Crystallization

Sulzer is the leading supplier of technology for solvent-free melt crystallization. We are the only company offering equipment for suspension, static, and falling film crystallization as well as for freeze concentration, thereby offering the best solution to meet your requirements.

Static crystallizer — Static crystallization is a process using vertical plates, heated or cooled by an internal circulation of heat transfer medium (HTM). The plates are suspended in the molten feed. Slow cooling of the HTM below the freezing point of the stagnant melt causes a layer of crystals to grow on the plates.

Falling film crystallizer elements — Thanks to our satisfied customers, falling film crystallization is the leading melt crystallization technology for high-purity applications. We work with you to design a new plant that optimally meets your requirements.

Suspension crystallization plant — Besides static and falling film, suspension crystallization is an industrially used melt crystallization technology. The specific advantages of this technology include a compact layout, high purity in one step, low energy consumption, and low installation costs.

freeze concentration — The quality of freeze concentrated products cannot be achieved by any other concentration technology. Industrial applications include concentration of juices and coffee extracts.
