The selected compound emulsifiers moa-4, tx-4 and tx-10 of the preservative-free organosilicon defoamer disclosed by the invention are condensation compounds of fatty alcohol and ethylene oxide and polyoxyethylene octylphenol ether-series emulsifiers, and cannot be mildewed in case of being stored for a long time; the selected ASE-60 thickener is also an acrylic acid thickener, and also cannot be mildewed; a preservative and a bactericide do not need to be added in production; strain growth cannot be killed, suppressed and influenced in food fermentation, medicine fermentation and other systems related to strain culture; the increase of product yield is promoted.
Description
Technical field
The present invention relates to the silicone defoaming agent of a kind of food fermentation, medicine fermentation use, in particular a kind of not containing the silicone defoaming agent of anticorrisive agent.
Background technology
In many production processes, due to various different reason, material can produce a large amount of foam, causes production normally not carry out, and increases energy consumption, reduces production efficiency, even affects product quality.Such as when producing the medicine such as antibiotic and vitamin, utilize in the fermentation tank of microorganism and often can be full of foam, the cultivation of unfavorable thalline, difficulty is all brought to technical process such as the separation of thalline, concentrated, separation of products, finally cause separation of products and purification difficult, product yield and Quality Down.Adding defoamer is the effective ways effectively overcoming these difficulties.
Defoamer purposes and use are widely, indispensable a kind of auxiliary agent in production process at industrial department defoamers such as chemical industry, papermaking, coating, food, weaving, pharmacy, it is without the foam that can remove on production process technology medium liquid level, thus improve filter, washing, extraction, distillation, evaporation, dehydration, the technical process such as dry the effect such as separation, gasification, discharge opeing, reduce energy consumption, raise the efficiency, guarantee the capacity of all kinds of material splendid attire, container handling.
Medium difference, foaming reason, the service condition of various industrial process generation foam are different with requirement, and the defoamer kind of use is also different.Such as food industry requires harmless defoamer, and paper industry needs the defoamer of ability boiling high temperature and resistance to highly basic.Therefore the kind of defoamer is a lot.Itself be often have various active component and solvent formulated, conventional active component polysiloxane, acid amides, fatty alcohol, phosphate etc.
Silicon-containing surfactant is as the gang in organo-silicon compound, and just for each industrial circle from the sixties, but extensive and comprehensive fast development is from the eighties.As silicone defoaming agent, its application is also very extensive, is more and more subject to the attention of all trades and professions.
Silicone defoaming agent is a large class important in anti-foam product.Main production technology is dimethyl silicone polymer and silicon dioxide microparticle, at high temperature well-mixed silicone oil cream is as froth breaking, broken bubble main body, compound emulsifying agent made by Span and Tween class surfactant again, is equipped with the milky emulsion shape defoamer that can disperse very well in aqueous phase that suitable thickener obtains as stable, dispersant.
The emulsifying agent that prior art uses mostly is the product of aliphatic acid and oleic acid etc. for anhydrous sorbitol monostearate series and APEO anhydrous sorbitol glyceryl monooleate, the thickening stabilizing agent sodium carboxymethylcellulose used, after being mixed with the defoamer aqueous solution, storage, placement easily produce mould, corruption, therefore will proportionally add anticorrisive agent, bactericide in process of production.With the addition of anticorrisive agent, the silicone defoaming agent of bactericide relies on Spawn incubation to obtain the industrial occasions of product in food fermentation, medicine fermentation etc., wherein contained anticorrosion, bactericide can kill bacterial classification, product yield is impacted, especially to growth to the toxicity ratio more sensitive fermentation initial stage, affect larger.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of not containing the silicone defoaming agent of anticorrisive agent, help the yield improving product.
The present invention is achieved by the following technical solutions: silicone defoaming agent of the present invention, by weight, comprises following component: dimethyl silicone polymer 130 ~ 140 parts, aerosil 4 ~ 7 parts, compound emulsifying agent 100 ~ 120 parts, thickener 6 ~ 10 parts, deionized water 600 ~ 800 parts.
As one of preferred embodiment of the present invention, by weight, comprise following component: dimethyl silicone polymer 134.4 parts, aerosil 5.6 parts, compound emulsifying agent 110 parts, thickener 8 parts, deionized water 700 parts.
As one of preferred embodiment of the present invention, described compound emulsifying agent is counted by weight proportion, comprises moa-4, tx-4, tx-10=21:21:13.
As one of preferred embodiment of the present invention, described thickener is ASE-60.
Not containing a preparation method for the silicone defoaming agent of anticorrisive agent, comprise the following steps:
(1) dimethyl silicone polymer and aerosil are dropped into reactor, be heated to 230 DEG C, keep 4 hours;
(2) when being cooled to 45 DEG C, emulsifying agent moa-4, tx-4, tx-10 is added successively, emulsify at a high speed 20 minutes in the emulsifying kettle of band shear;
(3) ASE-60 is dropped into the aqueous solution that deionized water is configured to, slow stream adds the material that in step (2), emulsification is good, adds rear high-speed stirred 40 minutes again, through colloid mill grinding barrelling, and obtained finished product.
As one of preferred embodiment of the present invention, the solution ph in described step (3) adjusts to 8, temperature 45 C.
Dimethyl silicone polymer is food grade defoamer, safety non-toxic evil; Aerosil has porous, nonpoisonous and tasteless pollution-free, high temperature resistant, as the auxiliary agent of anti-settling, thickening, resist sagging.
ASE-60 is a kind of cross-linked type macromolecule emulsion thickener containing acidic-group, when with water latting drown and with in alkali and time, its emulsion particle expands very soon, and under these conditions, changes is clarified and very thickness by emulsion.
The present invention has the following advantages compared to existing technology: compound emulsifying agent moa-4, tx-4, tx-10 that the present invention selects are condensation product and the OPEO series emulsifying agent of fatty alcohol and oxirane, and long storage periods can not go mouldy; Selected ASE-60 thickener is also acrylic acid class thickener, also can not go mouldy.Do not need aborning to add anticorrisive agent, bactericide.At food fermentation, medicine ferments and other relate in the system of Spawn incubation, does not have kill, suppress and affect growth.Contribute to improving product yield.
