With a product that can be stored for long periods without spoiling
and with no need for refrigeration, there are many advantages for
both producer, retailer and consumer. This includes expensive
products such as milk, cream, desserts and sauces.
In a modern UHT milk production line (ultra high temperature) is
pumped through a closed system. On the way it is preheated, highly
heat treated, homogenized, ultra-highly heat treated, cooled and
packed aseptically. Low acid (pH above 4.5 – for milk more than pH
6.5) liquid products are usually treated at 135 – 150C for a few
seconds holding, by either indirect heating or direct steam
injection or infusion. High acid (pH below 4.5) products such as
juice are normally heated at 90 – 95C for 15 – 30 seconds holding.
All parts of the system downstream of the actual highly heating
section are of aseptic design to eliminate the risk of reinfection,
include aseptic packaging in packages protecting the product
against light and atmospheric oxygen. Ambient storage is normal.
Various UHT milk processing systems:
There are two main types of UHT systems on the market.
- In the direct systems the product comes in direct contact with
the heating medium, followed by flash cooling in a vacuum vessel
and eventually further indirect cooling to packaging temperature.
The direct systems are divided into:
•steam injection systems (steam injected into product),
•steam infusion systems (product introduced into a steam-filled
- In the indirect systems the heat is transferred from the heating
media to the product through a partition (plate or tubular wall).
The indirect systems can be based on:
•plate heat exchangers
•tubular heat exchangers
•scraped surface heat exchangers
Furthermore it is possible to combine the heat exchangers in the
direct systems according to product and process requirements
