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.
