Description
Technical field
The utility model relates to zymin extraction equipment, particularly a kind of zymin ultra-fine filter circulation cleaning device.
Background technology
The lower-molecular substance that contains many inorganic salt, sugar and amino acid and so on the enzyme solution extracting in microbe, they all have a great impact the color of zymin, smell, water absorbability and anti-caking etc.Conventionally the concentrating under reduced pressure adopting, saltout and the method such as organic solvent deposit, though these components can be got rid of, its process is more complicated, and goods purity and the rate of recovery are all lower.Closely during the last ten years, in the production of liquid enzyme formulation, successfully adopt membrane separation technique to dewater concentrated, obtained good benefit.Using membrane separating technology concentrates and refines enzyme, and operating process is simple, has reduced the chance of living contaminants and enzyme deactivation, has improved the rate of recovery of enzyme and has improved the quality of product.The molecular mass of conventional zymin is between 10000Da～100000Da, this scope is just within the scope of ultra-filtration technique application, adopt ultra-filtration technique that crude enzyme liquid is processed, lower-molecular substance can be removed through fenestra with salt together with water, and enzyme is concentrated and refine.The propositions such as nineteen sixty-five Blatt are carried out the concentrated of microorganism by membrane separation technique, and test.Nineteen sixty-eight Wang etc. successfully uses again ultra-filtration technique to concentrate several zymins.The U.S., France, Germany and the state such as Japanese have carried out industrial scale and have applied afterwards, with ultra-filtration membrane device, enzyme is concentrated, refining, be used for producing proteolytic enzyme, Polyglucosidase, rennin, polygalacturonase, trypsinase, notatin, heparin and beta-galactosidase enzymes etc., obtain good benefit.China, since phase early 1980s, has also carried out working in large quantities in this field, to utilizing the plurality of enzymes preparations such as various membrane separation concentration saccharifying enzyme, amylase, proteolytic enzyme to be studied, and for the production of, obtain obvious economic benefit.
Ultra-fine filter becomes indispensable visual plant in zymin leaching process, but the core component-ultra-filtration membrane of ultra-fine filter is in the work of holding back, after normal use for some time, some trapped substances can be attached to film surface, some fenestras will be trapped thing obstruction and the permeability rate of film is decreased like this, reduce the permeable amount of film and the pressure of increasing membranous wall, increase ultrafiltration system pressure, cause system enzyme liquid temp to raise, production efficiency and quality product have not only been reduced, and can greatly shorten work-ing life of ultra-filtration membrane, and in existing industrialization production process of enzyme preparation, in order to reduce zymin comprehensive cost, conventionally can improve the cycles of concentration in zymin leaching process, carry out iterative cycles concentrated, cycles of concentration reaches 20-30 doubly not etc., film pollutes even more serious in this case.So, for improve production efficiency and product quality; In order to extend ultra-filtration membrane work-ing life; In order to maintain the stable of film permeability rate, regularly to clean ultra-fine filter.
Existing zymin ultra-fine filter does not have independently cleaning system when cleaning, in ultra-fine filter import, pass into clear water, sewage directly drains into trench from sewage draining exit, has not only wasted a large amount of clean water sources, and cause serious environmental pollution, strengthen enterprise's sewage disposal load simultaneously, increased product monomial cost accounting, and, if ultra-filtration membrane stops up serious, need to carry out matting, can greatly waste clean-out system so, above-mentioned situation can be more serious.In sum, no matter carrying out physical cleaning still carries out matting, existing zymin ultrafiltration system all can not well clean and safeguard ultra-fine filter.
