Rice destoner / rice paddy stone removing machine

Rice destoner is mainly used to remove the stone of rice, and it is composed of an impurity outlet, a clean rice outlet, a big stone outlet, a small stone outlet, and a rice feeding hopper. The special design of outlets on the machine is conducive to fully discharge different impurities, improving the cleaning rate. Why the stones and other impurities can be removed? Because of the difference in weight, they will go out from a specific outlet due to gravity. The cleaning rate is more than 95%, and the rice processed by this machine is very clean, it is not necessary to screen them again.

Why you should use rice destoner?

If you are a farmer with a paddy field, I strongly recommend you to buy such a machine. Why? When the rice is harvested from the field, it contains many impurities such as stone, rice stalk, soil, etc. If you do not remove them completely, rice can not be milled well, which will affect the quality of rice.
