Rice Destoner for Rice Milling Machine: How They Work Together

A rice destoner for a rice milling machine is normally used to remove stones and other heavy impurities before the paddy enters the huller or milling equipment. A destoner does not replace the rice mill; it performs a different cleaning function in the processing line.

Rice Mill Machine and Destoner Have Different Jobs

A rice milling machine processes paddy by removing the husk and, depending on the system, bran and other layers. A destoner separates stones, sand and other heavy impurities from the grain.

Using both machines together creates a more complete rice-processing workflow.

Where Should the Destoner Be Installed?

For equipment protection, a common arrangement is:

Paddy → Cleaner → Destoner → Rice Huller → Rice Milling → Final Cleaning

Placing the destoner before the huller means stones can be removed before they reach rubber rollers and other working components.

Why Add a Destoner to an Existing Rice Mill?

• Remove stones before they reach the huller
• Reduce unnecessary impact and abrasive wear
• Help protect rubber rollers
• Reduce heavy impurities entering downstream machines
• Improve the overall cleaning process

Can You Add a Destoner Without Replacing the Rice Mill?

In many cases, yes. A stand-alone paddy destoner can be added before an existing rice huller or rice milling machine, provided the capacity and material flow are compatible.

For example: Existing paddy feed → new destoner → existing rice huller.

What About a Destoner After Milling?

A downstream destoner can also be considered when milled rice still contains stones or other heavy impurities. This is a different application from protecting the huller before milling, so the machine should be selected according to the actual material.

Choosing Capacity

Actual capacity depends on grain condition, feed rate, machine configuration and operating conditions.

Conclusion

A rice milling machine and a destoner solve different problems. Adding a suitable destoner to a rice milling line can provide an early stone-removal stage and help protect downstream equipment.
