Description
Technical field
The present invention relates to a kind of disinfectant, specifically a kind of DBDMH disinfecting agent that is used for beer or beverage production device.
Background technology
C5H6Br2N2O2 is chemical products 1,3-two bromo-5, the abbreviation of 5-DMH.Since need microorganism is controlled in the beer fermentation process, thus need carry out sterilizing to the beer pipe-line equipment, otherwise can produce very large influence, the health that directly endangers the people to the production of beer.China's beer industry has had very perfect CIP operating system, and the control of microorganisms in the beer production has been played positive effect.Disinfectant in CIP operating system has two kinds of selections basically: (1) clorox class, (2) Peracetic acid class.Lacking of the comparison that clorox is used in present brewery, reason is that clorox needs very high concentration to use in the sterilization of beer pipe-line equipment, meeting etching apparatus pipeline to a great extent in the application process, and clorox also exists bigger defective aspect security performance.Therefore, brewery generally all uses Peracetic acid class disinfectant, and Peracetic acid belongs to bactericidal agent, and the good sterilization effect is arranged.But Peracetic acid has potential safety hazard in transportation in the storage process; The corrosivity of itself is strong, can produce very big corrosion to pipe-line equipment; Peracetic acid itself has very big irritating taste, contact skin meeting burned skin; These shortcomings make it in use produce very big problem.
Summary of the invention
The objective of the invention is to design the DBDMH disinfecting agent in a kind of beer or the beverage production device, so that production equipments such as beer or beverage provide a kind of safe reliable and effective disinfectant.
According to technical scheme provided by the invention, the prescription of DBDMH disinfecting agent is C5H6Br2N2O2 20-40%, cosolvent 0.1-5%, and stabilizing agent 20-50%, synergist 0.1-2%, effervescent agent 10-40%, unit is a mass percent.
Described cosolvent is an ammonium sulfate, ammonium carbonate, carbonic hydroammonium, the one or any two kinds mixing in the ammonium phosphate; Stabilizing agent is an anhydrous sodium sulfate; Synergist is a sodium alkyl sulfate, alkyl trimethyl ammonium halide, the one or any two kinds of mixing in the sodium carboxymethylcellulose; Effervescent agent is a citric acid, tartaric acid, sodium acid carbonate, the one or any two kinds of mixing in the sodium carbonate.
The production method of DBDMH disinfecting agent: at room temperature with at least a C5H6Br2N2O2 that is selected from surface compositions, cosolvent, synergist, stabilizing agent, effervescent agent is mixed in the powder stirrer, mixes.
C5H6Br2N2O2 is the novel second generation release property disinfectant of a class, and the good sterilization effect is arranged itself.Active bromine in the C5H6Br2N2O2 (effectively bromine) is the main component of killing microorganisms, and in the aqueous solution, C5H6Br2N2O2 can discharge the bromine cation, forms hypobromous acid and free active bromine.Hypobromous acid has strong oxidizing property, the biology enzyme oxidation Decomposition in the microbial body can be lost efficacy, and plays very strong bactericidal effect, the free bromine that discharges in the water can also with the nitrogen-containing compound generation amine bromide that reacts, still have bactericidal action.Remaining 5,5-DMH can be decomposed ammonification and carbon dioxide in the short period of time by light, oxygen, microorganism etc. under field conditions (factors), can be because of residual and contaminated environment, and can the toxigenicity material.And C5H6Br2N2O2 is solid disinfecting agent, so do not have the shortcoming of peroxyacetic acid disinfectant in transportation, storage, use.
