The Vacuum Cap vacuum capper is an advanced solution for vacuum capping glass jars with Twist-Off metal caps, designed to preserve food in glass jars that are packaged at room temperature and cannot undergo thermal treatments such as pasteurization or sterilization.
Structure and Materials The Vacuum Cap vacuum capper is constructed with high-quality materials to ensure durability and reliability. The base is made of AISI 304 stainless steel, known for its corrosion resistance and ease of cleaning. The compact base structure, measuring 600×600 mm, makes it suitable for various work environments, while its weight of 35 kg ensures stability during the capping operation.
Capping System This capper utilizes an advanced mechanism to create a vacuum in the headspace of the jar, reducing oxidation times and extending product shelf life. The torque control system ensures a secure and uniform sealing of the Twist-Off caps. Additionally, the Vacuum Cap allows customizable adjustments of the vertical pressure on the cap and the vacuum level before screwing, offering great operational flexibility.
Operation The closing process is simple and intuitive: the jar is manually placed into a sliding PVC cylinder, with the cap positioned on the neck of the jar. By simultaneously pressing the two buttons on the sides of the base, the capping head lowers, creates a vacuum, and seals the lid in one smooth motion. This ergonomic design ensures a safe and effortless operation.
Versatility and Format Change The Vacuum Cap capper is extremely versatile, capable of working with jars and bottles of various shapes (round, square, hexagonal, conical, oval, and octagonal) and sizes of Twist-Off caps (Standard and DEEP) without the need to modify the capping spindle. Each jar format is associated with a PVC cylinder that centers the container and brings it to the correct height, eliminating the need for mechanical adjustments during format changes.
Pneumatic Motor Performance The modular stainless steel lamellar pneumatic motor, combined with a mechanical compensation unit for the capping head, offers excellent performance. It operates with air pressure ranging from 3 to 5 bar, with a power of 0.15 HP at 3 bar and 0.35 HP at 5 bar. The rotation speed varies from 900 RPM at 3 bar to 500 RPM at 5 bar, while the maximum torque reaches 2.3 Nm at 3 bar and 4.8 Nm at 5 bar.
Power Requirements The Vacuum Cap capper requires a compressed air supply at 6 bar and a single-phase electrical current at 220V. It is essential to ensure a sufficient free air flow for the capper’s consumption as specified in the technical data.
Container Dimensions and Cap Sizes The capper can handle jars with a maximum diameter of 100 mm and a maximum height of 140 mm. It is compatible with Twist-Off caps ranging from 38 to 82 mm in size.
The Vacuum Cap vacuum capper is the perfect choice for those seeking a reliable, versatile, and high-quality solution for food preservation, ensuring secure sealing and extending the shelf life of packaged products.
