Embodiment 1
[0020] A processing technology for rice with a long shelf life and low broken rice rate, comprising the steps of:
[0021] S1, removing impurities from the picked rice, air-drying at room temperature, and drying with hot air under stirring to obtain pretreated rice;
[0022] S2. Mix and stir gum arabic and water, add single-walled carbon nanotubes for ultrasonic vibration, vacuum dry, add pretreated rice and mix evenly, the stirring temperature is 6°C, heat in steam, and send it to a rice mill for rolling. The paddy is separated to obtain the husked rice;
[0023] S3, cooling the husked rice to room temperature, polishing, color sorting, and grading to obtain rice with a long shelf life and low broken rice rate.
Embodiment 2
[0025] A processing technology for rice with a long shelf life and low broken rice rate, comprising the steps of:
[0026] S1. Remove impurities from the picked rice, air-dry it at room temperature, and dry it with hot air for 20 minutes under stirring at a temperature of 55° C. to obtain pretreated rice;
[0027] S2. Mix 4 parts of gum arabic and 60 parts of water in parts by weight and stir for 20 minutes. The stirring temperature is 90°C. Add 4 parts of single-walled carbon nanotubes and ultrasonically shake for 18 minutes. The ultrasonic power is 400W. Vacuum dry at a temperature of 70°C for 2 hours, add 100 parts of pretreated rice are mixed evenly, the stirring temperature is 5°C, heated in steam at a temperature of 250°C for 2 seconds, sent to a rice mill for rolling, and the paddy is separated to obtain husked rice;
[0028] S3, cooling the husked rice to room temperature, polishing, color sorting, and grading to obtain rice with a long shelf life and low broken rice r...
Embodiment 3
[0030] A processing technology for rice with a long shelf life and low broken rice rate, comprising the steps of:
[0031] S1. Remove impurities from the picked rice, air-dry it at room temperature, and dry it with hot air for 30 minutes under stirring at a temperature of 45° C. to obtain pretreated rice;
[0032] S2. Mix 10 parts of gum arabic and 40 parts of water in parts by weight and stir for 40 minutes. The stirring temperature is 80°C. Add 8 parts of single-walled carbon nanotubes for ultrasonic vibration for 5 minutes. The ultrasonic power is 450W. Vacuum dry for 4 hours at a temperature of 60°C. 80 parts of pretreated rice are mixed evenly, the stirring temperature is 10°C, heated in steam at a temperature of 240°C for 4 seconds, sent to a rice mill for rolling, and the paddy is separated to obtain husked rice;
[0033] S3, cooling the husked rice to room temperature, polishing, color sorting, and grading to obtain rice with a long shelf life and low broken rice rate....
