How to make 96%+ Plant Oil ?

High purity plant oil is becomes the new star of health, wellness and beauty industries, demand. How to make high purity plant oil? Lab1st is a professional turnkey solution provider for high quality oil extraction and purification from plant based biomass.

Below is a full flow of plant oil extraction step by step. And distillation is a key module because only high purity oil is what we need to produce related health products.

There are many ways to extract botanical chemical compound from the biomass, the most common way is to use a solvent (ethanol for example) to extract the botanical compound, and then recover the solvent to get a crude oil. To isolate the individual compound, the crude oil needs to be distilled after extraction. After distillation module, you will get 95%+ purity plant oil.

We offer 2 methods to refine the botanical chemical extract, one is molecular/wiped film distillation, and the other is called short path distillation.

What is Short Path Distillation?

Short Path Distillation works in much the same way as (vacuum) steam distillation in that the extract is heated and each compound is then separated because each one has a different boiling point. By heating the distillation flask uniformly and by vacuum pumping, the evaporation flask is brought into a negative pressure state, the boiling point of the solution is reduced, and the evaporation speed is accelerated. 

It is especially suitable for the separation and purification of temperature sensitive materials and those compounds that have been thermally decomposed, oxidized or polymerized before the boiling point is reached during atmospheric distillation. 

With short path distillation, we could get 90%+ purity plant oil.

Short Path Distillaiton Kit - SPD Series

  General Features​

  • Various Size Option: 2L, 5L, 10L, 20L.

  • No Gas Leakage: Thermowell design instead of traditional screw adapter, ensuring no gas leakage

  • Continuous Discharging:Discharge valve instead of traditional 1-to-1 and 1-to-3  flask, which helps change the flask during operation and realize continuous discharge

  • Better Vacuum Environment: Using KF25 flange and flexible stainless steel vacuum bellow for better vacuum 

What is Molecular Distillation?

Molecular distillation (Wiped Film Distillation) is a special kind of liquid - liquid separation technology, which relies on the difference of the average free path of molecular movement of different substances to achieve separation.

Material is delivered from a feed flask into a columniform evaporation section, getting heating, on the outside, (circulating hot fluid jacket type), and a slotted wiper mechanism forcing liquid around and downward in a thin film on the inside.

principle diagram of the molecular distillation

In the center of the body is a wiped film evaporator with internal cooling condenser, providing a short path for vapor molecules traveling from the heated surface to the condenser surface. For botanical compounds, the internal condenser fluid must be kept elevated (~80°C) to prevent high viscosity or freeze up distillate and the related components. During the itinerary downward, lighter (lower boiling point) fractions of the liquid begin to vaporize, move to the internal condenser and condense, falling down as a liquid into a vessel that catches and separates the distilled liquid which flows into a receiver flask. Heavier residue material (chlorophyll, salts, sugars, heavy wax fractions) does not evaporate and instead travels through the still body and flows into a different receiver flask.
