ABSTRACT:
A filling nozzle for use in filling a valve bag eliminates sifting of product during the filling process. The nozzle has an air conduit that supplies high pressure air to clear the nozzle of product after a bag has been filled. An air conduit for low pressure air is provided to introduce air between the nozzle and the bag's valve sleeve for suspending any particles remaining in the valve sleeve after the bag has been filled. A vacuum suction passage is provided to withdraw the suspended particles from the valve sleeve. The nozzle can be used in conjunction with a slitted valve sleeve. The discharge end of the nozzle directs the flow of product downwardly through the slit in the valve sleeve and into the interior of the bag.
