Purify cbd extract/extractum, why recommend 3-stage molecular distillation?
CBD extract (extractum)
is a multi-component mixture. Except CBD, it contains dozens or even hundreds of compounds including plant essential oil, plant wax, pigment, water, residual solvent, etc. In order of molecular weight or boiling point, CBD is in the middle segment. -
The function of each stage of three stages molecular distillation
High pressure reactor safety operation
, we need to pay attention to the following points:1. The first stage is used for the separation of water, solvent and other ultra-low molecular weight components in the extract.
2. The second stage: the components in the enrichment section whose molecular weight (boiling point) is less than CBD are isolated.
3. The third stage: the molecular weight (boiling point) of the distillation is close to the CBD enrichment section, which is used for the subsequent extraction of high-purity CBD.
Larger molecular weight of wax, pigment and other residues in the distillation residue.

If use the single-stage molecular distillation device
, the distillation process needs to be repeated three times. In each process, cbd extract (extractum) needs to be heated. The components of plant extract are relatively complex. During the heating process, decomposition and polymerization may occur, forming impure, affect the total efficiency of extraction.Experimental equipment can use a single stage multiple times, which can reduce the early equipment investment. The extraction yield loss and repeated heating cost caused by multiple heating may be much higher than the cost of three stage molecular distillation equipment
input, so it is recommended to use three stage continuous production mode. -
CBD oil distillation one stop solution, include molecular distillation equipment
, supercritical co2 extraction machine, crystallization and dewaxing filtration, wiped film evaporator, rotary evaporator, heating and cooling circulator bath, vacuum pump, spray drying equipment, etc.
