Vacuum Packaging

The food industry relies primarily on vacuum packaging to maximize the shelf life and freshness of products.Vacuum packaging prevents the growth of oxygen-dependent bacteria and the associated oxidation, helping to preserve the freshness, flavor, and quality of food for longer periods.

Suitable vacuum pumps remove air from the packaging bags, thereby extracting most of the oxygen. Once the required vacuum level is achieved, the bags are hermetically sealed.

Requirements

The proper functioning of the packaging machine must be checked regularly. Quality, freshness, nutrients and taste can only be fully preserved if the vacuum is sufficient. Even minor deviations in the packaging technology can affect product quality.

Compact vacuum meters offer an efficient solution for fast and reliable monitoring of pressure levels in packaging and production processes. If required, they can be sealed directly into the packaging. This allows manufacturers to draw conclusions about the achieved final pressure and the packaging’s seal integrity, as well as monitor transportation parameters.

Suitable Products

VD81: A battery-operated VD81 vacuum meter is inserted into the packing machine at set intervals and vacuum-sealed and shrink-wrapped in place of the product. During this process it stores the minimum pressure reached. Once the device has been removed from the packaging, the minimum pressure can be read-out and checked.

VD810: The robust piezo vacuum meter with extended functions and features measures absolute and relative pressure in the rough vacuum range from 2000 to 1 mbar (abs.) and -1060 to +1200 mbar (rel.), regardless of the gas type. The device's membrane keypad enables convenient, menu-driven user guidance. An internal data logger stores several separate measurement series with their RTC data. Welded into the packaging, an online measurement can be started via Bluetooth®.
