Pharmaceutical Dense Phase Conveying

Dense Phase Conveying Equipment.jpg

Dense phase systems convey materials at slower velocity than traditional dilute phase pneumatic systems. Unlike dilute phase conveying, in which all the material is suspended in a high speed gas stream, dense phase conveying moves material in a slower but more concentrated manner, especially along the bottom of the pipeline. The dense phase system will be designed to move material in a strand, plug, or fluidized mode depending on the nature of the material and the plant configuration.

Key Features

  • Feedback – Traditional dense phase conveying can experience problems if there is any change to the material, operational distance or rate, or environmental conditions. Coperion K-Tron’s dense phase feedback can sense these changes, make compensations, and provide the needed reliability. Virtually all pneumatic conveying systems can provide some intelligence at the source and at the destination, but no information feedback along the conveying line. The Coperion K-Tron dense phase system has the capability of providing pressure and flow information at the source, along several points on the convey line and at the destination(s). This is particularly useful when optimizing the system for minimal air consumption (especially if the system is to handle multiple materials). In addition it makes troubleshooting the system easy and intuitive. Lastly, if a plug should form in the convey line, it can be immediately detected, easily be located and typically resolved without physically disassembling the convey line.
  • Simplicity – Units are pre-assembled to reduce installation cost, requiring only compressed air source and electrical power. Turnkey installation available.
  • Controls - Proper control is vital to successful dense phase conveying. Our experienced electrical engineers and programmers have the experience to match any customer’s control needs. A variety of control PLC and communication options are available.
  • Customization – Each Coperion K-Tron system is proposed to exactly match the intended application. This includes an environmental evaluation to make sure that all maintenance access and space allocations are taken into consideration.
  • Cleanability – In both the pressure vessel and continuous high pressure rotary valve dense phase configurations, the vessel and the convey line can easily be purged of material. Provisions are available for inspection/cleanout of the system components. Sanitary versions of both types of dense phase systems are also available utilizing Tri-Clover type clamps wherever feasible.
  • Quiet – Dense phase systems operate at noise levels well below 83 dBa.
  • Durability/Reliability – Coperion K-Tron dense phase systems purposely have additional safety factors built in to materials of construction and performance to reduce maintenance, while providing a long life cycle.
