ri...
