Cooling Tank
Cooling Tank is engineered for efficient temperature reduction in food processing operations. Constructed with high-grade stainless steel (304/316L), it features a jacketed design that enables circulating cooling media (chilled water, glycol, or ice water) to facilitate uniform heat exchange. Equipped with a variable-speed agitation system, it enhances heat transfer efficiency while ensuring product homogeneity. The hygienic design, with smooth welds and accessible cleaning ports, complies with strict food safety standards (FDA/3-A). Customizable options—including capacities, insulation, and automated controls—make it ideal for applications like cooling pasteurized products, thickening sauces, or chilling beverages, delivering optimal quality and operational reliability.

Product Details
Working Principle
The Cooling Tank operates via indirect heat exchange. Product is loaded into the inner vessel, while a cooling medium (chilled water, ice water, or refrigerant) circulates through the surrounding jacket. A agitation system (anchor, propeller, or frame impeller with variable-frequency drive) stirs contents to create turbulent flow, maximizing contact between the product and tank wall to boost heat transfer. A thermostat or PLC system regulates cooling medium flow and agitation speed, enabling precise temperature control to prevent thermal damage or quality issues.
Features
Stainless Steel Construction:
Food-grade 304/316L stainless steel ensures corrosion resistance and easy cleaning.
Hygienic Design:
Smooth internal surfaces, polished welds, and sloped bottoms support thorough Clean-In-Place (CIP); complies with FDA/3-A standards.
Efficient Agitation:
VFD-controlled mixing adapts to viscosities, ensuring uniform cooling with no dead zones.
Insulation Option:
PU foam or rock wool insulation with cladding reduces thermal loss, stabilizes temperature, and prevents condensation.
Automated Control:
PLC/HMI systems enable real-time temperature monitoring, data logging, and recipe management for consistent processes.
Safety Features:
Pressure sensors, overflow ports, and emergency shutdowns ensure safe operation.
Technical Highlights
Jacket Design:
Full or half jacket options with optimized surface area for heat transfer coefficients of 80–120 W/(m²·K) (with agitation).
Surface Finish:
Internal Ra ≤ 0.4 μm (mirror) or ≤ 0.8 μm (brushed); external polish or sandblast finish suits high-viscosity products.
Sealing System:
Mechanical seals (John Crane/Burgmann) with cooling/lubrication for long-life performance in vacuum/pressure operations.
Customization:
Available in 50L–5,000L capacities; optional steam heating, sight glasses, manholes, and sampling ports.
Application Fields
Food Industry: Cools pasteurized milk, yogurt, sauces (tomato, BBQ), fruit purees, soups, syrups, and beverages (juices, beer, soft drinks) post-thermal processing to inhibit bacterial growth or preserve texture.
Other Sectors: Used in pharmaceutical (API cooling), chemical (reaction temperature control), and cosmetic manufacturing for precise cooling of viscous or heat-sensitive materials.
