The structure design of Pipeline Pressurized Steam Compressor is same as gearbox drive steam compressor, driven by motor with speed up gearbox. Pipeline Pressurized Steam Compressor is mainly used for RE-compression of steam at high pressure and high temperature. To fit for the high pressure and high temperature steam, the material selection of the main parts is very different from the conventional Gearbox drive steam compressor.

MVR falling film evaporator is improved model by MVR technology. By adding steam compressor and necessary match parts, the new model falling film evaporator can significantly increase the work efficiency and reduce operation cost. MVR falling film evaporator mainly composed of preheater, heat exchanger, separator, vacuum system, MVR steam compressor, cooling system, cleaning system and control system.

FC crystallizer composed of a crystal chamber, a circulation pipe, a circulating pump and a heat exchanger. The crystallization chamber with a conical bottom slurry discharged from the cone bottom, the circular tube axial flow type circulating pump through the heat exchanger, is heated again into the crystallization chamber, so the cycle, belonging to the slurry circulation type, slurry outlet located near the salt crystallization chamber legs.

Multiple effect evaporator is the combination of several sets single effect evaporator. The characteristic is to heat the next effect evaporator by used steam produced from the front effect, so as to reduce energy consumption. Usually there is double effect evaporator, three effect evaporator or even more effect evaporation system. More effects with more control points; the driving force of temperature difference at different effect is smaller. The system should be selected according to the job condition. The multiple effect evaporator can be divided into a common multiple effect evaporation system and a forced circulation multiple effect evaporator. Forced circulation multiple effect evaporator (FCMEE). FCMEE system is designed with several sets external circulation pump based on several sets evaporator; Increasing the flow velocity of the material in the evaporating tube, improving the heat transfer effect and increasing the intensity of evaporation.

For high viscosity liquid, it is difficult to form film by raising film or falling film. Mechanical method should be adopted to make the liquid to form film and reach better heat transfer effect. The gap between the scraper & wall of evaporator is about 0.7~1.5mm. The scraper rotates continuously with mechanical transmission, to keep the film status. Scraper film evaporator is specialized for high viscous raw material liquid. When the fluids viscosity exceed 50~100mPa.S, heat transfer coefficient of falling film or rising film will decrease sharply; When the fluids viscosity exceed 1000~10000mPa.S, falling film or rising film cannot be adopted fully. Scraper film evaporator can give better performance. Scraper evaporator is widely used in petroleum, chemical, pharmaceutical and other industries, especially suitable for high viscosity, easy fouling and heat sensitive materials.

Condense the 9%~15% concentration of syrup to saturated state, Concentration temperature requirement is not more than 80℃. Power consumption of per ton evaporation water：50KWh. Steam consumption under normal operation：280kg/h.
