Pressure Lean Phase
Pressure Conveying - Lean Phase
Lean or dilute phase pressure conveying systems use positive displacement blowers to convey materials through a pipeline to a destination where the air and product are separated by a filter.
Applications
Lean phase pressure conveying is particularly suitable for conveying low to moderate capacity materials over medium distances, from single or multiple points to multiple destinations. Versatile and adaptable, the low operating pressures allow less expensive pipelines and fittings to be used and, as such, these systems are often the most cost-effective solution for typical conveying applications.Specifications

Options
A wide variety of options for system and component design is available to suit particular system requirements, including the following:
- weighing and dosing equipment
- specialized feeding systems for cohesive, sticky or lumpy products and other special properties
- air filtration, dehumidification and cooling systems
- noise attenuation systems for blower or fan
- inline sifting, sampling, delumping, metal detection and magnetic separation systems
- stainless steel construction for sanitation or corrosion resistance
- demountable and polished designs to USDA 3A standards for ease of cleaning
- sanitary systems for food, dairy and pharmaceutical products

Pressure Conveying - Dense Phase
Dense phase pressure conveying systems use compressed air to push materials from a single or twin pressure pot system through a pipeline to a destination where the air and product are separated.
Vacuum Conveying - Lean Phase
Lean or dilute phase vacuum conveying systems generally use positive displacement exhausters to provide a vacuum (up to 50%) to convey materials through a pipeline to receiving vessel where the air and product are filtered and separated. Lower capacity fan-based systems are also available.
Vacuum Conveying - Dense Phase
Dense phase vacuum conveying systems use high capacity vacuum pumps (up to 99% vacuum) to convey materials from a feed hopper or silo to a receiving vessel or vacuum hopper where the air and product are separated by a filter. When the vessel is full, the vacuum is isolated and the conveyed product is discharged into the destination silo. The prod...

Reality check for biotech
The new GEA Application and Technology Center (ATC) in Sarstedt, south of Hannover, is neither a showroom nor a substitute for a lab. It is a place for testing, data collection and early decisions. This is where it becomes clear whether a biological concept can become a robust industrial process. That step is bigger than it may seem.
Shifts in food packaging: 4 trends
Thermoforming has long played a central role in food packaging. Now it is facing a major shift. As regulations tighten, materials evolve and costs rise, form fill seal lines must do more than run reliably – they now shape how food stays fresh, affordable and recyclable. Take a look at the key thermoforming trends informing the food packaging and delivery landscape.
