OptiLean™ – Superior Phase with Optimized Dilute Phase Pneumatic Conveying
Optimally designed-right velocity, energy efficient performance - engineered by Indpro.
OptiLean™ is Indpro’s advanced optimized dilute phase pneumatic conveying system designed for efficient, dust-free, and reliable transport of bulk powders and granules. By controlling conveying velocity and airflow dynamics, OptiLean achieves stable material flow, reduced degradation, and higher process efficiency compared to conventional dilute phase systems.
Whether you’re handling plastics, food ingredients, chemicals, minerals, or pharmaceuticals, OptiLean ensures continuous conveying with minimal line wear and maximum production uptime.
Why OptiLean? – The Need for Optimization
Traditional dilute phase conveying often pushes materials at excessively high velocities, leading to:
- Fines and dust generation
- Material degradation or breakage
- Streamers and angel hair (in plastics)
- Higher energy consumption
- Increased pipeline wear
OptiLean solves these issues using a precisely engineered airflow design that maintains just the right velocity high enough for conveying, but low enough to minimize damage.
How OptiLean Works
OptiLean is built around three core engineering principles:
- 1. Optimized Conveying Velocity : The system maintains air velocities just above terminal velocity, preventing slippage while minimizing frictional impact.
- 2. Controlled Particle Distribution : Material moves in a stable, evenly distributed dilute stream, avoiding surges or dense pockets.
- 3. Intelligent Airflow Management : Using design elements like air balance valves, pressure transducers, optimized pickup points, and efficient blower control, the system ensures a uniform flow profile along the pipeline.
This results in a conveying process that is smooth, consistent, and energy-efficient.
| Conveying Type | Traditional Dilute Phase | Dense Phase | OptiLean™ (Optimized Dilute Phase by Indpro) |
|---|---|---|---|
| Material Compatibility | Vast | Limited | Vast |
| Dust Type | High fines and coarse dust, depending on material | Very fine, electrostatically charged micro-dust | Reduced fines, controlled dust levels; minimal streamers due to optimized velocity |
| Streamers | Short to long streamers | Minimal streamers | Short streamers |
| Dust Removal Difficulty | Difficult due to high velocity and turbulence | Very difficult - electrostatic fines cling to pellets | Easy & efficient; controlled velocity reduces dust formation |
| Dust Volume Generated | High | Low | Moderate–Low (significantly lower than traditional dilute phase) |
| Material Degradation | High impact → higher breakage and fines | Minimal degradation | Very low degradation; gentle handling through optimized airflow |
| Investment Cost | Low | High | Moderate (optimized performance at reasonable cost) |
| Energy Consumption | High due to excessive conveying velocity | Moderate | Low-Moderate with velocity optimization |
| Recommended Dust Removal System | PelletPurge® / bag filters for coarse / fine dust | PelletPurge® for low amount of fine dust | PelletPurge® for modern amount of dust |
| Ideal For | Fast throughput but not quality-sensitive products | Fragile materials requiring extremely gentle conveying | Applications needing balance of speed, quality, and low dust |
