This invention relates to the dairy industry, milk sterilized whole milk or reduction, and possible long-term storage and improved having a sense of accepting (organoleptic) characteristics, can be used to prepare the acid milk products that are based on the above.The invention of more attention to sterilization of milk, and secondary contamination of products in all manufacturing steps provides removal0.4 to the present invention is 0.7 g / l to the amount of the range of formula milk-soluble acid made by performing the milk treatment process and the subsequent operation in the presence of polyphosphoric acid derivative makin consists of dairy production process:HO- [PO 3 X] n -PO 3 X 2[wherein, X represents ions of sodium, or potassium, or calcium, or magnesium, or hydrogen, or ammonium, is 30 n 1] Milk processing is carried out as a double sterilization, bottling and packaging is accompanied by a seal at the temperature of 68 to 72 , balhyoje after the addition region is added into a sealed balhyoje milk under UV irradiation after packing the product end seal achieved. The present invention is also a milk processing method, first at a temperature of the milk 68 to 72 after sterilization, for the drinking of milk and held for more than 5 minutes for at least 15 minutes, acid dairy products, sealing the bottle which is accompanied by the injection temperature is performed after the maintenance of, and then sealed milk is cooled to a temperature of from 12 to 37 and held at this temperature for 30 minutes or more, after the second sterilization is maintained at a temperature of 68 to 72 , 10 / S consists of a method to be performed by heating the milk to over heating rate. The present invention also provides for the implementation of the structural design of the line of the production process of dairy acid, comprises a structural design of the milk treatment device for the implementation of the milk handling.본 발명은 낙농 산업에 관한 것이고, 살균 전유 또는 환원우유, 및 장기보존 가능하고 개선된
