The most important piece of the entire bottling line is without a doubt the bottle filling machine. This component is the only machine that has direct contact with the finished product and must therefore ensure maximum reliability in terms of hygiene and quality of the end product. This means preserving the product’s characteristics during the filling phase and being easy to clean or, when in contact with products that are particularly sensitive to contamination, easily sterilised.
During the filling phase, liquid products to be packaged can be foamy, dense, creamy, fluid, powder or granules. They are delivered into special package types such as bottles, vials, pots, jars, cans, tanks, buckets, tins, bags, sacks or bag-in-boxes.
There are different filling processes (negative pressure, gravity, isobaric) which utilise different types of fillers, including volumetric fillers with batching syringes, gravity fillers with electronic or mechanical weighing units, and negative pressure fillers at constant levels (suitable only for very rigid recipients). The machines are set and calibrated to help ensure flawless operation and exceptional precision.
