Abstract
According to a preferred embodiment, a machine for filling containers, such flexible plastic bags, with fluid product, such a liquid food product, uses two container fill nozzles that each has a product supply system. While one of the nozzles is being used to fill containers that are being moved through the machine, the other nozzle and its product supply system is being cleaned. For the cleaning, at least one receptacle is provided to receive a nozzle being cleaned. Any product remaining in the delivery system and nozzle is flushed out through the receptacle in which the nozzle is inserted, and those portions cleaned. Fresh product is then loaded back into the delivery system and dispensed through the nozzle into the containers. This system and these operating techniques allow the product to be changed frequently without having to suffer a significant down time of the filling machine for cleaning.
