Grape pressing is one of the most important stages of grape processing. It is a delicate process that requires extensive knowledge, experience, and feeling. In order to achieve constant wine quality, the pressing should always be adapted to grape characteristics, most importantly grape variety, ripeness degree, and the stems to grape berries ratio. Before pressing, the winemaker has to determine the kind of wine he wants to produce in terms of style (fruity, young, wine for aging, etc.) and type (sparkling wine, rosé, etc.).

Pneumatic Membrane/Bladder Press
The pneumatic membrane press (often referred to as a bladder press) is another commonly used batch press today. Introduced in the 1950's, its basic design principle is that a rubber bladder is placed inside an enclosed horizontal drum with drainage ducts. The fruit is loaded into the drum, and as it rotates on its axis, air pressure is applied to expand the bladder.

Ideally, this creates an evenly dispersed layer of grapes around the drum, which when the bladder is expanded, presses the grapes against the drainage ducts. The juice is then extracted and collected, while also separating from the solids and pomace that remain inside the drum.

The enclosed "tank" drum of tWhen compared with conventional pressing systems, the Merlin PLUS+ 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 and double the area of pressure application allows yields up to 90% 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 40% less lees - less fine lees due to lower pressure, 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
25% more filling quantity - due to the special design of the press tank 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 materialhis press design has the advantage of some added protection from unwanted oxidation. Pneumatic presses typically have a higher fill capacity than basket presses, thus making them more ideal for larger batches. This press design also allows for intermittent press rotation while filling, resulting in very efficient drainage of free-run juice before pressing even begins. In addition to higher fill capacity, the pneumatic presses tend to output higher yields than the basket press. However, the higher yields may also indicate harder pressing, more solids, and ultimately harsher press fractions. If quantity and efficiency are desired over quality, the pneumatic bladder presses are the way to go.

The Pneumatic Presses are entirely built in AISI 304 stainless steel. Any high quality components that we use (e.g. Becker compressors, Bonfiglioli reduction units etc.) are standard, and are pivoting, braking wheels.

Through a soft and gentle pressing of the membrane, our pneumatic presses play an important role in the production of top quality wines. They can press grapes in bunches, destemmed and fermented grapes and raisins at a very high hourly output.

Their loading can take place through one or several doors or through a axial loading. The press tanks are entirely closed, thus limiting the oxidation of the product and guaranteeing a very high quality of the must. The flow of the must takes place through inner drains and through the perforated loading door.

The new control board of the press is equipped with a PLC which is pre-programmed with 6 work cycles and 3 customizable cycles ; their run duration can be customized and all working processes can also be manually controlled.

There is also the possibility to mount watertight doors for carbonic maceration.
