Milk preheating is a fundamental requirement for the efficient and reliable cleaning process, as well as for the optimal separation of milk from impurities and contaminants through the cream separator (clarifier).
Proper preheating reduces the viscosity of the milk, facilitating the centrifugal separation process. As a result, higher cleaning efficiency is achieved, solid particles are removed more effectively, and the overall quality of the final product is improved.
The preheating system consists of two heat exchangers:
-
The first heat exchanger uses steam to heat water.
-
The second heat exchanger, utilizing the hot water, indirectly heats the milk, gradually raising its temperature to approximately 40–45°C, which is considered ideal for the separation process.
Indirect heating ensures a uniform temperature increase without thermal shock, preserving the natural properties and quality of the milk. In the final stage, the preheated milk enters the cream separator, where the cleaning and separation of unwanted impurities take place, ensuring hygienic processing and high product quality.
