Vacuum Devices

In restaurants there often remain already cleaned salad and vegetables which are not consumed the same day.

A vacuum packaging in bags would only be possible by using a gas flush. Otherwise this sensible food would be pressed by the vacuum.

A good alternative is the vacuum packaging in
standardized catering boxes which are put into
the refrigerator after the vacuum process.

If there is a vacuum packing machine with a big enough vacuum chamber, the box can be simply put into the machine and the vacuum is produced.
