Bottle Line

Bottling Line

Professional Packaging Equipment Supplier

1. Product Overview

The bottling line is a fully automated packaging production line integrating three major processes: bottle rinsing (washing), filling, and capping. It is primarily applied in PET and glass bottle packaging for beverages, drinking water, alcoholic drinks, condiments, and other liquid products. The bottling line employs an advanced PLC programmable control system and touchscreen HMI to achieve fully automated continuous production from empty bottle input to finished product output. It features compact structure, small footprint, low energy consumption, and high production efficiency. Through rational process layout and precise mechanical coordination, the three critical processes of rinsing, filling, and capping are seamlessly connected, effectively avoiding secondary contamination risks and ensuring product hygiene safety and packaging quality. Based on filling principles, bottling lines are classified into gravity filling, isobaric filling, vacuum filling, and flow meter filling types to accommodate various material characteristics and filling accuracy requirements.

2. Working Principle

The working principle of the bottling line is divided into three main stages: First, bottle rinsing — empty bottles are conveyed into the rinser, where bottle clamping mechanisms invert the bottles, and sterile water or ozone water is sprayed through nozzles to wash the inner walls multiple times (typically 2~4 water rinses + 1~2 purified water rinses). Rinse water is discharged through independent piping to prevent cross-contamination. After rinsing, the bottle clamps return bottles to upright position and transfer them to the filling station. Second, filling — filling valves perform quantitative filling based on the filling principle: gravity filling relies on liquid level differential for natural flow to the set level; isobaric filling first charges CO2 into the bottle to establish equal pressure before liquid flows in by gravity; vacuum filling draws liquid in by creating a pressure differential through vacuum; flow meter filling precisely controls filling volume through electromagnetic flow meters. Third, capping — filled bottles enter the capper, where a cap sorter aligns and feeds caps to the capping station, and capping heads descend to grip caps and tighten them onto bottle mouths at the set torque. The entire three-in-one process is synchronized by a single PLC system, with precise transfer between stations via star wheels and guide rails.

6. Typical Application Fields

Drinking Water Industry: Purified water and mineral water in PET bottles — the largest application area for bottling lines. Requires high-speed filling, precise liquid level, and hygiene safety using gravity filling.

Carbonated Beverage Industry: Cola, soda, and other carbonated drinks in PET bottles. Uses isobaric filling to prevent CO2 loss and foaming during filling.

Juice & Tea Beverage Industry: Hot filling (85~95°C) or aseptic cold filling for juices, teas, and functional beverages. Aseptic filling requires a sterile filling room.

Alcoholic Beverage Industry: Spirits, wine, and rice wine in glass bottles. Requires high filling precision with no dripping or foaming, typically using vacuum or isobaric filling.

Condiment Industry: Soy sauce, vinegar, and cooking oil bottling. Uses flow meter filling for precise volumetric measurement.
