The extraction device comprises a dissolution tank, a filter, a first spray drier, an alkaline dissolution tank, an adsorbent resin unit, a ceramic ultrafiltration membrane, a nanofiltration membrane and a second spray drier. The special extraction device for the blue-green pigment of the abalone shell can be used for continuously extracting effective components in the abalone shell, and is high automation degree and convenient to operate.
Description
Technical field
The utility model provides the extraction element of natural component in a kind of abalone shells, particularly relates to the extraction element of blue-green pigments, belongs to natural component extractive technique field.
Background technology
Abalone is the monoshell mollusk in ocean, only has demifacet shell, and shell heavily fortified point is thick, flat and wide, and shell surface irregularity has chocolate patch, and inner face presents the pearliness that green grass or young crops, green, red, blue isochrome are enhanced each other's beauty.European, before year, is used as abalone as a kind of fresh aquatic food edible, and reputation is made " the soft gold on dining table "; , in Qing Dynasty period, just there is what is called " full Bao is feted " in China in imperial palace.According to data introduction, when coastal various places high-ranking official goes on a pilgrimage at that time, mostly paying tribute dry abalone is present, one product government official pays tribute a Bao, and seven product government officials pay tribute seven Baos, by that analogy, the height hook of abalone and government official's grade, its this taste is enjoyed the value of " hat of seafood delights " as seen.The traditional Chinese medical science claims that abalone effect can be calming the liver, and antipyretic improving eyesight, quenches the thirst treating stranguria; Cure mainly the hot superinverse of liver, have a dizzy spell, hectic fever due to yin labor heat, blue or green the region between the heart and the diaphragm cataract or glaucoma, the diseases such as hypertension retinal hemorrhage.Bao shell is famous Chinese medicinal materials Sea-ear Shell, is again its squaw weed on ancient book, has the effect of improving eyesight, hence obtains one's name.Sea-ear Shell also has the effect of heat-clearing, suppressing hyperactive liver for calming endogenous wind, the disease such as carpopedal spasm that can treat feels dizzy and have a fever causes, tic.
At present for the processing of abalone shells be generally medicinal after grinding, utilize calcium component in shell manufacture Calcium of intensifiens or directly abandon.The same with the shell of other shell-fishes, the main component of Bao shell is calcium, amino acid, chitosan, the extexine of removing after dirt settling at Bao shell housing has blue-greenish colour material, it is tightly attached to the outer rib layer of shell, different sorts abalone color that this layer of material presents is different, what have is partially green, and what have is partially blue. this class material water soluble, and there is absorption effects.
Summary of the invention
The purpose of this utility model is: a kind of special purpose device that can extract blue-green pigments of abalone shell is provided, and technical scheme is as follows:
A Special extraction device for blue-green pigments of abalone shell, includes the dissolving vessel, strainer, the first spray-dryer, alkali dissolution tank, polymeric adsorbent unit, ceramic super-filtering film, nanofiltration membrane, the second spray-dryer that connect successively.
Described strainer is sand-bed filter.
What in described polymeric adsorbent unit, fill is D201 macroporous strong basic negative resin.
The mean pore size of described ceramic super-filtering film is 10 nm.
The molecular weight cut-off of described nanofiltration membrane is 300 Da.
beneficial effect
The Special extraction device of the blue-green pigments of abalone shell that the utility model provides can continous way effective constituent in abalone shells is extracted, level of automation is high, easy to operate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Special extraction device of blue-green pigments of abalone shell.
Wherein, 1, dissolving vessel; 2, strainer; 3, the first spray-dryer; 4, alkali dissolution tank; 5, polymeric adsorbent unit; 6, ceramic super-filtering film; 7, nanofiltration membrane; 8, the second spray-dryer.
Embodiment
Embodiment 1
As shown in Figure 1, a Special extraction device for blue-green pigments of abalone shell, includes the dissolving vessel 1, strainer 2, the first spray-dryer 3, alkali dissolution tank 4, polymeric adsorbent unit 5, ceramic super-filtering film 6, nanofiltration membrane 7, the second spray-dryer 8 that connect successively.Described strainer 2 is sand-bed filters, and what in described polymeric adsorbent unit 5, fill is D201 macroporous strong basic negative resin, and the mean pore size of described ceramic super-filtering film 6 is 10 nm, and the molecular weight cut-off of described nanofiltration membrane 7 is 300 Da.
According to concrete leaching process, this device is described further below.
First, abalone shells is cleaned, dries, pulverizes, is ground to below 400 orders, then put it in dissolving vessel, add 5% acetic acid of 10 times of weight, be heated to 30 ℃, keep 24h; Then use strainer elimination insolubles, filtrate is delivered to the first spray-dryer to be dried, the powder obtaining is put in alkali dissolution tank, add again the NaOH solution of 1% (w/w) of 10 times of powder weight, soak 12h, then supernatant liquor is sent into and in polymeric adsorbent unit, carried out adsorption-edulcoration, feed liquid after removal of impurities is sent in ceramic super-filtering film and is filtered, filter pressure is 0.2 MPa, then filtrate is concentrated by nanofiltration membrane, when being concentrated into half volume, concentrated solution is sprayed dry with the second spray-dryer,, obtain blue-greenish colour powder.
Preparation massfraction is the methanol solution of 0.01% pigment, and take methyl alcohol as contrast, on ultraviolet-visible spectrophotometer, in wavelength 200～800nm scanning, the maximum characteristic absorption wavelength of pigment is 612nm, consistent with bibliographical information.
The abalone shells of every 1 kg, after extracting, generally can obtain 3-4 mg pigment powder.
