Sigma wine presses are designed and manufactured by internationally renowned Willmes (established in 1918), who invented the modern pneumatic press and continue to innovate and make top quality equipment with features not found on other presses.

Sigma horizontal pneumatic wine presses feature a double-sided membrane for double the area of pressure application, vertical flexible juice channels with Perfect-Flow mesh for impressive, high quality & economically efficient press results. See Features for the Willmes Pressing Principle. It can be used for whole-cluster or mash processing; vertical or axial (supplied as standard) filling; maceration in the tank; pressing with inert gas, additional cooling, reductive or oxidative grape processing.

Models are available from 2,900 up to 32,000 litre capacities.

When compared with conventional pressing systems, Sigma benefits include:

  • 50% lower pressure - the double membrane technology doubles the area of pressure application, thereby halving the pressure at the same force
  • Higher juice yield - the short juice paths through the vertical juice channels, the perforated area of the Perfect-Flow mesh and double the area of pressure application allows yields up to 95% at pressures of less than 0.8 bar and results in an extremely high quality must
  • Shorter pressing time - with the Willmes Pressing Principle (see Features), pressing times are reduced by up to 30%
  • up to 70% less lees - a lower amount of fine lees due to lower pressure, the particularly fine mesh tissue, fewer rotations and fewer pressing cycles; the gentle processing of grapes frequently results in only 2% lees, so net juice yield and must quality are significantly increased
  • 30% more filling quantity due to the special design of the press body and the vertical juice channels, the juice can flow directly into the filling position, without rotations of the press body being required; the result is optimised pre-juicing conditions and a a considerably higher amount of filling material.

  • Double Membrane and vertical Flexidrain juice channels and Perfect-Flow mesh for shorter pressing times, larger filling quantities, lower mechanical loads on the material to be pressed and significantly higher premium-quality must yield.
  • Hermetically sealable door opening
  • Central, adjustable juice drain
  • Touch panel control centre
  • For use with whole-cluster or mash processing, vertical or axial filling, maceration in the tank, pressing with inert gas, additional cooling, and reductive or oxidative grape processing.

The Willmes Pressing Principle

Double membrane technology
In contrast to a half-sided membrane, the doublesided membrane has double the area of pressure application, meaning less pressure expenditure and less compression of the material to be pressed at the same force, which acts uniformly to be pressed from all sides.

Vertical, flexible juice channels
The double-sided membrane presses the material against the vertical juice discharge areas, which act like natural drains. Irrespective of the filling height, this results in the same short juice paths, which allows the juice to drain more directly. If the membrane is relieved of pressure (vacuum released), the material to be pressed falls together.
The lateral pressure direction and the flexibility of the juice channels lead to continual self-cleaning of the mesh tissue.
These things make the rotational effort for crumbling negligible and fewer pressing cycles are required.
The mechanical load on the material to be pressed is kept to a minimum, resulting in a lower quantity of lees and a higher yield of premium-quality juice.
