Description
Technical field
The invention belongs to film concentration technique field, be specifically related to a kind of embrane method and move the continuous gelatin enrichment facility of embrane method for preparing gelatin on filtering and impurity removing that concentration technique is applied in gelatin, the concentration technology continuously.
Background technology
Gelatin is the product that the collagen in the tissues such as the skin, bone of animal obtains through partial hydrolysis; It is a kind of important native protein high polymer; Contain the nearly all essential amino acid except that tryptophan, it has purposes widely at food, medicine, photograph and industrial department.In traditional manufacturing of gelatin technology, needs elder generation is concentrated to 3%～5% gelatin solution more than 25%, carries out the freezing glue of cutting again.This process is to adopt triple effect evaporator evaporation and concentration gelatin solution traditionally, and its " one imitates " temperature is up to 8O ℃, and gelatin is a heat-sensitive substance, and gelatin solution causes the gelatin thermal denaturation easily at this overstand.Destroy the gelatin product quality.And one ton of water of average every evaporation (removal) needs to use O.3～0.4 ton steam, consumes mass energy, and the steam of evaporation process consumption accounts for about 40% of the required steam of manufacturing of gelatin overall process greatly.Thereby gelatin technologist strive for improvement technology and equipment, prevent and reduce destruction the gelatin performance.
Traditional manufacturing of gelatin technological process: in raw material (skin, bone), degreasing, pickling, liming, the washing and extracting, filtration, diatomite filtration, ion-exchange, evaporation and concentration, sterilization, drying and crushing, packing.
Membrane separation technique is the high efficient separation technology that develops rapidly in recent decades.Unique advantage such as the selectivity that membrane separation technique had, isothermal, no phase transformation, energy-conservation, no chemical reaction, cost are low particularly can optionally be separated the big molecule of gelatin with inorganic salts, gelatin is not had absorption, no degradation.Owing to the fracture of key in various degree takes place, so gelatin is made up of the protein of different molecular size and distribution when the preparation gelatin.Little molecule in the embrane method concentration technique ability selective removal gelatin is like salinity, low-molecular-weight amino acid.These little molecules are present in the gelatin, and the ash content that can increase gelatin reduces the power of freezing of gelatin; After part is removed small-molecule substance, can obviously improve Gel Strength of Gelatin and reduce ash content, improve the quality of products.
The principle of circulation film concentrator operational mode is that the gelatin trapped fluid is back to again in the Raw material pail and gets into circulation again and concentrate; Along with the increase The decline of membrane flux of feed concentration is serious; And this moment, gelatin was longer relatively running time; Its heated time is also longer relatively, and some big molecules can thermal degradation become little molecule, and Gel Strength of Gelatin will be lost like this.Bacterium is the same with gelatin when film concentrates is trapped, and in circulation type membrane equipment, along with time lengthening, microorganism will increase severely with the geometric progression procreation, and content of microorganisms increases greatly in the gelatin after concentrating thereby make.These bacteriums can cause some gelatin that enzyme digestion reaction can take place on the film surface viscosity drop of gelatin is raise at the surperficial extracellular proteinase (molecular weight is probably at 20000-40000Da) of film.In addition, in circulating concentrator, mostly membrane module is parallel form, needs powerful pump like this, and energy consumption is high.
Summary of the invention
In order to solve problems such as the energy consumption that has now in the manufacturing of gelatin technology is high, product freezes power and viscosity is low, ash content is big, the present invention provides a kind of continuous gelatin enrichment facility of embrane method that is applied in gelatin filtration, the concentration technology.
Concrete technical solution is following:
The continuous gelatin enrichment facility of a kind of embrane method comprises rolled membrane module 6, and the outlet of said rolled membrane module 6 is being communicated with first interface of four-way connection, and second interface of four-way connection is being connected virgin rubber jar 1 and dense glue jar 8 respectively with the 3rd interface; The import of rolled membrane module 6 is being communicated with the outlet of circulating pump 5; Connecting successively between the import of virgin rubber jar 1 and circulating pump 5 suction pump 2 and filter 4; First stop valve 3 of connecting on the pipeline between suction pump 2 and the filter 4; Second stop valve 10 of connecting on the pipeline between the outlet of virgin rubber jar 1 and rolled membrane module 6; The 3rd stop valve 9 of connecting on the pipeline between the outlet of rolled membrane module 6 and the dense glue jar 8; Parallelly connected the 4th stop valve 11 between the 4th interface of the import of circulating pump 5 and four-way connection; One side of rolled membrane module 6 is provided with discharging opening, and the discharging opening place is provided with first butterfly valve 7.
Said rolled membrane module 6 is made up of the rolling milipore filter tandem more than two, and the molecular cut off of milipore filter is 5000-10000MW.
The present invention concentrates running technology with continuous gelatin and is applied in the gelatin concentration technology.
The present invention compares the advantage with following interior aspect with present embrane method circulation concentrator.
1, the film separation process be with pressure as motive force, thereby separator is simple, processing ease is prone to automatic control and maintenance.
2, the film separation process can be carried out at normal temperatures, be specially adapted to this heat-sensitive substance of gelatin separation, concentrate, purifying, and have advantage such as energy-conservation, non-environmental-pollution.Use identical film, under identical cocnentration factor, the operational mode that continuous concentration operational mode power consumption concentrates than circulating is to lower.
3, adopt membrane separation process, can be with a large amount of impurity (salt, small molecular protein) filtering, the ash content clearance is high.Use identical film, under identical cocnentration factor, the continuous concentration operational mode is higher to the clearance of ash content than the operational mode that circulation concentrates, gelatin freeze power and viscosity height.
4, adopt membrane separation process, can the small molecular protein filtering have been reduced the yield of low value gelatin, improve the quality of products.
