Pasteurized Liquid Dairy

Pasteurization is the most commonly used heat treatment method for fresh market milk and SPX FLOW's experience in this basic process is extensive.

Pasteurization is applied to a product with the aim of avoiding public health hazards arising from pathogenic bacteria in the milk. The level of heat treatment is determined by the need to reduce harmful micro-organisms to a level which does not constitute a significant health risk. In addition, the level of chemical, physical and sensory changes in the milk must be minimised. Increasingly, the choice of Pasteurization conditions is also being focused on extending the keeping quality of the milk.

SPX FLOW's in-depth knowledge and active involvement in the development of the world's dairy industry, combined with proven experience in project management of both small and major capital projects, makes us the ideal partner for the design and installation of state-of-the-art Pasteurizing equipment.

SPX FLOW can supply any kind of APV milk pasteurization lines with capacities from 50-200,000 l/h.
