DigiVac for Distillation

DigiVac for Distillation & Processing | DigiVac makes a wide variety of products for use in distillation, including short path, wiped film, and thin film.

Short Path Distillation Summary

Short path distillation is a process that occurs after extraction. It is a type of botanical processing, generally utilized for the molecular separation of botanical fluids to achieve high potency. “Short path” refers to the short distance the oil travels, relative to the notoriously large industrial distillation units most people know. Wiped film distillation is a type of short path distillation.

Vacuum for Short Path Distillation

One of the primary purposes of using vacuum in distillations is to lower the temperature required to achieve a boiling point. The target product in a distillation could either be the remaining product, the distilled product, or a purified product. The vacuum associated with a distillation depends on the product to be distilled. Volatile substances are likely to undergo vacuum distillations above 1 Torr. Composite distillations typically require precise pressure control in the region above 1 Torr.

DigiVac for Distillation | Solvent Recovery

Solvent recovery is the process of extracting target products from waste or by-product solvents generated during the manufacturing process. These chemicals can then be repurposed. Solvent recovery can be done by several methods including fractionation, azeotropic distillation, and rotary evaporation.

The botanical processing market uses three main extraction techniques CO2, liquefied hydrocarbons, and ethanol extraction. In all processes, the plant material is subjected to a solvent to remove active compounds from the plant matter and filtered to yield a solution of the solvent with plant extracts. All extraction methodologies yield an oil once the solvent has been removed. This oil contains plant lipids, possibly chlorophyll, waxes, fats, and terpenes. The resulting ethanol solution is concentrated via vacuum distillation. The solvent-free, purified extract can be dried on trays in a vacuum oven to yield a yellow to amber extract.

We are knowledgeable of a variety of botanical and R&D processes, such as solvent recovery. If you have a need for a vacuum instrument for a process not mentioned here, we will work with you to meet your needs.
