Automatic Small Scale / Mini UHT / Pasteurization Dairy Milk
With a product that can be stored for long periods without spoiling
and with no need for refrigeration, there are many advantages for both the producer, the retailer and the consumer.
This includes expensive products such as cream,desserts and sauces.In a modern UHT plant (Ultra High Temperature) the milk is pumped
through a closed system. On the way it is preheated, highly heat treated, homogenised, 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 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
