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.
