The following targets seem to
be contradictory:
"A high demand on flexibility, product quality, production
safety and the efficient use of energy."
Tuchenhagen Dairy Systems has proved that these targets can be
achieved at a high level with its new UHT plant design. A core
element of the new UHT plant design is the product-to-product
indirect heat exchange in special tube bundles. The wide variety
of products our customers are capable of producing through the
UHT plant proves how flexible it can be.
The new approach
In indirect UHT-plants a high temperature transfer (approx. 90%)
is generally achieved by regenerative heat recovery. Where a
heat transfer to the product occurs through a water circuit
between the product to be heated and the product to be cooled.
In contrast to this concept the new indirect UHT plant provides
the product-to-product heat exchange and replaces the water
circuit with the heat directly from the heated product.
Therefore a higher temperature difference is possible, which in
turn increases the regenerative heat recovery without impairing
the product quality.
