Choosing an energy efficient, low-waste filling machine may lead to significant cost savings in the long term.


As previously covered in our blog, Galdi produced a research study in partnership with the University of Padua to study and reduce our filling machines’ energy and water consumption and CO2 emissions.

By embracing the concept of eco-design, our company shifted its focus towards ensuring the lowest possible impact on the environment and management costs since the earliest planning stages. Galdi's RG270 was our first filling machine manufactured according to this philosophy.

Among its several improvements, let’s focus on the solutions introduced to minimise consumption as well as product and carton waste.


ECO MODE

This smart automatic mechanism adjusts the filler’s speed and consumption according to the other systems on the line, without halting the machine. In case of end-of-line slowdowns, the machine is designed to bring down consumption levels to the bare minimum. Among its long-term results are significant reduced wear of the machine's components.


POWER STEERING CAP APPLICATOR

The bespoke linear power steering cap applicator allows our RG270 to operate at speeds higher than 6500cph, for maximum precision and continued performance. But there’s more. It also requires incredibly low amounts of compressed air to function, one of the most significant elements in the filler’s total consumption. In Europe and the US, where energy costs are higher, this results into significant savings especially when working across three shifts.


VOLUMETRIC DOSER

Regardless of the product’s viscosity and frothiness or the presence of fibres and pieces of fruit, the weight and volume of first carton are correctly calibrated at every production start or product change, thanks to a special volumetric doser. This allows the number of unfit cartons to be kept to a minimum, with the exception of the initial ones which get discarded after sanitization. Given the amount of litres/kilos of product waste at every tank recharge, it is easy to see the impact of this item on the filler’s overall balance.


TANK EMPTYING

The volumetric doser allows reducing product waste even when production ends. The new emptying procedure ensures that packages are confectioned with the highest precision even after the product runout signal, reducing the amount of product remaining in the tank and its connected piping.




OUR PATH TO IMPROVEMENT NEVER STOPS

Indeed, our prototypes area is working relentlessly to enhance the performance and lifetime of components.

While energy efficiency and reduced waste are certainly important for a filling machine, there are several elements to consider when looking at its management costs. In our efforts to keep improving our machines, we strive to take them all into account.
