cbd extraction process

  Studies have shown that if cannabinol is used reasonably in medicine, it has anti-epilepsy, anti-psychotic, anti-depressant, analgesic, reducing the nausea caused by chemotherapy and treating 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:

  1. 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.

  2. 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.

  3. 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.
