Letina PZP1100 Variable capacity tank

• Wine and cider production for fermentation, maturation, and storage.
• Brewing industry for beer fermentation and bright tank applications.
• Dairy processing for milk storage, mixing, and culturing.
• Fruit juice and beverage production for mixing, holding, and clarification.
• Food ingredient storage and blending, particularly for liquid or semi-liquid products.

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.

• 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?

• Is this type of tank suitable for pressurised applications?

• What maintenance is typically required for a variable capacity tank?

• Can this tank be used for both fermentation and storage?

Tanks and silos for food handling and storage are valued for their durability and reliability when purchased used. Buyers typically prioritize stainless steel construction for hygiene compliance and corrosion resistance. Key considerations include checking internal condition, seal integrity, and compliance with food safety standards. Industry sentiment reflects that quality used tanks offer significant cost savings whilst maintaining performance. Common strengths include longevity, straightforward maintenance, and compatibility with existing production lines. Proper inspection before purchase remains essential for operational safety.
