1 pound CO2 extraction machine

It’s a 1-pound CO2 extractor and comes with a 2L CO2 extraction vessel (the material basket vessel is 1.7L), which will process about 1 pound per run with 12 runs per day. Therefore, it can also be called a 1.7L supercritical CO2 extractor in BIT company…

2L Supercritical CO2 Extraction Machine

Customized for people who study supercritical CO2 extraction process technology to a broader field of analysis and processing. In addition to many industrial uses, it is also suitable for various colleges and universities. At the same time, it can be used in teaching laboratories and precision research.

1 pound CO2 extractor

This CO2 extraction machine can meet the needs of your CO2 extraction process experiment in the laboratory.

It’s a 1 lb CO2 extractor and comes with a 5 L CO2 extraction vessel, which will process about 1 pound per run with 12 runs per day.

The L-02 CO2 Extraction Equipment is one of the most common models in CO2 extraction process laboratories, it means that it can work in the extraction capacity of 1lb of dry material per batch, which is very important for the work of the laboratory because you can use it to carry out small experiments, prove that the extraction data is reliable, and prepare for large-scale commercial or industrial production.

At the same time, we have equipped it with high pressure of 500bar. Of course, you can also order a higher gas pressure to 1050bar to meet a wider range of CO2 extraction process experimental requirements.

Supercritical CO2 Extraction of Peppermint Oil
Supercritical CO2 Extraction of Peppermint Essential Oil

peppermint co2 oil

The dry aerial part of peppermint, a plant of the Lamiaceae family, whose volatile oil has a strong refreshing fragrance and is good medicine. It has the functions of dredging wind, heat dissipation, expectorant, detoxification, bacteriostasis, and anti-oxidation. It is used to treat wind-heat, colds, and headaches. , Red eyes, sore throat, toothache, etc. For peppermint volatile oil, the traditional extraction method is mostly steam distillation. Due to the high temperature of the method, it is easy to decompose some heat-sensitive components, and the oil yield is low.

Features of peppermint CO2 oil

This excellent CO2 extraction of peppermint leaves is a useful alternative to standard peppermint essential oil. Its fragrance is warmer and calmer than the EO and also a little more aromatic, tending toward spearmint.

Indeed, there is less menthol and camphor in the CO2 and more diverse components in the GC readout, pointing to more complexity and depth of character.

Compare the scent of the essential oil, this peppermint CO2 Oil and a fresh mint leaf and you’ll find that the peppermint CO2 extraction oil is vastly more realistic and true to the leaf. So if you’re after a more naturalistic peppermint for your experiments, go for this CO2.

Peppermint Oil CO2 Extraction Process

supercritical CO2 extraction peppermint oil machine is 1L, mint is crushed to 20 mesh, extraction pressure is 15MPa, extraction temperature is 50℃, the CO2 flow rate is 40L/H, separation pressure is 6MPa, and separation temperature 50℃, extraction time is 90min. The extraction rate under this process condition is 3.2%;

Steam distillation

Weigh 200g of mint that has been dried and crushed through a 20 mesh sieve, add 1200mL of water, soak for 60min, distill for 3h, collect the volatile oil, dehydrate it with anhydrous sodium sulfate, and weigh it. The calculated yield is 0.84%. The volatile oil is brown. Liquid with a special fragrance.

CO2 extraction VS steam distillation method of peppermint oil

The ABTS and FRAP methods were used to detect the antioxidant capacity of peppermint supercritical extract, and compared with the antioxidant capacity of peppermint volatile oil extracted by steam distillation. The results showed that the antioxidant capacity of peppermint volatile oil extracted by the supercritical CO2 extraction method was stronger than that of the steam distillation method extracted peppermint volatile oil.
