MOLECULAR DISTILLATION

Molecular or short-path distillation is used to obtain:

• Colorless products,
• More stable product because of the elimination of heavy constituents (acids, colorings),
• More delicate notes because of the increase of the percentage of the aromatic parts of the oil.

Because of the strong vacuum (from to 10 -3 to 10 -6 PSI) the boiling point and extraction time are highly reduced, thus preventing the loss of some heat-sensitive notes in the oil.

The product to be processed is combined with a heavy and light solvent and then is passed through the short-path evaporator; the most volatile parts are condensed with light solvents on a so-called "finger" in the middle of the evaporator and then recuperated as a first distillate. (See figure 8.)

The other parts are condensed on the walls of this first short-path evaporator and pumped into a second evaporator. There again, other parts of the oil are concentrated on the inner ''finger" and recuperated as a second distillate.

Residues and heavy solvent are condensed and recuperated in the residue tank. See picture below for details.
