3.2 Special packaging:
·3.2.1 Gas flushing (option):
There is an atmospheric pressure
of
1 kg/ sq. cm (14 lbs/sq. inch) upon products when
fully evacuated. Products which can be damaged
by
high pressure must be
packaged
with a partial vacuum, or the pressure must be counterbalance
by
inflating the bag with
gas (nitrogen or carbon dioxide) before sealing after evacuation.
For gas flushing, the bags are placed on the sealing bars, the open end placed over
the gas nozzles mounted alongside the sealing bar. After evacuation, the vacuum
valve closes and the gas valve opens. Gas time (sec.) can be set in the program
menu.
The necessary gas tank and pressure valve mounted on tank is not supplied, The
pressure
of

for
gas connection when gas flush
option is ordered.
