Rice Destoner Machine for Nigeria: Remove Stones and Sand from Rice and Paddy
For a rice mill, farm or grain processor, clean grain is not optional. Stones in finished rice can damage customer trust, while sand and heavy impurities in paddy can reduce milling quality and cause unnecessary wear on downstream equipment. A rice destoner machine separates these heavy materials before milling, packaging or sale.
What Does a Rice Destoner Machine Remove?
A gravity vibrating destoner is designed to separate materials that are heavier than the grain. It can be used for:
- White rice: removing stones, small gravel and heavy foreign materials before packaging.
- Paddy rice: removing sand, stones and soil before milling.
- Other grains: cleaning wheat, beans, corn and similar agricultural products when the correct screen is selected.
The goal is simple: produce cleaner grain and protect the next machine in the processing line.
How Does It Work?
The machine combines vibration, airflow and a tilted screen. Grain and heavy impurities move differently on the vibrating surface. The lighter rice or paddy moves toward the clean-grain outlet, while stones and sand move toward a separate discharge outlet. Operators can adjust the feeding rate, airflow and screen angle for the material being processed.
Where Does the Destoner Fit in a Rice Processing Line?
For paddy processing, a destoner is normally installed after preliminary cleaning and before hulling. For finished rice, it can be used before final packaging as an additional quality-control step. The best location depends on your existing equipment, daily capacity and the type of impurities in your grain.
Choosing the Right Capacity for Your Operation
| Typical Need | Suggested Capacity | Suitable Operation |
|---|---|---|
| Small batch cleaning | About 400 kg/h | Small farms, village mills and trial production |
| Regular rice mill production | About 800-1,000 kg/h | Growing rice mills and grain traders |
| Higher-volume processing | About 2,000 kg/h | Commercial mills and larger processing lines |
Capacity should be chosen according to the actual feed rate, not only the planned daily output. For example, see the Model 28A rice destoner for regular mill production or the Model 45A rice destoner for a higher-capacity line. If your line operates for many hours a day or handles paddy with a high level of sand, ask for a model recommendation before ordering.
Questions Nigerian Buyers Should Ask Before Ordering
- What grain will be cleaned: white rice, paddy, beans, wheat or another material?
- What is the required capacity per hour?
- What voltage and plug type are available at the installation site?
- Which Nigerian port or delivery location will be used?
- What spare parts, operating instructions and export documents are included?
Clear answers to these questions help the supplier recommend the right screen, motor configuration and packing method.
