With outstanding features such as the double-sided diaphragm, the upright stainless steel channels and the large feed opening along the entire length of the press, the MERLIN is still state of the art today.
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.
Less pressure, fewer rotations and fewer pressing cycles result in less fine trub. The amount of lees produced by pressing is up to 40 % lower than with conventional static presses and even several times lower than with non-static presses. It is not uncommon for us to observe only 2 % lees accumulation with gentle grape preparation. As a result, the net juice yield and must quality are significantly increased due to the low lees content.
The especially large filling opening is suitable for vertical filling with mash or whole cluster, which has a considerably gentler effect on the material to be pressed.
Due to the special design of the press tank and the vertical juice channels, the juice can flow directly into the filling position, without any need to rotate the press body.
The result: The optimum pre-juicing results in a considerably higher amount of filling material (up to 25%) as compared to conventional systems.
As compared to conventional systems, the short juice paths through the vertical juice channels and the double area of pressure application allow up to 90% yield at pressures of less than 0.8 bar.
This results in extremely high-quality must. Due to the pressing principle, the pressing times are also reduced by up to 30%, as compared to conventional systems.
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.
MERLIN that is supplied with the double membrane and the vertical electropolished stainless steel juice channels lets you obtain excellent press results that are of potential benefit to you.
MERLINPLUS+ offers you a particularly large filling opening that spans the entire length of the press. This greatly simplifies and accelerates the filling and emptying processes.
Be it mash or whole-cluster filling, the unique filling opening ensures optimum distribution of the material to be pressed, while dispensing with all rotations for enhancing distribution.
The juice obtained from the mash can be discharged directly from the vertical juice channels, thus ensuring optimum pre-juicing and high filling capacities. These features significantly reduce the total pressing time, thus reducing the mechanical load on the material to be pressed.
The easy and intuitive operation via a touch panel allows access to all pressing programs that have been developed and perfected over the years and that are favoured by leading oenologists and experienced users around the globe.
Thanks to the large filling opening, the pomace can be completely emptied within a short time. For easy cleaning, the vertical juice channels can be dismantled and installed manually in a few simple steps. In combination with the corner and edge-free press body, a drastic reduction in cleaning times is achieved. This, in turn, leads to a highly hygienic cleaning result.
