5. dESCRIPtION OF thE maChINE aNd ItS FUNCtIONS

The Friulmed chamber vacuum packing machines are used to vacuum pack products inside special bags or
containers. For this purpose, the vacuum bag containing the product is placed inside the vacuum chamber. Once
the lid is closed the vacuum pump is activated, which draws the air from the chamber. After a few seconds, the
depression created inside the chamber allows the lid to remain closed. Once the vacuum is complete, the bag
is hermetically sealed by means of a sealing bar. Subsequently, the air enters the chamber once again, thereby
allowing the lid to be opened automatically. The packed product can then be removed from the chamber.
Another method of vacuum packing products consists in using special rigid containers, inside which the vacu-
um is created by using a device that connects the machine to the container. Space permitting, the container is
placed directly inside the chamber. The air is drawn from the container through a special check valve, which is
closed once the vacuum is complete.
Certain special "embossed" bags allow the vacuum to be cre-
ated outside the vacuum chamber, thereby allowing products
with dimensions larger than those of the vacuum chamber
to be packed.
