Small rice destoner

Types of small rice destoners

A small rice destoner is a piece of machinery used to separate stones and other impurities from rice. Destoning rice is an important step in the production process to ensure only clean and consumable rice gets packaged for sale to end users. There are many different types of small rice destoners, all of which work on the same principle of air separation. Below is a comprehensive description of some of the different kinds of small rice destoners.

• Gravity-based rice destoners: These rice destoners separate impurities based on their weight. Air-blowing rice gravity destoners have a deck where rice flows. Heavier items like stones fall faster than rice, which is lighter. Fans blowing air to float lighter materials like husks may also be included in the gravity separation deck.
• Air-recycling rice destoners: These machine models reuse air that has been blown through the rice separation deck. This method increases the efficiency of separating impurities from rice.
• Vibration rice destoner: Vibration rice destoners operate using the vibrations of decks. Vibration may be caused by electric motors or drive belts. The rice flows down the vibrating deck, while stones and other impurities fall off the edges due to their inability to follow the same trajectory taken by rice seeds.
• Compound rice destoners: Compound rice destoners use vibration and air separation to separate impurities. The advantage of compound rice destoners is that air separation works better when impurities have been segregated based on weight due to vibrations.
• Pneumatic rice destoners: Unlike other rice destoners that rely on the vibration of decks to separate impurities, pneumatic rice destoners use the principle of airflow to separate impurities. The working principle of a pneumatic rice destoner is that rice is exposed to high airflow pressure, which blows out lighter impurities while the heavier items remain grounded.
