Winery Variable Capacity Vessel

Winery Variable Capacity Vessel

The variable capacity vessel (VCT) is essential professional equipment for modern wineries. Equipped with an adjustable floating lid, it can adapt to different liquid volumes inside the tank. It eliminates air headspace above the liquid surface, effectively blocking oxygen contact, protecting wine aroma, preventing oxidation, discoloration and flavor loss during long-term maturation and storage.

This multi-functional vessel supports wine fermentation, aging, blending and buffer storage. It is ideal for red wine, white wine, fruit wine, craft cider and fruit vinegar production.

Main Features

1. Anti-Oxidation Floating Lid System

The floating lid rises and falls automatically following liquid level. Zero headspace design stops wine oxidation, retains original flavor and aroma for long-term ageing.

2. Food-Grade Inflatable Sealing Gasket

FDA approved silicone sealing ring, tightly fitted between floating lid and tank wall. Excellent airtight performance, no air infiltration, safe contact with beverage liquid.

3. High Hygienic Tank Construction

Full TIG seamless argon welding, internal mirror polishing Ra ≤0.8μm, no sanitary dead corners. Suitable for CIP automatic cleaning, no residue and avoid cross-contamination.

4. Optional Dimpled Cooling Jacket & Insulation Layer

Laser welded dimple jacket provides uniform temperature control. External PU insulation stabilizes storage temperature and reduces energy consumption.

5. Flexible Customization

Available capacity from 100L up to 30000L. Optional conical or flat bottom, manhole, sampling valve, racking arm, level gauge, exhaust valve and CIP ports.

6. Easy Operation & Maintenance

Stainless steel manual windlass for smooth lifting of floating lid. Simple structure, low failure rate, easy daily cleaning and maintenance.
