● olvent properties: composition and corrosiveness, etc., to evaluate material compatibility with equipment and seals.● Material properties: flowability before/after evaporation, viscosity, crystal formation, or particle precipitation, to assess heat transfer and prevent clogging risks.● Process requirements: feed capacity, initial solvent content and evaporation target, etc., to determine the optimal equipment size.● Plant conditions: layout, electrical requirements, heat source, cooling, vacuum system, and explosion-proof requirements. We provide complete evaporation solutions including various supporting equipment.

The selection of condenser type and sealing material depends mainly on solvent properties and chemical compatibility.Dual Plate Condenser with EPDM Gaskets● Uses multiple gaskets between plates for sealing.● Narrow flow channels require relatively clean process fluids.● The gasket material is directly exposed to the process medium.● EPDM provides excellent resistance to water, steam, acids, and alkalis, but has limited resistance to some organic solvents, including certain aromatic hydrocarbons, ketones, esters, and ethers.Shell-and-Tube Condenser with Optional PTFE Sealing● Heat transfer and pressure resistance are mainly provided by the metal tube bundle.● Fewer sealing points compared with gasketed plate condensers.● The process medium mainly contacts the metal tube surface and limited sealing areas.● PTFE provides excellent chemical resistance, high temperature resistance, and better compatibility with corrosive organic solvents.

The secondary vapor from the evaporator may contain small amounts of entrained concentrated liquid droplets. The gas-liquid separator (cyclone separator) removes these droplets through gravity and centrifugal separation. Its main functions include:● Improving recovered solvent purity.● Preventing liquid carryover into the condenser system.● Reducing contamination and blockage risks in downstream equipment.

We provide turnkey solutions with matched heating and cooling componentsHeating options include:● Electrical heating circulator: suitable for laboratory, pilot-scale, and small production systems.● Steam generator + heat exchange module: suitable for larger industrial systems using steam as the heating source, reducing electrical load and improving energy efficiency.Cooling options include:● Standard chiller unit: suitable for general cooling requirements.● Chiller + cooling tower system: suitable for larger systems requiring higher cooling capacity and improved energy efficiency.

Falling film evaporator:● Uses thin-film heat transfer technology, where material forms a thin film on the inner wall of heating tubes and evaporates during downward flow.● Provides high heat transfer efficiency, high automation level, and lower operating costs for large-scale applications.Rotary evaporator:● Uses flask rotation to create a thin liquid film under vacuum conditions.● Limited by flask volume and heat transfer area, making it unsuitable for large-scale continuous production.For industrial production and continuous solvent recovery with large processing capacity , falling film evaporators are generally preferred. For small-batch processing, rotary evaporators are commonly used. We also provide the FFE-50L laboratory-scale falling film evaporator for laboratory process development.
