Stainless Steel Wine Floating Lid Tank

A floating lid tank, also known as a variable capacity tank or floating top tank, is a type of wine fermentation and storage vessel used in winemaking. It is a versatile tank designed to accommodate different volumes of wine while minimizing the contact between the wine and air, which helps preserve the wine’s quality during fermentation and aging.

Floating lid tanks are especially popular in small to medium-sized wineries that produce a variety of wines in different quantities. They offer flexibility and convenience, allowing winemakers to adapt to varying production volumes and optimize the winemaking process to achieve the desired wine characteristics.

 

Product details

 

A floating lid tank, also known as a variable capacity tank or a floating top tank, is a type of storage vessel commonly used in winemaking and some other liquid fermentation processes. It is designed to allow for the expansion and contraction of the liquid inside the tank while minimizing contact with air, which can lead to oxidation and spoilage.

1.Here’s how a floating lid tank works and its main features:

1)Construction: A floating lid tank is typically made of stainless steel and has a cylindrical shape. It consists of two main parts: a fixed lower portion that holds the liquid and a floating lid that rests on the surface of the liquid.

2)Variable Capacity: One of the main advantages of a floating lid tank is its ability to adjust its capacity to accommodate different volumes of liquid. The height of the floating lid can be adjusted by using a manual or automated system. This feature allows winemakers to fill the tank partially or fully, depending on the volume of wine they want to store, and ensures minimal headspace (air) when the tank is not full.

3)Airlock System: Floating lid tanks are equipped with a special airlock system that allows gas (usually nitrogen or argon) to be introduced into the space between the liquid and the floating lid. This gas displaces the oxygen-rich air and creates a protective layer, reducing the risk of oxidation and spoilage.

4)Seal: The floating lid is designed to create a tight seal against the inner walls of the tank, preventing air from entering the tank. The seal can be achieved with a gasket or an inflatable tube around the perimeter of the lid.

5)Temperature Control: Many floating lid tanks come with an integrated cooling or heating system, allowing winemakers to control the temperature of the wine during storage.

6)Fermentation and Aging: Floating lid tanks are used for both primary fermentation and aging processes. During fermentation, carbon dioxide produced by the yeast lifts the floating lid, but the airlock system still ensures minimal contact with air. For aging, the floating lid is lowered to the wine’s surface, providing a tight seal to protect it.

7)Cleaning and Maintenance: Floating lid tanks are designed for easy cleaning and maintenance. The floating lid can be removed for thorough cleaning, and the tank’s stainless steel construction makes it durable and easy to sanitize.

Floating lid tanks are a valuable tool for winemakers who need flexibility in tank capacity and want to maintain excellent wine quality during fermentation and aging. The ability to adjust the tank’s volume and minimize air exposure helps preserve the wine’s freshness, aromas, and flavors.

2.Advantage for using the floating lid tank :

The floating lid tank is a valuable tool that addresses the challenges of oxygen exposure and variable tank capacity in liquid fermentation processes. Its features contribute to the production of high-quality wines and other beverages while providing efficiency and ease of use for winemakers and other fermentation professionals.
