Rice, an indispensable staple food for Chinese people, undergoes continuous technological advancement in its processing. The typical rice milling process encompasses multiple meticulous steps, including cleaning, stone removal, rice-rice separation, rice milling, and rice polishing.
1. Rice Cleaning
This step primarily involves using equipment such as drum pre-cleaners, vibrating screens, and stone removers to perform preliminary cleaning and remove impurities from the rice.
2. Rice Hulling
Hulling is a critical step in rice processing. The rice huller, combined with air separation equipment, effectively removes the husks, resulting in a rice-rice mixture.
3. Paddy Separation
The rice-rice mixture is then finely separated using a rice-rice separation screen to ensure smooth processing in subsequent processes.
4. Unripe Grain Separation
Large rice mills often employ specialized methods to separate unripe grains from the rice to ensure high quality.
5. Rice Milling
Rice milling is performed using a rice mill, typically using a two-iron process. A polishing machine is sometimes used for fine processing to enhance the rice’s whiteness and texture. Rice processing techniques may vary from region to region, but the goal is to improve rice quality.
6. White Rice Grading
The milled rice is finely graded using a white rice grading screen to ensure uniform particle size.
7. Color Sorting
Color sorters, such as the Swiss Bühler Setex Z series, are used to color-sort the rice, removing color variations and impurities, further enhancing rice quality.
8. Polishing
Some mills may choose to polish the rice before color sorting to enhance its color and smoothness.
9. Re-Grading
After color sorting and polishing, the rice is graded again to ensure consistent final product quality.
10. Packaging
The graded rice is packaged for transportation and sale.
