UF Unit
A milk UF (Ultrafiltration) unit is a piece of industrial equipment used to separate components within milk based on molecular size. It's a membrane filtration process that concentrates milk proteins while retaining essential minerals and lactose.
How it works
- Milk Feed: Raw milk is pumped into the UF system.
- Membrane Filtration: The milk is forced through a series of membranes with specific pore sizes. Proteins, minerals, and lactose pass through the membrane, while larger components like fat globules and bacteria are retained.
- Permeate and Retentate: The liquid that passes through the membrane is called permeate, which is primarily water with some lactose and minerals. The concentrated liquid retained by the membrane is called retentate, rich in proteins.
- Concentration: The retentate can be further concentrated to produce products like milk protein concentrate (MPC).
