- Typical capacity
- Holding tanks for this class of equipment commonly range from 50 litres up to several thousand litres, depending on specific process requirements.
- Material of construction
- Units of this type are typically constructed from food-grade stainless steel (e.g., 304 or 316) for hygiene and corrosion resistance.
- Jacket type
- Commonly features a dimpled, half-pipe, or full jacket for heating or cooling via steam, hot water, chilled water, or glycol.
- Discharge
- Often includes a central bottom discharge, typically with a hygienic valve, to facilitate complete product evacuation.
- Agitation
- Many holding tanks are equipped with agitators (e.g., propeller, anchor, or gate type) to maintain product homogeneity or prevent settling.
- Insulation
- Jacketed tanks commonly feature external insulation and cladding to improve thermal efficiency and reduce energy consumption.
- Power supply
- Heating elements, if present, typically require a 3-phase electrical supply (e.g., 400V, 50Hz in the UK). Agitators also require an electrical supply, commonly 3-phase.
