Low Pressure - Filling with low pressure inert gas tecnology
adopted in systems for bottling still or slightly carbonated products, such as
wines, spirits, etc. for which traditional vacuum or gravity bottling systems
are limited or inadequate.
It is characterised by the constant pressure of inert gas aimed at performing
important safety actions:
it isolates the product from any contact with the air, preventing both
dangerous microbiological pollution as well as oxidation caused by the increase
of oxygen during bottling;
it avoids the dispersion of volatile components, preserving dissolved aromas,
fragrances and gases and all the organoleptic qualities specific to each
The filling valves represent the most innovative aspect of the hyperbaric - low
pressure - filler, allowing precise and repetitive levels.
Through the tubes for evacuating the air from the bottle - present on each valve
- it is possible to convey the air extracted from the bottles outside the
filling tank, avoiding microbiological pollution and contact between the oxygen
and the product.
The filling valves are self-levelling.
They allow manual adjustment on every single valve for format change. The
machines can be equipped with a device to manage the simultaneous variation of
the levels on all the valves (0-80 mm) from the control panel, or with default
programming via PLC;
The ring-shaped filling tank, with a hermetic seal, has the internal
compartment completely free of the air evacuation tubes, making washing and
sterilisation operations considerably easier.
A central resting tank allows the product to settle before being placed in the
Recycling washing CIP, without the need for false bottles (Alfatek patent).
