4.2 Description of the Packaging Process/Machine Functions
This section provides an overview of the packaging process and available machine functions.
4.2.1 Packaging Process/Machine Functions
This section describes the packaging process and the machine functions. See Operation on page
19 for the realization of the specific steps of the procedure.
Step
Process phase
Operation
1.
Preparation
The operator puts the product in a vacuum bag and places it
on the work surface with the opening on the sealing position.
2.
Applying vacuum
The vacuum process is initiated by closing the lid.
During the cycle, the air will be removed from the chamber
until the set vacuum percentage or time has been reached.
3.
Sealing
The sealing bars are pressed against the vacuum bag and
melt the bag closed.
During the sealing process, the material of the vacuum bag
is heated and pressed together to create a hermetic seal.
The programming of this function takes place in seconds.
Optionally, the second sealing wire can be replaced by a cut-
off wire. The purpose of the cut-off wire is to remove the ex-
cess foil from the remaining flap.
4.
Decompressing
The vacuum is removed from the vacuum chamber by letting
air into the chamber.
5.
Opening the vacu-
um chamber
The lid opens.
6.
Removing the
product
The operator can remove the packaged product from the
work surface.

Operation
Cleaning of the
oil pump
The pump cleaning programme ensures that the pump is thor-
oughly rinsed. During the programme, the pump and oil reach
the operating temperature, so the oil and moisture are separated
and any contamination is filtered. The high temperature causes
any moisture in the pump to evaporate, thus minimising the risk
of corrosion.
