Process overview

Cannabis Oil Purification

Crude extract does not become high-potency distillate in one step. Here is the equipment path B/R builds for it — cleanup, decarboxylation, and high-plate distillation.

The path

Four steps from crude to distillate

Each step removes a class of contaminant that would otherwise cost you potency, colour, or uptime further down the line.

01

Prepare crude

Winterize to drop fats and waxes, filter, and strip residual solvent so the charge is distillation-ready.

02

Wash

Liquid-liquid extraction pulls sugars, phospholipids, and pigments that char in a hot boiler.

03

Decarb

Convert THCA, CBDA, and related acids to active cannabinoids in a vessel built for the CO2 release.

04

Distil

Fractionate on a spinning band column and pull high-potency cuts without repeat passes.

Equipment

The systems that do the work

Three platforms, each mapped to a step in the path. They can be bought as a train or added one at a time.

Liquid-Liquid Extraction

Strip water-soluble sugars, phospholipids, and pigments from crude so distillation runs cleaner with better colour.

Why the path matters

Contaminants removed early stay out of your product

Skipping cleanup does not save time; it moves the cost into the still. Waxes and sugars char on hot surfaces, acid-form cannabinoids fight the vacuum, and both push you into extra passes that cook the product and darken the colour.

  • Fewer passes, so less thermal history on the cannabinoids
  • Lighter distillate colour out of the same crude
  • Longer intervals between system cleanings
  • Repeatable runs you can document for GMP
