Способ стерилизации жидкого продукта на основе молока включает косвенный предварительный нагрев продукта и окончательный нагрев до температуры стерилизации 140-150oC путем прямой инжекции пара. Продукт охлаждают путем так называемого мгновенного охлаждения, при котором испаряется количество пара, соответствующее количеству добавленного пара. Продукт охлаждают путем косвенного охлаждения. В способе предложено перед мгновенным охлаждением охлаждать продукт от температуры стерилизации 140-150oC до температуры в интервале 90-120oC на первой стадии косвенного охлаждения, после которой продукт охлаждают путем мгновенного охлаждения до температуры 70-85oC. Установка для стерилизации содержит емкость для взвешивания 1, соединенную с первым теплообменником 4 косвенного действия для нагрева продукта на основе молока. Сопло для инжекции пара 6 расположено в выходном трубопроводе теплообменника 4. За соплом для инжекции пара 6 расположены секция выдержки 8 и вакуумируемая емкость 10, в которой продукт охлаждается путем мгновенного охлаждения. Между секцией выдержки 8 и вакуумируемой емкостью 10 установлен дополнительный теплообменник косвенного действия 9 для охлаждения продукта.

The method of sterilizing a liquid milk-based product involves indirect preheating of the product and final heating to a sterilization temperature of 140-150 o C by direct injection of steam. The product is cooled by so-called instant cooling, in which the amount of steam evaporates corresponding to the amount of added steam. The product is cooled by indirect cooling. In the method, it is proposed to cool the product from a sterilization temperature of 140-150 o C to a temperature in the range of 90-120 o C in the first stage of indirect cooling, after which the product is cooled by instant cooling to 70-85 o C. weighing container 1 connected to the first indirect heat exchanger 4 for heating the milk-based product. The nozzle for steam injection 6 is located in the outlet pipe of the heat exchanger 4. Behind the steam injection nozzle 6, there is an extract section 8 and a vacuum tank 10, in which the product is cooled by instantaneous cooling. An additional indirect heat exchanger 9 for cooling the product is installed between the holding section 8 and the vacuumized container 10.
