10L * 2 supercritical extraction machine and CBD oil short distillation separation equipment. Two extraction kettles can extract separately or at the same time. A large amount of carbon dioxide gas can be saved in rotation extraction. After one work is completed, the high-pressure carbon dioxide in the extraction kettle can be discharged into the other extraction kettle and continue to be recycled. The weight of 10L extraction kettle is moderate, so one person can operate the machine and replace the raw material barrel, saving manpower. Short range distillation and rotary distillation equipment can complete the purification and separation of crude oil, and finally get pure CBD oil. Our short-range distillation equipment has the functions of raw material preheating, automatic feeding and discharging, and enhanced vacuum automation. It can quickly and efficiently complete the extraction, separation and purification of hemp oil. It is suitable for small and medium-sized production units. The installation and debugging can be completed with online help.
