Flash Coolers
The Anhydro® Flash Cooler provides rapid, gentle cooling of concentrated liquids immediately after evaporation. It helps dairy and food processors preserve flavor, color, texture and nutritional value while enabling precise crystallization control in products like sweetened condensed milk, whey permeate powder and lactose.
Product Features
In dairy and food concentrate production, protecting product quality doesn’t stop at evaporation—it depends on fast, precise cooling. SPX FLOW’s Anhydro Flash Cooler rapidly reduces product temperature under vacuum to control texture and crystal formation. It’s ideal for applications where crystal size and mouthfeel must be carefully controlled.
Today’s processors face critical cooling challenges:
- Preserving mouthfeel in concentrated products such as sweetened condensed milk
- Controlling crystallization for optimal performance in downstream processing
The Anhydro Flash Cooler addresses these challenges with:
- Flash cooling under vacuum to minimize heat exposure
- Controlled cooling zones for consistent crystal formation
- Vapor recovery to reduce upstream energy load when integrated with an evaporator
- Hygienic, CIP-compatible construction
- Automated control for precision and reliability
Why Choose Anhydro Flash Coolers?
- Designed for rapid cooling of heat-sensitive products
- Enables precise crystallization control for superior quality
- Suitable for standalone or integrated system configurations
- Backed by decades of SPX FLOW thermal processing expertise
- Our experts can perform all necessary calculations to ensure seamless integration into your process
- Supported by global service, engineering and technical support teams
Distinctive Advantages

- Proven know-how in specific applications and product compositions to ensure optimal results
Product Applications
- Lactose
- Milk & Cream
- Sweetened Condensed Milk
- Whey Permeate Powder
Theory of Operation
The Anhydro Flash Cooler works by exposing concentrated liquid to vacuum conditions, causing a portion of the product to evaporate instantly. This flash evaporation cools the product rapidly.
It is especially effective in processes requiring crystallization control. By managing the cooling profile and temperature zones, it ensures proper crystal size and consistency in products like sweetened condensed milk, whey permeate and lactose. Recovered vapor can be condensed and reused, further improving energy efficiency.
- Cooling Capacity: Customizable based on product type and production volume.
- Operating Temperature Range: Tailored to various concentrate profiles
- Materials: Constructed with high-quality stainless steel for hygiene and corrosion resistance.
- Energy Efficiency: Low energy consumption due to vapor cooling technology.
Custom configurations available to match existing production line layouts and facility constraints.
- Standalone or fully integrated configurations
- Crystallization profiling for specific product needs
- Integration into existing process automation system
The Anhydro Flash Cooler rapidly cools concentrated products through flash evaporation under vacuum. This process protects sensitive components and enables consistent crystallization in dairy applications such as sweetened condensed milk, whey permeate, and lactose. SPX FLOW Flash Coolers are ideal for temperature-sensitive liquids—including dairy products, sweetened condensed milk, whey derivatives, juices, and nutraceuticals—where rapid cooling and product integrity are critical. They are often integrated into heat treatment systems to improve overall process performance.
By using vapor flash cooling under vacuum, the system eliminates the need for traditional cooling methods. The evaporated vapor is condensed and recovered for reuse, reducing the thermal load on downstream equipment and significantly lowering overall energy consumption and operating costs.
The Flash Cooler is primarily used for crystallization control in dairy applications but is also effective for cooling a wide range of temperature-sensitive liquid products.
The system provides precise control over cooling zone temperatures, helping form uniform, correctly sized crystals. This supports the desired texture, solubility, and non-caking properties of the final product.
Absolutely. The Flash Cooler is fully CIP-compatible and built from hygienic, corrosion-resistant materials to support sanitary operation and reduce cleaning downtime.
Advanced automation delivers real-time monitoring, accurate temperature control, and seamless integration with your central process control system.
