What are the primary benefits of a variable capacity tank?

Variable capacity tanks allow for different fill levels while minimising headspace, which helps to reduce oxidation and maintain product quality. The floating lid adjusts to the liquid level.

How is the airtight seal achieved with a floating lid?

An inflatable gasket, typically made of food-grade rubber or silicone, is positioned around the edge of the floating lid. Once inflated, it expands to create a tight seal against the tank wall.

Is this type of tank suitable for pressurised applications?

Variable capacity tanks with floating lids are generally not designed for high-pressure applications. They are typically used for atmospheric or very low-pressure processes.

What maintenance is typically required for a variable capacity tank?

Regular cleaning (CIP), inspection of the inflatable gasket for wear or damage, and checking the integrity of valves and fittings are common maintenance tasks.

Can this tank be used for both fermentation and storage?

Yes, tanks of this design are versatile and commonly used for both fermentation processes and long-term storage of various liquid food products, thanks to their ability to minimise oxygen exposure.

Typical Specifications

Typical capacity range: Variable capacity tanks of this model class commonly range from 500 litres up to several thousand litres, with this specific unit having a stated maximum of 1100 litres.
Material construction: Units of this type are typically constructed from food-grade stainless steel (e.g., AISI 304 or AISI 316) for hygiene and corrosion resistance.
Lid type: This model features a floating lid with an inflatable gasket, which is common for variable capacity tanks to allow for different fill levels while maintaining an airtight seal.
Temperature control: While not always standard, many tanks in this class can be fitted with dimple jackets or coils for heating or cooling, requiring an external chiller or heater.
Fittings and connections: Typically includes various connections for product inlet/outlet, sampling, racking, and cleaning (CIP), often using standard hygienic fittings.
Footprint: The footprint for a 1100L tank of this design would typically be a cylindrical shape, requiring adequate floor space and vertical clearance for operation and cleaning.
