Descripción

Gravity Paddy Separator For Rice Cleaning is a professional rice milling machine designed specifically for the physical characteristics of paddy. Paddy has a rough husk, lower bulk density, higher surface friction, irregular particle shape, poorer flowability, and a different suspension velocity from brown rice. These features make paddy difficult to separate efficiently by simple screening or air classification alone. This gravity-type gravity paddy separator uses an inclined reciprocating separation deck and controlled stratification to separate paddy from brown rice according to their differences in specific gravity, friction, particle shape, and terminal velocity. It is widely used in rice cleaning and paddy separation sections of rice milling lines, helping mills obtain cleaner brown rice, reduce paddy carryover, and improve downstream milling stability. With adjustable deck angle, vibration frequency, amplitude, and feed control, it can adapt to different paddy varieties, moisture levels, and husking rates.

Working Principle

After husking, the mixture of paddy and brown rice enters the feed hopper and is evenly distributed onto the inclined gravity separation deck. The deck moves with a controlled reciprocating motion. Because paddy is lighter, rougher, more irregular, and has a lower bulk density and different suspension velocity than brown rice, the two materials stratify on the deck. Brown rice, being heavier and smoother, moves along one path, while paddy, being lighter and rougher, moves along another path. Adjustable deck angle, vibration frequency, amplitude, and discharge splitters allow the operator to fine-tune separation according to paddy variety, moisture content, and husking rate. The separated paddy is returned for re-husking, while clean brown rice is discharged to the next milling stage.

Features

• Gravity-type inclined reciprocating deck: The deck is designed for paddy’s rough husk, irregular shape, and higher friction, using a wear-resistant corrugated surface to promote stable stratification.

• Adjustable vibration and deck angle: Frequency, amplitude, stroke, and tilt angle can be adjusted to match different paddy varieties, moisture levels, and husking rates.

• Paddy-oriented feed and distribution system: The feed hopper and distribution plate reduce bridging and uneven feeding caused by paddy’s low bulk density and poor flowability.

• Precise discharge and paddy return system: Splitter plates and discharge outlets separate paddy and brown rice accurately, with paddy returned for re-husking and clean brown rice sent forward.

Advantages

• High separation accuracy: The machine makes full use of the natural differences between paddy and brown rice in specific gravity, surface friction, particle shape, and suspension velocity.

• Low paddy carryover and low brown rice loss: It reduces paddy mixed into brown rice and brown rice lost in the paddy return, improving rice cleaning quality and milling yield.

• Strong adaptability to different paddy: It handles long-grain, short-grain, bold, and slender paddy, as well as paddy with different moisture content after proper adjustment.

• Stable continuous operation: The gravity-type design, precision bearings, and heavy-duty frame ensure reliable operation in commercial rice mills with low noise and low maintenance.

Beneficios

• Cleaner brown rice for downstream milling: Better paddy separation means cleaner brown rice enters the whitening and polishing stages, increasing whole rice yield and final rice grade.

• Lower downstream load and wear: Reducing paddy carryover decreases the load on huskers, whitening machines, and polishers, extending equipment life.

• Higher production efficiency and lower cost: Energy-efficient operation, low maintenance, and reduced labor requirements lower long-term production costs.

• Fast return on investment: High capacity, stable separation, and low grain loss help rice mills recover investment quickly and maintain consistent daily output.

Conclusión

In summary, the Gravity Paddy Separator For Rice Cleaning is a paddy-focused separation solution for rice mills that need cleaner brown rice, lower paddy carryover, and stable continuous production. By using a gravity-type inclined reciprocating deck and adjustable separation parameters, it effectively separates paddy and brown rice based on their natural differences in density, friction, shape, and suspension velocity.
