6.1.4. Execution
Arrange the maximum number of shelves (13) the hood (14) may
accommodate according to the sizes of the product to be packed.
Place the envelope inside the hood and on the sealing bar in a way as
linear as possible.
Try to prevent the envelope from wrinkling. Wrinkles might negatively
affect the hermetic seal formed by sealing. Envelopes shall be at least 2
cm beyond the sealing.
If the "GAS" function is on, the envelope must be positioned with the strip
open on the gas nozzle on one side of the sealing bar.
Close the upper Plexiglas cover.
Model MV26 X:
the packaging cycle starts when the cover is closed.
Models MV31 X and MV35 X:
The packaging cycle is sub-divided into four phases:
1.
Suction phase during which all the air contained inside the bell and
the bag is sucked.
2.
Gas injection phase (if the machine is equipped with a gas plant).
3.
Sealing phase during which the packet is sealed.
4.
Air re-enter phase and subsequent opening of the cover.
The hood will reach its atmospheric pressure and the upper cover will
open again.
Machine is ready for a new packing cycle.
If you press the Stop button (8), the machine will immediately stop sucking and automatically start sealing
the pouch. This function will be used to pack liquid and hot products which may start boiling during the
vacuum cycle.
