The patented Clean-Pak II ultrasonic sealer for valve bag packers controls and contains dust throughout the entire packaging process. The Clean-Pak uses ultrasonic energy to displace product from the seal area and weld the sealable sleave. It is easily adapted to Stonepak Force Flow (air) and Jet Flow (impeller) packers. All bags are sealed in the same position they are filled. The design utilizes an inflatable filling tube collar and swirl airblast tube clean-out, in addition to an ultrasonic sealer. A positive closure is obtained even through heavily contaminated valves. To fill and close bags cleanly, dust collection is active throughout the entire cycle. The simple design minimizes wearing parts. The ultrasonic sealer is rigidly mounted to the packer frame. Accuracy is enhanced because the bag is fully closed prior to discharge to conveyor, resulting in no product spillage. The small footprint minimizes required floor space.
