What other machines does the automatic filling line include

An automatic filling line is a packaging system that consists of multiple specialized machines, which can realize automatic processes of bottle filling, plugging, capping, sealing, and labeling. Using automatic filling lines can help to improve production speed and reduce errors that may be caused by labor.

Filling Machines

The filling machine is one of the main parts of any automatic filling line. It precisely measures and dispenses products into containers. Some fillers use a piston filling system, which is ideal for viscous products. Others, like peristaltic fillers, work best with free-flowing liquids like oils or beverages. Reliable filling machines ensure exact amounts every time, reducing waste and saving costs.

• Filling Accuracy: High-precision piston fillers achieve a ±1% accuracy rate, ensuring consistent product volume in each container.
• Speed and Capacity: Some automatic filling machines like ZS-YT4T-4PX operate at 30-50 bottles per minute, which varies with different liquid types and container sizes.
• Container Compatibility: Different filling ranges can be customized according to the needs of the industry.

Capping Machines

After filling, capping machines can seal the containers using different types of caps, for example, crimp-type caps, screw-on caps, and push-type caps. A reliable capping machine can prevent leakage and ensure product freshness. A capping machine can usually work with a cap feeding system to speed up production.

• Cap Types Supported: Screw caps, press-on caps, dropper caps, flip-tops, and corks, depending on the product type.
• Capping Speed: Automated capping machines can cap 40 bottles/min, significantly increasing production efficiency.
• Bottle Size: Capping Machines can be customized to suit different diameters and heights of containers and caps.

Labeling Machines 

Labeling is vital for brand recognition and product safety. Automatic labeling machines apply labels quickly and precisely. Clear labeling enhances brand image and helps meet regulatory requirements, providing customers with necessary information displayed on the packaging.

• Labeling Accuracy: Labeling machines are designed to apply labels with high precision, ensuring proper alignment and appearance.
• Label Size Compatibility: These machines support various label sizes, adaptable to different container shapes and sizes.
• Speed Efficiency: High-speed labelers can process numerous bottles per minute, maintaining a smooth workflow and consistency.

How Does an Automatic Filling Line Operate?

Understanding how an automatic filling line operates helps businesses appreciate its efficiency. Each machine within the line performs a specific task to ensure continuous operations.

• Bottle unscramblers ensure continuous feeding into the production line, maintaining a steady flow of containers.
• Air rinsing or water-flushing systems remove dust particles, ensuring cleanliness before filling.
• Precision filling machines dispense product at high accuracy rates, ensuring consistent volume.
• Speed varies by viscosity:

o Thin Liquids (e.g., Food Colors)

o Medium-Thick Liquids (e.g., Lotions, Syrups)

o Thick Liquid (e.g., Heavy Creams, Pastes, and Jams)

Throughout the process, inspection systems check for defects, verifying proper fill levels, secure caps, and correct labels. Finally, completed containers leave the automatic filling line ready for distribution or sale.

Recommended Automatic Filling Lines by ZONESUN

Businesses looking for reliable equipment find high-quality options at ZONESUN. Two outstanding automatic filling line machines include:

Automatic Sauce Bottle Filling Line

ZONESUN automatic sauce filling line can be used for packing food paste into bottles, tightening metal lug caps, and sticking labels. It can be used for different pastes, such as jam, chili sauce, honey, ketchup, and so on. The filling line uses a piston filling system, the filling range can be customized. It is ideal for enterprises that want to speed up their production.

• Bottle Size: It supports customized applicable bottle sizes and customized bottle cap diameters, allowing the filling of bottles of different sizes.
• Multiple Roles: It supports filling, capping, and labeling roller ball bottles, making it ideal for small-scale production.
• 3 Types of Labeling: single-side, double-side, and wrap-around labeling.

Automatic Liquor Filling Line

ZONESUN automatic liquor filling line performs automatic functions of bottle rinsing, drying, filling, corking, shrinking, and labeling. It can handle different kinds of liquor, including gin, sake, whiskey, wine, liqueur, etc. ZONESUN can customize the automatic filling line according to your production requirements.

Take ZS-YT4T-4PX as an example:

• Filling Volume Range: Supports filling volumes from 10ml to 1000ml, adaptable to various types of
• Filling Speed & Accuracy: It handles 30-50 bottles per minute, depending on the bottle size and product viscosity. It also uses servo piston-based filling for ±1% accuracy, ensuring precise dispensing without overflow.
• Material Feeding System: The filling machine is integrated with a material feeding pump. It can supply materials into the hopper automatically. This can save labor.

An automatic filling line streamlines packaging by combining essential processes into one efficient system. Investing in automated filling lines saves businesses time and labor costs. Companies in food, beverage, cosmetics, or pharmaceutical industries benefit from reduced errors and improved productivity.
