  Types of Evaporator

  Type	Falling Film Evaporator (FFE)	Forced Circulation Evaporator (FCE)	Natural Circulation Evaporator (NCE)
  Applicable Fluids	Ideal for low-viscosity and non-crystalline products Suitable for heat-sensitive materials	Suitable for high-viscosity and crystalline slurry products Recommended for products prone to scaling	Suitable for small-volume products Applicable to products stable at high temperatures
  Advantages & Disadvantages	Operates with a small temperature difference Small operating volume allows for short residence time and minimal CIP burden Maximized heat transfer area, ideal for large scale operations Enables energy-efficient concentration using waste heat recovery, multi-effect evaporation, TVR, and MVR Relatively small installation footprint Low power consumption	High resistance to scaling, allowing for long-term continuous operation Energy-efficient for crystallization using multi-effect evaporation, TVR, and MVR Large operating volume reduces hunting during continuous operation, enabling stable performance, but results in a relatively high CIP burden. Relatively high power consumption.	Heating via vertical tubes allows natural circulation without a circulation pump due to density difference Compact design suitable for both batch and continuous processes Natural circulation has limitations based on density difference, restricting system capacity Not using forced circulation leads to relatively low resistance to scaling
  Typical Applications	Wide use in food, pharma, chemical industries	High-viscosity concentration Organic/inorganic crystallization	Multi-product, small-batch production

  Types of Crystallizers

  Type	Forced Circulation Vortex Crystallizer	Forced Circulation D.T.B. Crystallizer	Oslo Crystallizer
  Applicable Fluids	High-viscosity / crystalline slurry	Products requiring high-purity crystal yield	Products requiring large-scale operation and high-purity crystal yield
  Advantages & Disadvantages	Simple internal structure of the crystallizer Excellent operational stability under continuous operation Wide crystal particle size distribution	Requires a dedicated crystal growth zone Relatively long residence time due to recirculation of ungrown crystals Delivers a relatively uniform crystal particle distribution	Maximized residence time through a dedicated crystal growth chamber Enhanced crystal growth via uniform contact of ungrown particles Consistent separation efficiency with uniform crystal particle distribution
  Typical Applications	Widely applied in processes focused on solid-liquid separation	Suitable for products requiring high crystal purity	Designed for applications where crystal purity is critical Relatively well-suited for large-scale production
