Filling turret
by simple gravity

gravity filling

STONE Industrie introduced the first Automatic Gravity Filler in the year 2000. Your future high-speed monobloc will incorporate this technology, with its proven advantages!

What are the advantages of gravity filling

Gravity filling ensures that your liquid to be bottled is filled with no suction, to stop any air being introduced. But that's not all: this technique also allows for levelling to be carried out directly..

The liquid can be fed either by gravity (when the vat room is located  on the upper floor or above the filler) or with the help of a wine pump. Filling and levelling are carried out by simple gravity with no suction. Vacuum levelling is not used on STONE Industrie fillers so as to avoid air mixing and to guarantee a very low level of dissolved oxygen or alcohol loss in the product.

Expert technology for unbeatable product quality

The filling phase is notoriously challenging, as are the various packaging stages.

During the liquid filling process, the risks of aroma and CO² loss, the reduction of SO² and alcohol content or the oxygenation of the product can vary according to the filling technology used, sometimes in significant proportions.

The STONE Industrie teams have successfully developed and perfectly understand the filling technology required by the Automatic Gravity Filler.

The direct levelling of the liquid without suction ensures:

How the gravity filler works

The STONE Industrie gravity filling turret is automatically adjusted to the bottle size via touch screen selection:

  • Electric height adjustment
  • Electric adjustment of the screws and rails


Filling at constant levels is carried out by gravity filling of still liquids, with direct levelling without suction, with possible millimetre adjustment of the headspace during the filling operation.

Neck centering is carried out using centering cones.

Automatic sanitizing (thermal or chemical):

  • Closed circuit system for dynamic countercurrent sanitizing
  • No risk of contamination by handling the filling devices before, during and after the cleaning cycle
  • Option of sanitizing as a background task

Addition of an inert gas stage before filling

To take things even further and satisfy our most demanding customers in terms of dissolved oxygen, we can add a neutral gas injection stage to the empty bottle before filling.

Two different technologies can be implemented: inert gas or inert liquid dosing.

Inert gas dosing involves the addition of a turret to inject a neutral gas (nitrogen) into the empty bottle to expel air (and therefore oxygen).

The Liquid nitrogen dosing system requires a liquid nitrogen injection device. A drop of nitrogen injected into an empty wet bottle turns into a gas cloud that purges the bottle. This solution can easily be installed on an existing line.

These empty bottle purging devices prior to bottling guarantee excellent oenological results.
