During the molecular distillation process of the primary main evaporator 21, if there are some impurity components such as water vapor in the mixture, the impurity components will be evaporated together with the light components. At this time, the two groups of primary cold wells 23 condense and adsorb the water vapor, and the water vapor flows into the primary cold well collecting bottles 24, so that the water vapor is effectively isolated and disposed. In this way, the impurities are prevented from entering the subsequent separation process, and the purity of the final product is further improved. At the same time, the first mounting bracket 11 is provided with a first feed bottle 29 connected with the primary main evaporator 21. The first feed bottle can provide the primary main evaporator 21 with the mixture raw material to be separated.

[0028] Please refer to as Figure 2As shown in the figure, one set of primary cold wells 23 is connected with the primary main evaporator 21 through the second pipeline. When the mixture in the primary main evaporator 21 is evaporated under the action of heating, the impurity components such as water vapor generated will be absorbed and condensed by the set of primary cold wells 23 connected therewith.

In the molecular distillation process, if the vacuum degree is not properly controlled, the heat-sensitive materials are prone to metamorphic or degradation in the high-temperature environment. With the intervention of the molecular pump 13, the entire distillation chamber can be ensured to be in a proper vacuum state, avoiding such a situation.

When the mixture is distilled and separated in the secondary main evaporator 31, if there is some water vapor in the mixture, the two sets of secondary cold wells 36 can absorb and condense these impurity water vapors, so that they flow into the secondary cold well collection bottle 40 along the pipeline, thereby being isolated from the subsequent separation process. The bottom of the secondary main evaporator 31 is provided with a secondary light component discharge pipe 34 and a secondary heavy component discharge pipe 35.
