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.

Abstract: The present invention provides a method for the separation of placenta functional ingredients. By using the supercritical fluid technology, the placenta powder is placed inside an extraction tank, under the predetermined pressure and temperature; the supercritical CO2 solvent is flown into the adsorption tank, in order to deodorize the fishy smell of the placenta powder, and extract the oil of the placenta powder. Under the same operating conditions as mentioned above, the deodorized and extracted placenta powder and supercritical CO2/ethanol solvents are flown into an adsorption tank at the predetermined volumetric flow rate ratio to adsorb the estrogen of placenta powder to get the estrogen-removed placenta peptide extracts. Afterwards, supercritical CO2/ethanol solvents are separated by rapid decompression to get the functional ingredients of placenta powder.

Abstract: An easy stop for outlet poppet, which is composed of outlet end screwed with thread joint of outlet poppet, inlet end screwed with outlet pipe of water storage tank of valve and valve rod put into from inlet end of valve, its features are as follows: positioning flange edge is made in inner middle section of valve, conic-shaped perforation is set in center of positioning flange and front part of valve rod is made as stair-shaped rod so as to provide a push block as clip positioning, the outer ring of its end part is conic-shaped, which is positioned with conic-shaped perforation of positioning flange in middle section of valve, one concave force groove is made at center of its end edge in rod direction; however, when one outlet poppet is screwed with outlet end of valve, this outlet poppet is to press push block and drive valve rod to move toward inlet end of valve so as to form an access inside valve, water is then pushed into outlet poppet from inlet end of valve; if want to dismantle outlet poppet from val
