Supercritical CO2 Extraction Machine
How to process CBD oil? The steps to make CBD oil, process of extract CBD industrial hemp or cannabis oil.
CBD(cannabidiol) is a chemical in cannabis sativa plant materials, also known as cannabis or hemp, which can relieve pain, reduce anxiety and depression, alleviate cancer-related symptoms, reduce acne, have neuroprotective properties, benefit heart health, and also many other potential benefits.
CBD oil extract from cannabis or industrial hemp/CBD extraction machine
There are many extraction methods to extract CBD oil from hemp or cannabis, like supercritical co2 extraction equipments, ethanol extraction systems, butane extraction, etc.
The most commonly and effectively used way is by using Supercritical CO2 extraction machine.
Supercritical CO2 extraction systems, which by using CO2 as solvent for plant materials extraction, extract oil from plant materials in the setting temperatures and pressures, CO2 can be cycled in closed loop state.
Carbon dioxide, for short, CO2, is considered as a clean, pure, easy get and non-toxic solvent for plant materials extraction, because there is no residue after extraction in the extracted oil.
Careddi Supercritical CO2 Extraction Machine, which made by Stainless Steel 304 or Stainless Steel material, can also meet GMP standard, have win high reputation in buyers around the world.
Careddi has abundant experience in hemp oil extraction, including precision extraction solutions, we have many successful projects in CBD hemp oil extraction, to get high quality CBD oil or CBD isolate.
First, by using supercritical co2 extraction machine, to extract dried hemp powder, to get CBD paste, or called CBD crude oil, and with post processing can get CBD full spectrum oil or CBD isolate.
Winterization, by using ultra-low temperature freezer, is a process to remove undesirable elements (for example, fats, waxes, and lipids) in CBD paste or CBD crude oil, which extracted by supercritical co2 extraction machine.
Mixing CBD crude oil with ethanol or alcohol in a certain rate, stirred vigorously until completely mixed, and place in ultra-low temperature freezer for 24hours, can get a cloudy state mixture.
To use filter, remove undesirable elements.
Put filter paper in the filter machine, and by vacuum pump, the needed oil(CBD oil and ethanol mixture) will go through filter paper into a container, while the undesirable elements will leave in the filter paper, like a cake.
Ethanol Removing and recovery
This step, to remove and recovery ethanol from CBD oil after filtration.
Put the CBD oil into rotary evaporator, and in certain heating temperature and evaporation, ethanol will be remove from CBD oil, and be recycled in another container, the recycled ethanol can be reused, this step, can save and recycled a lot of ethanol.
Short path distillation
To get high purity, high valued CBD full spectrum oil, by using short path distillation equipment, or also called molecular distillation equipment.
Further refine CBD oil, oil goes through Short Path Distillation, after heating, each compound is then separated, because each compound has different boiling point. In this way, each compound can be separated, we can get CBD full spectrum oil.
HPLC system to separate THC from CBD oil
A lot of focus is given to separate THC from CBD oil.
THC (tetrahydrocannabinol), is another cannabinoid derived from hemp or cannabis plant.
Different from CBD, THC has psychoactive effects, and that lead to its status as a controlled substance in many countries worldwide.
THC can produce a sense of euphoria, or a "high" in the brain.
The limit for THC content in cannabis-derived products is currently 0.2 % in EU countries, 0.3 % in Canada and set at similar levels around the world, meaning that removal of THC from CBD is a requirement for commercialization.
After research, Careddi found that by using HPLC system, we can remove THC from CBD oil.
How to make CBD powder? CBD isolate or CBD crystal
CBD isolate is a crystalline solid or powder comprising pure. The process leaves behind pure CBD in crystal form, or powder state, to make CBD easier to consume.
Agitated Nutsche Filter Dryer, is high quality equipment designed for solid-liquid separation process, by filtration under pressure and vacuum drying, for the pharmaceutical, chemical, fine chemical and food industries, which can be used for CBD isolate processing.
