Tetra Pak® Pasteurizer PF
Efficient pasteurization for ambient or hot filling Prepared Food production
Application
Maximizing versatility and efficiency
The Tetra Pak Pasteurizer for prepared foods is an investment efficient and versatile continuous processing unit. It
is aimed for indirect heating and cooling of desserts, fruit
preparation, soups, sauces, tomato preparations and baby
food as well as other low or high acid viscous products
with or without particles. The unit can be equipped
with different types of heat exchangers, depending on
application. The pasteurizer is available as a stand-alone
unit or as part of a complete line concept.
Tetra Pak Pasteurizer PF, makes it possible to produce
high quality products at low operation costs. Using heat
generation design, when applicable on water side, it
offers optimized energy consumption in a wide range of
regenerative heating.
®
Highlights
• Available with either tubular or plate heat
exchangers to optimize configuration for best
design and efficiency
• Featuring consistent high food quality, enabled
by full traceability with the Advanced Automation
Solution Tetra PlantMaster™
• Ensures uncompromising food safety, due to high
hygienic design elements according to EHEDG
• Optimizes operational efficiency, due to long running
time and minimized energy consumption
• Adaptable cleaning program to secure food safety
and optimized production efficiency
• Guaranteed performance, e.g. running time,
product loss etc.
Tubular heat exchanger with floating protection system
minimizes maintenance and eliminates cracks in the tube.
For corrosive products, such as ketchup, corrosion-resistant
material like SMO254 is used. Protection panels in stainless steel lower the energy losses with up to 15%. Straight
tubes enable visual inspection if needed. Plate heat exchanger with optimized chevron and distribution pattern
maximizes heat transfer efficiency. The plate heat exchanger
is easy to open, which minimizes downtime at service. For
products containing high salt content, e.g. soy sauce,
titanium plates are used.
The unit offers optimal versatility with possibility to produce
a wide range of products at different viscosities, smooth or
with particles up to 9 mm in diameter. Option with aseptic
hibernation function saves energy up to 75% during sterile
water circulation. The optional pressurised internal sterilisation loop minimizes energy consumption during start-up
and water circulation. Advanced automation for reduced
human error and maintained product quality. Logging of
process parameters enables traceability for food safety.
Working principle
Capacity
The module is fully automated using PLC control for safe
operation and production. The operation can be divided
into four steps:
• Pre-sterilization
• Production
• Intermediate cleaning
• CIP (Cleaning-In-Place)
The capacity range for Tetra Pak® Pasteurizer depends on
the application, see example in chart. For other capacities,
please contact your Tetra Pak representative for more
information.
Before production can start it is necessary to sterilize the
aseptic area of the unit by circulating pressurized hot water.
An internal sterilizing loop minimizes the energy consumption
and start-up time. After sterilization the unit is cooled down
step by step to production temperature. Finally, sterile water
is circulated through the production unit.
When the receiving equipment is ready production starts by
filling the unit with product, displacing the water to drain.
The water/product mix phase can be sent to drain or reject
tank. Thereafter continuous production is running.
If product supply or receiving equipment fails, sterile
water displaces the product and the pasteurizer goes into
sterile circulation. The product is heated in either tubular
or plate heat exchangers by an indirect hot water circuit.
The product passes through a holding tube for the required
period of time. A temperature guard automatically monitors
the product temperature after the holding tube.
If the temperature drops below the pre-set value, an alarm
will be activated, production will automatically cease and the
receiving equipment will close. Cooling to filling temperature
takes place in additional tubular or plate heat exchangers.
In order to prolong the production period between CIP, an
intermediate cleaning can be performed. When intermediate
cleaning is selected, the product is displaced by sterile water
before cleaning starts. During the intermediate cleaning
sequences, the holding tube is kept at the sterilization
temperature, thus the aseptic parts in the module remain
sterile. The intermediate cleaning can be performed either
with lye only or lye and acid flush. This enables longer
available production time on the pasteurizer before full
CIP is required. After each production run, the module
undergoes CIP with both lye and acid. The CIP sequences
can be configured for optimized cleaning result.
