CBD solvent extraction equipment

    Cannabidiol (CBD), a highly valuable non-psychoactive compound found in industrial hemp, is widely used in medicine, food, and skincare products. Currently, the mainstream extraction technologies include solvent extraction and supercritical CO₂ extraction. Among these, the solvent extraction method has become the preferred choice for industrial production due to its advantages of low cost, high efficiency, and scalability.

1.Cost-effectiveness: Low equipment investment and solvent costs, ideal for large-scale production.

2.Rapid Processing: Ethanol ensures efficient extraction with shorter processing times.

3.Versatility: Simultaneously extracts multiple cannabinoids and terpenes, enabling the development of full-spectrum or broad-spectrum oil products.

    The solvent extraction method uses organic solvents (e.g., ethanol, heptane) to dissolve target compounds from the plant material, followed by multi-step purification to obtain high-purity CBD. The key steps include:

1.Pretreatment: Raw materials are crushed and dried to disrupt the cellular structure, enhancing extraction efficiency.

2.Solvent Soaking: The material is soaked in a solvent such as high-purity ethanol to dissolve CBD and other cannabinoids.

3.Filtration and Separation: Liquid extract is separated from plant residue via centrifugation or pressure filtration.

4.Concentration and Desolvation: Solvents are removed using vacuum evaporation or molecular distillation, achieving a recovery rate exceeding 95%.

5.Refining and Purification: Impurities are removed through chromatographic column separation, crystallization, and other processes to yield CBD crystals with >99% purity.
