Input Material
Cleaned paddy containing stones
TQSF Double-Layer Suction Type Destoner: Protect Your Milling Line. Engineered to effectively remove stones and heavy impurities from raw paddy, this double-layer suction type destoner ensures a clean material flow, protecting your downstream huskers and whiteners from damage.

Essential Pre-Cleaning: Suitable for commercial rice processors facing mixed raw grain conditions. The TQSF double-layer suction type destoner separates stones of similar size to paddy using density differences. It is a critical section for maintaining stable milling performance.

See the material before cleaning, the impurity-removal action and the cleaner paddy sent to the next process.

Cleaned paddy containing stones
Gravity and air-flow separation
Stone-free paddy for safe husking
Removes impurities before paddy reaches the husker, protecting downstream equipment and improving process stability.
Selects the machine according to large impurities, light impurities, fine impurities, stones or mixed impurity conditions.
Cleaner paddy helps reduce wear and blockage in huskers, whiteners, separators and elevators.
Machine size, sieve area, air volume and cleaning stage are selected according to line capacity and raw grain condition.
Use air flow, vibration and specific gravity difference to separate stones/heavy impurities from paddy or grain.
Raw or pre-cleaned paddy enters the cleaning or de-stoning section.
Screens, air flow, vibration or gravity separate impurities from useful grain.
Dust, straw, stones or other unwanted materials are removed through separate outlets.
Cleaner paddy moves to husking, storage or the next cleaning stage.
TQSF double-layer suction type destoner is selected by screen width, capacity, air volume and material density difference.
| Model | Capacity | Power | Air Volume | Weight / Size |
|---|---|---|---|---|
| TQSF100×2 | 5000–8000 kg/h | 0.37×2 kW | 8000 m³/h | 400 kg; 1720×1316×1875 mm |
| TQSF120×2 | 8000–12000 kg/h | 0.45×2 kW | 10000 m³/h | 500 kg; 1720×1516×1875 mm |
| TQSF150×2 | 10000–15000 kg/h | 0.50×2 kW | 12000 m³/h | 600 kg; 1720×1816×1875 mm |
Choose TQSF when higher destoning capacity and stronger gravity separation are needed for grain cleaning or rice milling projects.
Selection depends on impurity type, capacity and whether stone removal is required.
Usually before husking to protect downstream machines.
Yes, air suction or dust collection can be considered by model.
