VACUUM PACKAGING OF LIQUID OR SEMILIQUID PRODUCTS
By means of the bell-lid vacuum packaging machines produced by us it is possible to vacuum package liquid
or semiliquid products (soups, sauces, etc..) thus increasing their duration time and keeping hygiene and
taste unchanged.
Fill the bag up to 50% of its capacity only, and keep a difference of level between the bag edge and the
sealing bar (by removing the internal shelves) when positioning the bag in the machine.
-
Vacuum cycles are set as described in the chapter USE OF THE MACHINE.
-
Since it is not possible to compress liquids, they do not need a modified environment during packaging,
that is with inert gas addition.
-
All the vacuum packaged products can be stored one upon another in the cold room.
NOTE
a) Reset the line by pressing the luminous button (fig. 7 page 8) to "OFF" position thus switching it off,
each time work processing with the machine is completed.
b) Check the direction of rotation of the motor on vacuum packaging machines with three-phase power
supply. The direction of rotation is indicated by a sticker on the motor itself (1, fig. 8). Should the motor
rotate in the opposite direction (in this case, there is a loud clang and the bell-lid does not remain
closed) exchange two of the three supply cables in the plug (except the yellow-green earthing).
c) If necessary, exchange the position of the brass bars in the motor terminal board to turn the three-
phase motor star connection (380V/3) into the delta connection (220V/3). Then act on the two
transformers by moving the jack plugs from the 380V terminal to the 220V terminal.
d) During normal processing, the vacuum chamber and bell-lid do not require cleaning operations.
Should this operation be necessary (for example – because of product leakage from the bag) use a cloth
soaked with alcohol.
THE VACUUM PACKAGING MACHINES ARE NOT SUITABLE
FOR THE PACKAGING OF FOAMING LIQUID PRODUCTS OR
CONTAINING SUGAR WITHOUT
INCREASES DURING SUCTION OPERATION THUS CAUSING
PRODUCT LEAKAGE FROM THE BAG.
