SPHERA - the ball press, without corners and edges, with the possibility of pressing grapes statically, without rotation, i.e. without additional mechanical stress.
A round press without corners and edges, developed for pressing red wine mash and whole grapes without rotation. Thanks to the patented 360-degree pressing principle and the air distribution system, the membrane inflates evenly, forming a uniform pomace cake around the flexible juice channel. This enables optimum juicing at minimum pressure.
Regardless of whether you fill the press with 100% or only 10% grapes, an even cake forms around the FLEXIDRAIN juice channel, allowing the juice to be efficiently filtered through the cake. This design mimics the traditional basket press, with all the benefits of a modern membrane press.
The 360-degree pressing principle provides a larger surface area for juice extraction, resulting in faster juicing, with much less pressure than a traditional basket press. During pressing, the grapes remain in place and are pressed evenly from all sides without damaging the skin to minimize the lees. The result is that the Sphera produces 70% less lees in the juice compared to conventional presses.
In addition to the qualitative advantages that SPHERA brings with it, we have placed great emphasis on the functional and simple operation.
Filling: Simple and efficient, thanks to the frameless 600mm lid opening, can be easily filled directly with a conveyor belt, funnel or small reading boxes.
Emptying: Quick, as the pomace is emptied into the juice and pomace tray simply by rotating the container. After a few rotations, the container is empty and the tray can be removed by forklift.
Cleaning: SPHERA has a cleaning program in which water is poured into the container. As soon as the lid is closed, the cleaning program starts and the inside of the press is cleaned through rotations. The lack of corners guarantees quick cleaning.
The green arrows show the effect of mash filtration when the must flows through the 360° pressing in the center of the inner juice channel of the press into the juice bowl.
1. can I press whole grapes with the Sphera?
Yes, the Sphera is ideal for small batches of whole grapes. Lower pressure is required for juice extraction, which leads to higher quality results.
2. is it possible to carry out maceration times?
Yes, the closed press tank has a manually operated juice valve which can be closed for the mashing time. A special pressing program is then recommended to extract the juice without high pressure. This extracts up to 80 % juice, an option that traditional basket presses cannot offer.
3. what is the minimum and maximum pressing capacity of the SPHERA?
The press can process fill levels from 10% to 100%.
4. why is the press container spherical?
The spherical container design allows the membranes to be inflated evenly by 360 degrees, which makes it possible to press from all directions at lower pressure.
5. do the red wine programs require rotation?
No, the Sphera works without rotation when pressing red wines, creating a pomace cake around the juice channel through which the juice is efficiently filtered. The young wines obtained have very precise and varietal aromas.
6. are there rotations when processing white grapes?
Yes, but due to the smooth inside of the press, the rotations do not cause any damage to the grapes and therefore no additional lees. The number of rotations is many times lower than with conventional pressing programs.
7 What is the biggest advantage of the SPHERA?
The Sphera combines the advantages of a traditional basket press with the flexibility of being able to press white grapes and mash. The flexible juice channel contributes significantly to the must quality, and the press is designed so that only the minimum of manual effort is required.
After filling via the door, without manual distribution of the grapes, the new 360° membrane presses the grapes evenly from the outside inwards to the central, flexible juice channel.
The result is the purest musts, which are automatically pressed to the desired degree with SPHERA.
After pressing, only a round container with a comprehensive membrane needs to be cleaned.
From the available model sizes with a capacity of 1,000 and 2,000 liters, the right requirement can be met for any high-quality white or red wine processing.
