Molecular Distillation System, 190mm, Gongyi Yuhua Instrument Co., Ltd (CAT#: STEM-GME-0143-YJL)

Molecular Distillation System, 190mm, model FMD-200(A) is manufactured by Gongyi Yuhua Instrument Co., Ltd. Molecular distillation is a distillation method operated under high vacuum, in which the mean free path of vapor molecules is greater than the distance between the evaporating surface and the condensing surface, so that the difference in the evaporation rate of the components in the material liquid can be used to separate the liquid mixture.

Effective evaporation area (M2) : 0.35
Condensation area (M2): 0.5
Barrel Inside diameter (mm) : 190
Constant pressure feeding funnel volume (L) : 1.5
Processing flow (KG/H): 1.5∽10.0
Motor power (W): 200
Max Rotation speed (RPM): 300

1. The distillation temperature is low. Molecular distillation is operated at a temperature far below the boiling point. As long as there is a temperature difference, the separation purpose can be achieved. This is the essential difference between molecular distillation and conventional distillation.
2. The distillation vacuum degree is high, and the molecular distillation device can obtain a high vacuum degree inside. Usually molecular distillation is operated at a very low pressure, so the material is not easy to be oxidized and damaged.
3. The distillate film is thin and the heat transfer efficiency is high.
4. The heating time of the material is short, and the distance between the heated liquid surface and the condensation surface is less than the mean free path of light molecules, so the light molecules escaping from the liquid surface reach the condensation surface almost without collision. Therefore, the heating time of the distillation material is short, and the residence time at the distillation temperature is generally between several seconds to tens of seconds, which reduces the chance of thermal decomposition of the material.
5. The degree of separation is higher, and molecular distillation can separate substances that are difficult to separate by conventional methods
6. There is no boiling and bubbling phenomenon, molecular distillation is free evaporation on the surface of the liquid layer, carried out under low pressure, and there is no dissolved air in the liquid, so the whole liquid cannot be boiled during the distillation process, and there is no bubbling phenomenon.
7. It is non-toxic, harmless, pollution-free and residue-free, and pure and safe products can be obtained, and the operation process is simple and the equipment is few. Molecular distillation technology can separate substances that are difficult to be separated by conventional distillation.
8. Molecular distillation equipment is expensive. Molecular distillation equipment must ensure the high vacuum degree of the system pressure. It has high requirements for material sealing, and the distance between the evaporation surface and the condensation surface should be moderate. The equipment is difficult to process and expensive.
9. The energy consumption of the product is small. Due to the low loss of overheating in the whole separation of molecular distillation, and due to the unique structural form of the molecular distillation device, the internal pressure is extremely low, and the internal resistance is much smaller than that of conventional distillation, so energy consumption can be greatly saved.
