Filling and packaging line for the food industry

automatic

Overview
We supply a complete automatic liquid filling line designed for sauces, jams, chili sauce, ketchup, salad dressings, condiment pastes and other non-carbonated food liquids. The line performs empty-bottle feeding, piston dosing, capping, labeling and finished-bottle accumulation. It handles glass and plastic bottles as well as free-flowing liquids and viscous pastes. Units are supplied for international markets and installed in multiple countries.

What Products This Filling Line Can Handle

• High viscosity pastes & sauces: chili sauce, beef sauce, broad bean paste, ketchup/tomato sauce, BBQ sauce, mayonnaise, honey, peanut butter, condiment paste
• Medium viscosity sauces & dressings: salad dressing, pasta sauce, fruit jam, marmalade
• Low viscosity free-flowing liquids: cooking oil, fruit juice, vinegar, soy sauce, syrup and other non-carbonated food liquids

Complete Liquid Filling Line: Working Process

• Bottle Feeding: Bottle unscrambler sorts and orients empty bottles and feeds them steadily to the conveyor.
• Product Filling: Piston filler doses the preset volume of sauce, jam or paste into each bottle with repeatable accuracy.
• Bottle Capping: Automatic capping unit supplies caps, places them and tightens to the required torque.
• Bottle Labeling: Label applicator applies self-adhesive labels to the bottle body according to position and bottle shape.
• Bottle Collection: Accumulation turntable or conveyor collects finished bottles for packing or downstream processing.

Main Equipment in the Sauce Filling Line

• Bottle Unscrambler: Sorts and feeds empty bottles automatically
• Piston Liquid Filling Machine: Precise volumetric filling for liquids and thick pastes
• Automatic Capping Machine: Picks, places and tightens caps
• Bottle Labeling Machine: Applies self-adhesive labels to finished bottles
• Bottle Accumulation Turntable: Collects finished bottles for packing

Features of the Automatic Liquid Filling Machine

• Consistent & precise filling: Piston filling provides accurate dosing for sauces, jams and pastes during long production runs.
• Hygienic food-grade construction: Product-contact parts made from food-grade 304 stainless steel for hygiene and cleaning.
• Intuitive control: PLC touch-screen control to set filling volume, line speed and product recipes.
• Custom factory layout: Conveyor and machine arrangement can be tailored to available floor space for easy operation and maintenance.
• Modular & expandable: Modular design allows capacity upgrades and integration with upstream/downstream equipment.

Benefits of the Automated Bottle Filling Machine

• Lower operational costs: Automates manual filling and reduces labour and product waste from overfills.
• Improved plant efficiency: Integrates filling, capping and labeling to reduce bottlenecks and increase throughput.
• Handles thick & sticky pastes: Designed for viscous sauces and pastes that are not manageable by gravity fillers.
• Reliable daily operation: Synchronized machine speeds minimise jams and stops.
• Future-proof investment: Expandable modules reduce the need to replace the entire line when capacity grows.

FAQs (selected)

• Q: Is this filling line fully automatic? Yes. The line can run fully automatically for bottle sorting, filling, capping and labeling; operators replenish bottles, caps and product.
• Q: Can it handle thick products like chili sauce or jam? Yes. The piston filler is suitable for high-viscosity products such as chili sauce, jam, ketchup and condiment pastes.
• Q: Can the machine handle products with particles? Depends on particle size and shape. Small seeds or pieces may require custom valves, nozzles, hopper or filling-path modifications.
• Q: Can it handle different bottle sizes? Yes. Adjustable guides, height settings and volume parameters accommodate various bottle dimensions within the specified filling range.
• Q: What capacity can the line reach? Standard output is 10–80 bottles per minute, depending on fill volume, viscosity, number of filler heads and cap type.
