How does a Chamber Vacuum Sealer work? Its Uses & Benefits

Chamber Vacuum Machines are a fantastic choice for industrial sealing because they are built to meet any high volume demands — small organisations or individuals who frequently vacuum seal will benefit from this equipment. Furthermore, because the machines are built for industrial purposes, they have a longer operational life and, as a result, last for longer, even when exposed to higher volumes. When it comes to vacuum sealer machines, there are numerous options available in the market. Although most vacuum sealer machines appear to have identical capabilities, your design will impact the final output.

What is a Chamber Vacuum Sealer?

Chamber Vacuum MachinesChamber Vacuum Sealers are designed for vacuum packaging applications requiring maximum air removal to extend shelf life. They are reliable and provide build quality. Due to their adaptability and effectiveness, Chamber Vacuum Sealers are frequently used in sous vide cuisine (an innovative cooking technique in which food is vacuum-sealed and slow-cooked in water at constant low temperatures until it’s perfectly cooked through), supermarkets, and in the commercial industry. The vacuum sealer features a transparent lid with a deep-drawn stainless steel chamber (no welded corners), providing optimal hygiene. A quick change seal bar allows for easy maintenance and reduced downtime. Furthermore, Chamber Vacuum Sealers can be equipped with various options, including gas flush for modified atmosphere packaging and vacuum level sensor to ensure that the same vacuum level is achieved every cycle.

How does a Chamber Vacuum Sealer work?

Step 1: Vacuum Extraction

Fill a vacuum bag with your goods and place the bag’s end on the seal bar. If your product is not too heavy, use the insert plates to ensure the load is accurately positioned on the seal bar and a faster vacuum cycle. When you close the lid on the machine, the pump extracts air from the vacuum chamber and oxygen from the package. The entire chamber will be vacuumed, resulting in equal pressure inside the vacuum bag and across the chamber.

When the bag sticks out of the chamber during the sealing cycle, the air inside the bag cannot escape as the surrounding pressure is reduced. If the pressure inside the bag exceeds the pressure inside the chamber, the bag will appear to swell. If the difference between the two becomes too significant, the bag will rupture, causing a mess.

Step 2: Sealing the Vacuum Bag

The bag must be sealed shut at the end of the vacuum-sealing cycle to prevent air from re-entering the bag. The sealing wires are heated to melt layers of the bag together after the sealing and contra bar are closed. The bars reopen after a couple of seconds. For various sizes and types of bags, multiple seal configurations are achievable. The valve opens when the sealing is complete and the chamber is refilled with air. Air cannot enter the bag because it is sealed tight, and atmospheric pressure causes the plastic bag to collapse securely over the product, completing the sealing cycle.

Difference between Chamber Vacuum Sealer vs Standard Vacuum Sealer

  • Vacuum sealers use a nozzle to suck the air out of a bag. Chamber Vacuum Sealers instantly pump out the air from the chamber, including the air inside the bag. This provides the item with a total airtight seal.
  • Chamber Vacuum Sealers can package liquids, unlike Standard Vacuum Sealers.
  • Chamber Vacuum Sealers are fully electric, but nozzle vacuum sealers rely on electricity and pressurised air.
  • Chamber Vacuum Sealers usually have 2-3 seal bars for multiple packaging at once, but nozzle vacuum sealers have one seal bar for individual packaging.

Chamber Vacuum Sealer Uses

  • Food (Liquid & Solid)
  • Electronics
  • Medical Tools
  • Consumer Goods

Benefits of a Chamber Vacuum Sealer

  • Extending the shelf life of perishable items is possible by removing excess air from the packaging. Food items will last longer, decreasing waste and product loss while preventing spoiling
  • Easy Liquid Packaging – These vacuum sealing systems are helpful when packaging liquids since they use pressure instead of suction to expel extra air from the package
  • Fast Packaging Speed – More goods can be packaged and sealed in a shorter time than manual packaging processes
  • Reduced Labour and Production Cost – There is minimal manual intervention because the machine handles the heavy lifting.
  • High volume capacity
  • Easy packaging for irregular shapes
