? Based on animal fat oil compare extraction methods between pressing /cooking/traditional solvent /supecritical co2 fluid extraction/subcritical extraction

Subcritical fluid extraction (SFE) uses subcritical fluid as extractant. In a closed, oxygen-free, low-pressure pressure pressure vessel, according to the principle of similar solubility of organic matter, through the molecular diffusion process of extraction material and extractant in the soaking process, the fat soluble components in solid material are transferred to liquid extractant, Finally, a new extraction and separation technology of the target product was obtained. Compared with other separation methods, subcritical fluid extraction has many advantages, such as non-toxic, harmless, environmental protection, non pollution, non thermal processing, non destruction and non oxidation of the active components of the extract, large capacity, large-scale industrial production, energy saving, low operation cost, and easy separation from the product.

The method of extracting coffee oil from coffee residue by ultrasonic subcritical fluid extraction technology is to dry the coffee residue and extract the solvent according to the material solution ratio of 1:1 ~ 1:3kg / L, under the extraction temperature of 20 ? ~ 60 ?, extraction pressure of 0.2 MPa ~ 0.6MPa, ultrasonic frequency of 15KHz ~ 30kHz, and under the condition of avoiding light, carry out ultrasonic subcritical combined extraction for 30min ~ 60min; The invention adopts ultrasonic subcritical combined extraction to effectively and completely extract the active components of coffee residue and significantly improve the yield of coffee oil products; At the same time, the active ingredients in coffee grounds are not destroyed; The solvent can be recycled, reduce solvent loss, save cost, and the product has no solvent residue. It is suitable for the actual needs of large-scale industrial production

It has been widely used in special edible oil, vegetable protein, fine chemical industry, natural pigment, medicine, food and other industries. More than 40 projects have been built in China. The main component of subcritical extraction solvent is liquefied butane or propane. The boiling points of the components in the solvent are mostly below 0 ?. The boiling points of butane and propane are - 0.5 ? and - 42.1 ?, respectively. The basic principle of the process is as follows: under normal temperature and certain pressure (0.3mpa-1.0mpa), the oil material embryo is leached with the solvent countercurrent, then the solvent in the mixed oil (or extract) and meal is vaporized under reduced pressure, and the vaporized solvent gas is condensed and liquefied by the compressor before recycling.At present, the extraction methods for  oil extraction machine mainly includes pressing method, cooking method, traditional solvent disllation method, supercritical CO2 method and subcritical solvent extraction method.
