Thin-film Evaporators Have Excellent Properties And Are Loved By Many Industries

Wuxi Lima Chemical Machinery Co.,Ltd | Updated: Jan 24, 2018

Film evaporator is a kind of evaporator, characterized by material flow along the wall of the heating film was heated and film flow in accordance with the film and the different causes, can be divided into rising film evaporator, falling film evaporator, wiping film evaporator three types. Evaporation, the advantage of high heat transfer efficiency, evaporation speed, and material retention time is short, so it is particularly suitable for heat-sensitive material evaporation.

Thin-film evaporators have many advantages when they are used. Such devices can be used industrially. They belong to the evaporator. The whole device has high heat transfer efficiency and high evaporation speed, and the material of the thin-film evaporator has a short residence time. Therefore, favorite by many industries.

The decrease of the boiling point of the material of the thin-film evaporator increases the temperature difference with the heat medium, and the function of the wiper reduces the thickness of the liquid film in a turbulent state to some extent, effectively reducing the thermal resistance, meanwhile, In the process, the material is restrained on the heating surface nodules and scaling, accompanied by good heat exchange.

The operating temperature of the thin-film evaporator is low, which allows the evaporation to be carried out at a higher degree of vacuum. With the increase of the degree of vacuum, the boiling point of the corresponding material rapidly decreases. Therefore, the operation can be performed at a lower temperature, reduced product thermal decomposition.

Due to the unique properties of the scraper film evaporator, it is suitable for handling heat-sensitive and vapor-deposited, highly viscous and rapidly increasing viscosities as the concentration increases. The evaporation process also evaporates smoothly. It can also be successfully applied to the evaporation and distillation of solid particles, crystallization, polymerization, scaling and other materials. Thin-film evaporator has excellent performance, and it has large heat transfer coefficient, high evaporation intensity, short over-current time and flexible operation. The thin film evaporator is especially suitable for evaporation and concentration of heat-sensitive and high viscosity materials, degassing and desolventizing, and distillation and purification.
