The present invention discloses a gradient sub-boiling distiller and a distillation method. The gradient sub-boiling distiller includes a condensation pipe, an evaporation surface, a heating device, a liquid distributor, a tail liquid trough, a condensate trough, a tail liquid pipe, a liquid inlet pipe, a condensate pipe, and a shell.
