SPHERA wine press from WiLLMES

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.
