Abstract
The invention provides an antifoaming agent for food fermentation. The antifoaming agent is obtained by stirring an active ingredient which is a mixture of polyethylene glycol, polyoxyethylene polyoxypropylene glycerol and high-carbon alcohol and accessories comprising an active emulsifying agent and a dispersant, wherein the mass ratio of the polyethylene glycol, the polyoxyethylene polyoxypropylene glycerol to the high-carbon alcohol is (1-3):(1-3):(1-3); the active emulsifying agent is glycerol monostearate, fatty alcohol-polyoxyethylene ether or alkylphenol ethoxylate; the dispersant is hydrophobic silicon dioxide; the high-carbon alcohol is C7 to C9 alcohol.
Description
Technical field
The invention belongs to water treatment agent field, be specifically related to a kind of defoamer, relate in particular to a kind of defoamer for food fermentation field.
Background technology
At fermentation industries such as pharmacy fermentation, gourmet powder fermenting, long-chain biatomic acid fermentations, in fermentation production process, fermentation need to have a large amount of nutrition, therefore add many polymer substances such as sucrose, starch, the bacterial classification simultaneously using due to fermentation is aerobic bacterial classification, therefore, in fermentation production process, need under stirring state, carry out air blast, improve oxygen content in zymotic fluid, the oxygen needing when strain fermentation is provided; So certainly lead to a large amount of foams in aerobic bacterial classification fermentation production process, because a large amount of foams occurs, if do not carried out froth breaking, to cause the overflow of part zymotic fluid to be gone out, in order to reduce loss of material, the dischargeable capacity of raising equipment, all carries out defoaming treatment at one grade fermemtation tank and second order fermentation tank in industrial processes.
It is normal that sweat produces a small amount of foam, brings many unfavorable factors but rise to steep oneself-meeting, as the coefficient of fermentation tank reduces, oxygen transmission system reduces etc.When foam is too much, affect even more serious, can cause various impacts: 1. reduce production capacity, as various biofermentations (Beer Brewage, alcohol manufacture, the equipment such as various fermentation tank reactor cookers in each large antibiotic production pharmaceutically, in order to prevent the appearance of foam, the loss that prevents from overflowing, batch charging coefficient will be had a greatly reduced quality, and does not sometimes reach 30%.2. cause wastage of material: due to foam, can cause useful or valuable raw material to lose because overflowing, consequent waste is just self-evident.As the operation that oils of the weaving process of paper mill, sugar refinery full charge operation, textile mills, often because causing, foam overflows.3. extended reaction time: owing to including gas, liquid in chemical reaction product, foam can cause gas to be detained, and has extended reaction time, unnecessarily the power that consumed more.And for example wine fermentation is spoiled because foam existence makes overreact.If 4. affect the breathing bubble stabilizes of bacterium, not broken, along with the breathing of microorganism, in bubble, be full of carbon dioxide so, and can not exchange with oxygen in air again, so just affect the breathing of bacterium.5. cause microbiological contamination: cause and escape liquid because foam increases, so be stained with culture medium in blast pipe, just president bacterium.Along with time lengthening, miscellaneous bacteria can be grown into fermentation tank and be caused microbiological contamination.A large amount of foams are further seeped into shaft seal by tank deck, and the lubricating oil at shaft seal place can the effect of starting point froth breaking, and the foam falling from shaft seal often causes living contaminants.
Summary of the invention
The invention provides a kind of defoamer for food fermentation defoaming treatment, take the mixture of polyethylene glycol, polyoxyethylene oxypropylene glycerine and higher alcohols as froth breaking active component.
For achieving the above object, the present invention adopts following technical scheme:
A kind of food fermentation defoamer, take the mixture of polyethylene glycol, polyoxyethylene oxypropylene glycerine and higher alcohols as active component, is aided with emulsifying agent activating agent, dispersant, after stirring, emulsification, obtains.
In technical scheme of the present invention, polyethylene glycol, polyoxyethylene oxypropylene glycerine and higher alcohols (1 ~ 3) in mass ratio: (1 ~ 3): (1 ~ 3).
In technical scheme of the present invention, described emulsifying agent is the one in glyceryl monostearate, AEO or APES.
In technical scheme of the present invention, described dispersant is hydrophobic silica.
In technical scheme of the present invention, the alcohol that described higher alcohols are C7 ~ C9.
Higher alcohols are strong hydrophobic weakly water-wet linear molecules, are effective defoamer in aqueous systems.The present invention studies discovery, and the alcohol of C7 ~ C9 mixes with polyethylene glycol, polyoxyethylene oxypropylene glycerine, the froth breaking activity short deficiency of holding time can make up polyoxyethylene oxypropylene glycerine as defoamer time.And surface-active is strong, defoaming effectiveness is high.
The effect of emulsifying agent is to make active component to be dispersed into granule, is convenient to be dispersed in water, and improves infiltration and the diffusivity of defoamer, better plays froth breaking, presses down bubble effect and make defoamer be easy to infiltrate between foam, and come in the diffusion of foam surface rete.In the preferred technical scheme of the present invention, described emulsifying agent is the one in this dish-40, this dish-60, Tween-20, Tween-60, Tween-80.
The effect of dispersant is the surface tension reducing between defoamer suspension and processed liquid, makes defoamer spread in liquid surface with form of film.In the preferred technical scheme of the present invention, described surfactant is hydrophobic silica.
Based on technique scheme, defoamer provided by the invention divides composed of the following components by quality:
Active component 25 ~ 40
Emulsifying agent 8 ~ 12
Dispersant 1 ~ 3
Than prior art, the beneficial effect of defoamer provided by the invention:
(1) defoamer provided by the invention good dispersion in aqueous systems, antifoaming speed is fast, but the bubble time is long, presses down bubble effective;
(2) defoamer provided by the invention does not affect sweat conversion ratio, on generate product without impact.
