Description
Technical field:
The utility model belongs to natural colouring matter filtration purification and uses the technique with the apparatus field, relates in particular to a kind of molecular film filtering tank that improves the natural colouring matter quality that is beneficial to
Background technology:
Pigment by sources can be divided into natural and artificial coloring's two big classes.What the artificial chemical synthesis pigment of discovered in recent years had exists carcinogenic and mutagenesis, payes attention to so natural colouring matter is subjected to people day by day.Edible natural pigment color and luster nature, of a great variety, wherein a lot of main components are the proper constituents in the food, many edible natural pigments also have pharmacological action and health cares such as very outstanding treatment, prevention to the multiple disease of human body.Safety, color and luster are bright-coloured naturally, most not extensively developed rapidly by the restriction of additive and the scope of application owing to edible natural pigment has.The state that China also is in synthetic dyestuff and natural colouring matter at present and deposits and develop simultaneously.Because the safety issue of synthetic dyestuff, the degree that many synthetic dyestuffs allow in various countries to use is limited greatly, especially at food, medicine and cosmetic industry, so the extraction of natural colouring matter and application are the main directions of present and future development.Extraction, the purifying process of natural colouring matter are varied.Method has flooding, organic solvent extraction, alkali extraction, supercritical fluid extraction, microwave and ultrasonic wave processing, resin adsorption separation and purification, enzymatic treatment and membrane technology etc.In natural food colour extraction and subtractive process, adopt various new and high technologies can promote the development of natural food colour industry greatly.
Flooding, flooding are to extract the effective means of water colo(u)r to adopt hot water, sour water, buck lixiviate mostly.Wherein alkaline extraction mainly is to have used the influence of alkali to multiple biological substance in the flooding.For example.It is that the NaOH aqueous solution with 15%-40% is handled capsicum oleoresin that the alkali of capsicum red pigment extracts, and makes the fat constituent generation saponification in the capsicum red pigment, thereby discharges capsicum red pigment is free, and separation and purification can obtain product again.
The organic solvent extraction method, for water-soluble relatively poor, even water-fast fat-soluble pigment, adopt the organic solvent lixiviate.Solvent extraction method is a kind of method of generally using always of extracting pigment at present from animals and plants.Characteristics such as the organic solvent that generally uses in the production is ethanol, and it is nontoxic, safe, easy to be recycled that ethanol has.The pure lixiviate of main employing, acid alcohol lixiviate.From capsicum, extract capsorubin and be chilli worn into to be immersed in the organic solvents such as acetone, ethanol, chloroform, trichloroethanes behind the powder and carry out.Extract capsorubin with solvent method, because material composition complexity, the existing poor selectivity of the organic solvent of Shi Yonging, make the products obtained therefrom purity difference and peculiar smell is arranged, the further deodorizing and refining of product medicinal extract can must be used, but because smell substance and pigment composition character are approaching, with general separation or decomposition method, complicated operation and be difficult to obtain highly purified capsorubin.Comparatively speaking, organic solvent extraction method extractant is cheap, and equipment is simple, and operating procedure is simple.
Again just like the supercritical carbon dioxide extraction method.The intensified by ultrasonic wave extraction method, enzyme engineering technology extraction method etc., but it is very high to the production equipment input, equipment precision prescribed height, and control program is very complicated, has various defectives.So, flooding and organic solvent extraction method be the main extracting mode of present natural colouring matter, and flooding and the organically combination of organic solvent extraction method have more increased the operability that natural colouring matter extracts.
Although that natural food colour has is safe, the tone nature, have both advantages such as nutrition and pharmacological action, but its scope of application is still limited at present, trace it to its cause, the most less stable of natural colouring matter, in processing and process such as circulation, be subject to the influence of extraneous factor and in various degree bad change takes place, also there is poor, the difficult color matching of dying property in natural colouring matter itself in addition, and problems such as peculiar smell, foreign odor.And, especially need to be eager to solve as, the problem in the natural colouring matter filter, be example with the capsicum red pigment, with raw material of hot pepper extrude be graininess after, in again feed particulate material being dropped into jar, obtain leaching liquor after adding solvent naphtha, leaching liquor is through the preliminary impurity screening of filter tank, or deodorization.So the filtration of the first step is for the filtration of down-stream, purify, separate, operation such as centrifugal has crucial effects, the quality of the natural colouring matter of the follow-up finished product of direct relation.Present filtering tank, feed tube enter leaching liquor to tank body, and plugging together in the tank body fixedly has some gauzes, gauze be filled into the impurity in the leaching liquor and drop on jar at the bottom of discharge along scum pipe.But the gauze filter effect is bad, and withstand voltage form is poor, and mostly is plate and frame mechanism, and gauze is many perpendicular to flow direction, the working fluid that adopts all vertically sees through gauze, and with the full dose filter type that impurity in the liquid is held back, this mode causes problems such as the service life of gauze is little.For solving this technical problem, need appearance a kind of simple in structure, easy to use, good filtration effect, a kind of molecular film filtering tank that improves the natural colouring matter quality that is beneficial to of long service life.
Summary of the invention:
