The 20-ton rice milling production line combines unparalleled efficiency, premium quality, and advanced automation into a single integrated solution. Engineered to deliver a consistent daily output of 20 tons of premium-grade rice, this cutting-edge system integrates cutting-edge processes such as de-stoning, husking, milling, grading, color sorting, and packaging, all optimized for precision and reliability.
With its flexible and customizable design, the production line adapts seamlessly to diverse user requirements, making it an ideal choice for processing a wide range of rice varieties with precision and multifunctional capabilities. Tailored for large-scale rice factories, this technological marvel offers a versatile, streamlined, and future-ready solution, perfectly suited to meet the demands of today’s competitive rice processing industry.
Which machines are included in the entire rice production line?
Based on a 20-ton automatic rice mill plant, this commercial large-scale complete rice milling production line adds a polishing machine, white rice grading, color sorting, weighing, and packaging. In addition, you can also add a silo to store the white rice and then pack it.
The entire rice production line does not require all machines to work at the same time. For example, in the early stage of rice milling, the color sorter and packaging machine do not need to be turned on. When the quantity of rice is large, the color sorter can be turned on and then weighed and packaged, which can reduce the waste of electricity resources.
Single machine advantages
Unique combination cleaning and stone removal machine
- Separate structure for efficient cleaning and stone removal.
- Multi-layer reciprocating vibrating screen ensures high cleaning efficiency and thorough impurity removal.
- Large air volume suction system enhances stone removal performance.
- Equipped with high-strength vibration-damping bearings for smooth operation, low vibration, low noise, and minimal dust.
Innovative strong drawing wind sand roller
- Emery roller rice mill features a large-diameter hollow main shaft and innovative “sand roller whitening” design.
- Strong wind blower maintains low rice temperature, results in cleaner rice, and enhances rice gloss while reducing breakage rate.
- Reduced operational height for easier operation and convenient daily maintenance.
Stable gravity separation for brown rice and paddy
- Large screen surface design enables fast separation and uniform material distribution.
- Adjustable horizontal and vertical screen angles ensure optimal screening performance for all rice varieties.
- Minimal re-husking required, effectively reducing the broken rice rate.
White rice grading sieve
- White rice grading sieve classifies finished rice into three grades: first-grade rice, large broken, and small broken.
- Also suitable for separating other similar granular materials.
Rice color sorter
The rice color sorter efficiently eliminates tiny spots, husks, grass seeds, yellowed grains, white belly grains, discolored or mildewed rice, and small stones—ensuring only high-quality rice remains.
Packing machine
The packing range covers 5 to 50 kg, making it suitable for various weights such as 5 kg, 10 kg, 25 kg, 30 kg, 35 kg, 40 kg, and 50 kg—all easily handled with this packaging machine.

Workflow of 20-ton rice milling production line
The 20-ton rice milling production line is designed for streamlined and efficient rice processing from raw paddy to finished product. The process begins with the paddy being conveyed and cleaned, followed by dehusking, milling, and final packaging. Each stage is interconnected through a carefully designed flow that ensures quality output and minimal waste.
Initial conveying and cleaning
Paddy rice is transported by a single-chain elevator to the cleaning unit, where large impurities and stones are removed.
Dehusking stage
A double-chain elevator delivers the cleaned rice to a dehusking machine that separates the husk from the grain. The husk is either expelled by a fan or sent to a grinding machine.
Separation of unhulled rice
The mixture of brown and unhulled rice is sent via another double-chain elevator to a gravity sieve. This unit separates unhusked grains and redirects them back to the dehusking machine.
Milling and bran separation
Brown rice is passed to a milling machine for whitening. The bran produced is extracted by a bran sifter and separated into fine and coarse bran.
Bran processing and collection
The fine and coarse bran are combined and fed into a grinding machine for uniform mixing, then collected and packaged as a finished bran product.
Finished rice packaging
The milled and polished rice is collected, graded, and packaged as the final product, ready for distribution.
This integrated workflow ensures high output, consistent rice quality, and efficient resource utilization throughout the entire milling process.
How to install such a rice milling production line?
As shown in the picture below, we will number them in sequence. You only need to assemble according to this serial number. In addition, if you encounter any problems during installation, you can contact our engineers.
Maintenance of 20-ton rice milling production line
- Conduct maintenance every 1000 operating hours, including disassembling the bearings, cleaning, and replacing lubricating grease.
- Promptly address any damage or significant wear on machine components, ensuring that the repaired rotor undergoes dynamic balancing verification.
- When the machine is idle for an extended period, ensure thorough cleaning of the interior, removing dust and debris to prevent rust and potential sieve hole blockages.
Is it profitable to invest in such a rice milling production line?
Investing in a complete rice milling production line can indeed be a profitable venture, considering the widespread cultivation of rice in many African countries. Establishing a rice mill workshop provides an opportunity to offer milling services to local households, generating income through processing fees.
Additionally, the byproduct, rice husk, opens up another avenue for revenue. Rice husk can be utilized as a valuable resource, serving as a source of poultry feed. This not only provides an eco-friendly solution for waste management but also caters to the needs of local poultry farmers. Moreover, you can explore selling rice husks to livestock farms, expanding your market, and contributing to sustainable agricultural practices.
In essence, investing in a rice milling production line not only supports local communities by offering milling services but also allows you to tap into the various revenue streams associated with rice processing and the utilization of byproducts.
