SIGMA is the most modern and efficient wine press in the world.
The SIGMA press is built with a capacity of 750 to 34,000 liters.
In contrast to the MERLIN, SIGMA has hermetically sealable lids, flexible Flexidrain juice channels and a central juice drain.
This is made possible by the double membrane technology. Applied physics in simple terms:
P = F/A (P = pressure, F = force, A = area of application).
This physical law deals with the relations between pressure, force and bearing surface. If the area of application doubles, pressure is halved at the same force.
Lower amount of fine lees due to lower pressure and the particularly fine mesh tissue, fewer rotations and fewer pressing cycles.
The lees generated by pressing are up to 70% lower than in conventional static presses and even several times lower than in non-static presses.
The gentle processing of grapes results frequently only in 2% lees. As a result, the net juice yield and the must quality are significantly increased by the low content of lees.
Vertical filling with mash via the lid opening(s) is more efficient and much gentler on quality than axial filling, as there is no need for distribution rotations, while the special design of the press body and the vertical juice channels allow the juice to flow out directly in the filling position without having to turn the press body. As a result, the design-favored pre-juicing results in a significantly larger bulk quantity (up to 50 %) than with conventional systems.
Compared to conventional systems, the short juice paths, the 4 times denser perforated surface of the Perfect Flow sieve mesh and the twice as large pressure contact surface enable up to 95% yield at pressures of less than 0.8 bar. This results in an extremely high level of must quality. In addition, the pressing times are up to 30% shorter than with conventional systems due to the pressing principle.
These are programs that are perfectly adapted to all grades and types of grape harvest and lead to optimum pressing results.
Of course, you can also enter other programs, at your discretion, if you wish to pursue specific goals or try something new.
Lower pressing power and a reduction of up to 50% of compressed air; shorter pressing times, faster and simplified cleaning – all of this means better energy efficiency, environmental friendliness and economic feasibility.
In contrast to a half-sided membrane, the double-sided membrane has a substantially larger (double) area of pressure application. In terms of physics, this means less pressure expenditure and less compression of the material to be pressed at the same force, which acts uniformly from all sides on the material to be pressed.
The double-sided membrane presses the material to be pressed against the vertical juice discharge areas, which act like natural drains. Irrespective of the filling height, this always results in the same short juice paths, which allows the juice to drain more directly and quickly. 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, thus resulting in a lower quantity of lees and a higher yield of premium-quality juice.
Thanks to the patented double-membrane technology with vertical Flexidrain® juice channels in combination with the Perfect-Flow mesh, the SIGMA offers you a unique press system that yields impressive press results of the highest quality and economic efficiency.
You benefit from a unique pressing technique. The advantages of this technique include considerably shorter pressing times, larger filling quantities, lower mechanical loads on the material to be pressed and significantly higher premium-quality must yield.
Thanks to the hermetically sealable door openings and many other innovative features, you have a wide range of applications available to you. All design requirements during grape processing are catered for, in an ambitious winery.
Whether whole-cluster or mash processing, vertical or axial filling, maceration in the tank, pressing with inert gas, additional cooling, reductive or oxidative grape processing – all options are available with the SIGMA.
The easy and intuitive operation via a touch panel allows access to all pressing and cleaning programs that have been developed and perfected over the years, together with leading oenologists and experienced users worldwide.
The vertical juice channels can be dismantled and installed in no time for easy cleaning. In combination with the corner and edge-free pressing body, this results in a drastic reduction in cleaning times and leads to a highly hygienic cleaning result.
The special design of the SIGMA allows an automatically controllable juice drain at a central point. This saves space, prevents unwanted oxidation and environmental influences, simplifies the logistics of the juice control and keeps the press clean.
