Cold Vacuum Closing CVC

CVC Cold Vacuum Closing Machine for Glass Jars

What is this machine?

The LVS Technics Cold Vacuum Closing Machine (CVC) is an automatic jar closing machine that creates a reliable vacuum seal without using steam. Instead of generating vacuum by injecting steam into the headspace of the jar, the CVC removes the air using a vacuum pump immediately before the lid is applied.

This unique closing method makes the CVC particularly suitable for products that must not come into contact with moisture during the packaging process. The machine supports a wide variety of jar and lid sizes through interchangeable size parts.

Available as a one-head or four-head version, the Cold Vacuum Closing Machine can be integrated into both stand-alone applications and complete filling and packaging lines. Optional lid feeding and lid pre-heating systems further improve automation, sealing consistency and production efficiency.

How does the Cold Vacuum Closing Machine work?

Filled jars enter the closing machine via the conveyor system.

Lids are automatically supplied using a lid feeding and sorting system. For applications where consistent compound temperature is important, the lids can first pass through an optional lid pre-heating system before reaching the closing station.

Inside the closing chamber, the jar is positioned beneath the closing head. A vacuum pump removes the air from the headspace immediately before the lid is applied. Once the required vacuum level has been achieved, the lid is securely closed.

The closed jars leave the machine and continue to the next stage of the packaging line, such as inspection, washing, drying or labelling.

Because the vacuum is created mechanically rather than by steam, the process remains dry and highly controlled throughout the entire closing cycle.
