ABSTRACT:
A machine and method for filling bags with liquid through spouts attached to the bags, wherein a piston within a filling head that operates to control flow of the liquid from the filling head is also extended out of the filling head and into the spout, after the bag is filled, in order to push remaining material from the spout and through is bottom opening into the bag. The spout bottom opening is then closed, after which any remaining material adhering to the walls inside the spout and surfaces of the filling head are cleaned by forming a chamber between them through which a cleaning fluid is passed. This machine and method are particularly useful when filling bags with highly viscous and/or sticky liquids, such as thick food products. They avoid a result of having either to distribute messy bags of product with material remaining adhered to the outside of the spout and/or bag, or to first remove this material by an additional cleaning step.
