WILLMES – QUALITY HAS A NAME

Since 1918 the name WILLMES has stood for the highest quality in agricultural machinery and wine presses.

Our engineers invented the pneumatic grape press in 1951. With the increasing specialisation in the matter of pressing technology, further developments then followed, which set the „golden standard“ that is in place even today, throught the design of pneumatic grape presses with membrane technology.

WILLMES-presses combine the highest processing quality with German engineering skill. The result: Press systems that meet the highest requirements of quality and efficiency in grape processing.
All WILLMES-presses are manufactured in Germany.

THE WILLMES FORMULA FOR SUCCES

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 filter screen.
These things make the rotational effort 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 solids and a higher yield of premium-quality juice.