Though C5H6Br2N2O2 has many advantages as above, because C5H6Br2N2O2 solubility in water is very low, dissolution velocity is slow, and has higher interfacial tension, thereby has influenced C5H6Br2N2O2 as the application of disinfection sanitizer in the sterilization of beer pipe-line equipment.CN02111332.7 discloses C5H6Br2N2O2 and solubilizer, synergist, disintegrant etc. composite, solves the problem of C5H6Br2N2O2 poorly water-soluble.But what the solubility of C5H6Br2N2O2 still compared in the described invention is little, and sterilizing ability also is difficult to adapt to the requirement of beer pipe-line equipment sterilization.Wherein related to solubilizer, disintegrant and some other auxiliary agent in addition, it is loaded down with trivial details that technology compares, and cost is also very high.CN10123142.8 is by adding solubilizer, synergist, stabilizing agent and water, made the aqua disinfectant of C5H6Br2N2O2, but the aqua disinfectant is in transportation, all can lack security in the storing process, and the aqua disinfectant is more far short of what is expected than solid disinfecting agent aspect disinfectant stable than solid disinfecting agent.The present invention is based on C5H6Br2N2O2, is equipped with cosolvent, synergist again, stabilizing agent, the composite instant granular type DBDMH disinfecting agent that forms can not produce safety problem in the transportation storing process, good stability, in use simple and convenient, and have good bactericidal effect.
C5H6Br2N2O2 is nitrogenous class material, so cosolvent is selected ammonium class salt, according to the principle of similar compatibility, ammonium class salt can well the dissolving of hydrotropy C5H6Br2N2O2 in water.Anhydrous sodium sulfate can absorb the moisture of trace, makes disinfectant stable.Produce carbon dioxide when effervescent agent can be dissolved in water, disinfectant can be stirred in dissolving fully.Synergist is the sterilizing ability in the sterilization of beer pipe-line equipment that is used for strengthening C5H6Br2N2O2.
The mensuration of effective bromine content is carried out according to indirect iodimetric titration in the DBDMH disinfecting agent, and its principle is that C5H6Br2N2O2 is oxidized to iodine with KI earlier, and then uses the sodium thiosulfate standard solution titration in acid solution.
DBDMH disinfecting agent also can carry out disinfection usefulness in air sterillization and the daily life except using in the sterilization of beer pipe-line equipment.Using method is identical with other common disinfectantses, and in general, the effective bromine content of air sterillization needs 300-500mg/L, and daily life effective bromine content of sterilizing needs 200-300mg/L.
The invention has the beneficial effects as follows:
(1) the invention provides the instant granular of C5H6Br2N2O2, dissolution velocity and solubility are improved greatly, under the room temperature, the solubility of C5H6Br2N2O2 in water can be increased to 10%-30%.Therefore, the present invention has at first solved the instant problem of C5H6Br2N2O2, and the application of sterilizing on the beer pipe-line equipment for DBDMH disinfecting agent provides condition.
(2) bactericidal effect of described DBDMH disinfecting agent is far superior to the result of use of such disinfectant in the market.Under the normal condition, need effective bromine 2000mg/L for killing of bacillus subtilis black variety gemma, effect just can be killed half an hour, and the DBDMH disinfecting agent of the embodiment of the invention 2 only needs 100mg/L just can kill bacillus subtilis black variety gemma effectively.
(3) described DBDMH disinfecting agent has also carried out synergy to surperficial sterilization effects.The present invention can be applied to the sterilization of beer pipe-line equipment in order to make DBDMH disinfecting agent, adds synergist the surface tension of disinfectant is reduced to below the 35dyne/cm, makes disinfectant can be good at the wetting surface that needs sterilization in the sprinkling process.
(4) DBDMH disinfecting agent of the present invention can be applied to the sterilization of beer pipe-line equipment fully.DBDMH disinfecting agent can be good at killing various aerobic bacterias, the anaerobic bacteria that produces in the beer fermentation process, guarantees the control of microorganisms in the beer production, and effect stability is effective.The DBDMH disinfecting agent sterilization process is simple, easy to use, reduced the cost of sterilization to a great extent, with Tsingtao beer four factories is example, scrubs 12 yeast tanks and 9 fermentation tanks equally, under the identical situation of effect, the cost of the disinfectant of Peracetic acid class is 2906 yuan, use DBDMH disinfecting agent, cost only needs 756 yuan, can reduce disinfection cost 70%.And disinfectant do not produce poisonous and harmful substance after using, and is the beer pipe-line equipment disinfectant of a kind of novelty, efficient, environmental protection.
