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.). That is why the pneumatic press is an indispensable device in a winery today. Open Pressing System Half of the press drum is perforated, while the other half is covered by an impermeable membrane. A built-in compressor is used to establish the desired pressure within the drum. This inflates the membrane, which consequently press the grape mass and drains the must. Must then flows through the perforated half of the drum into a collection pan. Soft grape and grape pomace membrane pressing with compressed air prevents any mechanical damage to the grapes, thus ensuring a production of high-quality must and wine. DESCRIPTION: Pneumatic press type PSP - open pressing system, open drum with perforated surface Nominal volume [hl]: 29 Automatics: Automatics type ATK Supply voltage: 230V 60Hz 3PH Max. operating press.
