Industrial extraction method of cannabidiol

A method for industrial extraction of cannabidiol, characterized by comprising the following steps:

• step one, crushing hemp flowers and leaves and subjecting the crushed hemp flowers and leaves to heating and tossing or drying treatment at 100-150° C.;
• step two, subjecting the crushed hemp flowers and leaves after the drying treatment in step one to solvent extraction, and concentrating the resultant extract solution to a certain amount remaining;
• step three, adding other solvents into the concentrated solution obtained after treatment in step two for liquid-liquid extraction;
• step four, separating the resultant lower liquid after the treatment in step three, and adding activated carbon for stirring to decolorize;
• and
• step five, concentrating the decolorized liquid obtained after treatment in step four, and deodorizing to obtain a cannabidiol-rich oil paste.
