Evaporater for Milk Processing Evaporated milk is a sterilized product, light creamy color. The product finds a large market in tropical countries. It is used where fresh milk is not available. It is also used as a substitute for breast milk, in which case Vitamin D is added. It is also used in cooking and as a Coffee/Tea Whitener.
The manufacturing process for the evaporated milk involves precision standardization of the fat content and the dry solids contents. This is followed by heat treatment which partly destroys the microbes present in the milk so that the risk of coagulation of milk is avoided in the subsequent sterilization process.
In the manufacturing of evaporated milk, the heat treated milk is fed to an evaporator, where it is concentrated up to 26% (8% Fat and 18% SNF). The milk is then homogenized before being cooled. Checks are carried out on the coagulation stability of the milk before it is packaged in the sterilized cans. The product is then placed in an autoclave for sterilization. Finally the cans are cooled before storage. The different stages in the production of evaporated milk are: -
- Standardization
- Evaporation
- Homogenization
- Cooling & Inspection
- Packaging
- Sterilization
- Cooling
- Storage
