Customizable SUS304 SUS316L Single Effect Falling Film Evaporator

Product Description:

The single effect falling film evaporator is an efficient liquid concentration device based on the single-effect evaporation principle. Its core feature is that the feed liquid completes heat transfer and evaporation in the form of a thin film.

The equipment primarily consists of a heater, a separator, a condenser, etc. During operation, the feed liquid is evenly distributed to the inner wall of the heating tube via a distributor, forming a uniform falling film driven by gravity and secondary steam. Steam is introduced into the outside of the heating tube, and heat is transferred through the tube wall to rapidly boil and vaporize the feed liquid. The generated secondary steam and concentrated liquid enter the separator for separation. The secondary steam is condensed and discharged, while the concentrated liquid is collected after reaching the target concentration.

Its advantages are significant: the large heat transfer area formed by the falling film enhances thermal efficiency, and the short residence time of the feed liquid (usually a few seconds to tens of seconds) effectively protects the effective components of heat-sensitive materials (such as fruit juice and traditional Chinese medicine liquid). The single-effect design process is simple, the energy consumption is relatively stable, and the operation is easy to control.

It is widely used in various fields such as food (juice, dairy concentrate), medicine (concentration of traditional Chinese medicine extracts), and chemical engineering (wastewater treatment, solution purification), and is particularly suitable for the concentration of heat-sensitive and easily scaling materials.
