Elevate your food & beverage processing with our Double-layer Spiral Coil Steam-Cooled Evaporator. Manufactured by Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with annual export values reaching US$5–10 million, this evaporator is engineered for rigorous sanitary standards. Our deep expertise in metal fabrication and precision engineering ensures that every unit delivers reliable performance in demanding environments such as dairy, juice, beer, and sauce production. The double-layer spiral coil design maximizes heat transfer efficiency while maintaining the highest hygiene levels required by the food industry.
This evaporator is specifically designed to handle steam cooling applications where rapid temperature reduction and product purity are critical. The sanitary design eliminates crevices and dead zones, making it easy to clean and resistant to bacterial growth. Whether you need to concentrate fruit juices, evaporate whey, or cool hot syrups, our steam-cooled evaporator offers a compact, energy-efficient solution that integrates seamlessly into existing production lines.
Key features include:
- Double-layer spiral coil configuration: Provides extended heat transfer surface area within a compact footprint, improving thermal efficiency by up to 30% compared to single-layer designs.
- Steam-cooled operation: Uses saturated steam or superheated steam as the cooling medium, enabling precise temperature control and rapid heat removal without product contamination.
- Sanitary design: All product-contact surfaces are made of 304L or 316L stainless steel, polished to Ra ≤ 0.8 μm. Welds are fully passivated, and the coil assembly is free of internal threads, corners, or gaps that could trap residue.
- Easy maintenance: Modular construction allows quick disassembly of the coil bundle for inspection or cleaning. The outer shell can be opened without special tools, reducing downtime.
- Customizable connections: Available with tri-clamp, flanged, or threaded fittings. Inlet/outlet positions can be adapted to your plant layout.
- High pressure and temperature ratings: Designed for working pressures up to 10 bar (145 psi) and temperatures up to 200°C (392°F), with optional higher ratings upon request.

Benefits for your food & beverage operation:
- Improved product quality: Gentle steam cooling prevents thermal shock and preserves flavor, color, and nutritional value of sensitive products like fruit juices, dairy, and liquid eggs.
- Higher throughput: Efficient heat transfer reduces processing time, allowing you to produce more batches per shift.
- Lower energy costs: The double-layer spiral coil design optimizes steam usage, reducing overall energy consumption compared to conventional shell-and-tube evaporators.
- Simplified cleaning: The sanitary design meets 3-A and EHEDG guidelines, enabling quick CIP (Clean-in-Place) cycles without disassembly.
- Space saving: Compact footprint helps you maximize floor space in crowded production areas.
- Long service life: High-quality stainless steel construction and precision welding ensure durability under continuous operation.

Frequently Asked Questions
-
What is the typical delivery time for this evaporator?
Standard models are usually shipped within 30–45 days after order confirmation. Customized units may require 45–60 days, depending on complexity. -
Can this evaporator be used with ammonia or other refrigerants?
While specifically designed for steam cooling, the double-layer spiral coil can be adapted for other cooling media such as ammonia, brine, or glycol. Please consult our engineering team for compatibility. -
Is the coil removable for cleaning or replacement?
Yes, the coil bundle is designed to be removable. The outer shell has a hinged or bolted cover that allows easy access, and the coil can be lifted out for thorough cleaning or replacement. -
What certifications does your factory hold?
Our manufacturing processes comply with international quality standards. We can provide material certificates, pressure test reports, and other documentation upon request. Specific product certifications depend on the customer's requirements and destination country regulations. -
What is the maximum capacity (evaporation rate) available?
Capacity is customizable. Typical units range from 500 kg/h to 10,000 kg/h of water evaporation. Larger capacities are available through multiple units in parallel or custom designs. -
Do you offer installation and commissioning support?
Yes, we provide remote technical support and can arrange on-site assistance for large projects. Detailed installation manuals and drawings are included with every shipment. -
How do I determine the correct size for my application?
Please provide your product flow rate, inlet/outlet temperatures, desired concentration, and available steam pressure. Our engineering team will perform a thermal design calculation and recommend the appropriate model. -
Is the unit suitable for CIP (Clean-in-Place) cleaning?
Absolutely. The sanitary design with smooth internal surfaces and no dead ends allows effective CIP cleaning. We recommend using caustic and acid solutions at temperatures up to 85°C for optimal results.
