Rice milling steps

Rice milling has evolved significantly over the years. Today, modern milling methods use advanced techniques to improve yield and produce high-quality white rice from paddy. The process involves multiple steps, such as cleaning, husking, polishing, and grading, to ensure better efficiency and superior rice quality. For those new to rice milling, seeking guidance from experienced rice mill consultants can be highly beneficial. They provide expert advice on improving productivity, reducing waste, and using the best technology. With the right approach, rice mills can achieve higher efficiency, better rice quality, and increased profitability in the long run.

Rice milling has improved a lot over the years. Modern techniques help produce more rice and better-quality white rice from paddy. The process includes several steps for better efficiency. If you are new to rice milling, consulting experts can help improve productivity, reduce waste, and enhance overall rice quality..

What is milling process

Rice milling is the process of removing the husk and bran layers from paddy to produce clean, white rice suitable for consumption. This process enhances the rice’s texture, appearance, and shelf life. Typically, milled rice consists of about 20% husk, 8-12% bran, and 69% starchy core, depending on the milling level. Proper milling ensures that impurities are removed while preserving the essential nutrients in the rice. Advanced milling techniques help improve rice quality, reduce waste, and increase efficiency. The final product is polished, free from unwanted materials, and ready for cooking or further processing in food industries.

Modern Rice Milling Process

The modern rice milling process consists of five key components. Let’s explore each of them in detail.

1. Cleaning

The main purpose of the cleaning process is to remove unwanted materials like stones, immature grains, and other impurities from paddy before milling. While it doesn’t remove dust, it helps improve milling efficiency and recovery rates.

Cleaning before husking and whitening offers several benefits:

Keeps the rice mill clean and hygienic.

Prevents wastage of paddy mixed with stones.

Reduces grain breakage.

Enhances milling capacity.

The cleaning process involves passing paddy through three key machines: a pre-cleaner, a classifier, and a de-stoner, ensuring better rice quality and efficiency.

2. Dehusking or dehulling

Dehusking, also known as dehulling, is the process of removing the outer husk (chaff) from rice grains. Traditional hulling machines have a shelling efficiency of only 60-70%, often leading to higher grain breakage and ineffective separation of paddy from brown rice.

To improve efficiency, it is essential to install advanced equipment such as pneumatic rubber shellers, tray separators, and husk separators in the dehusking section. These upgrades offer several benefits:

Increase milling capacity by 5%.

Reduce rice breakage.

Lower costs on consumables and maintenance.

Remove impurities like oversized and immature grains, ensuring better rice quality.

3. Whitening or polishing

The whitening or polishing process removes the bran layer from rice, making it ready for consumption and market standards. Installing vertical whiteners and silky polishers in a modern rice mill offers several benefits:

Improves the whiteness of rice.

Increases whole grain yield by reducing breakage.

Enhances the appearance of rice kernels, making them more appealing.

These advanced machines ensure high-quality rice with a smooth finish, meeting both consumer and industry demands efficiently.

4. Grading

Grading helps mill owners maximize head rice yield while keeping broken rice for further processing. Using thickness graders, rotary sifters, and length graders offers several advantages:

Efficiently separates broken rice from whole grains.

Reduces the amount of broken rice mixed with head rice.

Boosts productivity by speeding up the grain separation process.

These machines ensure better rice quality, improve efficiency, and enhance overall milling performance.

5. Colour Sorting

Color sorting is an important step in rice milling that uses advanced technology to separate rice grains based on their color.

Here’s how it works:

Machine: A color sorter uses special cameras and lighting to scan each grain as it moves on a conveyor belt.

Detection: The system identifies defective grains, such as discolored, chalky, immature, or broken rice, along with any foreign particles.

Separation: Using air jets or other methods, unwanted grains are removed, ensuring a clean, uniform, and high-quality batch of rice.

This process improves rice quality, making it more appealing and market-ready.
