This utility model discloses a planar film-type
evaporation and
crystallization integrated
machine, belonging to the technical field of
evaporation and
crystallization equipment. It includes: a stirring tank with a lid on top; an
evaporation chamber on one side of the stirring tank; multiple sets of planar evaporation films inside the
evaporation chamber; and a stirring
assembly inside the stirring tank, comprising
bevel gear one,
bevel gear two, and
bevel gear three. This
assembly can stir the solution from different directions and angles, enabling faster and more comprehensive mixing of the
solvent and solution, ensuring uniform solute distribution in the solution, providing a stable material basis for subsequent evaporation and
crystallization, reducing localized crystallization or differences in
crystal quality caused by uneven solution distribution, and allowing for quick installation and removal of the lid. Operators can directly and thoroughly clean the inside of the stirring tank, preventing residual crystals or impurities from affecting subsequent solution
processing.
