With correct and regular milk system cleaning ,the inside of the milk pipe is always hygienic. But various bacteria and germs may collect over time on the outside of the milk pipe. They may come from particles in the air or through contact with hands. If the milk pipe is inserted straight into the milk, the bacteria are transferred into the milk.Optimum milk quality is no longer guaranteed. For perfect milk quality everytime, we recommend using our milk containers, which are the product of intensive research and development. The closed system with a docking point for the milk pipe creates the ideal conditions for storing fresh milk.
