2.4 Safety when vacuuming
...
DANGER
Vacuums kill living organisms! Do not vacuum-pack any living organisms and also ensure that
no living organisms are vacuum-packed by unauthorized persons or children!
Vacuum packaging systems use a vacuum pump to remove air from a hermetically sealed vacuum
chamber in which the product and the packaging has been placed. Therefore, access is not possible
during the sealing process. External air has to flow into the chamber before the two parts of the sealing
tool can be opened.
Never try to open the tool with force!
The vacuum is used to extract the air in the packaging. According to the laws of thermalphysics, mois-
ture in the air starts to evaporate at a relatively low vacuum. This means that products which contain a
large amount of uncombined moisture can be affected.
The vacuum pump has the reverse effect, like a compressor. Dust particles, but also moisture, are en-
trained by the vacuum current and can reach the vacuum pump unhindered. If products for which this
process can occur are to be packaged, it is recommended to install a dust or moisture separator in front
of the vacuum pump.
This especially applies for products which have a high sugar or starch content (sauces and breadcrumb
coating), since entrained particles become incrusted in valves and small bore holes in the tool and on
the lamellas of the vacuum pump where they crystallize or agglutinate. And since these locations can
hardly be cleaned, functioning of the entire system can be significantly affected if a filter and separator
are not installed.
It is also hazardous to package flammable or explosive products (icing sugar or dextrose, but also spray
or perfume bottles), since entrained parts or particles can react accordingly.
...
DANGER
Spray bottles with a specified internal pressure should not be vacuum packed, since a reduc-
tion of the external pressure causes the high internal pressure to explode.
The standard version of the Vacuum Packaging Machine VC999 K7 is equipped with a vacuum pump
but without a filter or separator, if not ordered with the respective equipment.
2.4.1 Safety precautions and equipment
The following safety precautions and equipment are designed to ensure your safety:
•
EMERGENCY STOP button on both sides of the cockpit
If an emergency or hazardous situation arises, use the EMERGENCY STOP buttons to immediately
stop the Vacuum Packaging Machine and to de-energize any hazardous components. Release of
the EMERGENCY STOP button does not automatically restart the machine. The machine has to be
actively re-started.
