WITT MAPY inline gas analysers
The WITT MAPY inline gas analysers are designed to simplify quality assurance during modified atmosphere packaging. The analysers can continuously monitor the gas composition during packaging, directly in the packaging machine. This can help to reduce costs by simultaneously optimising the amount of gas used.
The analysers allow the quality checking of the entire output of a packaging machine in real time during the packaging process. Another advantage is that any malfunctions are detected directly and can be corrected.
There are two analysers in the range: the MAPY LE for flow packing machines with continuous gas flushing, and the MAPY VAC for tray sealing and thermoforming packaging machines with intermittent gas flushing.
In the case of flow packing machines, a sample is continuously drawn from the closing form fill and seal bag by means of a lance during the introduction of the protective atmosphere, and compliance with the desired gas mixture is monitored by the MAPY LE.
The MAPY VAC analyses the inflowing protective gas directly in the sealing tool during the cycle of the packaging machine. If the adjustable limit values for O2 or CO2 are breached, MAPY VAC and LE sound an alarm or stop the packaging machine directly. The whole process takes place automatically and at maximum speed. This results in a complete and non-destructive inline quality control.
Both analysers are compact devices in hygienic stainless steel casings. The digital control system drives everything, including the communication with the gas mixing unit. The analysers can be integrated into the network via an Ethernet interface. All processes and results are stored internally and can be exported.
