Theoretical packaging machine output:

Theoretical packaging machine output (Q_est) according to DIN 8743 will be,

using the above mentioned pump and machine, app. 6 - 7 cycles/min.

 

This specification is valid with an end-vacuum of app. 10 mbar, without

product and with app. 60 mm deep packages.

 

If the end vacuum can be reached, finally depends on the consistency of the

packed product and the applied packaging films. For example, the products

oxygen content, humidity and temperature and the films thickness.

 

Gas-flushing:

The adaptations for gas-flushing are not suitable for oxygen (O2) flushing

with a volumetric concentration over 21 %. When gas-flushing with a

volumetric concentration over 21 % oxygen a specially adapted gas-flushing

system has to be applied with special explosion proofed pumps, special

fitting materials etc.
