Embodiment 1
[0021] Example 1: Such as Figure 1 As shown, the present invention provides a solvent separation method for plant extraction mixtures, comprising the following steps:
[0022] S1, the overall evaporative concentration: the extraction mixture is added to the concentration tank, heated evaporation concentration, mixed steam flows out from the top of the concentration tank, and the bottom product is extractant;
[0023] S2, overall condensation: the mixed steam through the heat exchanger after the overall condensation into the distillation tank;
[0024] S3, distillation: add hot water to the sandwich of the distillation tank, evaporate and separate the organic solvent from the water, the solvent vapor flows out from the top of the distillation tank, and the solvent vapor is condensed through the heat exchanger and then introduced into the separation tank;
[0025] S4, solvent stratification: add saturated sodium carbonate solution to the separation tank, after the shock layering, t...
