Tetra Pak Tetra Therm Aseptic Visco Line for pasteurisation /
sterilization of concentrated beverage bases by a Tubular Heat
Exchanger (THE) system. Capacity 2.600 up to 8.150 liter per hour. At
the current plant the line is used for products up to 100 °C. The
indirect heating temperature is up to a maximum of 135 °C. Holding
time set at 0 / 5 / 10 seconds. CIP Cleanable., In the Tetra Therm
Aseptic Visco system, heating and cooling will take place in Tetra
Spiraflo MTC tubular heat exchangers. Modules with a narrow ring
section are used for heating and cooling to ensure optimal heat
transfer. The product is pre-heated in stages within the Spiraflo
tubular heat exchangers. The Spiraflo tubular heat exchanger is
equipped with a sliding O-ring system. This means that the product and
the outer tubes are not welded together. This prevents stress
corrosion cracking and minimizes maintenance costs., The Tetra system
is pre-sterilized with hot water before production begins. Separation
of product and media during start-up and shutdown of the system is
done by a Brix measurement system. Once the system is ready for
production, the product flows to the product pump, which pumps it
through the pre-heating section to the first high-pressure non aseptic
homogenizer. This unit then forces it through the heater, via the
holding tube (0/5/10 seconds) and the pre-cooler, into the second
aseptic homogenizer (± 60 °C). The homogenization temperature is
automatically controlled in both cases. Since the capacity is
flexible, adjustment to the required output is achieved via
corresponding control loops using frequency converters in the
respective units. The selected heating temperature is set by means of
indirect heating via hot water circuits.The product is then cooled to
the desired filling temperature using a cooling tower and /or glycol
water., Line existing out of:, - Feed-Module mounted on a frame work
