Supercritical CO2-Deoiling Process of Soy Lecithin


CO2 Extraction Machine Buyer’s Guide

As you can imagine, not all supercritical CO2 extractors are made the same.
For more than 30 years, we have customized many CO2 extraction machines (Tabletop CO2 Extractor) for many companies and university laboratories (1 lb CO2 extractor). Because each customer’s CO2 extraction process requirements are different, there are almost no identical machines.

How many liters of CO2 extraction vessels are needed?

The first factor that determines the size of the CO2 extraction vessel is the daily working hours of the plant, which determines the daily extraction batch. The vessel size of the CO2 extractor depends on the biomass to be processed per day.

How many pressure is best for your CO2 extraction process requirements?

The choice of CO2 extraction pressure is a changing factor. If the extraction pressure is too high, the useless substances in the plant will be extracted, such as wax and chlorophyll. If the extraction pressure is too low, the extraction time will be increased.

Phospholipids are the general term for lipids containing phosphate roots.

The main components are phosphatidylcholine (lecithin), phosphatidylethanolamine (cephalin), phosphatidylinositol (inositol phospholipid), phosphatidic acid and phosphatidylserine.

Phospholipids are an indispensable component of animal and plant tissues and one of the basic materials of biofilms.

Biofilms are not only a protective barrier for cells, but also important structures for the synthesis, metabolism, and transportation of life substances. Phospholipids are guaranteed by their regular structure and properties. The normal structure and function of cells are the basic materials of life.

Phospholipids are also an important substance for the formation and transmission of nerve information in the brain, accounting for 30% of the brain’s weight. Phospholipids play an emulsifying role in the blood, which can effectively dissolve cholesterol and make it suspended in the blood, avoiding deposition and ensuring normal blood circulation. Phospholipids can dissolve and eliminate lipid peroxides in the body and activate cell functions.

Due to the above functional properties of phospholipids, phospholipids have the effects of regulating blood lipids, improving memory, and delaying aging. At the same time, it has no toxic side effects, and it is a kind of health medicine with great development prospects.

This is a preliminary one-time test. Our purpose is only to prove that the oil in lecithin can be removed by the SFE method.

In the test, we adopted a special process, which can make the test effect better.

Of course, in actual production, we need more tests to achieve the best deoiling effect.

Technically speaking, it can achieve 100% oil removal.

Process parameters

Extraction pressure: 21 MP
Extraction temperature: 45°C
Separation pressure: 6.5 MPa
Separation temperature: 60°C
Extraction time: 70 min
