Stainless Steel Floating Roof Tank

Home » Stainless Steel Wine Tanks » Stainless Steel Floating Roof Tank

Introduction

In winemaking, the thoroughness of fermentation and the stability of storage directly determine the quality of the final product. Our stainless steel floating-roof wine tanks integrate fermentation and storage functions into a single unit. Featuring core components imported from France, they support seamless switching between open fermentation and sealed wine storage modes.

The removable floating lid design accommodates both the intensive maceration required for red wines and the fermentation and anaerobic storage of white wines, rosés, and fruit wines. This multi-purpose functionality significantly enhances equipment utilization.

Structural Composition

Tank Body: 304/316L stainless steel material + mirror-polished inner wall, integrally welded construction with no weld seams or dead corners, ensuring no residue buildup.
Multi-functional Jacket Temperature Control System: Offers both Miler plate jackets and coil jackets covering critical vessel zones; polyurethane insulation layers can be customized for the jacket exterior.
Floating Lid System: Features French-imported core components with exceptional sealing performance, automatically rising and lowering with liquid level; fully removable lid enables rapid switching between open/closed modes to accommodate mechanical cap pressing and oxygen-free storage requirements.

Advantages of Stainless Steel Floating Roof Wine Tanks

During fermentation, the removable tank lid transforms it into an open-top vessel, enabling mechanical cap pressing to enhance pigment and tannin extraction.
After fermentation concludes, the floating lid automatically seals against the liquid surface, creating an airtight environment that effectively blocks oxygen exposure—directly transitioning the tank into a storage vessel.
Equipped with an intelligent temperature control system, it accommodates multiple processes including cold maceration, alcoholic fermentation, and malolactic fermentation, making it an ideal choice for enhancing winemaking efficiency and quality.
