Supercritical CO2 Neem Oil Extraction Machine


● This system is multi-function SPE equipment, the working mode is intermittent or continuous way to extract solvent from solid or liquid material, the additive can be add to the supercritical fluid;

● The system has one extractor and two separators;

● The highest working pressure of solid extractor is 50Mpa, the highest working temperature is 85°C;

● The design of pressure vessels according the related national standard and rule demand and with over pressure protection system which means enough safety valve;

● The whole equipment beauty, safety and easy operation, pressure temperature flow number can be showed from pressure meter and digital instrument. The material of pipe parts, valves, pipe lines, are all stainless steel(0Cr18Ni9Ti).


Neem Oil Extraction Machine is a kind of green separation technology which separating solute from solid or liquid material by using supercritical fluid solvent.

Neem Oil Extraction Machine is a perfect solvent:

● It has good permeabilityand low viscosity as gas;
● It has close density and fine solution capacity as liquid;
● Solution capacity depend on the density, pressure and temperature of solvent.
So the principle of SCFE is by changing the density, pressure and temperature of CO2 solvent to extract different solute from solid or liquid material.
