The isolation integral technology is extracted in membrane filter pressing circulation 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 (such as membrane pump etc.), the liquid outlet of diaphragm filter press is communicated with respectively the import of charging aperture and the filtrate tank of material-compound tank 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, consist of membrane filter pressing circulation extraction system, slip in the material-compound tank is pumped to diaphragm filter press to carry out membrane filter pressing 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 from diaphragm filter press pressing filtering liquid out, 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, consist of the membrane filter pressing solid-liquid separation system, after the membrane filter pressing circulation extraction of medical material is complete, to send into the filtrate tank storage from diaphragm filter press pressing filtering liquid and pressed liquor 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 (such 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 is less, can in material-compound tank, directly adds 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 first first required whole solvents 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 again medicated powder, 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, during take water as solvent, extract temperature and can be controlled 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 the phenomenons such as filter cloth, when the medical material of rich in starch is carried out water extraction, extract temperature and should be controlled at below 70 ℃, preferred 55-65 ℃.And when adopting organic solvent extraction, can not heat (namely at room temperature extracting) or suitably heating depending on the boiling point height of organic solvent.
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 first extraction solvent of next group material.When take alcohol-water mixed solution as the extraction solvent, carry out membrane filter pressing in the complete rear available water of extraction and thoroughly wash and squeeze medicinal residues, after gained pressing filtering liquid and pressed liquor were measured pure content, the preparation liquid that can be used as next group material extraction solvent carried out recycled.Carry out membrane filter pressing when thoroughly washing 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 extract first 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 extracting 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, therefore generally do not need medicinal residues and the merging of other medical material are carried out decocting, and save simultaneously follow-up concentrated energy consumption 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, thoroughly wash 1-2 time, aqueous solution after the saturating washing liquid of gained and the distillation merges, as the first water extraction solvent of other medical material.
About the problem of diaphragm filter press, filter cloth should be selected polypropylene multifilament filter cloth, and its Air permenbility selection principle is: less (such as 3-10L/m with the appropriate to the occasion Air permenbility of selecting of organic solvent extraction
2.s) filter cloth is large (such as 50-1200L/m with the appropriate to the occasion Air permenbility of selecting 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.
