Studies have shown that if cannabinol is used reasonably in medicine, it is anti-epilepsy, anti-psychotic, anti-depressant, analgesic, and can reduce the nausea caused by chemotherapy and treat asthma. Therefore, many people wonder what is the best cbd extraction method. There are several extraction methods, and the best cbd extraction method is ethanol extraction method. Solvent extraction uses a solvent rather than water to separate the cbd from the plant material. During the process of extracting cbd, there are also some other steps, and the whole process is as follows:
- The hemp plant should be dried at 105-120 degrees Celsius for 0.5-4 hours to obtain a raw material having a moisture content of less than 7%. For this step, users could use mash belt drier to get hemp plant dried.
- Extract cbd from the dried hemp material, and obtain the liquid and residue after extraction . Ethanol is used as the washing liquid to extract cbd out of hemp plant by industrial centrifuge. The liquid is going through throttled of vacuum suction filter to resolve the cbd and then the solvent is recovered.
- Filtration: Get isolated cbd filtered by using an ultrafiltration membrane with a molecular weight cut-off of 80-120 kD. And make filtered cbd flow through UV light to get purified.
Ethanol extraction method of cbd is the most popular used method in industrial, chemical, pharmaceutical and other application fields. Because the ethanol can be used for several times, so this method is more energy-saving.
How is CBD Extracted?
Cbd oil is always extracted by ethanol, Co2, butane, olive oil and some other solvents. Generally, hemp plant or Cannabis plant is always put into extraction equipment to get extracted by solvents. Washing hemp plant or Cannabis plant with solvents can make cbd get extracted efficiently. And separating cbd and solvents by getting solvents get evaporated can provide cbd oil with a better purity. Separating the mixture can guarantee a pure cbd oil up to 98% purity.
How is CBD Oil Harvested
Cbd oil is made from hemp plant or Cannabis plant is through several extraction procedures. There are several processing methods that can be applied for cbd oil extraction, including ethanol extraction method , Co2 extraction method, butane extraction method and some other extraction methods. Cbd oil can be extracted from hemp stems or leaves.
How is CBD Isolate Extraction?
Generally, cbd is extracted by some solvents, which means cbd needs to be separated from the mixture that contains cbd and solvents. Therefore, the mixtures need to be disposed after extracting cbd. And the way to separate cbd and solvents is always to evaporate the mixtures. In the evaporation process, the solvents always get to be evaporated and chilled, in order to get out of the mixtures.
How to Make CBD Oil at Home?
Cbd oil has great benefits for human skin. cbd oil contains fatty acids that have a necessary effect on the skin, which moisturizes the skin and prevents the skin from being dry . cbd oil provides the vitamins and minerals that people need, as well as other substances that people needs.

A lot of people could make cbd oil at home, and next let’s go through the process of making cbd oil:
- Put the dry hemp in a container and take 2 gallons of solvent to strip THC from a pound of dry material, which can strip about 80% of THC plant material.
- The solvent should be added to the mixture again and work for another 3 minutes to extract the remaining THC. Pour the solvent oil mixture through a coffee filter into a clean container. Discard the washed plant material and pour the solvent oil mixture through a coffee filter into a clean container.
- Make rice cooker boil the solvent well and maintains a half gallon solvent mixture. Add the oil mixture to the rice cooker until it reaches about 3/4 capacity.
- When the level in the rice cooker is lowered for the last time, add a few drops of water, which will help to release solvent residues and protect the oil from excessive heat. When there is approximately 1 inch of solvent-water mixture in the rice cooker, place it on the oven, then remove the unit and rotate the contents until the solvent boils. After the solvent boiled, turn the cookware to a low temperature. The oil should not exceed 290°F or 140°C at any time.
- Remove the oil-containing pan from the rice cooker and gently pour the oil into a stainless steel container. Pour hot oil into the bottle as it is drawn into the plastic syringe. The drug can be easily dispensed by placing the oil in a plastic syringe.
