6.2.1 PACKING LIQUID PRODUCTS
WARNING! With lowering of the pressure inside the vacuum chamber, the liquid boiling point is lowered. Water at 23.4 absolute
mbar (corresponding to a vacuum of 97.66%) boils at 20°. Steam formation is evident from the bubbles forming inside the bag. In
this case, press the STOP button and reset the VAC parameter to such a level as to prevent bubble formation.
The operation is carried out with a help of an inclined work top for liquids (A) available as optional.
1) Lower the lid holder: the plexiglas cover of the chamber opens.
2) Remove all the insertion plates and insert the inclined work top (A) in the chamber with the upper part facing the sealing bar and sliding retainer(B)
adjusted along the bag length.
3) Insert the bag containing the liquid to be packed inside the chamber, making sure that it is only half-filled (1/2) (Fig. 1).
Place it centered on the sealing bar, so that the open end projects by about 20mm beyond the bar.
4) Repeat the operations described in the paragraphs “OPERATION AND PROGRAMMING” adjusting the vacuum time to such a value as to avoid
boiling.
WARNINGS!
• THE PRODUCT TO BE PACKED MUST BE DRY AND COLD; CHOOSE A BAG HAVING A SHAPE AND THICKNESS SUITABLE
FOR THE SIZE, HARDNESS AND ANGULARITY OF THE PRODUCT.
• THE MACHINE IS CALIBRATED FOR A STANDARD SEALING TIME; IF A NUMBER OF SEALING OPERATIONS ARE PERFORMED
CONTINUOUSLY, THE SEALING BARS WILL GET HEATED. IT IS THEREFORE ADVISABLE TO REDUCE THE TIME.
• TAKE GREAT CARE TO PREVENT SUCTION OF LIQUIDS BY THE MACHINE; USE THE MACHINE FOR PACKAGING LIQUID
PRODUCTS OR PRODUCTS WITH HIGH MOISTURE CONTENT ONLY AFTER ACQUIRING THE NECESSARY EXPERIENCE BY
FOLLOWING THE INSTRUCTIONS GIVEN IN THIS MANUAL.
