kyFor some, the Perfect Life is Natural Fruit Juices
FrontLine™ - Widestream
®
Plate Heat Exchangers
.
Application
Pasteurisation and general cooling/heating of fruit juices and other
liquid food products which contain pulp or fibres.
Working principl
e
A plate heat excha
nger consists of a pack of corrugated metal plates
with port holes f
or the passage of two fluids between which heat
transfer will ta
ke place.
The plate pack is assembled between a fixed frame plate and a
movable pressure plate and compressed by tightening bolts.
The plates are fitted with a gasket which seals the inter
-plate channel
and directs the fluids into alternate channels. The number of plates
is determined by the flow rate, physical properties of the fluids and
the temperature program.
Connections may be located in frame plate and pressure plate and if
multi section PHE, also in connection plate.
The WideStream
®
plate
The WideStream
®
plate has a special pattern with few contact points,
which allows products containing pulp & fibres to pass without
blocking the passages. This results in long operational times without
interruptions. The ports have a diameter enabling cleaning in place
(CIP) with the same flow used in the process itself. The minimum
of contact points between the WideStream
®
plates results in easy
cleaning with short cleaning cycles. The plate pattern is designed for
efficient backflushing with free reverse flow.
The WideStream
®
plate can be used together with other plates in
the same heat exchanger frame.
