Unlike density-based separators that rely solely on weight differences, this gravity separator utilizes a combination of reciprocating motion and controlled air flow to create stratified grain layers, allowing more precise separation even with grains of similar density. The result is reduced over-processing, lower grain breakage, and higher overall yield of premium rice products. Its compact footprint (1.8m × 1.5m × 1.6m) makes it suitable for integration into both new and existing rice milling lines.
The specially designed concave-convex sieve bed creates optimal conditions for grain stratification, with adjustable surface patterns that accommodate different rice varieties. The sieve bed's reciprocating motion (300-400 strokes per minute) combined with controlled air flow separates paddy from brown rice with exceptional accuracy.
Operators can adjust three critical parameters via the touchscreen interface: sieve bed inclination (5-12°), reciprocating frequency, and air flow rate (800-1200 m³/h). These adjustments allow optimization for different rice varieties, moisture levels, and processing requirements, with 10 preset programs stored for common rice types.
The separation process requires only a 3 kW main motor and 1.5 kW blower motor, resulting in specific energy consumption of less than 0.8 kWh per ton of processed rice—significantly lower than density table separators which typically consume 1.5-2.0 kWh/ton.
An integrated aspiration system continuously removes light impurities and hull fragments during the separation process, reducing downstream cleaning requirements and improving overall product quality. This system also helps maintain optimal air flow through the grain bed for consistent separation performance.
Positioned immediately after hulling operations, the separator ensures that only properly dehulled grains proceed to whitening and polishing stages, preventing damage to milling equipment caused by unhulled paddy and reducing over-processing of already hulled grains.
In seed processing facilities, the separator's precise separation capabilities ensure that only high-quality, fully hulled seeds proceed to conditioning and packaging, maintaining the purity and germination potential required for agricultural seed products.
For premium rice varieties like Basmati, Jasmine, and organic rice, where maximum yield and quality are critical, the separator's precise operation minimizes grain damage while ensuring complete separation, directly contributing to the product's market value.
The separator performs best with rice moisture levels between 13-16%. At moisture levels below 12%, grain brittleness increases, potentially causing breakage. Above 17%, grains tend to stick together, reducing separation efficiency. The system includes a moisture sensor that alerts operators when conditions fall outside the optimal range.
Under normal operating conditions, the sieve bed maintains optimal performance for 12-15 months with standard rice varieties. For abrasive varieties or continuous operation, replacement every 9-12 months is recommended. The quick-change design allows sieve bed replacement in less than 2 hours with basic tools.
Yes, with the optional parboiled rice kit, the separator effectively processes parboiled rice by modifying the sieve bed surface pattern, adjusting reciprocating frequency to 320-360 strokes per minute, and increasing air flow by approximately 15%. This specialized configuration accommodates the harder texture and different friction characteristics of parboiled grains.
