Membrane filter pressing circulation extraction separation integrated technique of the present invention, be that the discharging opening of material-compound tank is communicated with the charging aperture of diaphragm filter press by pump (as membrane pump etc.), the liquid outlet of diaphragm filter press is communicated with the import of charging aperture and the filtrate tank of material-compound tank respectively with three-way valve.When three-way valve switches to the material-compound tank position, the liquid outlet of diaphragm filter press is communicated with the charging aperture of material-compound tank, constitute membrane filter pressing circulation extraction system, slip in the material-compound tank is pumped to diaphragm filter press to carry out the pressing filtering liquid that membrane filter pressing comes out from diaphragm filter press and passes back into (medicated powder then is deposited on the filter cloth surface of each filter pressing chamber of diaphragm filter press equably) the material-compound tank, be re-used as and extract solvent and be pumped to diaphragm filter press and carry out membrane filter pressing and constantly circulate, thereby the membrane filter pressing circulation that realizes medical material is extracted; When three-way valve switches to the filtrate tank position, the liquid outlet of diaphragm filter press is communicated with the import of filtrate tank, constitute the membrane filter pressing solid-liquid separation system, after the membrane filter pressing circulation extraction of medical material finishes, to send into the filtrate tank storage from pressing filtering liquid and pressed liquor that diaphragm filter press comes out, thereby herbal extract is well separated with medicinal residues.
About extracting the problem of material, usually pulverizing medicinal materials is become coarse powder as extracting material, the soft medical material (as Radix Rehmanniae Preparata, Fructus Jujubae etc.) that difficulty is ground into coarse powder can add the water that 2-4 doubly measures and be ground into slip as extracting material with feed grinder or tissue mashing machine.
About the problem of charging sequence, when the medical material fibre-bearing more after a little while, can be in material-compound tank directly add medicated powder and extract solvent, under stirring condition, carry out the membrane filter pressing circulation and extract; When the medical material fibre rich, then should adopt the outer circulation method of feeding in raw material, to stop that medicated powder stops up in material-compound tank discharging opening and feeding pipe and phenomenon that the stock circulation is obstructed.The reinforced method of so-called outer circulation is will extract required whole solvents earlier first to add in the material-compound tank, three-way valve is switched to the material-compound tank position, solvent is pumped into diaphragm filter press, (can observe from the manhole of material-compound tank) when passing back into material-compound tank when observing pressing filtering liquid (this moment is actual to be solvent), under stirring condition, progressively drop into medicated powder again, the gained feed liquid is pumped to diaphragm filter press thereupon carries out the membrane filter pressing pressing filtering liquid and passes back in the material-compound tank and circulate, and medicated powder then is deposited on the filter cloth surface of each filter pressing chamber of diaphragm filter press equably.
About extracting the problem of temperature, when being solvent with water, extracting temperature can control at 50-90 ℃, according to polarized light microscopy method measurement result and in conjunction with bibliographical information, starch gelatinization temperature in the plant tissue mostly is 70-71 ℃, for fear of occurring because starch gelatinization blocks cell inclusion (mostly being effective ingredient) stripping or stops up phenomenons such as filter cloth, the medical material of rich in starch is carried out water when carrying, extract temperature and should control below 70 ℃, preferred 55-65 ℃.And when adopting organic solvent extraction, the boiling point height of looking organic solvent can not heat (namely at room temperature extracting) or suitably heating.
About the problem of extraction time and extraction time, can require according to the response rate of index components and economy requirement suitable adjustment extraction time and extraction time.For the extraction of general medicinal material coarse powder, but selective extraction 2 times extracted 30-40 minute for the 1st time, extracted 10-20 minute for the 2nd time; Higher for price of medicinal material, require the higher kind of the index components response rate, extraction time can suitably increase, as extracts 4 times, extracts the 2-4 time extraction 10-20 minute 40-60 minute the 1st time; Also last 1 time extracting solution can be carried out recycled as the solvent of extraction first of next group material.When serving as when extracting solvent with alcohol-water mixed solution, carry out membrane filter pressing and wash and squeeze medicinal residues thoroughly in the extraction back available water that finishes, after gained pressing filtering liquid and pressed liquor are measured pure content, can be used as the next group material and extract preparing solvent liquid and carry out recycled.Carry out membrane filter pressing when washing thoroughly at water, also can close two liquid valves that are in low level in four jiaos of liquid valves of diaphragm filter press, water is fully soaked overflow the top filtering layer, to strengthen washing effect.
Need to extract earlier volatile oil about part medical material in the compound preparation prescription, medicinal residues merge the problem of carrying out decocting with other medical material again, reach a few hours owing to extract the process of volatile oil with the water azeotropic, during the water soluble ingredient of medical material fully is soluble in the aqueous phase in the process of extracting volatile oil, so generally do not need medicinal residues and the merging of other medical material are carried out decocting, and save follow-up concentrated energy consumption simultaneously for the response rate that guarantees effective ingredient, can be after extracting volatile oil, the water of doubly measuring with 2-4 is heated to the 60-90 ℃ of saturating wash slag of membrane filter pressing, wash 1-2 time thoroughly, aqueous solution after the saturating washing liquid of gained and the distillation merges, as the extraction solvent of water first of other medical material.
About the problem of diaphragm filter press, filter cloth should be selected polypropylene multifilament filter cloth for use, and its Air permenbility selection principle is: less (as 3-10L/m with the appropriate to the occasion Air permenbility of selecting for use of organic solvent extraction
2.s) filter cloth is big (as 50-1200L/m with the appropriate to the occasion Air permenbility of selecting for use of water extraction
2.s) filter cloth.Membrane filter plate should select polypropylene etc. to meet the plastic material of medicinal requirements.The feed liquid pipeline should be selected the plastic conduit of 304 above rustless steels or non-PVC for use.
