Abstract: The present invention provides a device for separating and purifying the collagen Type 2 in chicken bones, comprising a liquid fluid container, a raw liquid container, a membrane separation tank, a mixing tube, two high pressure metering motors, a precooler, two preheaters, a temperature controller, two one-way valves, two inlet control valves and two outlet control valves. The liquid extract of defatted chicken bones discharged from the raw liquid container and the liquid CO2 discharged from the liquid fluid container can be mixed uniformly in the mixing tube, and then fed into the membrane separation tank. The membrane separation tank produces small-molecular-weight peptides and large-molecular-weight collagen Type 2 harmlessly and efficiently.

Abstract: The present invention provides a method of separating estrogen from placenta, which uses supercritical fluid technique to load the placenta powder of human body or sheep, pig, deer and other animals into an extraction tank. Under the operating conditions of preset pressure and temperature, supercritical solvent is added into the extraction tank to extract estrogen from placenta, so as to acquire de-estrogen placenta powder and placenta extract liquor. Under the same condition, the de-estrogen placenta extract liquor and supercritical solvent are added by a preset volume flow ratio into an adsorption tank. The estrogen in the placenta extract liquor is adsorbed by the adsorption tank to obtain de-estrogen placenta extract. It is then eluted with ethanol solution by gradient proportion to obtain purified natural estrogen.

Abstract: The present invention provides a method to separate and purify functional ingredients in placenta using supercritical fluid technology, where, placenta extract liquid and supercritical CO2 solvent are guided into a fractionation tank constantly in a preset velocity at a preset temperature and pressure to extract peptides, proteins and other functional ingredients. And then, the solution is conveyed through the three fractionation tanks at a preset temperature and depressurized gradually to separate, fractionate and purify the content of placenta peptide and protein, so as to obtain the high purity of peptides, proteins, active factors and other functional ingredients.
