PASTA PACKAGING AND PACKING
Weighing and filling systems
Main features:
-Precision to obtain packages that contain not more and not less than the stated weight
-Speed besides precision, it is the second important factor to be considered
Weighing and filling systems
Filling systems used are:• Volumetric filling system;• Net weight filling system.
product density must be uniform
by mean of electr. weighing machines
In order to ensure higher precision in weight, the feeding is divided into rough and refining;this means, for instance, that 90% of the weight is quickly fed and then slowly completed.
operator starts the filling
30-150 packs per minute
up to 500 p.p.m.
Filling systems can be: - Manual or semi-automatic; - Alternate automatic; - Continuous automatic.
Cartoning and Palletizing
The basic function of a cartoning unit is to put products inside a cardboard box.The variety of these machines may be vast, but all the different kinds are referable to three basic groups: 1.With side loading; 2.With top loading; 3.With wrapping up or wraparound.
Palletizing units are available in two different versions: with top loading or with ground level loading.
A palletizing unit with loading at ground level excludes the necessity of hoisting the cartons to a upper level (area where they are formed and filled).
example of possible combinations for cartoning pasta packets
A palletizing machine with loading from the top offers the advantage of leaving the surface underneath clear, since the boxes are conveyed to the palletizing unit just below the ceiling. Using this kind of solution, the unit can, for instance, be installed at a level beneath the packaging area.
