There are many types of mechanical conveying systems and equipment which may be integrated into a powder handling system, two types frequently preferred for hygienic powder handling systems are auger type screw conveyors and vibratory conveyors.

 

Screw Conveyors

A helical shaft is turned to gently push powder through the conveyor from the inlet to the discharge point. Screw conveyors are particularly suitable for the controlled metering of powder flow and when large lumps may be present. Available with an almost limitless variety of options including:

  • Long units and multiple augers for large horizontal distances
  • Inclined units for vertical lifts
  • Hand Demountable shaft removal options
  • Auger flight and pitch designs to suit application, standard, half/double, reverse, variable, conical, paddle types
  • Tubular or trough designs with hinged access covers for inspection/cleaning
  • Multiple intake and discharge points
  • VFD drives for precision metering and weighing applications
  • CIP Cleanable equipment designs and accessories
  • ATEX Rated components for hazardous areas
  • Sanitary sdesigns to USDA / 3A / EHEDG standards are Technopak’s specialty

 

Vibrating Tube Conveyors

Vibration is used to gently glide powder down an inclined tube from the inlet to the discharge point.  Vibro-tubes are ideal for the hygienic transfer of powders along shorter horizontal distances, and are available with a range of options:

  • No moving parts for negligible maintenance and easy cleaning
  • Multiple intake and discharge points
  • Bi-directional units available
  • Floor mounted or suspended supports
  • Hinged access covers for inspection/cleaning
  • CIP Cleanable equipment designs and accessories
  • VFD control for metering and weighing applications
  • ATEX Rated components for hazardous areas
  • Sanitary designs to USDA / 3A / EHEDG standards are Technopak’s specialty
