Extraction of Wild Rosa davurica Seed Oil by Supercritical CO2 Using wild Rosa davurica seeds as raw materials, a quadratic polynomial mathematical model of the yield of oil from wild Rosa davurica seeds extracted by supercritical CO2 was established by using response surface analysis method through improving the existing supercritical CO2 extraction equipment, and the […]
Supercritical CO2 Extraction
Semi-continuous Supercritical CO2 Fluid Extraction of Peanut Oil and Quality Inspection of Peanut Oil
The optimum extraction conditions of peanut oil by supercritical carbon dioxide (SC-CO2) were studied by semi-continuous method, and the extracted peanut oil was sent to the National Grain and Oil Quality Supervision and Detection Center for detection. The results showed that the optimum technological conditions for SC-CO2 extraction of peanut oil were as follows: extraction […]
Study on Supercritical CO2 Extraction of Chamomile Essential Oil
Study on Supercritical CO2 Extraction of Chamomile Essential Oil Chamomile was extracted by supercritical CO2 and purified by molecular distillation. With the extraction rate of Chamomile essential oil as the index, the effects of extraction pressure, extraction time, extraction temperature and other factors were investigated, and the optimal process parameters were obtained by three factors […]
Supercritical CO2 Extraction Workshop Operation Rules
Supercritical CO2 Extraction Workshop Operation Rules a)The environment should be clean and items tidy. Safe passage is clear without any obstacles. b)Good ventilation in the workshop should be guaranteed to avoid workers’ lack of oxygen led by high CO2 density. c)Chloride ion content in the water used in this system should not be more than […]
