Dirt of milking equipment is a dry soil of milk, a milk film to which proteins, fats and minerals are overlapped and adhered, and a protein and an inorganic substance that are difficult to remove due to incomplete washing of the milk film are left and accumulated. Milk scales in the form of film or scales, and heat treatment equipment include mortar, etc. on which a mixture of heat-denatured protein and fat and minerals is deposited.

Poor cleaning of milking equipment has been cited as the largest cause of bacterial contamination of raw milk. Conventionally, as a cleaning agent for a milking apparatus, an alkaline cleaning agent or an alkaline cleaning agent containing a chlorine agent is generally used for cleaning fat and protein stains remaining in the apparatus after completion of the milking operation.

また、装置内に蓄積した乳スケールや乳石を溶解除去す

いる。
Further, an acidic cleaning agent such as urea nitrate is regularly used for the purpose of dissolving and removing milk scale and calculus accumulated in the apparatus.

(発明が解決しようとする問題点) これに対して、酪農業界は年々厳しくなる国際化と輸入
の自由化等の諸問題が山積し、一層の生産コストの引き
下げに努力することが余儀なくされている。
(Problems to be solved by the invention) On the other hand, the dairy industry has been accumulating various problems such as internationalization and liberalization of imports, which are becoming severer year by year, and it is unavoidable to make efforts to further reduce the production cost. There is.

一方、消費量は、より高品質、安価な牛乳・乳製品を強

However, with conventional alkaline detergents, if the washing temperature is too high, milk protein causes thermal coagulation to make washing difficult, and if the washing temperature is too low, the fat content is not sufficiently emulsified, resulting in insufficient washing. This will cause milk scale deposition.

On the other hand, milk scale and calculus accumulated in the device are proteins,
Since the fat and the inorganic substances are irregularly entangled and formed, there is a problem that the conventional acidic detergent alone cannot be easily dissolved and removed.
