Product Overview


The Suction Type Gravity Destoner is a cutting-edge grain cleaning equipment designed by Golden-Cereal™, a leading manufacturer of rice mill machinery. As a core component in modern grain processing lines, this destoner specializes in separating stones, soil clods, and other heavy impurities from grains through a combination of gravity separation and negative-pressure suction. Unlike traditional destoning machines, it features a compact structure, high efficiency, and dust-free operation, making it ideal for upgrading grain processing workflows.


Features


Sorting Chamber for Precise Separation

At the heart of the Suction Type Gravity Destoner is a specially engineered sorting chamber that leverages gravity differences between grains and stones. This design ensures efficient separation even for small or irregularly shaped stones, which are often missed by conventional machines. What sets it apart is its exceptional effectiveness with brown rice—its gentle handling prevents kernel breakage, maintaining the nutritional value and marketability of the final product.


Energy-Efficient Sieve Structure

The machine’s unique sieve structure is optimized to reduce air consumption, lowering operational costs without compromising performance. Compared to standard destoners, it saves up to 20% in blowing rate, making it an eco-friendly choice for sustainable grain processing. The sieve’s durable material resists wear and tear, ensuring a long service life even under continuous operation.


Negative-Pressure Air Suction System

A standout feature is the integrated negative-pressure air suction technology, which creates a sealed environment to prevent dust leakage. This not only keeps the workspace clean but also protects operators from respiratory hazards, aligning with global occupational health standards. The air volume varies by model: 3200-3400 m³/h for TQSX85B, 3800-4100 m³/h for TQSX100B, and 4800-5200 m³/h for TQSX125A—ensuring consistent suction power across different production capacities.


Robust Technical Specifications

Each model is built for reliability:

· Power consumption is as low as 0.75 kw (TQSX85B and TQSX100B) and 1.1 kw (TQSX125A), minimizing energy costs.

· Weight ranges from 340 kg to 400 kg, allowing easy installation in existing production lines.

· Dimensions (152010502200 mm to 152013802200 mm) ensure it fits into compact spaces without sacrificing performance.


Applications


Rice Processing Industry

The Suction Type Gravity Destoner is indispensable in rice mills, where it removes stones from paddy, brown rice, and white rice. Its precision ensures that rice grains remain intact, reducing waste and improving the quality of final products such as polished rice and rice flour.


Other Grain Processing

Beyond rice, this equipment excels in cleaning other grains like wheat, corn, and barley. It is widely used in flour mills, feed processing plants, and cereal production facilities to eliminate heavy impurities, ensuring raw materials meet strict processing standards.


Small to Large-Scale Operations

With models covering 3.5-8.5 t/h capacity, it suits small family-owned mills, medium-sized agricultural cooperatives, and large industrial grain processing complexes. Its versatility makes it a valuable asset for both local markets and export-oriented production lines.


FAQ


How does the suction type gravity destoner separate stones from grains?

The machine uses a combination of gravity and air flow: grains and stones are fed into the sorting chamber, where vibration causes heavier stones to settle at the bottom, while lighter grains float. Negative-pressure suction then removes dust and lighter impurities, ensuring clean separation.


Is the machine suitable for small-scale rice mills?

Yes. The TQSX85B model (3.5-4.5 t/h capacity) is specifically designed for small operations, with low power consumption (0.75 kw) and compact dimensions (152010502200 mm), making it easy to integrate into limited spaces.


How often does the sieve need replacement?

With regular maintenance, the sieve can last 12-18 months under continuous operation. Factors like grain type and impurity levels may affect lifespan—we recommend inspecting it monthly for wear.


Does it require special installation?

No. The machine comes with a user-friendly design for straightforward installation. It can be connected to existing conveyor systems or elevators in rice mill lines, with technical support available from Golden-Cereal™ for setup guidance.


Can it handle wet grains?

While optimal performance is with dry grains (moisture content below 14%), the sieve structure resists clogging from slightly damp grains, making it versatile for various processing conditions.


The Suction Type Gravity Destoner stands out as a reliable, efficient solution for modern grain processing, combining precision, sustainability, and adaptability to meet the diverse needs of the rice mill equipment and grain processing machinery markets. Its advanced features and proven performance make it a top choice for businesses aiming to enhance product quality and operational efficiency.
