300L CO2 extraction equipment for cbd oil
The best parameters for extracting CBD Oil using a supercritical co2 extraction machine:
Pulverization degree: 40 mesh
Extraction temperature:50-60 °C
Extraction time:120 minutes
Extraction temperature:60-65 °C
Flow rate of CO2:150Kg–200Kg/h
When supercritical CO2 equipment is used to extract CBD Oil, the screened industrial hemp (including leaves, stems and seeds) is first placed in an oven and dried at 50 ° C for 12 hours; then the pre-dried industrial hemp Put it into a grinder to pulverize into 20 mesh industrial hemp powder, put the industrial hemp powder into an oven, and dry it at 50 ° C for 12 hours. The dried industrial hemp powder continues to stay in the drying oven to cool naturally. Normal temperature.
The cooled industrial hemp powder is put into the material tank of the extraction kettle, and CO2 gas is injected into the extraction kettle for extraction. The extraction temperature is 60 ° C, the pressure is 30MPa, and the extraction time is 1.5h. The CBD Oil in industrial hemp powder is dissolved in In the supercritical CO2 fluid, the CBD Oil was extracted from the extraction kettle through throttling to reach the separation kettle, and the CBD Oil was obtained with an oil yield of 4.92%.
2*150L co2 cbd extraction equipment is used for extracting substances (solid or liquid) under high pressure and suitable temperature, and changing the conditions in the separating kettle to resolve the dissolved substances in order to achieve the purpose of separation. The device is mainly composed of extraction kettle, separation kettle, mixer, CO2 high pressure pump, entrainer pump, refrigeration system, heat exchange system, CO2 tank, CO2 level meter, purification system, flowmeter, temperature control system and safety protection device.
