The Commercial 50T/D Rice Mill Line of Milling Business is a complete rice processing solution designed for commercial rice mills, agricultural cooperatives, grain processing plants, and investors entering the rice milling business. With a processing capacity of up to 50 tons of paddy per day, the production line is engineered to transform raw paddy into clean, well-milled, and market-ready rice through a continuous and coordinated processing system.
Rice is a valuable staple food, but raw paddy contains impurities, stones, dust, husks, immature grains, and broken kernels that must be carefully separated during processing. To achieve stable rice quality and maximize the recovery of whole grains, each processing stage must be properly controlled. This 50T/D rice mill line integrates cleaning, destoning, husking, paddy separation, rice whitening, polishing, grading, and optional color sorting and packaging into a complete milling solution.
As shown in the equipment configuration, the production line uses bucket elevators and connecting conveyors to transfer materials between different processing machines, helping create a more continuous workflow while reducing unnecessary manual handling.
Rice Milling Process
The standard processing flow of the Commercial 50T/D Rice Mill Line is:
Paddy Receiving → Pre-Cleaning → Destoning → Husking → Paddy Separation → Rice Whitening → Rice Polishing → Rice Grading → Color Sorting → Final Rice Packaging
Each stage is designed to remove specific unwanted materials or improve the appearance and quality of the final rice product.
Main Equipment of the 50T/D Rice Mill Line
1. Paddy Receiving and Feeding System
The process begins with the controlled feeding of harvested paddy into the rice milling line. A stable feeding system helps maintain a consistent material flow throughout the production process.
The feeding equipment is designed to transport paddy smoothly to the following processing stages, helping prevent sudden material accumulation or unstable machine loading.
2. Paddy Pre-Cleaning Machine
Freshly harvested paddy may contain straw, leaves, dust, husk fragments, rope, and other large or light impurities. The pre-cleaning machine removes these unwanted materials before the paddy enters the main milling section.
This stage helps protect downstream equipment and creates cleaner raw material conditions for rice processing.
3. Rice Destoning Machine
Although paddy may look clean after pre-cleaning, it can still contain stones, sand, soil particles, and other heavy impurities.
The destoning machine separates these heavy materials from the paddy according to differences in density and movement characteristics. Removing stones before husking helps reduce equipment wear and protects the milling machines from damage.
4. Paddy Husker
The cleaned paddy is then transferred to the husking machine, where the outer husk is removed from the rice grain.
Because rice kernels can be damaged by excessive mechanical pressure, the husking process is designed to balance husk removal efficiency with grain protection. The objective is to achieve effective dehusking while minimizing broken rice.
After husking, the material generally contains brown rice, unhulled paddy, husks, and a small amount of broken material.
5. Paddy Separator
The paddy separator separates unhulled paddy from brown rice after the husking process.
The separated paddy can be returned for further husking, while the brown rice continues to the whitening section. This recycling process helps improve raw material utilization and supports a more efficient rice milling operation.
6. Rice Whitening Machine
Brown rice still has bran layers covering the rice kernel. The rice whitening machine removes these bran layers to produce white rice.
Proper whitening is important because excessive milling may increase the broken rice rate, while insufficient milling can leave too much bran on the rice surface. The milling process is therefore designed to achieve a balance between rice appearance, milling quality, and whole grain recovery.
7. Rice Polishing Machine
After whitening, the rice can be further polished to improve its surface appearance.
The polishing process helps produce rice with a cleaner, smoother, and brighter appearance, making the final product more suitable for commercial markets where visual quality is an important purchasing factor.
8. Rice Grading Machine
The grading system separates whole rice from broken rice according to particle size.
This allows rice processors to classify the finished product into different grades and better meet the requirements of wholesalers, retailers, food distributors, and other commercial buyers.
9. Optional Rice Color Sorting System
For customers requiring higher-grade finished rice, an optional color sorter can be integrated into the production line.
The system can help remove discolored grains, immature rice, damaged kernels, and other visually defective materials, improving the consistency and market appearance of the finished rice.
10. Rice Packaging System
After grading and optional color sorting, the finished rice can be transferred to a packaging machine.
The packaging system can be configured according to the customer’s required bag size, packaging capacity, and target market. Finished rice can then be prepared for wholesale distribution, retail sales, or further commercial processing.
Rice Mill Line Features
1. Complete 50T/D Rice Processing Solution
The rice mill line integrates multiple processing stages into one coordinated system, covering the major steps required to convert raw paddy into finished rice.
2. Continuous Material Conveying Design
Bucket elevators and connecting conveyors transfer rice between different machines, supporting continuous production and reducing unnecessary manual transportation.
3. Flexible Equipment Configuration
The production line can be configured according to the required rice quality, processing requirements, available factory space, and desired automation level.
Optional systems such as color sorting and automatic packaging can be added to create a more complete rice processing plant.
4. Designed for Commercial Rice Milling
With a capacity of approximately 50 tons per day, this rice mill line is suitable for commercial rice processing businesses that require stable output and continuous operation.
Rice Mill Plant Advantages
1. Improved Rice Processing Efficiency
The integrated processing layout allows paddy to move continuously through cleaning, husking, milling, and grading stages, helping improve overall production efficiency.
2. Better Control of Rice Quality
By processing rice through separate cleaning, destoning, husking, whitening, and grading stages, the line helps improve the cleanliness and consistency of the final rice product.
3. Reduced Manual Labor Requirements
The mechanical conveying and integrated equipment layout reduce the need for workers to manually transfer rice between individual processing machines.
4. Supports Different Rice Market Requirements
The system can produce different grades of rice and can be configured with additional equipment to meet higher requirements for rice appearance and finished product quality.
Benefits
1. Higher Commercial Value for Raw Paddy
Instead of selling raw paddy directly, processors can convert it into finished rice products with greater commercial value.
2. Multiple Revenue Opportunities
In addition to finished rice, by-products such as rice husk, bran, and broken rice can also be collected and utilized for different commercial applications.
3. Suitable for Business Expansion
The 50T/D capacity provides a practical production scale for established rice processing plants, agricultural cooperatives, and growing rice milling businesses.
4. More Competitive Finished Rice Products
Cleaner, more uniform, and properly graded rice can help processors meet the quality expectations of wholesalers, distributors, retailers, and end consumers.
