TECHNICAL FIELD OF THE INVENTION
The invention relates to a method and a composition of a cleaning tablet or a cleaning powder for the removal of milk residues. The cleaning tablet or cleaning powder is first dissolved in water or substantially in water for use. Furthermore, the invention relates to a method for removing milk residues.
BACKGROUND OF THE INVENTION
Milk residues are often produced when milk is heated. The cleaning of apparatus parts with milk residues is a widely known problem, especially with regard to coffee machines. Especially for the mixing of milk in the coffee is preferred by the consumer hot milk. However, milk residues on heavily heated surfaces and / or dried milk residues are particularly difficult to remove.
In the disclosure EP 2 050 811, for example, a set of cleaning bags is offered which contains a basic cleaning agent in some bags and an acidic cleaning agent in other bags. The cleaning method proposed therein is based on alternately alkaline and acid treatment.
Good and fast-acting detergent, which are easy and safe to use at the same time, are therefore in demand.
TASK
It is an object of the present invention to provide an alternative cleaning method for removing milk residues, especially dried milk residues. Another object is to provide an alternative and effective composition for removing milk residues, especially dried milk residues. In particular, the cleaning of coffee machines, milk bottles, baby bottles, and other containers for milk and milk containing products is to be enabled or improved. In particular, the cleaning of apparatus or equipment is to be enabled or improved, the containers and / or piping systems are used for heating milk or milk-containing liquids.
The aim is also a cleaning agent and cleaning method for cleaning milk processing plants, in particular milk processing plants in coffee machines or other apparatus and equipment in which the milk is heated to provide.
In addition, provision, transportation and storage of the detergent should be simple and inexpensive. In particular, a cleaning agent is desired which provides the user in solid form, i. e.g. as a powder or tablet, can be supplied and provided.
Of particular interest is a relatively good and quick cleaning; in particular, a rapid dissolution of the cleaning agent is desired insofar as it is present as a powder or tablet, so that the maximum possible cleaning power of a given amount of cleaning medium of a tablet or a powder in Essentially achieved. In addition, a good stability of the cleaning agent is preferably required a certain shelf life of the cleaning agent.
DESCRIPTION OF THE INVENTION
The above objects and objects are achieved according to the invention by a method and a cleaning composition for removing milk residues, which are characterized in that the composition comprises at least one combination of at least one bicarbonate (ie Hydfogencarbonat), at least one carboxylic acid and at least one oxidizing agent includes. The at least one oxidizing agent is preferably at least one persulfate, especially potassium peroxomonosulfate (e.g., oxone).
The cleaning composition is in solid form, i. for example as a tablet and / or powder.
In a preferred embodiment, the composition of a cleansing tablet or cleansing powder for removing milk residues consists of the combination of one or more bicarbonates (i.e., hydrogencabonate), one or more carboxylic acids, and one or more oxidizing agents. Wherein, as the oxidizing agent, preferably persulfate, in particular potassium peroxomonosulfate (e.g., oxone) is used.
The combination of the ingredients of the composition results in a short dissolution time of the composition, especially in water. A particularly short dissolution time of e.g. below 5 minutes, preferably below 3 minutes, is particularly advantageous for the user, as it ensures that within a short time the entire amount of the composition used is available for cleaning.
In addition, advantageously, a fast and high cleaning effect is achieved in contamination with milk residues.
Advantageous embodiments will be described below.
The said composition is expediently such that it dissolves bubbly. The combination of carboxylic acid and bicarbonate, in particular citric acid and sodium bicarbonate, leads in particular to the property of effervescent dissolution on contact with water.

1 after cleaning: test plates G1 and P1 after cleaning with a solution of dissolved composition according to application example 1 and test plates G2 and P2 after cleaning with a reference solution. APPLICATION EXAMPLE 1 Exemplary composition of a 2.6 g tablet.
This tablet is also referred to below as tablet AB1. APPLICATION EXAMPLE 2 Comparison of the cleaning effect of a commercially available tablet for coffee machine cleaning (referred to below as tablet VI) with a tablet having the composition (AB1) described in application example 1: two flat transparent glass test plates (designated G1 and G2) each with three spaced in a line drops of milk on it overnight dried.
There are two concave curved transparent plastic test plates (designated P1 and P2), each with three spaced apart in a line drops of milk dried overnight.
All four test carriers (G1, G2, P1, P2) have visible white milk residues on the next morning after the milk has dried (see FIG. 1).
In a first experiment, a tablet (AB1) of the composition described in Application Example 1 (i.e., 2.6 g) is dissolved in a beaker with 500 ml of water (at room temperature [RT]). The dissolution time of the tablet (up to the visible complete dissolution) is 2 to 3 minutes. Glass test slides G1 and plastic test tiles P1 are immersed in the solution in the beaker. After 3 minutes, glass test tiles G1 and plastic test tiles P1 are removed from the beaker and dried with a hair dryer. G1 has no visible residue. P1 has few residues which, however, do not necessarily adhere to where the dried milk residues were located before cleaning.
In a second experiment, two commercial tablets VI (two times 4 g) are dissolved in a beaker with 500 ml of water (at room temperature). The dissolution time of the tablets (up to the visible complete dissolution) is about 10 minutes. Glass test slides G2 and plastic test tiles P2 are immersed in the solution in the beaker. After 3 minutes, glass test tiles G2 and plastic test tiles P2 are removed from the beaker and with a hair dryer
dried G2 and P2 have clearly visible milk residues. In fact, no cleaning effect can be seen. More information about VI can be found in the application example 3 table.
A visual comparison of the test slides shows that glass test slides G1 and plastic test plates P1, which were treated with a solution of the composition according to Embodiment 1 (AB1), little or no milk residues, while glass test slide G2 and plastic test slide P2, which with the commercial comparison product (VI) were treated with significant residues.
