Embodiment 1
[0036] Supercritical fluid extraction method A: put 2.5kg of blood dried blood powder after crushing and sieving into the extraction kettle, and the extraction solvent carbon dioxide is replaced by CO 2 Cylinder discharge, filtered, storage tank, in CO 2 After being cooled and liquefied in the storage tank, the high-pressure pump is used to increase the pressure to the set extraction pressure of 20MPa, so that the CO 2 Become a supercritical fluid state, CO 2The flow rate of supercritical fluid is 30kg / h. Under a certain extraction pressure, it is heated to the set extraction temperature of 45°C through a heat exchanger, and then sent to the extraction kettle to contact with blood dried blood powder for dissolution and extraction. The carbon dioxide fluid and the extract enter the separation tank I together for the first-stage analysis. The analysis pressure is 7MPa and the temperature is 60°C. After the first-level analysis is completed, the three-way analysis valve of the ...
Embodiment 2
[0038] Supercritical fluid extraction method B: put 2.5 kg of blood dried blood powder after crushing and sieving into the extraction kettle, and extract solvent carbon dioxide by CO 2 Cylinder discharge, filtered, storage tank, in CO 2 After being cooled and liquefied in the storage tank, the high-pressure pump is used to increase the pressure to the set extraction pressure of 20MPa, so that the CO 2 Become a supercritical fluid state, CO 2 The flow rate of supercritical fluid is 30kg / h. Under a certain extraction pressure, it is heated to the set extraction temperature of 45°C through a heat exchanger, and then sent into the extraction kettle to contact with the dried blood fine powder; at the same time, the methanol in the organic solvent storage tank is pumped into the extraction kettle through a high-pressure pump to serve as entrainment. Agent, according to requirements, adjust the flow ratio of methanol entrainer and carbon dioxide fluid, generally 15%. The organic s...
Embodiment 3
[0040] Supercritical Fluid Extraction Method C: 2.5 kg of blood dried blood fine powder after crushing and sieving, was firstly extracted with non-polar ineffective components of blood dried blood by the same method as in the above-mentioned embodiment 1 and embodiment 2 to obtain 2.36 kg of extract , and then use the extraction residue as a raw material to carry out polar supercritical extraction with organic solvent methanol to remove polar ineffective components, and finally obtain 1.90 kg of an extraction residue of active components of dried blood.
