Evaporators are systems that operate continuously (continuously) based on the principle of thickening (concentrating) fluids under negative pressure, at low temperatures, by evaporation in a short time. Depending on the product type, manufacturing method and capacities of the factories; It is designed in one, two, three or more stages (multiple effect). TVR technology (Thermo Vapor Recompressor) is included in the system when operating values are appropriate. Optionally, PLC control unit can be applied. Our evaporators are of falling film type.
