CN200510018643.X reported a process for extracting Saponin Powder from turmeric. After cleaning the turmeric, crush it and pass it through a 60-80 mesh sieve, remove the sand and gravel in the mixture through a sand remover, then pass the turmeric mixture into the separation device to separate most of the fiber starch, and dehydrate the remaining saponin mixture After concentration, add a small amount of sulfuric acid for acid hydrolysis reaction to obtain 10% saponin hydrolyzate and 1.5 times the mass of gasoline, mix them, heat and extract for 9 hours to obtain saponin gasoline mixture and fiber waste residue, and centrifuge the saponin and gasoline mixture to deoil A saponin product is obtained. The separation technique of the present invention is traditional separation equipment, namely adopts 7.5 kilowatts, 7 separators of 25 cubic meters/per hour specification are connected in series, but can separate incompletely when being used for the separation of turmeric mixture, causes saponin mixture to still have For certain starch and fiber, high acid is used for acid hydrolysis; the separated starch mixture also contains a certain amount of saponin, and the yield rate of Saponin Powder per ton of turmeric is not high; and the original separator separation nozzle has a smaller aperture of 0.6~ 0.8mm, so that the flow of the turmeric mixture in the separation tube is small and the production power is low. Therefore, the present invention can also transform the aperture of the separating nozzle of the separator into 1-6 millimeters, and adopt 12 separators to be connected in series, and after the acid hydrolysis of the separated saponin mixture, 25%-50% high-concentration saponin hydrolyzate can be obtained, During extraction, the mass ratio of saponin hydrolyzate to gasoline is between 5:6 and 2:3, and the saponin-gasoline mixture is obtained by heating and extracting for 3 to 5 hours. Using this new process, only 60 to 80 tons of saponin are needed per ton of saponin Water, and water can be recycled to avoid pollution problems.
Report two,
A process method utilizing turmeric to cleanly produce saponin is realized by the following process steps:
(1) Raw material pretreatment: wash turmeric, crush it with a crusher, and grind it into a slurry with a mill after crushing, so that the particles in the slurry reach 30 mesh, and the mass percentage concentration is 30%;
(2) Extraction of saponin pulp: use a variable frequency differential speed horizontal screw discharge sedimentation centrifuge to separate, separate out starch, and obtain saponin pulp;
(3) Place the saponin pulp at room temperature and ferment naturally for 36 hours;
(4) Acid hydrolysis: put the fermented saponin pulp right into the hydrolysis container, and accomplish acid hydrolysis with sulfuric acid, and also the pressure is managed at 0.2 MPa to acquire the hydrolyzed saponin pulp;
( 5 ), acid cleaning and water elimination: acid cleaning as well as water removal are carried out on the filter press to obtain filter deposit; at the same time, sewage is generated;
( 6) Drying: Place the filter deposit right into a vacuum cleaner clothes dryer with vapor in the interlayer for drying out, and also manage the water content of the filter deposit at 3-5%;.
( 7) Put the dried out filter deposit right into the extraction tank, add No. 120 fuel, the mass proportion of saponin slurry to gas is 5:6, warmth to 90 levels Celsius, and also the removal time is 2 hours to get the Saponin Powder fuel mixture; at the same time, Separation of insoluble fibers;.
( 8) Concentrate and crystallize the saponin-gasoline mix to obtain the ended up product;.
( 9) Release the sewage created in step (5) right into the neutralization storage tank as well as respond with lime, then go into the electrolysis device for electrolysis, after that go into the hydrolysis anaerobic tank for anaerobic organic treatment, and afterwards go into the three series-used pusher The circulation type oygenation container is made use of for biological reaction therapy, and finally enters the sedimentation storage tank for sedimentation. The cured water is entirely as much as the standard, as well as is reused for step (1) and step (5 ).
