Tetra FlexDos™
Aseptic in-line dosing

Application
Tetra FlexDos provides flexible and safe in-line ingredient
delivery. Examples of ingredients that are suitable for aseptic
dosing by the Tetra FlexDos system include: enzymes, aromas,
colours, lipids, probiotic bacteria and other nutritionals. The
system ensures the survival and stability of heat sensitive function
that the charachteristics of the ingredients are not changed. It fits
with any filling machine with a capacity between 1 000 - 20 000 l/hr
with a continuous flow. The Tetra FlexDos is fully automated and
installed between processing and the filling machines. It can serve
one or several filling machines.

Working principle
The ingredient is injected into the base product with high
precision after the final heat treatment, just before the filling into
retail container. The pump section has two identical stations that
enable either single or double dosing depending on capacity and

number of ingredients injected. Each station can dose 0.5 l/h to 15
l/h of ingredient. A flow meter and a bar code reader ensure the
correct dosage level and product.
The dosing is made through a sterile hose connected to the bag
and a sterile needle injects the ingredient into the base product.
Steam and sterile condensate barriers maintain the aseptic
condition during the process. The liquid ingredient is pre-packed
through an aseptic process and kept in 5 or 10 litre bags, which are
ready to use. The Tetra FlexDos is euipped with an advanced
information system that provides total traceability. The unit does
not have a CIP and sterilisation system by itself but follows the
process cleaning and sterilisation process. The Tetra FlexDos unit
is controlled via its operator panel.
