Jacketed Evaporators

Jacketed insulated evaporators are specialized vessels designed to remove volatile components (typically water or solvents) from solutions through controlled heating and evaporation. The jacketed design provides efficient heat input for evaporation, while insulation minimizes heat loss and maintains thermal efficiency throughout the concentration process.

Why are Jacketed Evaporators Needed?

Jacketed insulated evaporators are essential for concentration, solvent recovery, and purification processes across numerous industries. Efficient evaporation requires consistent heat input to maintain evaporation rates while controlling product temperature to prevent thermal degradation. The insulated jacket system maximizes heat utilization while protecting heat-sensitive products.

Jacketed Evaporators Applications

Common applications include:

• Food product concentration
• Pharmaceutical solution concentration
• Solvent recovery operations
• Waste stream concentration
• Extract concentration
• Chemical solution evaporation

Jacketed Evaporators Frequently Asked Questions (FAQs)

What types of evaporator configurations are available?

We fabricate various evaporator configurations including batch pan evaporators, natural circulation evaporators, forced circulation evaporators, falling film evaporators, and wiped film evaporators. Configuration selection depends on product characteristics, throughput requirements, and heat sensitivity. Our engineering team recommends optimal designs for your application.

How does vacuum operation benefit heat-sensitive products?

Vacuum operation reduces boiling point, enabling evaporation at lower temperatures that protect heat-sensitive products from thermal degradation. A vacuum evaporator operating at 25 inches Hg can evaporate water at approximately 130°F instead of 212°F at atmospheric pressure. This enables concentration of temperature-sensitive pharmaceuticals, foods, and biologicals.

What energy efficiency features are available?

Energy efficiency features include multiple-effect configurations that reuse vapor energy, mechanical vapor recompression (MVR) that upgrades vapor for reuse as heating steam, and thermocompression systems. Proper insulation is essential for all configurations, preventing heat loss that reduces evaporator efficiency and increases operating costs.
