Lifting membrane plate evaporator

The lifting film plate evaporator innovatively combines the principles of rising film and falling film. The feed liquid is first rapidly preheated and evaporated in the lower rising film section, and then enters the upper falling film section to complete the low-temperature concentration. It combines the advantages of efficient start-up of rising film, anti-scaling and gentle evaporation of falling film with high efficiency. It is particularly suitable for wide-range concentration treatment of high-viscosity or heat-sensitive materials. The equipment is compact and highly adaptable.

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).

Why choose our lifting membrane technology?

Unparalleled adaptability

One set of equipment can handle a wide range of materials from low viscosity to high viscosity, without the need to replace equipment at different production stages.

Outstanding energy efficiency

The combination of high turbulence in the rising film section and efficient heat transfer in the falling film section makes the overall thermal efficiency far exceed that of single-mode evaporators, significantly reducing operating costs.

Outstanding anti-scaling ability

The high-speed steam flow in the rising film section has a continuous self-cleaning and scouring effect on the plates, which can effectively delay scaling and extend the cleaning cycle.

Excellent protection for heat-sensitive products

The material passes rapidly through the rising film section and undergoes low-temperature evaporation in the falling film section. The total residence time is extremely short, perfectly preserving the active ingredients, flavor and color of the product.

The equipment is compact and has a high return on investment

Integrating the two functions into one, compared with installing two separate devices, greatly saves floor space, initial investment and installation costs.
