Four elements of modified atmosphere packaging to achieve a good shelf life
Under the premise of controllable packaging materials and controllable cold chain, the control of gas concentration in the packaging in production is particularly critical. ① Is the packaging machine can completely replace the original air during the vacuum replacement process? ② Is it filled with air? Whether the proportion of modified atmosphere fresh-keeping gas is accurate.
Fresh meat, clean vegetables, fruits and vegetables - it is imperative to monitor whether the filling ratio of oxygen, carbon dioxide and nitrogen is accurate.
Cheese, lo-mei cooked food - we must not only monitor the concentration of CO2, but also control the residual oxygen content in the packaged product.
WITT monitoring
When our modified atmosphere packaging products encountered a good market opportunity and embarked on the road of mass production, whether it was due to the vacuum replacement of the packaging machine or any leak in the gas distribution device, the gas ratio of the entire batch of finished products was incorrect, and Affecting product shelf life, facing losses such as returns, recalls, etc., I think every company does not want to meet.
Of course, many of our customers already have the means of presciently configuring sampling detection of headspace gas, so if we achieve 100% control, will it be more able to sleep soundly?
The German WITT analyzer means that every package is tested, faster and more efficient than manual testing. If something goes wrong, production stops immediately and automatically, without wasting any product, helping to avoid recalls or repackaging of entire batches. For manufacturers who use tray packaging, the online analyzer can monitor in real time whether the vacuum tray packaging is filled with the correct fresh-keeping gas.
How does it work?
The first step is to select the correct program to ensure the correct alarm level is set. If WITT is detected, then the correct gas ratio must also be set first.
In the second step, while the packer is running, the residual oxygen content (and optionally the carbon dioxide level) is measured each cycle, and the analyzer draws a sample gas directly from the packer tray mold and gives an average measurement of the gas content.
If the oxygen or carbon dioxide levels are approaching the limit, the operator will be notified; if the limit is exceeded, the packaging machine will stop.
The optional buffer tank measurement provides better control by checking the gas composition in the buffer tank before flushing the package.
The headspace analysis system specially designed for modified atmosphere packaging machines, I believe that with such a killer configuration, whether it is a food packaging company or a modified atmosphere packaging machinery manufacturer, there is no reason to reject it.
