METHOD OF PRETREATING MILK IN MICROFILTRATION

摘要

The invention relates to a method of pretreating milk before the milk is to be microfiltered. The method includes the method steps that raw milk (1) is heated and separated into a cream fraction (5) and a skimmed milk fraction (4). A milk fraction (11) which constitutes at least the skimmed milk fraction (4) is caused, at a temperature of approx. 50-55°C, to stay for at least two minutes in an open vessel (12) before the milk fraction (11) is led further to the microfiltration.
