This liquid filling line handles oyster sauce, ketchup, chili sauce, barbecue sauce, salad dressing, tomato sauce, honey, syrup, cooking sauce and other viscous or semi-viscous liquids. The line cleans empty bottles before filling, meters sauce through four piston filling heads, feeds and tightens caps, applies shrink sleeves, shrinks the film around the bottle, and connects directly with case sealing at the end of the line.
