FAQ

Before buying a supercritical CO2 extractor, you must understand the following 7 important questions.

What information do I need to provide before making an inquiry?

A: Raw materials.
B: Daily processing capacity. operating hours. We can customize 0.5L-4500L supercritical CO2 extraction system for you.

What can I use a supercritical CO2 extractor for?

High value-added ingredients extracted from natural substances (natural pigments, essential oils, edible or medicinal)
Such as hop extract, plant essential oils (rose essential oil, grape seed oil, hemp oil, CBD oil), lycopene, capsaicin, lavender essential oil, herbal extracts

What material does your supercritical CO2 extractor use? Does it comply with GMP standards?

The standard configuration is 304 stainless steel, and 316L can be customized.
Yes, our supercritical CO2 extraction machine complies with GMP standards.
Our supercritical micronization machines are even used in the pharmaceutical industry.

What is the maximum gas pressure of a supercritical CO2 extractor?

Lab scale (0.5L-5L): 500bar
Pilot scale, Commeacrcial scale (10L-100L): 400bar
Commeacrcial scale,Industrial grade (150L- ): 350bar
We can order a supercritical extractor with a maximum pressure of 1050bar for you.
Note: The higher the pressure means that the extractor is more difficult to manufacture, the smaller the extraction capacity, the higher the cost. Plants in nature can usually be extracted under a pressure of 300 bar.

Can supercritical CO2 extractors work under supercritical and subcritical conditions?

Can.
Only need to adjust the gas pressure in the CO2 extraction system

Can CO2 be reused? What is its consumption?

Yes it is. CO2 is recycled in the supercritical extraction system.
When the capacity of a single extractor is greater than 30L, we recommend to equip a CO2 recovery system.
The consumption is about 30% of the extracted plants. For example, to extract 10 kg of raw materials, about 3 kg of gas is consumed.

Can we do an extraction test before buying?

Of course, we can extract and test your raw materials and send you videos and pictures
for your information.
