A product tank for a dual stream filling system is disclosed wherein the product tank has two chambers for containing different products that will be mixed within a carton during the filling process. The primary product in the primary chamber of the product tank may cool the secondary product in the secondary chamber. If the primary product is skim milk and the secondary product is cream, then products such as skim milk, one percent milk, two percent milk, four percent milk and cream may produced from the primary and secondary products. A filling complex is also disclosed wherein two product tanks are integrated with a filling system to fill cartons on two lines.

Dual chamber product tank for dual stream filling system

A dual-stream filling system is used in a packaging machine to introduce at least two flowable materials into a plastic bottle. The dual-stream filling system defines a material flow path therethrough. The system includes a primary filling tube having an inlet end and a discharge end and defining a primary filling tube internal flow region. A secondary filling tube has an inlet end and an outlet end and defines a secondary filling tube internal flow region. The secondary filling tube is positioned at least in part within the primary filling tube internal flow region, penetrating the primary filling tube through the first opening. The dual-stream fill system includes a valve plug that includes a portion that is movable relative to the secondary filling tube between an opened state wherein flow communication is established between the internal flow regions of the primary and secondary filling tubes and a closed state wherein flow communication is terminated between the internal flow regions of the primary and secondary filling tubes. An actuator is provided for moving the valve plug portion between the opened and closed positions. The actuator is disposed fully external of the secondary filling tube flow region.
