Rotary Separator

The Rotary Screener is essential in seed processing plants for grading and calibrating cleaned seeds according to their length. It is versatile and can handle all types of seeds, pulses and grains. The machine is low maintenance and the screens are easy to change. It has high capacity with low power consumption, making it energy efficient. The Rotary Screener is also suitable for narrow spaces.

High-Efficiency Screening: Tanis Rotary Separator

Precision Screening Technology for Seeds, Grains, and Granular Products

In the agriculture and food industry, product quality lies in the details. Especially in seed and grain processing, achieving the right size, unbroken, and impurity-free products is one of the most critical stages for quality.

The Tanis Rotary Separator is a high-capacity, durable screening solution that precisely classifies products according to particle size. Its rotating drum structure provides gentle and balanced processing, even for fragile products, enhancing both quality and production efficiency.

Working Principle: Gentle Screening with a Rotating Drum

  • Multi-layered screening surfaces are placed on the rotating drum.

  • The drum controls the product’s passage time and continuously renews the screen surface to prevent clogging.

  • Different mesh sizes on each layer guide large, medium, and fine particles to separate outlets.

  • Compared to vibration-based systems, the rotary motion is gentler, resulting in lower breakage and smoother product flow.

This structure ensures high efficiency and minimal waste, particularly when processing fragile seeds and grains.

Durable and Flexible Design

  • Interchangeable Screens: Tool-free quick change system for easy adaptation to different products.

  • Modular Capacity: Model options ranging from 3 to 20 tons per hour.

  • Energy Efficient: Low-speed rotary design reduces energy consumption.

  • Full Access Design: Ergonomic drum access for cleaning and maintenance.

  • Automation Compatible: Integration with PLC/SCADA systems for precise control.

Applications

The Tanis Rotary Separator is suitable for a wide variety of products:

  • Cereals: Wheat, barley, rye, corn

  • Pulses: Chickpeas, beans, lentils

  • Oilseeds: Sunflower, canola, sesame

  • Seed Processing: Pre- or post-selection quality control

  • Granular Products: Feed, fertilizers, and other granules

It can be used for pre-screening, intermediate classification, or final quality control stages.

Added Value to Your Operations

  • Improved Product Quality: Homogeneous products through precise particle separation.

  • Reduced Waste: Gentle screening minimizes breakage and defective grains.

  • Flexible Production: Multiple product types can be processed in a single machine.

  • Ease of Maintenance: Quick cleaning reduces downtime.

  • Integration: Compatible with selectors, gravity tables, and color sorters to enhance line efficiency.

Usage Scenarios

  • Pre-classification after a selector

  • Final quality control before packaging

  • Size-based sorting in hybrid seed production

  • Removal of broken grains and foreign particles in pulse lines

  • Achieving uniform particle size in granular product manufacturing

Frequently Asked Questions (FAQ)

  1. Difference between rotary and vibrating screens?
    Rotary screens gently sift products with drum motion, reducing breakage risk. Vibrating systems are harsher, potentially damaging fragile products.

  2. Are screen sizes adjustable?
    Yes. Panels are easily interchangeable for different product sizes.

  3. Can one machine process multiple product types?
    Yes. Quick screen changes allow multiple product types to be processed in the same machine.

  4. Is cleaning and maintenance easy?
    Yes. Ergonomic access points and modular design allow quick drum cleaning.

  5. Can it integrate with automation systems?
    Yes. Compatible with PLC/SCADA for production monitoring and error reporting.

  6. How is the energy consumption?
    Lower than vibrating systems due to low-speed rotary mechanism.

Conclusion

The Tanis Rotary Separator is more than a screening machine—it is a quality and efficiency control point within your production line.

  • High-precision size-based classification

  • Gentle processing with low breakage

  • Flexible structure adaptable to multiple product types

Whether processing seeds, packaging pulses, or producing granules, the Tanis Rotary Separator ensures cleaner, more homogeneous, and higher-quality products.
