Supercritical co2 extraction machine, system,for Aloe Vera & Essential oil

Pilot scale supercritical co2 extraction systems

Extraction kettle:Material: 0Cr18Ni9;

Volume: 5L 2 set;

Maximum working pressure: 50MPa.

Separation tank:Material: 0Cr18Ni9;

Volume: 2L,2L 2sets;

Maximum working pressure: 30MPa.


HA220-50-10C is very popular in small factories.

It has 2 extraction kettles with a capacity of 5L, and the designed maximum pressure is 50MPa. The two extraction kettles work alternately. After each extraction, the excess CO2 in the extraction kettle can be transferred to another kettle, thereby saving CO2.

The high-pressure valve adopts the Emerson 1700 series and the reliable and stable high-pressure pump

Supercritical fluid is a kind of non-gaseous and non-liquid state between gas and liquid, which can only exist when its temperature and pressure exceed the critical point. Supercritical fluids are dense, similar to liquids, and their viscosities are close to gases. Therefore, supercritical fluid is an ideal extractant.

Huaan can flexibly configure one: 1L+10L (10L -100L)supercritical fluid extraction pilot system ( Equipment pictures ) , which enables feasibility study, process development, parameter amplification, and pilot production to be completed in the same unit without additional investment.
