A stirring vessel (also called an agitated tank, mixing vessel or mixing tank) is an industrial container fitted with a mechanical agitator to mix, dissolve, suspend or react fluids. Stirring vessels combine a tank body (typically cylindrical, dished or flat-bottomed), an agitator (impeller, anchor, turbine or helical ribbon) driven by a top, side or bottom-mounted motor, and often a heating/cooling jacket, baffles, ports and sensors. They’re the core unit operation in batch chemical production, food formulation, cosmetic manufacture, pharmaceutical compounding and wastewater treatment.
Well-specified stainless steel stirring vessels commonly operate for 30-50+ years. The tank body itself is extremely long-lived; agitator bearings, mechanical seals and gearboxes require periodic overhaul, typically every 3-7 years depending on duty. Jacket coils or half-pipes can corrode after 15-25 years in heating service and may require inspection or relining.
Stirring vessels provide the controlled, repeatable batch processing environment essential for most formulated products.
Vessels are one of the best-value used-plant purchases because the main tank body rarely wears out.
The most common configuration. The agitator shaft enters through the top of the tank, driven by a gearbox and motor mounted above. Suits most mixing and reaction duties, marine propellers for blending, Rushton turbines for gas dispersion, anchors for viscous blending and helical ribbons for very high viscosity.
Side-entry mixers are used in large storage and blending tanks where top-entry drives would be impractical. Bottom-entry agitators (also called bottom-magnetic mixers when sealless) provide strong mixing in smaller sanitary vessels without the overhead shaft, ideal for pharma and biotech.
Feature a heating/cooling jacket on the outer wall, full jacket (annular space), limpet (half-pipe) coils or dimple jackets. Jacketed vessels run batch chemistry, crystallisation, pasteurisation and product melting. Check jacket design pressure and temperature rating against your utility.
Pressure-rated vessels support reactions under pressure, autoclaving and vacuum distillation. PED (Pressure Equipment Directive) / UKCA / ASME certification is essential for any vessel operating above 0.5 bar gauge, verify documentation before purchase.
Electropolished 316L stainless steel, sanitary tri-clamp connections, CIP spray balls, fully-drainable dished ends and certified welding support food, dairy, beverage, cosmetic and pharmaceutical duties. Key certifications: 3A, EHEDG, FDA, GMP.
Purpose-built pressure reactors with agitation, jacket and process connections for catalytic reactions, hydrogenation and polymerisation. Also see our reactors category for specialist chemistry vessels.
