ABSTRACT:
The present invention relates to a bag filler apparatus (20) for filling bags (105) with a powdered product, the bags (105) commonly having side walls interconnecting an open top portion and a closed bottom portion. The bag filler apparatus (20) includes a support framework (78) supporting a surge hopper (28) and a scale hopper (60) interconnected so as to provide a path for the flow of the powdered product from the surge hopper (28) to the scale hopper (60). A feed auger (30) is provided for conveying the powdered product to the surge hopper (28) while a butterfly valve (66) controls the flow of the powdered product into the scale hopper (60) from the surge hopper (28). The scale hopper (60) is provided with weight sensitive elements (76) for sensing the weight of the powdered product in the scale hopper (60). A butterfly valve (86) and a fill chute (98) provide for discharge of the powdered product from the scale hopper (60). A fill chute adaptor (104) circumferentially surrounds the fill chute (98) so as to define an annular space (106) wherein a partial vacuum condition is created during the bag filling process such that the bag filling operation is essentially dust free. In addition, the partial vacuum condition in the annular space (106) retains the bag (105) on the fill chute adaptor (104) when empty and facilitates retention during the actual filling process.
