The invention relates to a method and apparatus for the treatment of raw milk. According to the method is separated from the raw milk under the effect of gravity a cream fraction, which is recovered. According to the invention, an inert gas is fed into the raw milk in order to promote the separation of cream. The apparatus comprises a gas-tight container (1), in the low portion of which there are arranged means (13) for introducing and bubbling gas into the raw milk fed into the container. In the upper portion of the container there is in this case formed a nozzle (11) that can be connected to a source of reduced pressure. According to the invention, a gentle separation of cream (fat) from raw milk is attained. At the same time, oxygen is removed from the raw milk, whereby the preservability of the raw milk and the cream separated can be improved considerably. |
