The falling film concentrator is mainly composed of a shell and tube heater efficiency, evaporation chamber, and concentrator, condensation cooler, vacuum of solvent recovery tank.

1, the material is by the column tube into the upper and the material distribution device evenly into each root canal and form a thin film along the tube surface. By dividing wall heat transfer, material to boiling, boiling gas drive liquid high-speed flow down, into the vapors liquid separator, the product is able to concentrate.

2, heat transfer coefficient has been further improved, material residence time is shorter, and evaporation temperature is lower.
