STARTING OPERATION

In the function of the machine 4 different phases can be distinguished which take place in sequence after
closing the lid. Now the machine starts its operation :
Suction phase : At the beginning of the operating cycle the pump creates the vacuum by
sucking the air from the chamber and from the bag containing the food to be preserved.
Gas injection phase (only for machines preset with gas injection device) : Inert gas is
injected in the bag by means of a nozzle placed right at the opening of the bag itself (it is
therefore important to make sure that the bag slips well into the nozzle placed in the back of
the sealing bar).
Sealing phase (sealing of the bag containing the food to be packaged) : the sealing bar has
one sealing strips for the airtight seal of the bag. Depending on the thickness of the bags
used, the sealing temperature has to be increased or decreased.
Air intake phase : Air re-enters the chamber bringing again the atmospheric pressure
conditions in the chamber. A valve allows the air intake into the chamber.
