FIELD: food industry.SUBSTANCE: inventions group relates to the dairy industry. For the manufacture of 2.5% fat sterilised milk product the method is performed in the following way. While stirring, one adds dry a defatted milk residue and a stabiliser to a water filtrate and skimmed milk mixture for joining dehydrated milk fats and dry milk substances. The milk fats are dissolved and added to the mixture. The mixture is stirred, homogenised, pasteurised, cooled and maintained; the product is packaged and sterilised. Preliminarily skimmed milk is supplied by means of a pump into the heat exchanger where milk is heated to 45°-48°C and delivered into the bactofuge. By means of the pump milk is supplied into the microfiltration unit where 6.9-8.9" ceramic filters are applied, their throughput capacity equal to 1.1-1.6 mcm at a temperature of 48°-53°C. The filtrate is delivered into the pasteuriser where it is maintained at a temperature of 56.5°-58.5°C until an alkaline phosphatase test yields a negative result. Then the produced mixture is cooled to a temperature equal to 4-6°C in the heat exchanger and is stored in intermediate vessels.EFFECT: inventions group ensures preservation of the product natural composition and taste properties.4 cl, 2 dwg, 2 tbl |
