Description

‌Complete Production Line Solution for Hemp Supercritical Fluid Extraction:‌

‌Core Process Routes‌

Supercritical CO₂ Extraction

Molecular Distillation

Supercritical Simulated Moving Bed (SF-SMB)

These three integrated technical modules leverage supercritical CO₂ as the core solvent to achieve ‌high-yield, high-purity CBD extraction‌ while precisely removing THC to comply with global regulatory standards.

‌Process Workflow‌

Pretreatment Stage‌

1.Raw material preparation: Drying, crushing, and decarboxylation to optimize supercritical extraction.

2‌.Supercritical CO₂ extraction‌: Efficient extraction of hemp crude oil under low-temperature, high-pressure conditions (1.5–2 hours per batch).

Purification & Refining‌

1‌.Short-path distillation + winterization filtration‌: Removes waxes, pigments, and impurities to concentrate CBD to 60%+ purity.

2‌.Customized molecular distillation‌: Achieves >90% CBD yield while preserving heat-sensitive components.

THC Removal‌

‌SF-SMB chromatography‌: Industry-leading technology using supercritical CO₂ (replacing 90% of traditional solvents) for continuous THC separation. Features ultra-low stationary phase loss and scalable production

the whole line of CBD extraction technlogy process

Advantages‌ of Supercritical CO2 Extraction Device

Solvent-free‌

No explosion-proof design required; simplified regulatory compliance.

Cost-efficiency‌

CO₂ recycling minimizes expenses (electricity is the primary cost). Produces high-concentration CBD for easier downstream purification.

Premium quality‌

Delivers >99% pure CBD with strong market competitiveness.

1-CBD supercritical CO2 extraction plant

The molecular distillation equipment is customized for CBD refinement: Achieves >99% yield and produces 60%+ CBD concentrate (content depends on raw material quality).

2-Molecular distillation devcie

The supercritical simulated moving bed (SMB) is the most advanced chromatography technology. The equipment primarily consists of two components: the simulated moving bed system and the supercritical CO₂ system. It is mainly used for the separation of tetrahydrocannabinol (THC). Compared to traditional chromatography methods, it offers the following advantages:

1‌.Reduced solvent consumption:‌ The use of supercritical CO₂ as the mobile phase reduces solvent usage to 10% of that required by traditional solvents.
2‌.Minimal stationary phase loss:‌ The stationary phase experiences extremely low degradation, significantly lowering operating costs.
3‌.Continuous production capability:‌ It enables continuous industrial-scale operation, making it more efficient than traditional chromatography systems of the same scale.
4‌.Technical support availability:‌ Ongoing technical assistance is provided.
