Whole Line Cannabis Supercritical CO₂ Extraction and Purification Technology Device

Introduction

This set of technical solutions mainly adopts the supercritical extraction + molecular distillation + supercritical simulated moving bed process route. The entire process route mainly uses supercritical CO₂ as the solvent. Since solvent conversion is avoided, users can obtain higher quality and higher output CBD product, while greatly reducing the amount of solvent and padding, and minimizing costs.

After the pre-extraction process, like drying, milling, and decarboxilation, we use the supercritical CO₂ extraction device to extract crude oil from materials, and remove the impurities by short path distillation, winterization, and filtration to get high concentration CBD, and then use the supercritical simulated moving bed (SF-SMB) to remove THC and get the final product.

Users can customize the equipment according to the content of CBD in raw materials, your planning processing capacity, and other production plans.

Features of supercritical CO₂ extraction device

Supercritical extraction is the main extraction technology of industrial hemp in the world. This technology uses high pressure and low temperature supercritical CO₂ as a solvent to extract CBD components from hemp. Even though it means relatively high investment and a relatively longer production cycle, it has the following advantages:

1) The extraction efficiency is high: the extraction time of a single pot, including extraction and separation, is about 1.5 to 2 hours;

2) The extraction cost is low. CO₂ is used as the solvent, which can be recycled, so the cost is mainly of electricity.

3) The extracted product has a high CBD concentration, which makes it easier for subsequent purification and separation;

4) Supercritical extraction CBD has higher quality, better market acceptance and higher price;

5) There is no alcohol solvent involved in the extraction process. The factory does not have to be explosion-proof factory, which reduces the regulatory requirements and operates more smoothly and reliably.

The molecular distillation equipment is customized according to the characteristics of the CBD. The yield can reach more than 90%; according to the content of the raw materials, more than 60% of the CBD concentrate can be obtained.

The supercritical simulated moving bed is the most advanced chromatography technology. The equipment is mainly composed of two parts, the simulated moving bed system and the supercritical CO₂ system. It is mainly used for the separation of THC. Compared with traditional chromatography technology, it has the following advantages:

1) The use of supercritical CO₂ as the mobile phase can reduce the amount of solvent to 10% of traditional solvents;

2) The loss of the stationary phase is extremely low, which greatly reduces the operating cost;

3) Continuous industrial production can be performed, which is more efficient than chromatography production of the same specifications;

4) Technical support is available.
