Essential Oil Distiller

 This machine is usually used to extract the essential oil from flowers, plants, citrus, leaves, wood, resin, etc.

The machine consists of an extraction part, cooling part, oil-water separation part, storage part, electric control part.

1.  Extraction part:

The raw material will be loaded into this tank for extraction, which by steam distillation or water distillation to extract. And the extract tank has a material basket, the staff can put the material in the basket in the extraction tank. When the extraction finished, the staff just needs to take out the material basket to remove the material. 

2.  Cooling part:

The steam passes through raw material and vaporizes oil, mixtures of steam and oil vapors go into the condenser, after the cooling, oil formed. The outer wall of the condenser is protected by stainless steel, and the internal part is composed of multi-layer coils, so as to achieve better cooling effect.

3.  Oil water separation part: 

When oil formed, it passes through the oil-water separator to separate the pure oil and pure dew through the different density of water and oil. We can see clearly the result of the separation.

4.  Storage part:

When the oil and water are separated, the separated dew is stored in the tank. It's easier to see where he's stored through a mirror. And we can recycle it.

5.  Electric control part:

This machine is controlled by the electric cabinet. If you use the boiling way with the material, the electric cabinet will heat the heat conduction oil first, then pass the temperature to the water and material to produce the essential oil. This is more controllable and safer than direct heating.

Working description of CO2 system:

CO2 enters the condenser from the steel cylinder and is filled into the CO2 storage tank. The liquid CO2 in the CO2 storage tank is pumped into the heat exchanger by the CO2 main pump and heated by the heat exchanger, so that the CO2 phase changes into a supercritical state and meets the requirements of the process flow. The supercritical CO2 enters the extraction kettle from the bottom of the extraction furnace and fully contacts with the material, and the material is extracted in the extraction kettle.

The extracted mixture and CO2 from the top outlet of the extraction kettle, through the high-pressure control valve at the outlet of the extraction kettle, enters the primary separation kettle for analysis. The process conditions of the first stage separation kettle were controlled to separate the extraction mixture. The analyte was removed from the bottom of the separation vessel.

The extraction mixture that does not meet the analytical conditions is regulated by the high-pressure control valve at the outlet of the primary separation kettle to enter the secondary separation kettle. The process conditions of the secondary separation kettle are controlled, and the extraction mixture is analyzed and separated again. The analyte was removed from the bottom of the separation vessel. Finally, the gaseous CO2 is filtered into the condenser through the filter. After condensation, the gaseous CO2 becomes liquid and enters the CO2 storage tank for repeated circulation extraction.
