Why is ethanol used as solvent for extraction
Ethanol is widely used as washing solvent in many equipment, so many people must have a question about “Why is ethanol used as solvent for extraction”. First of all, ethanol has a very good solubleness, which makes ethanol be able to dissolve with so many sample materials such as cbd. Secondly, the boiling point of ethanol is quite low, so ethanol is easy to be separated from the mixture and can save energy at the same time. Therefore, ethanol is always used as solvent for extraction.
Ethanol extraction equipment
There are several ethanol extraction equipment, for example, closed loop extractor, industrial centrifuge, falling film evaporator and some other equipment.
Closed loop extractor is a full-set ethanol extraction equipment, which means closed loop extractor can do the work that several devices do together. For example, users put dried hemp leaves into closed loop extractor, then they can get cbd. Closed loop extractor can do extraction, distillation and other work.
Industrial centrifuge has a quite high efficiency on extracting substances from the mixtures, which is to separate liquid and solid. The working principle of industrial centrifuge is to separate different substances by centrifugal power. Different substances with different weight will be transferred into different places.
Falling film evaporator is a separation equipment that has a high efficiency on evaporating or concentrating substances, especially heat sensitive substances. The materials will be divided into thin films during the evaporation process, which improves the working efficiency a lot.
