Niro has the experience and ability to provide you with the right technology for your dairy evaporation application. 50 years of development has taught Niro what works and what doesn't so that you can have confidence in your Niro plant.
To make good powder it is essential that the feed concentrate to the dryer is of the highest quality. The right choice of evaporation technology is essential to achieve this optimum feed.
It is essential to evaporate milk correctly to achieve the required feed characteristics. Inappropriate evaporation can cause increased viscosity and product instability that may make drying more difficult or even damage the product irrevocably. Many functional powder properties, such as solubility, heat stability and the WPNI index are set at the evaporation stage. Some, such as the denaturisation of whey proteins, and colour & flavour development, are irreversible.
The correct properties are achieved by managing all the heating and handling processes within the evaporator plant to ensure the desired result. These properties can include: low heat powder for minimum product damage, medium heat powder (e.g. for baking applications), high heat (heat stable) powder with the correct properties to accept UHT treatment after reconstitution, and whole milk powder with the desired WPNI levels for easy reconstitution.
Systems are also designed to achieve the maximum plant efficiency, with the minimum downtime, and the desired balance between steam and electricity use.
