Super Critical Liquid CO2 Device For Essential Oil Extraction

Supercritical co2 extraction adobt Co2 as solvent to Get Best Extraction and Separation Effects Under Super Critical Condition.

CO2 has many predominant characteristics compare with traditional solvent-extraction process: innocuity, smelless, incombustible, free from corrosion and residues, circulating, little energy cost during state changing, easy to operate at ordinary temperatures. etc.

Our Supercritical CO2 Extraction plant can separate the active ingredients from the raw material easily and selectively, energy-saving and Environment-friendly. The extractive and essential oil are widely used in food additive, cosmetic, medicine and many other fields. Such as extract smell from flowers for perfume, extractive from spice for medicine and essential oil from crops for food industrial. etc.

The supercritical CO2 extraction device designed by our company, adopt advanced technology, such as CO2 main system, refrigeration system, hot water constant temperature system, CO2secondary system , air elimination and clean system and automatic control system etc., which up to the advanced levels in the world.

1.CO2 main system, namely CO2 circulatory system: In the system, carries on the extract and the separation to the material, this system consists of the high pressure and medium-pressure vessels. the equipments including: 1) Extract autoclave:Used for extraction as main equipment, The full bore fast open structure makes the operation time of cover open /close in 1 minute. A material basket in autoclave is applied for loading and unloading. In the basket, the precise durable filtrating device can prevent the material access in pipe and other equipment.

2) Separation autoclave: It is used in separating material by the system may consist of 1 autoclave or 1 column 1 autoclave or 2 autoclaves, or according to the user request.

2.Heat exchanger:The primary functions of Heat exchanger are:

1)To ensure the temperature of CO2 achieves the extract temperature and separation temperature.

2)To ensure the CO2`s liquefaction.

3)To ensure the CO2 can enter in the high-pressured CO2 pump to carry on the circulation, this system has 4 heat exchangers. CO2 high-pressure pump:building up the pressure of CO2 to enable its pressure achieves the extraction pressure, the top pressure limits to 45MPa. The velocity modulation system is equipped for flow control, and it is equipped with level 3 overpressure protective measure.

4)CO2 buffer tank:for liquid CO2.

5)CO2 storage tank:CO2 storage.

2. Refrigeration system:

3.Hot water constant temperature system:

4.Electric instruments control:

5.Safty:

6.CO2 secondary system:

7.Air elimination and clean system.
