Frequently Asked Questions
What is a PZPK variable capacity tank used for?
The PZPK variable capacity tank is designed specifically for red wine production. It is commonly used for fermentation, storage, maturation, and simple vinification of red wines. Its design allows wineries to efficiently process grape must and manage pomace during the winemaking process.
Why is a sloped bottom important in a red wine fermentation tank?
A sloped bottom fermentation tank helps wineries remove grape skins, seeds, and pomace more easily after fermentation. The PZPK tank also includes a large square discharge door, allowing fast and efficient pomace ejection, which is especially important during red wine production.
How does the variable capacity floating lid work?
The floating lid sits directly on the surface of the wine or must and creates an airtight seal using an inflatable gasket. This prevents oxygen contamination while allowing the tank to operate at any fill level, making it ideal for wineries with varying production volumes.
What temperature control options are available for the PZPK tank?
The PZPK tank can be equipped with a dimple cooling jacket, which circulates a cooling or heating medium such as glycol. This allows winemakers to precisely control fermentation temperatures, which is essential for maintaining quality during red wine fermentation and storage.
Why do wineries choose Letina PZPK variable capacity tanks?
Letina PZPK tanks are designed for efficient red wine fermentation and cellar workflow. Key features like the floating lid variable capacity system, sloped bottom for pomace discharge, and optional temperature control jacket make them a practical solution for modern wineries seeking flexible stainless steel fermentation tanks.
