Lifting membrane plate evaporator

Working Principle of lifting film Plate Evaporator

The lifting membrane plate evaporator ingeniously integrates two highly efficient evaporation modes within a single unit, achieving seamless and coordinated operation.

The first section: Rising film evaporation
Location: Lower part of the equipment.
Process: The liquid material enters from the bottom and is rapidly heated to boiling. The high-speed steam bubbles generated pull the liquid, forming an upward-moving liquid film in the plate channels, completing the initial evaporation and strong flushing. It is particularly suitable for handling high-viscosity or easily scaling materials.

The second section: Falling film evaporation
Location: Upper part of the equipment.
Process: The material pre-concentrated in the rising film section is redistributed at the top and forms a thin liquid film that descends uniformly on the surface of the plates by gravity. At this stage, the material is gently and efficiently concentrated to the target concentration at a low temperature and within a short residence time.
Core value: First, break the deadlock by leveraging the "strong" power of the rising film, and then, with the "gentle" essence of the falling film, achieve perfect adaptation to the characteristics of complex materials (from low viscosity to high viscosity).
