Automatic Vacuum Capping Machine for glass jar
NP-VC Automatic Vacuum Capping Machine
Shanghai Npack is as one of the China premier manufacturer of the Automatic Twist-off Cap Vacuum Capping machine, the vacuum capper is mostly for glass jar and glass bottle,serving an array of industry like Food, Beverages, and Pickle Manufacturing Units. This innovative machine specializes in vacuum capping for bottles with lug or twist-off caps, it is also adaptable for those requiring or not requiring vacuum sealing.
It’s important to note that vacuum capping is suitable only for rigid containers like glass; attempting this process with plastic or thin metal containers can cause deformation, compromising the seal. Some variations of lug caps, such as lugless vacuum closures, use an elastomeric lining that extends up the cap’s sidewalls and forms threads when softened by steam, making them easy for consumers to open and reseal.
- This machine is engineered for the vacuuming and capping of glass bottles, utilizing a vacuum pump.
- It is versatile, accommodating various types of three or four screw metal caps, making it suitable for a wide range of applications.
- Equipped with frequency-conversion technology, the machine offers adjustable speed settings to suit different production needs.
- Designed for flexibility, it enables easy changeover between different bottle types without the necessity for swapping out components.
- The operation is streamlined through a PLC and a touch screen Human-Machine Interface (HMI), enhancing user control and interaction.
- Constructed from high-quality 304SS Food grade material for the main parts , it guarantees durability and longevity in demanding environments.
- Ideal for sealing glass bottles of various shapes and sizes, the vacuum capping machine automates the transport of bottles and caps to the vacuum chamber, where a vacuum is applied before securely tightening the cap.

How is an internal vacuum created during the capping process?
Operationally, the Automatic Twist-off Cap Vacuum Lug Capping machine works by reducing the air pressure inside the bottle using a rapid steam injection method, ensuring the cap is tightly secured. It then creates a vacuum by applying cold water over the bottle. An elastomeric lining within the cap seals any gaps between the cap and bottle neck as the internal vacuum pulls them tightly together. This internal vacuum is achieved by filling the container with a hot product or by injecting steam just prior to capping; as the steam condenses inside, it creates a nearly perfect vacuum, locking in freshness and preserving product quality.
