Bulk Bag Unloader Case History 3S-1235

Major food manufacturer contacted us after reviewing our website.  They required three dust tight bulk bag unloaders to replace three old, outdated units, which were a constant dust and flow problem.  We bid to the client’s specification.   Hapman and Flexicon were the two other bidders. 

  • “I liked your overall design best.  You offer better containment than your competitors.”  
  • “Your unit is very heavy duty.  I really like your heavy duty massaging paddles.”  
  • “You offered a nice, clean design to collapse the empty bulk bags.”  
  • “You were price competitive.”

Client selected 3Sigma specifically because:

  • Discharge of this difficult product – Cocoa Powder
  • Dust tight design
  • Food grade – 316SS, welds continuous, ground smooth, contact surfaces to be #4 finish or better
  • Guaranteed flow of product through specialty discharge chutes to downstream equipment.
  • Fit within the existing space

Customer Needs:



  • We provided our Massage-It™ bulk bag unloader to ensure discharge of this difficult to flow product.
  • The system included our oversized Contain-It™ chamber that contains ALL spills, WHEN they occur.
  • We provided our Clamp-It™ seal to positively seal the bag outlet spout to the Tube-It™ discharge tube.
  • We provided our Close-It™ valve which fully stops the flow of material through the bag upon demand.
  • We provided our Collapse-It™ system which evacuates most dust from the bag and collapses it upon completion of discharge.
  • We provided custom Tube-It™ discharge tubes, to connect to downstream equipment, and included an aeration system to ensure product flow.
  • The control system and solenoid valves are mounted and plumbed, requiring one 111/1/60 connection and one air line connection.
