Double membrane technology
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 on the material to be pressed from all sides.
Vertical, flexible juice channels
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.
Flexidrain® – flexible vertical juice drains
Hermetically sealable doors. The door seal can easily be removed for cleaning.
Door ventilation valve (optional). Especially for the reductive expansion, the automatically controllable valve allows direct ventilation or venting in the membrane control, without the need to press air through the mash.
Axial filling valve (optional)
Central juice outlet with integrated adjustable valve
Juice pipe. Through the juice pipe, the juice from the juice channels proceeds to the central juice outlet at the lowest point outside the press tank.
Inert gas coupling valve (optional)
Must pump control (optional)
Easy mounting/dismounting of the Flexidrain®
Pneumatic control with reversible blower for an efficient and energy-saving pre-pressure and evacuation control (optional: integrated compressor)
Particularly durable special membrane
Control console with integrated touchpanel
Unique pressing technology
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.
Maximum flexibility for all requirements
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.
Intelligent control programs and maximum comfort
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.
