Commonly Conveyed Products: » Flours and Sugars » Granular and Pelletized Products » Pet Foods » Resins and Compounds » Specialty Chemicals Dilute Phase Conveying Dilute phase pneumatic conveying systems operate on the principle that the solids will be suspended in the conveying line air stream. This is accomplished by metering product into a moving air stream. Types of Dilute Phase: » Dilute Phase Pressure » Dilute Phase Vacuum Negative Airlift Enhanced Dilute Phase Conveying (EDIP) Schenck Process’ Negative Airlift beats belt EDIP is a method to enhance the operation of a conveying in seven ways: dilute phase convey system in order to minimize the speed of the blower under all operating conditions. • Highest efficiency cyclone Performance of the operating equipment is translated • Lower maintenance requirements by EDIP into a tangible conveying velocity set by the • Lower microbial count user. In addition, the system control responds to the • Better product expansion hanging conditions in the convey line to maintain • More direct routing from the desired velocity by changing the blower speed. extruder to dryer – The result is a dilute phase system that dramatically resulting in more efficient reduces power consumption, material degradation use of production space and system wear. • Partial pre-drying of • Minimize velocity in product during dilute phase conveying transport to dryer • Reduce energy consumption • Cleaner, drier • Lower material degradation plant environment • Equipment wear is reduced Pressure Dilute Phase Flow Dilute phase conveying velocities typically are greater than 3500 FPM and material to air ratios are less than 12 to 1. Individual particles in the air stream will have some separation by their suspension in the air stream. Airlocks and Diverters Blowers Schenck Process offers a wide range of airlocks and Whether you need pressurized air or to create diverter valves for multiple pneumatic conveying vacuum pressure, Schenck Process blower applications. packages will consistently provide you with the proper conditions. • Easy to disassemble and clean airlocks for sanitary processes like food and pet food • Both table top and skid • High throughput airlocks with capacities to handle mounted packages available up to 220,000 lbs. of product per hour • Line sizes from 2” to 16” • Diverters are available in 22.5, 30 and 45 degree • Blowers for sanitary or divert angles for use in diverting air-conveyed or industrial applications gravity-flow materials into either • Silencers and enclosures of two destinations; or from for reducing blower noise either of two sources • Full line of replacement valves, to one destination filters, motors and gauges • Airlocks and diverters For engineering the ideal pneumatic conveying are available in system Schenck Process provides table top and skid stainless steel, cast mounted blower packages for pressurized air or iron and aluminum vacuum pressure systems. Commonly Conveyed Products: » Abrasives » Carbon Black » Cereals and Fragile Grains » Coffee » Detergents » Fly Ash » Nuts » Pasta » Pet Food » Plastic Pellets » Sand » Sugar Dense Phase Conveying Dense phase pneumatic conveying systems operate at smaller air volumes and higher air pressures. Materials are pulsed through the convey lines and are ideal systems for handling easily damaged or porous products. Types of Dense Phase: » Vacuum Dense Phase » Batch Dense Phase » Continuous Dense Phase (CDP™) » Low Pressure Continuous Dense Phase (E-finity®) E-finity® – The Most Energy Efficient Continuous Dense Phase Technology Available on the Market E-finity® is a low breakage, energy efficient continuous dense phase pneumatic conveying system. • Improves sanitary conditions and housekeeping • Produces the lowest degradation available • Allows for greater system flexibility • Reduces plant footprint • Lowest horsepower of any dense phase pneumatic system The blower air source can be located nearly anywhere in the plant Vent Multiple E-finity® systems can be operated from a single blower air source E-finity® Blower Schenck Process Continuous Dense Phase Technology Vacuum Dense Phase offers the following benefits: Vacuum Modulating Air Control • Lowest product breakage/degradation is the newest generation of • Ability to operate multiple systems from a single air source vacuum dense phase conveying • True continuous feed allows for use with other continuous processing available on the market. systems VMAC uses specially designed • Reduced control pressure resulting in optimum energy savings modulating air controls that • Simplified air controls for ease of operation automatically correct feed • Comprised of Schenck Process manufactured components conditions based on vacuum • Available with either vacuum or pressure modulation option packages levels. This insures the system for pressurized air or vacuum pressure systems is properly loaded and that the benefits of dense phase are realized. High Efficiency Sifting and Screening Sifting: Screening: » Policing – removal of extraneous material » Control screening » Scalping – remove small percentage of » Multi-deck separation of fines oversize product » Classification – separation by size » De-dusting – removal of fines » De-dusting of dry, powdered and granular » Deagglomeration – breaking of soft lumps products and agglomerates » Suitable for high feed rates » Liquid straining – removal of excess liquid » Handles difficult to screen lightweight from solid products products KEK Centrifugal Sifters Industrial Rotary Sifter for Powder and Granule Processing Features: • High capacity and high-efficiency sifting • Gravity and inline pneumatic conveying designs • Cantilever shaft – no oversized bearing or seal • 30 second screen changes • 7 model sizes • Rates from a few pounds to over 200,000 lbs./hr. • Easy disassembly for cleaning and maintenance In-line Pneumatic Conveying Applications Industrial Kek Centrifugal (Rotary) Sifters for powder processing, can be used for direct in-line installation into pneumatic conveying lines.
