CS197058B1 - Liquid cleaning and desinfection means - Google Patents

Description

BACKGROUND OF THE INVENTION The present invention relates to a liquid cleaning and disinfectant for the primary production of milk and a dairy. In the Czech Republic and abroad, a wide range of cleaning and disinfecting agents are used to remove milk residues such as proteins, milk fat, minerals, various mechanical impurities and significant contamination with pathogenic, conditionally pathogenic and accompanying microorganisms. Acid, alkaline or neutral compositions with a high-performance disinfectant such as chlorine, iodine and other substances are used.

If powder formulations are used for cleaning and disinfection, they must first be completely dissolved, since only after they have been dissolved, the cleaning and disinfecting components are fully effective. However, in many cases, due diligence does not take proper care to reduce the efficiency of sanitation, in addition, some formulations contain mechanical impurities or poorly soluble components, which may create additional problems such as clogging of cleaning nozzles or spray heads, hard-to-clean places milking or cooling equipment and the like.

These drawbacks are fully eliminated by a liquid concentrated alkaline preparation with active chlorine, a surfactant and a dispersing or stabilizing component. This

197 058, for example, when cleaning and disinfecting a milk cooler type ZD 6 - 014 with a volume of 5,000 liters of chilled milk and equipped with an automatically controlled cleaning and disinfection process, it enables to achieve microbial purity according to the Czechoslovak state standard and conditions . In numerical terms, this means that there are less than 500 microorganisms per 100 cm of cleaned area of the cooling device and coliform microorganisms are absent.

Similar results with the same preparation were achieved in practice in cleaning and disinfecting milking equipment and milking parlors of domestic and foreign production, as well as tanks for transporting milk from primary production to dairies, cooling tanks and milk cooling lines, etc.

The advantage of the proposed composition is, besides its high cleaning and decontamination efficiency, as well as its clarity, since all active ingredients are dissolved, the absence of mechanical or other impurities, storage stability, a balanced ratio of cleaning, disinfecting, dispersing and surfactants in concentrated state.

Another advantage is the easy and accurate dosing by measuring the appropriate volume of the liquid concentrate for a particular type of device, thereby avoiding unnecessary losses in overdose or, conversely, a reduction in efficiency at low dosages. During use, it is necessary to observe generally valid regulations of work safety and hygienic principles.

Example 1

For the efficient cleaning and disinfection of raw milk cooling tanks used in milk production, a detergent according to the invention was prepared by dissolving 64.8% of water by 10% sodium hydroxide, 20% sodium hypochlorite, 5% sodium pyrophosphate and 0.2% of a polyglycoletheramine fatty acid chemical composition wetting agent. This product has been used in sanitizing tanks; Packo RM / IB with a capacity of 5,000 l and ZD 6-014 of the same size. Alkon ZS (1%) was used as a comparative cleaning and disinfecting agent. The results of the tests and their results (achieved degree of microbial purity of cooling tanks) are given in Table 1. As can be seen from the table, the results obtained are very good. The foaming of the product was satisfactory, adequate.

The following applies to the continued use of the proposed preparation;

1 / high efficiency at half concentration (compared to Alkon ZS), resulting in cost savings (product is very cheap),

2 / easy and accurate dosing, ie maintaining the required concentration,

3 / easy handling and cleanliness a

4 / satisfactory suppressed foaming

Example 2

A product was prepared containing 62.8% water, dissolved in 10% potassium hydroxide, sodium hypochlorite 20% solution in 20% potassium pyrophosphate in 5% and 0.2 fr of polyglycol etheramine fatty acid. The product was used under the same conditions as in Example 1 with virtually the same results.

Example 3

A product containing 62.9 fr of water, 10 fr of sodium hydroxide, 20 fr of a 20% sodium hypochlorite solution, 5 fr of sodium pyrophosphate and 0.2 fr of a wetting agent (polypropylene glycol / alkylene oxide) was prepared and tested under the same conditions as in Example 1. Under operating conditions, the product has been shown to have an extremely high cleaning performance, but its increased foaming was somewhat disruptive, and an increased amount of opaque bath was required to remove the foam.

Claims (3)

SUBJECT OF THE INVENTION Liquid detergent and disinfectant comprising sodium or potassium hydroxide in a concentration of 5 to 30 fr and sodium hypochlorite or potassium or isocyanuric acid derivatives containing chlorine in an amount of 1 to 10 fr, further comprising a stabilizing additive, eg sodium or potassium pyrophosphate in an amount of 2 to 25 fr, characterized in that it contains the active surfactant in an amount of 0.1 to 0.8 fr by weight of the chemical composition of the fatty acid amine polyglycol ether. 2. The invention as claimed in claim 1, wherein the surfactant comprises an anionic surfactant selected from sodium or potassium alkylbenzene sulphonate, sodium or potassium alkylpolyglycol ether sulphate in an amount of 0.2 to 1% by weight. 3. The process of claim 1 wherein the surfactant comprises sodium alpha-olefin sulfonate, sodium sulfosuccinate, or alkyl polyglycol dervitate, produced by ethyleoxidation of a fatty component containing a free OH group in an amount of 0.1 to 1% by weight.
