Filling

 
 
Aseptic Filling Lines for Dairy & Sensitive Beverages
Dairy is one of the first foods we grow up with, and for many it remains a trusted, valuable staple through adolescence and into adulthood. Since milk and dairy products play such a central role in everyday life, they deserve to be produced and handled with the utmost care.

Filling sensitive beverages is a careful balancing act. Absolute consumer safety must be guaranteed at every step, yet many beverages are highly reactive to preservatives or thermal stress. Aseptic filling strikes this critical balance — but only when underpinned by deep microbiological expertise and proven, field-tested technology.

Our aseptic filling lines are built to deliver on both requirements. They support wet or dry sterilization to match specific product needs, feature fillers with load cell or flow meter metering, and are available in both high and low output ranges. This outstanding flexibility and reliability makes them the preferred choice of bottlers worldwide, delivering consistent premium results across a wide spectrum of operating conditions.

Our filling systems:
- Ensure precise, accurate fill quantities
- Deliver the highest standards of microbiological safety
- Handle products gently to preserve flavor and sensory quality
- Require minimal cleaning time and energy input

Labeling

 
 
Hot Glue Rotary Labeling Machine
This rotary hot glue labeling machine is purpose-built for wrap-around labeling of bottled drinking water, juice, carbonated soft drinks and other beverage products. Rated throughput ranges from 20,000 to 60,000 bottles per hour (BPH) for 500ml containers, with compatibility for bottle sizes up to 2,000ml.
 
Reduced Glue Consumption
Built for pre-cut paper and/or plastic wrap-around labels, the labeling unit uses an industrial-grade hot melt applicator with Nordson technology, delivering substantial glue savings over conventional systems.
The labeling process follows a controlled sequence: the system applies dots or strips of hot glue to the container to pick the label from the magazine; an applicator then adds adhesive to the label’s final vertical edge, before a smoothing mechanism completes the bond for a clean, secure finish.

Fast Changeover & Easy Maintenance
Format changeovers require no specialized tools, making product switches fast and straightforward. Adjustments and recipe updates can be made directly via the HMI interface. The highly ergonomic design gives easy access to all machine components, cutting maintenance time significantly.

Flexible Line Configuration
The labeler can be set up in multiple configurations to match available floor space and required production speeds, including options for dual glue pumps. It supports both in-line and parallel line layouts to fit different production floor plans.

High-Capacity Continuous Operation
It reaches speeds of up to 60,000 applications per hour, supporting non-stop production runs. The intuitive operating design also makes it extremely easy for line operators to run and monitor.

Shrink Film Wrapping Machine
This fully automatic shrink film wrapping machine is designed for secondary packaging of bottled drinking water, juice, carbonated soft drinks, dairy products and similar beverage lines. It delivers a rated output of 20 to 80 packs per minute, with end-to-end automated operation covering bottle infeed and arranging, film wrapping, seal-and-cut, heat shrinking, and cooling & forming.

Consistent High-Strength Sealing
A constant-temperature heat sealing system delivers uniform, secure seal integrity across every pack. A rapid seal cooling structure maintains high seal strength even under sustained high-speed production conditions.

Precise Control & Low Film Waste
Equipped with a PLC control system, the machine delivers stable, reliable performance across all operating speeds. Original imported guide rod cylinders ensure accurate actuation and long service life. An inductive switch controls the film feed system to precisely adjust film length and minimize material waste, while the entire conveyor runs on variable frequency drives for smooth, steady transfer.

Uniform Heat Shrink Tunnel
The dedicated heat shrink tunnel houses two sets of centrifugal hot air circulation systems for even heat distribution across the entire chamber, resulting in a clean, consistent and secure shrink finish. Three layers of thermal insulation provide strong heat retention, supporting fast warm-up times and reduced energy consumption.

Enhanced Cooling & Fast Changeover
An enhanced cooling and shaping section rapidly solidifies the shrink film into a high-strength pack structure, making packs immediately ready for storage and downstream transportation. Switching between different pack configurations and bottle sizes is simple and requires minimal retooling, enabling one machine to handle multiple packaging requirements.
 
 

Palletizer

 
 
Palletizing Robots
These compact, high-throughput palletizing robots bring full automation to end-of-line palletizing systems. Designed for bottled drinking water, juice, carbonated soft drinks and other beverage lines, they deliver a rated output of up to 520 layers per hour. Multiple models are available to match specific workpiece needs, with payload options spanning 110kg, 140kg, 185kg, 315kg, 500kg and 700kg.
