Stainless Steel Lean Phase Vacuum Conveying Systems

Lean Phase Vacuum Conveying Systems, also known as Dilute Phase, typically employ positive displacement exhausters (like Roots type) generating up to 50% vacuum. This setup conveys materials through a pipeline to a destination, where separation of air and product occurs in a receiving vessel equipped with a filter or cyclone. Smaller systems may use fans as the primary mover. Materials enter the convey line directly or, for metering, through specialized feeding devices like rotary valves or screw feeders. Products are often suspended in airflow, moving at varying velocities based on particle sizes and densities. Discharge from the receiving vessel can be continuous via a rotary airlock or intermittent through valves.

Key Features:

• Weighing and dosing equipment
• Specialized feeding systems for cohesive, sticky, or lumpy products
• Air filtration, dehumidification, and cooling systems
• Noise attenuation systems
• In-line sifting, sampling, delumping, metal detection, and magnetic separation systems
• Sanitary systems for food, dairy, and pharmaceutical products
• Stainless steel construction for sanitation or corrosion resistance
• Demountable and polished designs meeting USDA 3A standards for easy cleaning
• Stepped convey lines to reduce terminal velocities, abrasion, and degradation
