CN103074180A - Acidic cleaner for food contact surface of liquid milk equipment - Google Patents

Abstract

The invention relates to an equipment cleaner in the dairy industry. The cleaner is mainly used for cleaning the inner surface of liquid milk equipment, and comprises the following components in percentage by mass: 40-65% of nitric acid, 1-15% of phosphoric acid, 0.1-1% of acidic complexing agent and 30-55% of water, wherein the total acidity of acid liquor of the acidic cleaner is 45-70% of the total concentration of the mass percentage of the nitric acid; the acidic complexing agent comprises the following components in percentage by mass: 1-15% of phosphoric acid, 0.05-11% of EDTA (Ethylene Diamine Tetraacetic Acid), 0.01-0.5% of DTPA (Diethylene Triamine Pentaacetic Acid) and 74-95% of water. The cleaner has little foam, and is easy to flush, so that the cleaning effect is improved; the cleaner is suitable for water qualities with different hardness to prevent scale from depositing; as the content of a compound is high, a suspension effect is provided for insoluble dirt, and strong redeposition resistance is achieved; and the cleaner can dissolve organic substances in the production residual dirt, such as butter oil, protein and galalith.

Description

A kind of liquid milk equipment food contact surface acidic cleaner

Technical field

The present invention relates to a kind of Dairy Industry device cleaning agent, be mainly used in the cleaning of the internal surface of liquid milk equipment.

Background technology

Traditional Dairy Industry equipment washing is used industrial strong acid, although also played the effect of cleaning equipment, exists significantly not enough in the following aspects.For human body, the power of burning of industrial strong acid is very strong, and danger close in the use is also inconvenient.Industrial strong acid is very strong to the corrodibility of equipment simultaneously, has greatly increased consumption and the expense of spare part, especially to rubber seal, often carbon black can occur after the pickling, damages relatively serious.Aspect environmental protection, a large amount of sour blowdowns.Can cause bad impact to environment.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of liquid milk equipment food contact surface acidic cleaner, the problem of cleaning to solve Dairy Industry liquid milk equipment food contact surface.

For solving the technical problem that exists, the technical solution used in the present invention is: a kind of liquid milk equipment food contact surface acidic cleaner, and it forms component and each constituent mass per-cent is,

Nitric acid, 40-65%;

Phosphoric acid, 1-15%;

The acid complexing agent, 0.1-1%;

Water, 30-55%;

Each constituent mass per-cent summation is 100%, and wherein, the mass percent total concn that the acid solution total acidity of acidic cleaner is amounted to into nitric acid should be 45-70%; Acid complexing agent moiety and mass percent be,

Phosphoric acid, 1-15%;

EDTA，0.05-11％；

DTPA，0.01-0.5％；

Water, 74-95%;

Each constituent mass per-cent summation is 100%.

Beneficial effect

The invention provides the acidic cleaner of the Dairy Industry liquid milk equipment food contact surface of highly effective and safe.The present invention also has the following advantages except having avoided above deficiency: foam is few, and easily flushing improves clenaing effect; Be suitable for the water quality of different hardness, prevent incrusted deposit; Because compound content is high, for insoluble dirt provides suspension effect, so have very strong antiredeposition ability; Can dissolving produce organic substance in the residual dirt, such as dairy fats, protein and mammary calculus.

Acidic cleaner belongs to environment-friendly type polyprotonic acid/composite clean-out system of acid complexing agent, can effectively remove on stainless steel tube, rubber hose and the glass piping or the residual mineral substance in inner surface, and such as the calcium in the hard water and magnesium, the stone that prevents from suckling forms.

Embodiment

Below in conjunction with specific embodiment the present invention is specifically described.

Compositional type Dairy Industry equipment acid cleaner production process

1. nitric acid, phosphoric acid are joined in the special reaction vessel, stir, detect mixed solution mass percent concentration (in nitric acid), calculate water consumption according to aimed quality percentage concentration (in nitric acid);

2. water is joined in the special reaction vessel, stir;

3. sour complexing agent is joined in the special reaction vessel, stir;

4. detect acid solution total acidity (mass percent concentration);

5. total acidity is qualified, and acid solution is packed by customer requirement.

The nitric acid mass percent concentration that uses in the production process is 30-98%, the phosphoric acid quality percentage concentration is 75-90%, the aimed quality percentage concentration is 15-45%, and acid solution per ton adds 0.1-1% acid complexing agent, and finished product feed liquid mass percent concentration (take nitric acid) is 45-70%.
